Getting the Scoop on Scat:
River Otter Diets in Makah BayBy Bobbie Buzzell, Western Washington University
I remember the fi rst European green crab I saw,
beautiful and distinctive, but also intimidating —
its reputation preceded it. It was hard to believe this
single species of crab could be the reason for such
concern within natural resource departments
across Washington state. The European green crab
is an invasive shore crab (native to Europe as the
name suggests), and its arrival into our state’s waters
over the last few decades poses a serious threat to
native fl ora and fauna along the outer coast
and inland waters.

Teaching During the Pandemic (Covid-19) By Alice Ryan, Quileute Tribal School
I was asked to write about teaching during this crazy pandemic year. The following is a disjointed mess of emotions, situations, and regular daily experience to…pretty accurately, sum it all up.

When green crab establish and reproduce,
they can severely harm local habitats,
which is why the sight of even a single green crab is cause for concern.
On the Makah Indian Reservation, more
than 3,700 green crabs have been trapped on the Wa’atch and Tsoo-Yess
river estuaries over the last few years. Adrianne Akmajian, marine ecologist
for the Makah Tribe, believes green crab are here to stay “…we are already seeing
the young 2021 brood and have hand caught over 80 crabs… I suspect that in
addition to the larvae that may come from other areas, they are reproducing locally
here in Makah Bay.” In high numbers, this voracious crab damages coastal
eelgrass beds, and can cause declines in shellfi sh and native crab populations as
seen in places on the East Coast. For the locals in Washington, shellfi sh lovers are
worried about what this might do to the beloved (and valuable) Dungeness crab.
Currently, early detection and removal
through trapping are the only forms of control for green crab. A lack of control
options, coupled with a knowledge gap on how green crab could infl uence coastal
ecosystems, leaves natural resource managers looking for answers. Some of
those answers might include identifying the predators of green crab, which is what
happened in 2018 when trapping efforts led to the discovery of a river otter latrine
along the lower Wa’atch River. River otter latrines are communication hubs where
this aquatic mammal routinely defecates, urinates, and leaves their scent. Adrianne
describes coming across the latrine, “I had not planned for it, I immediately
converted bags that were going to be used for green crab and began col-
lecting river otter scats, just in case.”
Alas, my master’s thesis was born! Around the same time the latrine was found, I was
looking to return to school to pursue a master’s degree. I had previously studied
river otter diet in the San Juan Islands, so I was already familiar with the fare of
river otters in marine-coastal habitats and methods in scatology (the study of
feces). My advisor at Western Washington University (WWU) connected me with
Adrianne. One thing led to the next, and in early 2019 I was hired by the
Makah Tribe and received approval from the Tribal Council to begin fi eld

work collecting scats at several latrines
on the lower Wa’atch and Tsoo-Yess
rivers. My objective was to document river otter diet in the area of where
green crab trapping takes place, with the hope of understanding the role
of green crab in river otter diet.
From April through September 2019, I collected scats and prepared the
leftover hard parts for identifi cation. Collecting scat and identifying undigested
remains (e.g., fi sh bones, crab shells) is a no-harm way to document diet. One
piece of prey at a time, this method has been used for decades to understand
connections between organisms. Identifying prey from leftover hard
parts is like a jigsaw puzzle with a lot of missing pieces. A jawbone here, a crab
claw there… With enough fragments, a full fi sh or crab can be identifi ed.
It wasn’t just me working on this puzzle
though. I had help from other technicians and high school interns with the Makah
Tribe that summer, and later undergradu-ate assistants at WWU. Could there be
a more fun way to introduce students to ecology than teaching them about poop
puzzles? Chaya Gaberria, one of my undergraduate assistants at WWU, wanted
to learn more about mammals. She said the project “ allowed [her] the opportunity
to delve into the prey patterns of river otters and gain a deeper understanding
of their diet.” She also developed techni-cal skills with microscopes and learned
how to identify fi sh and crustaceans.
Then in March of 2020 the pandemic hit, and labs were either shut down or heavy
restrictions were put in place, making the lab where I worked inaccessible. Due to
the restrictions, I was unable to keep my assistants. Thankfully, scats and a micro-
scope are fairly portable, so I brought scatology back to my humble abode. As
summer approached, continued closures on campus meant my home would be my
new lab. Despite these changes, funding from NPC MRC allowed me to fi nish
crustacean identifi cations before the next school year started. Although
I had enough experience to identify crabs and crayfi sh, I brought in an expert to
identify the fi sh prey. But even he could be stumped! William “Bill” Walker has spent
decades identifying prey remains from animal stomach contents and feces but

described river otter diet as “an elaborate
forensic exercise.” He told me that part of
the challenge with river otter diet is that they thoroughly chew their food into bits
prior to ingestion. Despite how broken up the prey were, bones and shells were
in good condition, which speaks to how quickly river otters digest their food.
As I worked through each scat, the
optimism I had for river otters eating a lot of green crab slowly faded. There
was a decent bit of Dungeness crab and crayfi sh, but only a handful of the 447
scats from latrines on the Wa’atch River contained green crab. No green crab
were found in the 227 scats collected from latrines on the Tsoo-Yess River. This was
disappointing, but since I could look at the
whole diet of these river otters, the other jigsaw pieces would help me understand
why so few green crab had been eaten.
If river otters aren’t eating green crab, then what are they eating? The results
were a bit overwhelming! While only a handful of prey items were found in more
than 10% of scats, there were at least 50 different fi sh, crustaceans, and other
miscellaneous prey groups discovered in river otter diet. Bill expressed his take on
the complexity of river otter prey, “they will eat just about anything they encounter
in their immediate environment.”
Fish were the dominant prey type, and the most frequently found species was the
saddleback gunnel, a small eel-like fi sh
(maximum size about 10 inches) that commonly inhabits estuaries, tidepools,
and eelgrass beds of the coast. What was most interesting about this fi sh though,
was river otters frequently consumed it with many other gunnels. Some scats
contained as many as 200-300 individuals! Similarly, other small fi sh prey like various
sculpins (bottom-dwelling fi sh), starry fl ounder (fl atfi sh), bay pipefi sh (cousin
to the sea horse), shiner perch and three-spine stickleback (schooling fi sh) were
frequently consumed in large quantities. “From an energetic cost standpoint,
I believe it unlikely these fi sh were consumed individually”, said Bill,
“I suspect that individual otters are engaging in some form of feeding
strategy that involves herding these

small fi sh into concentrations where they
can consume multiple fi sh at a time.”
Of crustacean prey, “young” (sub-adult)
Dungeness crab were consumed more frequently on the Wa’atch River while
signal crayfi sh were more commonly consumed on the Tsoo-Yess River. It was
surprising that no green crab were eaten on the Tsoo-Yess despite there being
more green crab trapped there than on the Wa’atch. Differences in green crab
abundance between the two rivers were dwarfed by the overall abundance of
Dungeness crab. In other words, Dungeness crab were overwhelmingly
more common than green crab. I believe this was one reason why fewer green
crab were eaten by river otters. Given
what is known about river otter diet in other coastal studies, this is reasonable
since otters choose prey opportunisti-cally, consuming the most abundant
and accessible of slow-moving prey.
When it comes to hunting, the river otters that made a “contribution” to this study
are in a unique living situation. Not only can they forage in the lower and upper
sections of the rivers, they also have access to the surrounding wetlands and
shallow areas of Makah Bay. The range in their hunting grounds shows through in
the vast array of fi sh and crustaceans they consumed. In human terms, it’s compa-
rable to the variety of cuisines one might fi nd at a mall food court. You have Asian,
Italian, sandwiches and subs — you name it!
However, if the green crab numbers continue to increase in Makah Bay,
I predict green crab will be like the McDonald’s of the 1940s, bound to be a
staple at every food court in the future.
It’s important to note though, green crab behavior might also be a reason why they
are not frequent fare of river otters. Green crab are especially aggressive and river
otters probably don’t have the easiest time wrangling this feisty prey. From
experience, I know green crab are good at hiding in the main river channels where
river otters mainly forage. One of the best tricks for hand catching this
crustacean is to probe and disturb areas around logs and driftwood on
the bottom of the rivers, scaring green

crab out of hiding. Perhaps river otters
haven’t caught on to this trick yet?
Very few river otter diet studies have been
able to document diet in as extensive detail as this one has, and this information
provides a lot of context for not only why green crab have a limited role in river
otter diet but also what the role of river otters are in Makah Bay. Understanding
the big picture of ecosystems starts with knowing how both prey and predators
infl uence each other. Given the quantity of small crabs and fi sh river otters eat
on a daily basis in Makah Bay, it’s safe to assume they might provide balance
to food webs in the estuaries, keeping prey populations “in check”, and in turn
may allow other animals to thrive.
River otters aren’t the only ones consuming green crab though. Predators like shore
birds, fi sh, and other crabs may be a cumulative defense against the growing
threat. In fact, the red rock crab, a native crustacean to rocky intertidal zones
on the west coast, has already proven to provide some resistance against
this invasive crab. Supporting these predators and their homes could be key
to reducing green crab. It’s unlikely river otters on their own will end the impend-
ing invasion, but a robust community of predators will maximize chances to
buffer impacts of green crab.

• It’s early March 2020: China is experiencing this Covid thing;
it is an epidemic. My students and I are playing a board game
called “Pandemic” as a way of talking about this event going on across the sea…
• People are contracting it in the U.S. now… California has its
fi rst case of unknown origin that my students noticed. Wash-ington state starts getting cases, a lot of cases. Seattle is a
scary place to go, and where many of my students need to go for medical appointments. Each time they were nervous, and
even more so coming back to the tribe.
• The arrangements are all made, fi nally: A major fi eld trip planned for March 19th to our new school site. Grades 6
through 12 are all going. We’re building the school to get our classes out of harm’s way in case of a tsunami, and the fi eld trip
there is about watershed restoration. We have about seventy plants named and ready to plant; we’re going to pull invasive
weeds and do “Bonds Across the Water” (https://depts.wash-ington.edu/i2sea/index.php?page=batw) activities including
water quality testing and biodiversity data collection.
• March 14th. We are told to get Google Classrooms ready, and we teach our students how to access them while we were
learning how to make them at the same time. CRASH COURSE IN ONLINE LEARNING!!!
• It’s Monday, March 17th. The entire school is closing. Three
students join me that night to plant all of our plants as the sun starts to set, so that they won’t die while we wait for the school
to reopen. Perhaps it will be just a week or two, but we do not want to chance it. We get about one hour of warning that we
are not coming back to school tomorrow, so I take what I might need to teach. I might not be allowed back to campus. The
reservation is closing too.
• Reaching out to students is an “all approaches on deck” sort of situation. Some teachers try Snapchat. It doesn’t work for me.
Facebook Messenger, texting, calling, voice chatting. I even learned about TikTok. Anything and everything that we could
do to meet our students in their spaces we tried. Still some stopped connecting. Many students’ voices just fall off into the
nothingness, and I worry about them.
• Students who are doing their schoolwork do not need to follow the classic school schedule… I am getting calls at 9 pm,
11 pm, and even one at 2:30 am from students that are trying. That 2:30 am one was from a student I had been trying to get
in touch with, so you know I took that call.
• Getting students their supplies is a whole different kind of mess. I mask up and drive into the reservation. I call students
up on the phone and then throw their lab to them from a few feet away. We talk in loud voices, and I treasure these strange
interactions because I miss them so much.
• Sometimes I teach from my kitchen (most productive), sometimes the couch (more comfortable), and my favorite is
from the back yard. Giving students tours and talking about the strange things that I am doing and asking them about how
they are doing.
• I gave up calling some parents because they sound just as lost and frustrated as I am. They’re feeling overwhelmed and
like they were failing at keeping their kids working, keeping their own jobs going, keeping the house clean, and all of the
other expectations and now… they needed to help teach??? Especially diffi cult are the families with kids spanning a wide
age range. Elementary aged students need more support from parents. 7-12th grade students in these families had to
pitch in as teachers/parents themselves and, because of this, fall behind in their own schoolwork.
SUMMER IS FINALLY HERE!!! In all my years of teaching never has March – June lasted so very, very long…. Am still checking in with
students often.
This fall things changed. Teachers are all AT SCHOOL while students are AT HOME. Sitting at my desk, staring at the laptop
screen. Zoom is up and running. A full class now means almost half of my students, which makes fi ve of them. Five black squares
with white letters spelling out their names. Cameras are off — I can’t see them. Five mics are turned off. I am speaking though;
Is anyone home? I smile, I laugh, I act goofy, bring in Star Wars toys to interact with… I FAKE being upbeat. Nothing… Silence…
I ask questions. Wait. Wait Wait… A lengthy wait time doesn’t work when a period is only thirty minutes long and the students
are all more than ten minutes late, if they show up at all. I try not to cry till classes are over.
Students are missing – are they ok? I reach out to them without
response, I can’t just go to their houses, they are on the reserva-tion. I am ONLY allowed to go to work and back. I call, I text, a FB
message here, a Snap there, even a Tik-Tok… ARE my STUDENTS DOING OK? Am I doing OK? NO, I AM NOT.
SELF CHECK: How do I fi x this…. What am I not getting that would
help? I’d like to see their faces at least.

• Another day of Darkness, one-way conversations to little black
boxes with white names. The silence…. So quiet, I must talk
faster, talk more… fi ll the gap. It’s all a gap! It’s all worth it to
just to hear someone.
• How do I fi x this? OK. I need their videos on…. How How
How… TOYS?!? I will bribe them. I bought a bunch of toys –
$$$ well spent. For every fi ve classes that they’re visible online
through class, they got a toy. We would drive over to their
house and throw the toys to them.
• It WORKED. !!! Their faces helped pull me out of the darkness
a little bit more. Further from the edge, I was going to make it
through this, now I had at least one student in all but one class
who would turn their camera on for me.
• It’s March 2021, and we’re back in person with a seriously
modifi ed schedule. Still only three days a week, still only from
8am-2pm. BUT, we now had 70-minute classroom periods
which I love, and then a day of all 30-minute periods. There are
worries and concerns even now we are remote for the rest of
the week because we had two Covid cases in the school. I am
taking it in stride.
• Two weeks of Cohorts. That is, students stay in their advisory
groups. I am with my seniors as we work on a 7-12th grade
focus on digital citizenship. We are also preparing for gradua-
tion, helping them get caught up with their classes.
CONCLUSIONS, or so I think. Teaching is SO MUCH MORE than a
job, or a paycheck. It is the daily interactions, the good and bad,
happy, and sad ones. Students give me something… let’s call
it energy and it is tangible. Without it, I fall into darkness. This
is SOOO obvious now, and I share that with my students. Labs,
activities, students are getting caught up, most of my students are
present.
• Here we go again! May… almost to summer and now, LOCK
DOWN! I’m sent home with a partial day’s notice, with the
hopes of coming back on June 3rd. What to grab, what will I
need to teach from home?
• We were starting the dissections this week. I had one parent
beg me to still let her daughter do her dissection… got
permission, set up special permission slips, and brought her
a frog… Everyone else wants to wait – much to the relief of
parents… but what will we do until then? The physics class is
right in the middle of making Triboelectric Nano-Generators…
A whole giant box of supplies is involved for each student, and
very few of the boxes are labelled, so a bit of a guessing game.
They all need to get to the kids. Set up their bags, eggs go in,
copper, marbles, bouncy balls, can’t forget the lights…what
else can I throw in… I call my husband (who also works at the
school) and ask him to drive them out to the kids so that they
have their lab supplies.
• Almost 4pm almost ready to leave. OH NO! My Earth Science
class just started a lab about the effects of CO2 on muscles. I
carefully pull out each student group’s beakers, grab any notes
that they left on their containers just in case they did not write
them down, and weigh each shell, recording it all on a scrap
of paper.
• I am so tired, ready to head out. Grabbing the project, I am
working on for seniors, the supplies, anything I can think of
that I might need.
• Teaching From Home Again! First day of online. A few students
show up. Black squares with white names, black squares white
names… again.
• Paper dissection time. I know I will buy the paper fog
dissection kits with my own money, but its worth the cost,
and there is no way to go through the school fast enough.
Downloading …now print. I have enough ink, yay. And I didn’t
run out of paper. A call out for help with delivery, math teacher
to the rescue. Phew… I got them all passed out.
• Black screens, white names… silence. Bribe with toys again…
it helps. The teamwork I saw in class, gone, I beg, I ask them to
help each other out, put the cameras back on. One girl does,
and her mom jumps on excitement infectious as her daugh-
ter’s. TEN boxes light up with laughter. Another video feed
pops on, and another. I remind them of their teamwork in class,
and now they all have videos on, and they are mostly talking
and sharing. PHEW…
• The next period black screens, white names… Silence.
Please NOTE: I am lucky that I teach at the Quileute Tribal School;
there are so many ways in which the school bent over backwards to

The low-elevation terrace at Rialto Beach
is a geologic enigma. My team of gradu-
ate students and I are trying to unravel a complicated puzzle there. What is that
puzzle; why is it so complicated; and why do we care? We want to know the
origin of a low-elevation marine terrace that lines Rialto Beach and the northwest
coast of Washington. The answer is complicated because of the intermingling
of landslides, earthquakes, erosion, large windstorms, and sea level change. And
the origin could tell us about a previously unknown history of uplift and landslides,
related to earthquakes, on the coast.
As a geologist and faculty member, it is hard to fi nd a better place to conduct
research and teach than the outer coast

A Challenging Puzzle: Terraces, Landslides, and Earthquakes at Rialto Beach

of Washington. Besides the breath-taking
beauty and diverse ecosystems, the
geology is amazing with ample evidence of multiple glaciations, active erosion
and deposition, deformed bedrock, and many geologic hazards. My team has been
fortunate to have the support of the North Pacifi c Coast Marine Resources Com-
mittee, the U.S. Geological Survey, the 10,000 Years Institute, Olympic National
Park, Sea Grant, and the University of Washington (UW) to work out here for
four years now, mostly focusing on the origin of the terrace and the geologic
story it holds. The terrace is an enigma: why does it exist? It is of variable height
(3 to 6 feet) and variable width (100 to 200 feet) and contains deposits that tell
of many changes in the environment. At
the base of the terrace, we see a layer of older beach deposits that is over 400 years
old. That layer is buried by organic-rich layers and multiple landslide deposits
ranging in age from 200 to 700 years old. Pollen in the landslide deposits hints at
variations in the climate and shows that a slightly different assemblage of trees once
grew on the slope above the terrace.
Many landslides, originating on the slopes that are currently above the back of the
terrace, have spread across the beach in the past. What we see today is the
truncated toes of these landslides because the terrace is being eroded by waves.
The landslide deposits contain angular clasts of sandstone bedrock and so are
distinctive from the rounded and ovate
gravels in the beach deposits. We also fi nd a bounty of carbon-rich material to
date in the landslide deposits: sections of trees, limbs, stems, leaves, and Sitka
spruce cones. We have obtained several radiocarbon dates on wood and cones in
the landslide deposits and have learned that at one location, a landslide dates
to about 300 years before present. This location coincides with the most actively
eroding section of the terrace and is also the tallest section because of the greater
thickness of landslide deposits there. We plan to refi ne the date of that landslide
because, with an age of ~300 years, it could have happened because of shaking
during the 1700 AD Cascadia Subduc-tion Zone (CSZ) earthquake. Our next
step is precision dating using tree-ring

chronology and wiggle matching on
some of the bigger logs in the landslide
to see if death of the trees coincides with the exact year of that earthquake.
In addition to detailed sedimentology,
surveying elevations of the tops of the layers in the terrace will help us determine
if uplift created the terrace. Nowhere on the Washington coast has uplift been
documented from a CSZ earthquake. Subsidence has been documented
and correlated to the 1700 AD CSZ earthquake, but that evidence is well
south of Rialto Beach. Deformation models now suggest that uplift could be
possible. Finding uplift would change current expectations for land-level
change during the next earthquake, with implications for hazard mitigation.
Did earthquake shaking trigger landslid-
ing and uplift of a former beach surface forming the terrace at Rialto Beach? We
need to know what kind of land level changes could occur in the next CSZ
earthquake. And we need to know if such an earthquake would trigger landslides
along the coast. Those are the goals of our research. To get at those questions,
we must deal with more parts of the puzzle - sea level rise and rapid erosion.
We know from residents and scientists like Jill Silver (10,000 Years Institute) that
the terrace once extended tens of meters further seaward. In the short time that we

have been studying the terrace, we have
seen nine meters of erosion. This is a very
dynamic beach! Dying Sitka spruce trees are falling onto the beach from the edge
of the terrace and then being moved down beach joining other drift logs.
So, stay tuned for future updates on our
research as we refi ne our dating and mapping to determine the origin of the
low-elevation marine terrace at Rialto Beach. We hope to answer our ques-
tions so that we can contribute to our collective understanding of the geologic
hazards on the Washington coast, recur-rence intervals of those hazards, and
risks of damage from earthquakes.

Walking the beach in the early morning fog, I almost run into
the researchers before I see them. A crew of fi eld technicians is
busy at 6 a.m., moving a long hose into the saltwater in order to pump it into small, carefully located plastic cylinders twisted
into the sand. The crew is doing a survey of razor clams along the outer coast of Washington state. These surveys are conducted
during low tide series by the Washington Department of Fish and Wildlife, the Quinault Indian Nation, Hoh Tribe and Olympic
National Park. They occur every summer and cover every mile of beach where the clams occur. The water hosed into the sand
liquifi es it, and the razor clams fl oat to the top, where they can be counted, measured, and returned to the sand. The measure-
ments feed into the annual stock assessments that are used to set the recreational and commercial limits on this prized fi shery.
In a good year, razor clams are open to harvest all up and
down the coast, including fi shing by tribal members of the

Hoh and Quileute Tribes and the Quinault Indian Nation, and to
recreational fi shing by the general public. The razor clam fi shery
brings in tourists to small coastal towns and their visits are valued in the millions annually. However, the fi shery has not been opened
at all locations in all years. Kalaloch Beach has been partially or fully closed in most of the last twenty years due to various
combinations of high levels of domoic acid in the clam tissue, which can make humans sick, or a lack of older, harvestable
clams. While large numbers of clams are recruiting to Kalaloch Beach, they are not surviving past their second year, by which
time they normally approach a size that humans like to collect.
Between the summer of 1983 and the winter of 1984, razor clam populations in Washington state beaches declined by an estimat-
ed 95%, from about twenty million clams, to less than one million clams. A year later, microbiologist and pathologist Ralph Elston
identifi ed the likely culprit: a bacterial pathogen that he called nu-
clear inclusion X (NIX), which was infecting gill tissue of the clams.
The pathogen gets inside of the nuclei of the cells making up the gills and enlarges them, thereby disrupting the fl ow of seawater
and potentially causing clams to suffocate. Many of the dead clams that were found in 1983 had large amounts of mucus in the
gills, possibly a response to the infection. Surveys conducted by Dr. Elston and colleagues revealed that the pathogen was preva-
lent in most razor clams in state beaches throughout Washington and was not detected in clams from northern British Columbia
or Cook inlet, AK. Recently, the possible associations between NIX infections and clam mortality resurfaced because of the poor
survival in adult razor clams in Washington coastal beaches.
Olympic National Park coastal ecologist, Dr. Steve Fradkin, has raised the question as to whether disease may be killing these
clams after their second year. Thanks to funding from the North

Pacifi c Coast Marine Resources Committee, colleagues
at the USGS Western Fisheries Research Center were able
to help answer this question by fi rst developing two new molecular NIX identifi cation tests.1 The fi rst test uses an
assay called quantitative “polymerase chain reaction” (PCR) to quantify how much DNA of NIX is contained in a tissue
sample. The second test uses a molecular probe that binds to NIX DNA in tissue and can be seen under the microscope.
As the fog begins to burn off, I see wildlife feeding on clams.
Gulls, migratory birds, raccoons and coyotes are some of the animals that take advantage of these low tides to harvest a
delectable meal. We collect and preserve gill tissue in ethanol

so that we can quantify the level of infection in these clams.
Nearly all the clams we have tested so far are infected, so
the highly sensitive quantitative PCR test we use can help us distinguish between highly and lightly infected clams. Disease
is a part of all food webs, and the mere presence of a pathogen does not tell us whether or not it is contributing to mortality.
We are setting up a baseline monitoring program so that we can quantify infection levels and see if there are correlations
between high levels of infection and subsequent population reductions. In the next phase of our research, we will construct
spatial and temporal maps of infection and investigate how this pathogen contributes to the survival of these charismatic clams.

Olympic Coast ROV School Program
Navigates Challenging Waters During Pandemic
by Nicole Harris, National Marine Sanctuary Foundation
MATE, the Marine Advanced Technology and Education
organization, is leading the way in preparing the next generation
ocean work force. The hook is using remotely operated vehicle (ROV) technology to inspire and challenge students to learn and
creatively apply science, technology, engineering, and math (STEM) to solve real-world problems in a way that strengthens
critical thinking, collaboration, entrepreneurship, and innovation. Pre-pandemic, this was achieved through the hard work of
teachers, mentors and students building teams, solving problems and telling their stories at regional competitions around the
world, including the Olympic Coast MATE ROV Competition.
The realities of the Covic-19 pandemic changed the way students engaged with learning. Face to face interactions
and opportunities to work closely in teams to solve problems and engineer solutions weren’t allowed. The uncertainty of
being around anyone in those early days of understanding Covid-19 were strange and surreal and the 4th annual MATE
Olympic Coast ROV competition in spring of 2020 was cancelled, as were all MATE regional competitions. Then, we
all waited to see what the next academic year would bring.
And the next academic school year seemed to bring, well, more of the same. To reference Google Maps, we were
constantly “recalculating” our next turn, as restrictions related to Covid-19 never quite allowed for opportunities that could
support the efforts needed to build a competing team. They also never quite allowed for the return to an indoor, organized
event the size of our competition. And yet, we persevered.
With the continued support of our funders and the commitment of the amazing mentors and teachers supporting their students,
the Olympic Coast At-Home STEM Challenge was born. Funds were re-allocated to support kits that would be
distributed to participating students and all activities could be accomplished at their home.
The kit might look like a mish-mash of junk drawer “treasures”
— string, paperclips, electrical tape, PVC, tongue depressors, shrimp nets, craft wire, zip ties, wooden dowels — but to a
robotics student, it was the makings of a manipulator that could retrieve an object. And retrieving an object was the goal
they set out to accomplish when entering this challenge.
The Olympic Coast At-Home STEM Challenge provided kits to 28 students. Students could submit entries to all three chal-
lenges: the States of Buoyancy Challenge, the Manipulator Design Challenge, and the Object Retrieval Challenge. All
students who submitted an entry received a “participation prize” for overcoming the Covid-19 blues and rising to the challenge
of STEM at home. Additionally, three $50 and four $25 cash prizes were provided by the Surfrider Foundation Olympic
Peninsula Chapter to the following students based upon their entries: Kevin Ryan, Damian Colfax, Mica McCarter, Xavier
Johnson, Thalia Black, Denise Ward Bender, and David Ward.
The challenging waters of the Covid-19 pandemic may have knocked us back as a community committed to STEM engagement
for coastal youth, but it didn’t take us down. The future looks bright for MATE ROV on the Olympic Peninsula, with new projects
on the horizon and a rising group of students to bring into the world of underwater robots, marine technology and teamwork.

During Washington CoastSavers’ 15th annual Washington
Coast Cleanup (WCC) on April 17th, over 500 volunteers from
around the region hauled away over 12,000 pounds of plastic water bottles, household trash, lost fi shing gear, and other
types of washed-up debris that can kill or poison coastal wildlife
and spoil the natural beauty of our shorelines. This outcome
is especially impressive given the fact that twenty Olympic
National Park, Olympic Coast National Marine Sanctuary, and Makah, Quinault, Quileute, and Hoh tribal beaches, normally a
part of the annual cleanup, were closed during this time to help prevent the spread Covid-19. For these areas, CoastSavers put
out a call to action to local communities in proximity to some of these beaches to help reduce local waste streams and other
sources of marine debris. The Washington Clean Coast Alliance, the network of federal and state agencies and NGOs that runs
the CoastSavers program, also partnered with Olympic National Park to distribute cleanup toolkits to encourage solo cleanups
throughout the month of April 2021. These toolkits included garbage bags, gloves, datasheets, instructions how to use Ocean
Conservancy’s free Clean Swell data app (available through app stores), as well as Surfrider Foundation’s pamphlet ‘Break Free
from Plastic,’ and instructions on where to dispose of the debris.

As part of the springtime coast cleanup this year, 33
volunteers (sponsored by Clallam Bay Sekiu Lions, Clallam
Bay Chamber of Commerce, and CoastSavers.org) collected marine debris from the beaches on the northwest Strait of
Juan de Fuca. They removed 770 pounds of debris that could negatively impact habitats and wildlife. Bravo!
Several volunteers added another job to their day. Many
people would be happy to sort the recyclables into one bin, dump the rest in a landfi ll and go home. Citizen scientists do
more. One group of high school students and a Mom brought in 295 pounds of debris and dumped the huge piles of rope,
net, awkward shaped debris and full bags onto the ground. They sorted it into categories: plastic beverage bottles (60),
foam and plastic packaging (218), straws/stirrers (41), food
wrappers (60), and much more. The sorting of large items went quickly, the fi nal counting of tiny trash took the longest
time. Data was recorded on data sheets, and entered into the Ocean Conservancy interactive database and real-time
global map (https://www.coastalcleanupdata.org).
Why go to the trouble to sort and count and report? The information generated by citizen scientists (students, families,
senior citizens, community groups, a couple of friends) around the world provides a snapshot of the global ocean trash
problem and infl uences long term solutions. Throughout the year, small scale cleanups can be conducted along Washington
waterways. Plastic pollution and trash in the seas are big problems. Local citizen scientists are part of the solution.
