Video: Gary Greene on Exploring the Salish Seafloor

You don’t go looking for lions on the Arctic tundra or for grizzly bears in the tropical rainforest – that is if you hope to find them. The topside world presents a wide variety of biomes inhabited by plants and animals adapted to survive in each special place. Our underwater world is no different. However, for people working to recover the Salish Sea, it’s been harder to protect threatened marine creatures and their critical underwater habitats simply because it’s so difficult to find them.

Beneath the surface of the Salish Sea lie a dazzling variety of habitats. We all know about kelp forests and eelgrass meadows and the riot of life they support, but did you know that we have huge “sand waves” that shelter vast schools of sand lance and provide foraging environment for birds like Tufted Puffins and Rhinoceros Auklets? Or that all of the various bottom features scientists have identified – glacial moraines, earthquake-generated rock piles, vertical ice-cut rock walls and mud-filled bays and sounds – each support their own collection of animals?

SeaDoc’s exciting new Tombolo Seafloor Mapping Laboratory is addressing real-time conservation needs by pinpointing Salish Sea habitats. When your goal is to protect important marine creatures like our threatened rockfish species, you can’t get there without a map.

Salmonella in wildlife: presentation at North American Veterinary Conference

4277554959_2a874c7ea0_b.jpg

Salmonella has been isolated from various marine mammals, including California sea lions (shown here in a photo from Morro Bay, CA). At the 2014 North American Veterinary Conference, in Orlando, Florida, Joe Gaydos presented on Salmonella in wildlife. About 10% of the Salmonella outbreaks between 2006 and 2013 were caused by wild animals, and most of these were caused by reptiles and amphibians.

Salmonella infection can be prevalent in wild birds, and has been seen in many wild mammal species including white-tailed deer, raccoons, and river otters.

Relatively little is known about Salmonella in free-ranging marine mammals. It has been isolated from harbor porpoise (Phocoena phocoena), a killer whale (Orcinus orca), sea otters (Enhydra lutris nereis), northern elephant seals (mirounga angustirostris), California sea lions (Zalophus californianus), Northern fur seals (Callorhinus ursinus), and harbor seals (Phoca vitulina). Far more isolations have been made than actual documentation of disease. Salmonella Newport-associated septicemia has been documented in a harbor porpoise and a killer whale. Salmonella also has been isolated from marine birds such as Western gulls (Larus occidentalis). While one study found prevalence of Salmonella in 40% of California sea lion pups and 33% of northern fur seal pups on San Miguel Island, the prevalence in most marine wildlife populations is unknown but probably highly variable.

Joe Gaydos presents on river otter diseases at veterinary conference

7056954311_fae15edb22_b.jpg

7056954311_fae15edb22_b At the 2014 North American Veterinary Conference, held in Orlando, Florida, Joe Gaydos presented a paper on diseases in river otters.

Diseases of River Otters, A Recovering Species. (PDF)

River otters were nearly eliminated over much of their home range, but have made comebacks. They can be found in freshwater habitats ranging from alpine lakes to rivers, streams, and swamps. From California to Alaska they sometimes occupy a nearshore marine habitat, where they play an important ecological role. They depend on fresh water for drinking.

River otters are host to various bacteria, viruses, fungi, and internal and external parasites. Some of these can cause disease in humans and domestic animals.

River otters are also sentinels to evaluate environmental contaminants including heavy metals, hydrocarbons and persistent organic pollutants.

The paper includes findings on successful anesthesia and capture methods.

Coastal cutthroat trout in the San Juan Islands

Coastal-Cutthroat-by-J.-Galasow-562-326 (1)Coastal or sea-run cutthroat trout are freshwater fish that also move into the marine waters to feed and are an important recreational fishery in many parts of the Salish Sea. Many people don't think of the San Juan Islands when they think of cutthroat trout, but they were historically caught in the area. Long-standing residents recall a time when these rare fish were much more abundant. While recent work documented cutthroat trout in some streams in the San Juan archipelago, little is known about the current status of coastal cutthroat trout in this area.

Thanks to funding raised from private donors, the SeaDoc Society just awarded a grant to Long Live the Kings to analyze the abundance of coastal cutthroat trout in the San Juan Islands.

With collaborators at the Wild Fish Conservancy, Kwiáht, and the Washington Department of Fish and Wildlife, Long Live the Kings also will analyze the genetics and spawn-timing characteristics of cutthroat trout from multiple streams in the San Juan Islands to determine if there are unique stocks within each of the multiple watersheds and whether coastal cutthroat trout in the San Juans are a unique stock complex. This work will provide the basis for determining and prioritizing appropriate recovery efforts and measuring results after recovery begins.

The Bear Necessities

bear eating barnaclesBlue herons hunting for fish, bald eagles swooping on seabirds, river otters diving for crabs: links between animals and the ocean are common in the Pacific Northwest. These dependencies go much deeper than previously thought.

Seadoc’s Joe Gaydos and Scott Pearson (WDFW) recently compiled the first list of every bird and mammal species that uses our inland sea and its 16,925 km2 ecosystem – a huge task that involved tracing the web of life from forest to marsh to ocean.

Counting species is basic science, but without a baseline we would have no way to know how we’re doing in the battle to keep our ecosystem healthy enough to support both ourselves and wildlife. In making their list, Joe and Scott discovered some surprising facts:

Sea Star Wasting Disease

Sunflower-Sea-star-1.jpeg

Update January 21, 2016

SeaDoc recently spent 2 days at a sea star wasting disease summit hosted by the Seattle Aquarium.

Scientists from all over the US and Canada who are studying this disease came to share their research and learn from each other.

We still have a lot to learn about this disease, but data presented support: (1) this is an unsual mortality event, (2) the disease hits a wide range of sea star species, and (3) it affects different species of sea stars differently. Species that seem have been hit hard both in the wild and in captivity include the mottled star (Evasterias troschelii; pictured here), sunflower star (Pycnopodia heliantoides), spiny pink star (Pisaster brevispinus) and the ochre sea star (Pisaster ochraceus).

Joe Gaydos notes, "I'm impressed with and inspired by all of the great scientific minds working to unravel this mystery!" evasterias sea star j. gaydos

Update November 17 2014

SeaDoc was among dozens of collaborators that recently published a paper linking a virus to sea star wasting disease. The paper showed that a virus was involved in the massive outbreak that, since June 2013, has killed millions of sea stars (including more than 20 different species) along the west coast of North America.Interestingly, the same virus was found in museum specimens of sea stars collected 72 years ago, suggesting that a mutation in the virus (as has been seen with closely related viruses) could have triggered the outbreak.

Work is continuing to better understand the other factors involved in this outbreak and how this massive loss of predators will reshape the marine ecosystem.

Understanding emerging threats to the health of our oceans is a key part of SeaDoc's work, and donations to SeaDoc make it possible.

Read the paper by Ian Hewson, et al.: http://www.seadocsociety.org/?p=2949

Earthfix covered the study, noting that this virus is different from all known viruses infecting marine organisms. (Another little-known fact: a drop of seawater contains about 10 million viruses.)

Read it: Scientists find out what's killing west coast starfish

Smithsonian Magazine also has a good article about the study and what it means.

Update October 2014

The San Juans were largely skipped by the wasting disease outbreak last fall, but this summer they were hit hard. Drew Harvell's lab at Friday Harbor Laboratories did investigations all summer long, and were able to watch as the disease swept across the archipelago. For example, the Eastsound waterfront area experienced approximately 95% wasting disease prevalence. Water temperature appears to play a large role in the disease. Researchers have also worked to identify genetic factors that appear to make it possible for some sea stars to survive the disease.Collaborators Morgan Eisenlord and Drew Harvell recently published a summary of their summer's work on sea star wasting disease in the San Juan Islands in the the Friday Harbor Labs Tide Bites newsletter. http://depts.washington.edu/fhl/tidebites/Vol14/index.html.

The article is well-worth a read, and here's a video from it:

Update June 2014

Scientists are closer to having an answer to what's causing the mortality outbreak in sea stars. Drew Harvell of Cornell University and Friday Harbor Labs is working with a team that has traced the cause.

Read the latest article from KUOW's EarthFix team about the current status of the outbreak. There's also a terrific video on that page featuring Drew Harvell.

Sunflower Sea star (1)

Sea stars in various parts of the Salish Sea are experiencing a mass-mortality event. We're not sure of the cause, but we're working on it. (So are many other groups in the area.)

In October we looked for healthy and diseased sea stars during our dives for our new subtidal survey project. (See what else we found on those dives here.) During early November, we returned to two of the REEF monitoring sites from October where we saw the highest density of sea stars to see if sea star wasting disease has shown up since were were there last month. Fortunately we saw numerous sea stars and numerous species of sea stars and they all looked healthy. We will continue dives this weekend to look for more signs of disease.

Photos of diseased sea stars

Seastar expert Neil McDaniel, (www.seastarsofthepacificnorthwest.info) has graciously shared his photos showing the progression of the disease over a short period of a few weeks. This can give you an idea of what you're looking for. The before-and-after photos are pretty shocking. View the photos at Janna Nichols' SCUBA photo page.

Report sick and healthy sea stars

If you're a diver or a beach-walker and you see sea stars (healthy or diseased), report them at the Vancouver Aquarium's Sea Star Wasting Syndrome web page.

That page at the Vancouver Aquarium's website also has an overview of the outbreak.

Steller Sea Lions removed from Endangered Species List

David Ledig/U.S. Fish and Wildlife ServiceOctober 2013: NOAA Fisheries is removing the eastern Distinct Population Segment of Steller sea lions from the list of threatened species, because it has met its recovery criteria as outlined in the 2008 Steller Sea Lion Recovery Plan and no longer meets the definition of a threatened species under the Endangered Species Act (ESA). This makes the eastern population of Steller sea lions the first species NOAA has delisted due to recovery since 1994, when the eastern North Pacific gray whale was taken off the list of threatened and endangered species.

KUOW: Mass Starfish Die-Off May Be Headed For Washington

Evasterias-troschelii-sick.jpg

John Ryan of KUOW reported on the efforts in the United States and Canada to understand a starfish die-off.

“Every population has sick animals,” said SeaDoc Society wildlife veterinarian Joe Gaydos, on a boat off Orcas Island between research dives. “Are we just seeing sick animals because we’re looking for it, or is it an early sign of a large epidemic that may come through and wipe out a lot of animals?”

The timing of this news coincided with SeaDoc's first year of monitoring subtidal fish and invertebrates at 10 sites in the San Juan Islands. This project, done in conjunction with REEF and Friday Harbor Labs, is a multi-year study to track understudied populations in the Salish Sea. It's exactly the kind of effort that's needed if we're to have the right data to understand mortality events like these.

Gaydos cautions, "Despite the headline, we're not certain that a mortality event is heading into Washington State. During our 120 dives we saw many more healthy animals than sick ones. We collected samples and they will be tested microscopically and for infectious agents and a parasites."

Tracking changes in underwater fish and invertebrate populations

Tracking changes in underwater fish and invertebrate populations

This month, SeaDoc kicks off a project using trained citizen scientists to help study changes in subtidal fish and invertebrate populations. This ambitious multi-year intelligence-gathering effort will use recreational SCUBA divers -- trained and certified by the REEF Environmental Education Foundation as experts in identifying fish and invertebrates -- to get a long-term view of what's happening at multiple sites in the San Juan Islands.

Habitat protection proposed for endangered rockfish in Puget Sound
Kitsap Sun, August 6, 2013

Nearly 1,200 square miles of Puget Sound has been proposed as critical habitat for three endangered species of rockfish. Joe Gaydos is quoted as saying, "It is a joy to see [proposals like this] coming out because it means we are moving forward."

Harbor porpoises now a common sight in Puget Sound
Seattle Times, July 8, 2013

According to the SeaDoc Society’s Joe Gaydos, harbor porpoises are one of the few cetaceans that are a resident of the Salish Sea year round. A decline in gill-net fisheries and increased cleanup of industrial pollution may be a factor in their recovery. As the population has risen, so have strandings. “Is that just because the population is increasing?” Gaydos asks in the Times piece. “Or is there something else going on? If they are dying of something and we are missing it, that is really serious. And we don’t have enough data to tell us that.”

Experts sleuth out what killed Puget Sound orca
Huffington Post via Associated Press, April 12, 2012

"Joe Gaydos, a wildlife veterinarian with SeaDoc Society who has been working with a team of experts to understand what killed the whale, said they're considering all possible scenarios, including a strike from another animal, sonar activity, an explosion and other possibilities.

'Right now everything is on the table,' he said, adding that 'as scientists, we have to weigh all the evidence before we come to a conclusion.'

Gaydos and a team of biologists dissected the orca's head and examined the skull and brain during a necropsy last month. They found no fractures of the skull or jaw, indicating that the trauma or the force was dispersed over a larger area and not likely caused by a boat strike. They also found hemorrhaging and bleeding in the back of the orca's head.

'When something is shaken up, you'll have trauma at multiple locations,' Gaydos said."

Derelict Gear in California
San Jose Mercury News, Oct 31, 2011.

SeaDoc executive director Kirsten Gilardi was quoted in a Mercury News article about derelict fishing gear in Monterey Bay.

"We've seen a lot of beautiful rocky reef habitat covered in nets. They essentially smother the reefs," said veterinarian Kirsten Gilardi, associate director of the Wildlife Health Center at UC Davis. "They just drape over the reef like big bags," she said. "The kind of animals that are supposed to live there can't. The things that fish feed on can't grow. We've even found tires and old toilets dumped on a reef a couple of miles offshore off Malibu."  

In 2007 and 2008, UC Davis researchers removed more than 1 million feet of fishing line and thousands of hooks from the waters around 15 piers between Santa Cruz and Imperial Beach. They also left recycling containers for old plastic fishing line on the piers, but grants to do more cleanup work ran out.

So far, researchers have found that Monterey Bay contains far less debris than waters off Southern California and nearshore waters around piers. In Southern California and other places, the gear actually continues to catch fish, lobsters, crabs and other species, a practice known as "ghost fishing."

Species of Concern Almost Double

The 2011 Species of Concern paper written by Joe Gaydos and Nick Brown, and presented by Brown at the Salish Sea Ecosystem Conference, showed that the total number of species of concern has jumped from 64 in 2008 to 113 by January of 2011. The story was picked up by the Associated Press (by environmental reporter Phuong Le) and reprinted widely in outlets like the Seattle Times, Bellingham Herald, Kitsap Sun, several local television channels

Other publications on this topic include Meredith Griffin's piece in the Islands Sounder, and Curtis Cartier's piece in the Seattle Weekly, where he quoted Joe Gaydos: "Still, Gaydos says that economics is a crucial point to remember when thinking about the importance of species preservation. 'Wildlife watching employs about 21,000 people in Washington state,' he says, citing Washington Department of Fish and Wildlife numbers. 'That might not be more than Boeing, but it's more than Microsoft.'"

Born to be wild: Rehabbed and wild seal pups behave differently
Seattle Times, August 3, 2011

Lynda Mapes wrote about preliminary results from SeaDoc's tracking study of wild-weaned and rehabilitated harbor seal pups. 

"We were blown away," said Joe Gaydos of the SeaDoc Society, a non-profit research and conservation society based on Orcas Island. "It was pretty dramatic, we were amazed to see that those guys don't behave like wild seals."

"It is as if you had a group of people go out for a walk, and half of them go too far. Why?" Gaydos said. The researchers' hypothesis is that the rehab seals missed out on three or four weeks of instruction from their mothers, in which they would have leaned how to hunt by watching her, even though they would have still been nursing.

Puget Sound Partnership steadfast in science-based solutions to environmental threats
Kitsap Sun, February 5, 2011

Christopher Dunagan wrote about the Puget Sound Partnership and quoted Joe Gaydos extensively on the role of the Science Panel.

Since its inception, the partnership has struggled with what it means to restore Puget Sound to health by the year 2020 — a goal promoted by Gov. Chris Gregoire. Many people wanted the Science Panel to provide the answer.

But there is no single answer, said Joe Gaydos, a veterinarian with the SeaDoc Society who serves as vice chairman on the Science Panel.

"There are degrees of health, as it is with people," he said. "For some people, that means being able to run a four-hour marathon. For others, it means walking down and getting the mail. As scientists, we can tell you that if you want to run a four-hour marathon, you need to do this and this and this. If you want to get the mail, you have to do this."

A child may like killer whales and wish there would be 500 of them in Puget Sound, he said, but scientists can tell from the number of females and their reproductive capacity whether that is possible. Science can help identify factors, such as food and habitat, needed to reach ecological goals.

What will it take to restore salmon populations? What creatures would be helped by restoring an extra three miles of eelgrass or removing dams or dikes? Given budget limitations, the questions need to be carefully considered, Gaydos said, and that takes a partnership between scientists and policymakers.

Baby seals saved, returned to wild — then what? Scientists now track them
Seattle Times, October 25, 2010

Linda Mapes wrote about rehabilitation efforts for stranded and abandoned harbor seal pups, and the study, run by SeaDoc with funding from the National Marine Fisheries Service, that aims to find out whether rehabilitation efforts are successful. 

Joe Gaydos is quoted discussing the role that abandoned pups might play in the ecosystem. "They have big eyes and big whiskers, and they are cute," said Joe Gaydos, regional director and chief scientist for the SeaDoc Society, a nonprofit science and conservation group that is leading the study. Nobody, he noted, has much appreciation for the predators [the seal pup] might feed, if left to die on the beach. "We don't remember that they are supposed to feed some eagle's baby, or some crabs."

State board adds Salish Sea to region's watery lexicon

"It's an ecological victory," said Joe Gaydos, chief scientist for the SeaDoc Society, a nonprofit marine-science group that has used the name for years. "We talk about place-based conservation, but how do you do that without a name for the place or a sense of place? The border doesn't mean anything for the killer whales and the Pacific salmon that cross it every day."

The population information from Balcomb's annual census "has proved invaluable in understanding orca longevity and the effects of disease and toxic chemicals on the population, said Joe Gaydos, regional director of the SeaDoc Society. The census was the basis of an analysis that led to the listing of the killer whales as threatened under the Endangered Species Act. "Ken's life work has been scientifically rigorous and has fundamentally changed the way we think about killer whales and marine wildlife," Gaydos said. "He really epitomizes the intent of the award.""

Scientists Discuss Salmon Runs in Wake of Orca Deaths
Kitsap Sun, November 18, 2008

Christopher Dunagan covered the "strategic convening" moderated by Joe Gaydos to bring together fisheries and marine mammal biologists, oceanographers, toxicologists and behavior biologists to discuss the deaths of 7 killer whales in 2008.

"I think what surprised me the most," said Gaydos, "is that there are so many good things going on in the realm of salmon recovery." It was equally surprising to some, he said, to hear about the major efforts going into understanding killer whales and their vulnerabilities. It seems that the orcas do better when salmon runs are abundant, Gaydos said, but to say the animals starved to death is not yet supported by the data. "Vessel traffic and noise, contaminants and other factors are probably all playing a role," he said. Some salmon runs are up this year and some are down, Gaydos said. The big question is whether the fish are plentiful when the whales need them. For example, lactating females require more than twice the normal energy to feed their calves. One big question is whether the orcas are getting enough food in the winter when they spend more time in the Pacific Ocean. The animals range from British Columbia to California, but they could be using up their last energy reserves if they can't find enough food along the way. L pod, which seems to range farther than J or K pods, seems to be having the most trouble recently, Gaydos said.

Planning Could Save More Birds Caught in Oil Spills
Kitsap Sun, March 29, 2008

After the Nov 2007 Cosco Busan spill in San Francisco Bay, Washington State rushed to improve its planning for oil spill response. Christopher Dunagan quoted Joe Gaydos: "In San Francisco, they were prepared," said Joe Gaydos, a veterinarian and regional director of the SeaDoc Society on Orcas Island. "They have been working on this for many years, and it kind of brought the message home."

Grebe Experiment on Road to Success

Hide and Seek Seabirds

Hide and Seek Seabirds

Marine birds are important sentinel species for ecological conditions and to track them, scientists often count the birds at the breeding colonies, which tells us the number of adults trying to breed. But for seabirds that nest in burrows like Rhinoceros Auklets and Tufted Puffins, it's hard to know how big the colony is because the birds, eggs, and chicks can be 15 feet down underground.

Where have all the birds gone?

The last 30 years have seen precipitous declines in many of the bird species that visit the Salish Sea during the winter.

Bird Studies Canada seabird survey

Using various tools, private money and strategic collaborations, SeaDoc made a substantial investment to understand the problem of declining marine birds. We recently completed research demonstrating that diving birds that eat schooling forage fish are the species most likely to be in decline.

Tackling such a big issue is not easy. Understanding how we worked through this issue gives you a good idea of how SeaDoc can address what might seem to be insurmountable obstacles to healing the Salish Sea. It also shows you how private support makes our work possible.

Step 1: Identify the information gap

In 2005, SeaDoc brought researchers and managers from the US and Canada together to talk about the state of marine bird populations in the Salish Sea. It became clear that we were facing a big problem. Birds were declining in different jurisdictions, but it wasn’t clear how steep the declines were, which species were involved or what factors were behind these declines.

Because no one took a big-picture approach, bird restoration efforts were focused on one species at a time. But was there something going on at the ecosystem level causing multiple species to be declining?

We realized we needed an ecosystem-level look at which species were in decline and why.

Step 2. Get around transboundary roadblocks

Decades worth of data had been collected in Washington and British Columbia by the Washington Department of Fish and Wildlife (WDFW), Audubon, and Bird Studies Canada. But the organizations used different survey techniques and geographic scales so people had not been able to look at the data to get a perspective for the entire ecosystem.

SeaDoc was the ideal group to take on the challenge of merging these differing data sets from two different countries. State, provincial, and federal governments rarely have the time for this kind of effort. Also they have political constraints and pressures that make it hard to see past their borders.

Step 3. Hire a scientist to do the work

Collaborating with multiple groups, merging complex data sets and analyzing decades of data is a full time job for several years. Stephanie Wagner, a woman who loved the Salish Sea and its creatures, made a legacy gift to SeaDoc before she died. This gift provided the funding that allowed us to hire Dr. Nacho Vilchis to lead this important work.

Step 4. Use an epidemiological approach

Dr. Vilchis' first task was to get the data sets to “talk to each other.” WDFW conducts aerial transects from a plane. Bird Studies Canada and Audubon use point counts. Both are good techniques, but they produce surveys that are difficult to compare.

Nacho, who has a background in the statistical manipulations of large data sets, found a way to combine and use the three surveys in one overall analysis. Then he trimmed the set down to just 39 core species, removing the occasional visitors and the birds for which he didn’t have enough data to draw robust conclusions.

He also used GIS maps of the Salish Sea to connect each data point not only to a geographical area but also to major habitat characteristics, such as water depth.

Drawing heavily on the “Doc” part of SeaDoc, we used an epidemiological approach to find a likely diagnosis. Just as the family doc quizzes you for risk factors for diabetes or heart disease, SeaDoc found that two lifestyle factors among seabirds correlated to a very high risk of population decline.

Step 5. Translate results into recovery

The work, published in the internationally-acclaimed peer-reviewed journal Conservation Biology, showed that birds that dive to find food are much more likely (11 times as likely) to be in decline compared to non-divers.

But it’s worse if you’re a diver on a restricted fish diet. Diving birds that focus their efforts on small schooling fishes called forage fish were 16 times as likely to be in decline. Forage fish are small schooling fish that convert plankton into fat and are eaten by other fish, birds and mammals. These include herring, smelt, anchovies, eulachon, sardines, and sand lance.

But publishing a paper is not the end. It actually is just the beginning. This paper is now being used by scientists, managers and policy makers as evidence for the need to recover marine birds. Recovering forage fish will not just benefit birds, however. Because forage fish turn plankton into fat that’s available for other animals, they are a key part of the ecosystem and their recovery will benefit salmon, lingcod, rockfish, harbor porpoise and many other species within the Salish Sea.

Four key factors made this project successful.

1. Good data

Dr. Vilchis could not have conducted this analysis without scientists and citizens having already spent decades collecting rigorous data. The collection of these data took money, persistence, and forethought.

2. Collaboration

From the beginning, this project has been a story of collaboration. From the individuals collecting data over two decades to the senior scientists who worked out a way to share their data, it’s taken the work of many people working in different jurisdictions to make this happen. Our collaborators shared three huge datasets collected on two sides of an international border. They only did so because they were confident that SeaDoc would be able to use the data to produce robust scientific results.

3. Working on the level of the ecosystem, not the politics

This was the first study to look at bird declines across the entire Salish Sea marine ecosystem.

Most Canadian or US maps stop at the border, but the Salish Sea does not. Too often, the mandates and responsibilities of the people who work at the various state, provincial, and federal agencies tasked with keeping wildlife populations healthy also stop at the border.

SeaDoc, being privately supported by people like you who understand how important it is to treat the ecosystem as a whole, works across the entire ecosystem.

4. An extraordinary legacy gift

In the end, one person's financial gift made this project possible.

Without Stephanie Wagner’s legacy gift, this project would have been just a good idea that never got done. Instead, we made it someone’s job to find the truth that was hidden in the data.

Stephanie Wagner’s thoughtful gift enabled us to point clearly to a hidden problem affecting the productivity of the entire Salish Sea ecosystem. With her gift we were able to do good science that will make a difference in how scientists and managers work on healing the Salish Sea.

Put plainly, money can change the world for the better.

Please contact SeaDoc or your financial advisor if you’re interested in including SeaDoc in your will so you can leave a legacy for the health of the Salish Sea.

Alien Invaders: Invasive tunicates and shellfish aquaculture

While headlines about invasive tunicates have at times reached the breathless pitch of ads for campy horror films, there was legitimate concern because invasive tunicates in other regions of North America have severely impacted the aquaculture industry. Our Pacific Northwest shellfish industry annually pumps millions of dollars into the local economy. Introduced tunicates could potentially cause ecological and financial disaster.
