Seabirds, from cormorants to puffins, spend most of their lives at sea. Beloved by birdwatchers, these animals can be hard to study because they spend so much time far from shore.

New research led by the 91̽ uses data collected by coastal residents along beaches from central California to Alaska to understand how seabirds have fared in recent decades. The , published July 6 in the journal Marine Ecology Progress Series, shows that persistent marine heat waves lead to massive seabird die-offs months later.

“This is truly a global data set that asked a global-sized question: Does a warming world significantly impact marine birds, among the top predators in the nearshore marine environment?” said co-author , a professor of aquatic and fishery sciences at the 91̽and executive director of the Coastal Observation and Seabird Survey Team, known as .

Cassin’s auklets are seen in April 2016. This was the first massive mortality event following the onset of “the blob.”

“We find a dramatic delayed effect,” she said. “A warmer ocean, and certainly a suddenly warmer ocean as happens during an El Niño or a marine heat wave, will result in the death of hundreds of thousands to millions of marine birds within one to 6 months of the temperature increase.”

Marine heat waves have only recently gained attention. They include the unusually warm ocean surface off the Pacific Northwest nicknamed “” that persisted from 2014-2016, as well as prolonged El Niño events and warmer oceans in Alaska associated with retreating sea ice.

The 91̽team’s previous research linked recent ocean warming to individual die-offs among seabirds, including common murres, Cassin’s auklets and . This study takes a broader approach.

“Rather than track the specific numbers of any one species, this study measures the magnitude of mortality events, regardless of seabird species, above long-term normal,” Parrish said. “We asked: What rate are carcasses washing in, over what portion of coastline, and for how many months? Larger-magnitude events are those that push up all these measures.”

The study used surveys of beach-cast birds from 1993 to 2021 between central California and Alaska. Truly massive mortality events, with death tolls most likely exceeding a quarter million birds, occurred roughly once per decade. But between 2014 and 2019, five events met this mortality threshold.

“This is unprecedented. This type of massive die-off can be compared to a catastrophic storm that we would usually expect once per decade; they happen, causing massive damage, but usually there is enough time for areas to recover,” said lead author Timothy Jones, a 91̽research scientist in aquatic and fishery sciences. “From 2014 to 2019, the die-offs were not only some of the largest ever documented, but they kept happening year after year — like a catastrophic storm hitting without fail every year.”

Analysis shows that these extraordinary die-offs were statistically linked to persistently warmer conditions in the Northeast Pacific in the preceding months. Some birds, including murres, puffins, auklets and shearwaters, suffered much more than others.

The study included more than 90,000 surveys of 106 seabird species on more than 1,000 beaches, collected by four citizen science projects. The largest area was covered by the UW-based COASST program, spanning northern California to Alaska. Additional data came from and , both in central California, and the , in Canada. These organizations train participants to search local beaches for dead birds and submit their findings.

Additional data for remote northwest Alaska beaches came from community members’ reports to the U.S. Fish and Wildlife Service and Alaska Sea Grant.

The data show that carcasses began to wash up a few months after the warming began and followed a roughly three-year pattern. The exact cause of each die-off is different, but all are related to warming. Warmer water can promote harmful algal blooms and increase the likelihood of disease outbreaks, both of which provoked seabird mortality events during the study period. Most notably, prolonged ocean warming changed the type, abundance and nutritional value of seabirds’ prey, leading to widespread starvation, the authors said.

“With this intensity of warming, like the looming El Niño in the Pacific or the current marine heatwave in the North Atlantic, we are facing a new ocean,” Parrish said. “One with fewer birds.”

Beach trash accumulates in predictable patterns on Washington and Oregon shores /news/2022/08/23/beach-trash-accumulates-in-predictable-patterns-on-washington-and-oregon-shores/ Tue, 23 Aug 2022 16:01:46 +0000 /news/?p=79341 Colorful trash displayed on sand

Citizen scientists recorded trash on Pacific Northwest beaches, from southern Oregon to Anacortes, Washington, to contribute to the growing study of marine trash. A study by the 91̽ analyzed 843 beach surveys and found that certain beaches, and certain areas of a single beach, are “sticky zones” that accumulate litter.

The was published online Aug. 11 in Marine Pollution Bulletin.

“Thousands of volunteer hours allowed us to investigate what is driving the rubbish washing up on our beaches, and where it’s ending up,” said lead author , a 91̽visiting scientist who is a postdoctoral researcher at the Commonwealth Scientific and Industrial Research Organization, or CSIRO, in Australia. “Understanding how trash moves through the marine environment provides us with important clues to identify sources and implement strategies to prevent more trash escaping.”

All the data were collected by volunteers with the Coastal Observation and Seabird Survey Team, or COASST. The UW-based citizen science effort began in the 1990s to study seabirds. In late 2015 the team added a group of volunteers focused on .

The new paper uses observations of medium-sized refuse, between 1 and 20 inches (from the width of a thumbnail to the length of a forearm), from 2017 to 2021. Volunteers collect data year-round at distinct zones on each beach.

“Trained volunteers with COASST are able to go out and observe many locations with a frequency that just wouldn’t be possible any other way,” Willis said.

The study used statistical analysis to confirm that some parts of the beach are “sticky zones.” One such natural resting spot for garbage is the so-called wrack zone, the high-tide mark where kelp and other organic material accumulates. The other place trash likes to land is the wood zone, where driftwood washes up in storms and comes to rest. In general, beaches with more organic flotsam also tended to have more litter.

Results also showed very different patterns for the 36 beaches surveyed in Puget Sound compared with the 27 beaches surveyed on the outer coast of Washington and Oregon. In the protected waters of Puget Sound, about half the waste was plastic, with the rest being heavier objects like metal, glass or cement. This suggests that Puget Sound litter tends to originate from that area or neighboring beaches, according to the authors.

But on the outer coast, 90% of the observed items were plastic, mainly broken-down fragments of larger objects. The litter on the outer coast also showed a strong seasonal pattern, with more trash in the spring after winter storms, and lower litter levels in the fall.

“In populated areas of Puget Sound, what the data suggest is that if you see a lot of trash, someone probably dumped it or it escaped accidentally nearby,” said co-author , Science Coordinator at COASST. “But if there’s a lot of trash in a remote region, the people who live there are not necessarily the people who are creating that trash — they’re just the ones who are dealing with it once it lands.”

Knowing where and when beach litter tends to accumulate could help improve programs that collect and remove trash. The findings could also help managers evaluate strategies to prevent beach litter, such as launching educational campaigns around marine waste, installing secure trash bins, and banning plastic bags and other single-use products.

“A lot of times people say: ‘There’s trash out there, let’s just go out and clean it up,’” Lindsey said. “But we need to also take a step back and use science to document how things happen in the system upstream, looking at the source of the problem to target our responses.”

Volunteers’ surveys showed that non-plastic items like metal, glass and cement are more common on Puget Sound beaches than on the outer coast. Researchers say this suggests most of the litter in Puget Sound is generated locally. Photo: Kathy Willis/91̽

Results show that the total amount of beach trash in the region dipped slightly from 2017 to 2021, but the authors caution that it’s too early to know that it’s a downward trend.

“It’s really exciting to have this baseline data,” Willis said. “We now know what type of rubbish is showing up in this region and what is driving it, so in the future we’ll be better able to evaluate how things might be changing.”

Other co-authors are , and at the UW, and Hillary Burgess at the National Oceanic and Atmospheric Administration. The research was supported by a grant from the Australian-American Fulbright Commission and by the more than 280 volunteers who collected data on the beach.

‘By-the-wind sailor’ jellies wash ashore in massive numbers after warmer winters /news/2021/03/18/by-the-wind-sailor-jellies-wash-ashore-in-massive-numbers-after-warmer-winters/ Thu, 18 Mar 2021 19:43:10 +0000 /news/?p=73349

As their name suggests, know how to catch a breeze. Using a stiff, translucent sail propped an inch above the surface of the ocean, these teacup-sized organisms skim along the water dangling a fringe of delicate purple tentacles just below the surface to capture zooplankton and larval fish as they travel.

At the mercy of the wind, these jellies can wash ashore and strand — sometimes numbering in the trillions — on beaches around the world, including up and down the U.S. West Coast. And while these mass stranding events are hard to miss, very little actually is known about how or why they happen.

Now, thanks to 20 years of observations from thousands of citizen scientists, 91̽ researchers have discovered distinct patterns in the mass strandings of by-the-wind sailors, also called Velella velella. Specifically, large strandings happened simultaneously from the northwest tip of Washington south to the Mendocino coast in California, and in years when winters were warmer than usual. The were published March 18 in the journal Marine Ecology Progress Series.

“Citizen scientists have collected the largest and longest dataset on mass strandings of this jelly in the world,” said senior author , a professor in the 91̽School of Aquatic and Fishery Sciences and executive director of the Coastal Observation and Seabird Survey Team, known as .

“This paper contributes to fundamental scientific knowledge of this organism in a way that traditional ‘mainstream’ marine science has been unable to do. Thousands of trained, dedicated observers are better than any satellite because they know their beach and can alert us if something is weird or unusual.”

COASST’s citizen scientists are trained to search for and identify carcasses of marine birds that have washed ashore at sites from northern California to the Arctic Circle. Participants are asked to record and submit photos of anything strange or different they see on their stretch of beach.

In 2019, program managers received an email from COASSTers in Oregon who had expected to see Velella on their beach based on past observations, but hadn’t. That prompted COASST scientists to comb the database — 23,265 surveys in total — to see if others had taken note of these jellies over the years. This “data-mining” returned 465 reports of Velella littering 293 beaches, often in more than one year.

“On the water, Velella are beautiful, fragile creatures. When they wash ashore, these jellies quickly dry to the consistency of potato chips. During a mass stranding it’s like walking on a crunchy carpet,” Parrish said. “So of course, COASSTers reported in. Suddenly, we realized we had the largest dataset about Velella velella anywhere in the world.”

In analyzing the citizen science observations, 91̽researchers discovered that most by-the-wind sailors wash ashore on West Coast beaches during the spring, when the winds shift and push the organisms to shore. However, their analysis also revealed truly massive stranding events in 2003-2005 and again in 2015-2019. During the later years, jelly carcasses covered more than 620 miles (1,000 kilometers) of continuous coastline, all within a single two-week window between mid-March to mid-April.

The second period corresponds with the timing of the long-lasting marine heat wave known as “the blob” — also to blame for the largest seabird die-off of common murres, as well as mass die-offs of Cassin’s auklets, sea lions and baleen whales.

The researchers hypothesized that warmer winters during these years allowed for populations of by-the-wind sailors to spike in the open ocean. Then, when the winds shifted in the spring, massive numbers of the jellies were swept to shore and stranded.

Put another way — and though many ultimately end up dying on beaches — the jellies appear to be “winners” during warmer periods, because they can amass more numbers in the ocean. There’s some evidence that warmer-than-average winters are also calmer and less wavy in the open ocean, allowing increasingly large Velella aggregations to persist, Parrish explained.

“This paper and our data really do suggest that in a warming world, we’re going to have more of these organisms — that is, the ecosystem itself is tipping in the direction of these jellies because they win in warmer conditions,” Parrish said. “A changing climate creates new winners and losers in every ecosystem. What’s scary is that we’re actually documenting that change.”

As warmer winters are expected to increase with climate change, these findings could have clear implications for this jelly population, as well as for the fish they eat and the beaches where they strand and die.

‘The blob,’ food supply squeeze to blame for largest seabird die-off /news/2020/01/15/the-blob-food-supply-squeeze-to-blame-for-largest-seabird-die-off/ Wed, 15 Jan 2020 19:04:41 +0000 /news/?p=65673 dead common murre

The common murre is a self-sufficient, resilient bird.

Though the seabird must eat about half of its body weight in prey each day, common murres are experts at catching the small “forage fish” they need to survive. Herring, sardines, anchovies and even juvenile salmon are no match for a hungry murre.

So when nearly one million common murres died at sea and washed ashore from California to Alaska in 2015 and 2016, it was unprecedented — both for murres, and across all bird species worldwide. Scientists from the 91̽, the U.S. Geological Survey and others blame an unexpected squeeze on the ecosystem’s food supply, brought on by a severe and long-lasting marine heat wave known as “the blob.”

Their were published Jan. 15 in the journal PLOS ONE.

“Think of it as a run on the grocery stores at the same time that the delivery trucks to the stores stopped coming so often,” explained second author , a 91̽professor in the School of Aquatic and Fishery Sciences. “We believe that the smoking gun for common murres — beyond the marine heat wave itself — was an ecosystem squeeze: fewer forage fish and smaller prey in general, at the same time that competition from big fish predators like walleye, pollock and Pacific cod greatly increased.”

nest in colonies along cliffs and rocky ledges overlooking the ocean. The adult birds, about one foot in length, are mostly black with white bellies, and can dive more than two football fields below the ocean’s surface in search of prey.

Warmer surface water temperatures off the Pacific coast — a phenomenon known as “the blob” — first occurred in the fall and winter of 2013, and persisted through 2014 and 2015. Warming increased with the arrival of a powerful El Niño in 2015-2016. A number of other species experienced mass die-offs during this period, including , Cassin’s auklets, sea lions and baleen whales. But the common murre die-off was by far the largest any way you measure it.

From May 2015 to April 2016, about 62,000 murre carcasses were found on beaches from central California north through Alaska. Citizen scientists in Alaska monitoring long-term sites counted numbers that reached 1,000 times more than normal for their beaches. Scientists estimate that the actual number of deaths was likely close to one million, since only a fraction of birds that die will wash to shore, and only a fraction of those will be in places that people can access.

Many of the birds that died were breeding-age adults. With massive shifts in food availability, murre breeding colonies across the entire region failed to produce chicks for the years during and after the marine heat wave event, the authors found.

“The magnitude and scale of this failure has no precedent,” said lead author , a research biologist at the U.S. Geological Survey’s Alaska Science Center and an affiliate professor in the 91̽School of Aquatic and Fishery Sciences. “It was astonishing and alarming, and a red-flag warning about the tremendous impact sustained ocean warming can have on the marine ecosystem.”

From a review of fisheries studies conducted during the heat wave period, the research team concluded that persistent warm ocean temperatures associated with “the blob” increased the metabolism of cold-blooded organisms from zooplankton and small forage fish up through larger predatory fish like salmon and pollock. With predatory fish eating more than usual, the demand for food at the top of the food chain was unsustainable. As a result, the once-plentiful schools of forage fish that murres rely on became harder to find.

“Food demands of large commercial groundfish like cod, pollock, halibut and hake were predicted to increase dramatically with the level of warming observed with the blob, and since they eat many of the same prey as murres, this competition likely compounded the food supply problem for murres, leading to mass mortality events from starvation,” Piatt said.

As the largest mass die-off of seabirds in recorded history, the common murre event may help explain the other die-offs that occurred during the northeast Pacific marine heat wave, and also serve as a warning for what could happen during future marine heat waves, the authors said.

91̽scientists recently identified forming off the Washington coast and up into the Gulf of Alaska.

“All of this — as with the Cassin’s auklet mass mortality and the tufted puffin mass mortality — demonstrates that a warmer ocean world is a very different environment and a very different coastal ecosystem for many marine species,” said Parrish, who is also the executive director of the , known as COASST. “Seabirds, as highly visible members of that system, are bellwethers of that change.”

What motivates people to join — and stick with — citizen science projects? /news/2019/07/23/what-motivates-people-to-join-and-stick-with-citizen-science-projects/ Tue, 23 Jul 2019 19:38:26 +0000 /news/?p=63282 From searching for extraterrestrial life to tracking rainfall, non-experts are increasingly helping to gather information to answer scientific questions.

One of the most established hands-on, outdoor citizen science projects is the 91̽-based , COASST, which trains beachgoers along the West Coast, from California to Alaska, to monitor their local beach for dead birds.

With about 4,500 participants in its 21-year history and roughly 800 active participants today, COASST’s long-term success is now the subject of scientific study in its own right. What makes people join citizen science projects, and what motivates people to stick with them over years?

A UW-led published in the July issue of explores the interests and identities of participants who join and remain active in citizen science. Results could help other science projects aiming to harness the power of large teams.

Previous research led by the 91̽has shown that people who join online-based citizen science projects generally try it just once, and fewer than 1 in 10 remain active past one year. The rates for hands-on, in-person efforts are much higher: COASST, for example, has 54% of participants still active one year after joining.

But what separates those who stay from those who go? Years of responses to surveys from the COASST team’s recruitment and engagement efforts provide a unique window on citizen science.

“I came to the 91̽to analyze a gold mine of social science datasets accumulated by COASST,” said social scientist and lead author , a postdoctoral researcher in the 91̽School of Aquatic and Fishery Sciences.  “Over a four year period, hundreds of participants responded to survey questions about why they were joining – or continuing – with the program. This represents an unparalleled opportunity.”

Recently COASST helped pinpoint a major in fall 2016 along the Alaskan coast. The timing and location of carcasses found by volunteers suggested that the mass strandings might have been caused by unusual ocean conditions.

She analyzed answers to two freeform questions posed to project participants: “Why did you join COASST?” and “Why do you continue to be involved in COASST?” Some 310 new participants chose to answer the questions during their initial training. Another 623 seasoned participants, who had been involved for more than one year, completed a mail-in survey.

“People’s memory can be a bit tricky,” He said. “You may think that two or five years ago you had a particular motivation, but is that really so? With this study we can definitively answer the motivation question at two different times: at the moment of joining the program, just after they finish being trained, and once they have spent at least a year on the beach collecting monthly data.”

The analysis shows that new participants wanted to be outdoors on the beach, learning about birds. Many listed their scientific degrees, previous occupations and birding expertise. But responses from longer-term contributors displayed a slightly different pattern: Although birds and beach remained dominant interests, seasoned volunteers were more likely to mention interests such as the desire to monitor and observe their beach, help in making scientific discoveries, and the importance of project data and results for environmental conservation. Moreover, their “science identity” became focused on their data-collection team and the project collective, rather than on their personal traits.

One important finding, He said, was the value of place. Volunteers often mentioned the importance of continuing to visit their beach even if they hadn’t found any birds washed ashore after several months.

“We thought they would talk a lot about birds, and they did, but they actually talked more about the coastal environment, the beach and the ocean,” He said. “Place was either equally important or even more important to them than birds.”

Another surprising finding is the degree to which participants consider citizen science to be a social activity.  Of the five tasks volunteers listed as most important in defining their work for COASST, two – “communicating project results” and “recruiting others to participate” – were social.  The other three tasks were “collect data,” “make measurements” and “enter data.”

“Activities that help connect family members and friends, and provide opportunities to meet new people who share similar interests, can also be scientific in nature,” He said.  “COASST fulfills both science and social interests for coastal residents.”

The study’s conclusions based on the surveys included some take-home messages for organizers of hands-on citizen science efforts:

  • Long-term participants tend to be motivated by a project’s mission and goals, and successful programs communicate scientific findings back to participants so that they can see their individual contribution as part of the big picture of project results.
  • Experienced participants focus on where they conduct their project activities, indicating that sense of place is important to volunteers.
  • Both new and long-term participants focused on their social interactions as a central part of project activities, suggesting that successful hands-on, citizen science combines high-quality scientific activity with building and maintaining social relationships.

 

The research was funded by the National Science Foundation’s Advancing Informal STEM Learning program and Washington Sea Grant’s support for COASST. Other authors on the paper were , a 91̽professor of aquatic and fishery sciences and director of COASST, , a 91̽postdoctoral researcher in aquatic and fishery sciences, and , an associate professor at Oregon State University.

Parrish is lead author, with co-authors including Jones and He, of another , published in February in the Proceedings of the National Academy of Sciences, exploring the relationship between participant retention over the long term and accuracy of data collection, which also revealed the importance of social networks in citizen science. That analysis looked at 54 citizen science projects, including COASST, to pinpoint the characteristics of and determine how citizen science projects can be designed for maximum success and reach.

“Both of these papers indicate that attention to social and scientific aspects of the project are likely to return the highest quality data,” said Parrish. “Attention to friends, family, community and other aspects of individual identity will make a difference in the success of our recruitment efforts.”

Ocean warming, ‘junk-food’ prey cause of massive seabird die-off, study finds /news/2018/06/05/ocean-warming-junk-food-prey-cause-of-massive-seabird-die-off-study-finds/ Tue, 05 Jun 2018 16:35:08 +0000 /news/?p=57879

In the fall of 2014, West Coast residents witnessed a strange, unprecedented ecological event. Tens of thousands of small seabird carcasses on beaches from California to British Columbia, in what would become one of the largest bird die-offs ever recorded.

A network of more than 800 citizen scientists responded as the birds, called , turned up dead in droves along the coast. Beach walkers and local residents recorded the location and date of carcasses as they found them, entering the information into a real-time database that helped state, tribal and federal wildlife experts track the mass mortality event as it unfolded.

The efforts of these place-based data collectors — along with data on temperature, ocean circulation and the abundance of prey — have provided the first definitive answer to what killed the seabirds: starvation, brought on by shifts in ocean conditions linked to a changing climate. An international team of about 20 researchers from federal, state and provincial agencies, universities and wildlife organizations in the April 16 edition of Geophysical Research Letters.

“This paper is super important for the scientific community because it nails the causality of a major die-off, which is rare,” said senior author , professor in the 91̽’s School of Aquatic and Fishery Sciences and executive director of the (COASST), one of the citizen science groups that counted the carcasses.

“When we see these mass mortality events, that’s the ecosystem saying, in big neon letters, that something is wrong. This paper can be used as definitive proof of the impacts of a warming world, and it’s a not a pretty picture,” Parrish added.

The team’s paper pinpoints starvation as the cause of death for between 250,000 and 500,000 Cassin’s auklets in late 2014 to early 2015. The birds’ main source of prey, aquatic zooplankton known as krill and copepods, was found to be smaller and less abundant than in previous years, forcing the seabirds to eat less nutritious “junk food” instead of their usual nutrient- and energy-rich prey.

See a related story in 

Cassin’s auklets are palm-sized, stocky seabirds known for their remarkable ability to fly underwater in search of food. They are a gregarious species that nest in colonies and migrate south along the coast in early fall, after breeding.

Warmer surface water temperatures off the Pacific coast — a phenomenon known as “” — first occurred in the fall and winter of 2013, and persisted through 2014 and 2015. This event was the likely culprit for shifting the zooplankton “dinner table” toward less nutritious species, the researchers found. Energy-rich copepods thrive in colder water. When the massive marine heat wave spread along the coast, it swept in loads of smaller, less nutritious copepods typically found in warmer southern waters.

Through the summer of 2014, ocean circulation kept the blob at bay in the Pacific Northwest, creating a coastal wedge of cold water full of energy-rich food just off the coast of Oregon and Washington. But that refuge collapsed in mid-September when seasonal shifts in ocean circulation changed. As a result, Cassin’s auklets migrating south after breeding off the coast of British Columbia essentially lost their nearshore foraging habitat.

This study is the first to document the direct link between marine heatwaves and marine bird mortality events, the authors said.

“A lot of the evidence points to there being a very tangible link in the warming of the Pacific to changes in ecosystem structure that ultimately led to seabird starvation,” said lead author Timothy Jones, a 91̽postdoctoral researcher in aquatic and fishery sciences.

The warm “blob” of the Pacific Ocean for more than three years. After the auklet die-off, four more mass mortality events involving seabirds took place, occurring farther north each time. Murres, puffins, and most recently short-tailed shearwaters and northern fulmars in the Arctic experienced a similar fate as the auklets — as far north as the Chukchi Sea.

“The Cassin’s auklets story is really the opener of a saga of multiple seabird die-offs that are unprecedented, as far as we know,” Jones said.

The story of the auklet die-off is likely to repeat for other species under climate change, Parrish said. Researchers will continue to draw upon and learn from this example.

“This was a unique opportunity to have a window into the future,” she said. “We are getting a sense of what the largescale ecosystem — the entire North Pacific up into the Bering and Chukchi seas — might look like in the future, and where we will have winners and losers and how we might see change. In that sense, it was a tremendous natural experiment.”

The efforts of hundreds of beach walkers — many of whom survey their local beach for seabird deaths each month — combined with databases and the knowledge of scientists across many fields cracked the mystery of the Cassin’s auklets with a level of precision that is hard to replicate, the authors said. Critical to their success was the ability to collaborate and share resources.

“The big lesson here is you have to work together in the sandbox. No one on this author list has any hope of doing all that work by themselves,” Parrish said. “We had incredible luck in that citizen scientists were collecting for years the very data we needed to find the cause.”

This study was funded by the National Science Foundation and the Washington Department of Fish and Wildlife. The full list of co-authors is listed in the paper.

What if every coastal community along the entire Pacific Rim were involved in monitoring their local marine environment, and all of that data were brought together in one place? Imagine, for example, if residents in Long Beach, Washington, could submit information about seabirds they observe, then look up bird data from another coastal community in southeast Alaska to compare notes.

Think about the possibilities if new data were combined with traditional knowledge to bound climate impacts, or if local knowledge contributed to oceanography.

These are lofty goals, but a team of researchers led by the 91̽ believes creating a network of community-based science is possible with new support from the National Science Foundation.

The grant comes from the agency’s new , which seeks to improve access to STEM education and careers by reaching more underserved populations, including the dozens of small, remote communities dotting the Oregon, Washington and Alaskan coastlines. The UW-led project is one of 37, totaling $14 million from the National Science Foundation.

“Almost everyone has a story about how the local outside environment that’s important to them is changing,” said , lead investigator and associate dean for academic affairs in the UW’s College of the Environment. “We aim to create something that is community based and community driven and shakes hands with mainstream science that we call the Coastal Almanac.”

The almanac, Parrish explained, will be two things: A physical network of people living in coastal communities — along with researchers from universities, colleges and agencies — and a digital collection of data that are curated and shared online.

“We see a future where every single coastal community has hundreds of people involved in data collection and data use, helping to make the decisions about natural resources in their backyards,” Parrish said. “The Coastal Almanac is a way of extending the discovery space and the solution space of science to include more people and ideas.”

Parrish, a fisheries professor who founded and directs the 17-year-old citizen science group (COASST), worked with at Western Washington University and at Oregon State University to submit the Coastal Almanac proposal. The National Science Foundation money will support a two-year pilot phase, with the goal of further funding.

More than 600 proposals were submitted for the prestigious INCLUDES awards, which will support both tried-and-true methods of engagement, as well as “edgy” projects that could bring big rewards if they succeed, Parrish explained.

“Our project is big and risky,” she said. “Trying to flatten the science landscape to truly involve everyone is a tough challenge. But I think 91̽is exactly the right place to do this, because we are an incredible powerhouse of information and expertise. We have it within us to speak with, and work with, everyone.”

During the first two years, the team will launch a Coastal Almanac website and determine the most effective ways of posting and sharing information. Hatch and Heppell will reach out to tribal nations and fishery organizations, respectively, while Parrish will focus on citizen science groups.

The 91̽will likely host the almanac’s central administrative hub, but Parrish said most of the activity will happen in coastal communities, as residents collect data on subjects as varied as weather, beach erosion, marine mammal sightings, invasive species and flower timing.

“In today’s quickly changing world, science needs to be a team sport,” Parrish said. “If everybody could participate in meaningful science without having to be scientists — how might we make decisions differently, as communities, as a society?”

The INCLUDES grant comes on the heels of another National Science Foundation award to the 91̽— Active Societal Participation In Research and Education (ASPIRE) — that will support early career researchers in the geosciences who wish to work more collaboratively with rural and/or underrepresented communities on issues that geoscience can address.

In total, the 91̽and its collaborators are receiving $700,000 in funding to encourage community-driven science, especially among underrepresented groups.
