Watching Our Water Ways

J pod typically passes through the area throughout the winter months. It is K and L pods that spend more time in the open ocean along the West Coast. Until yesterday, J pod had been gone for more than 70 days, according to Capt. Jim Maya of Maya’s Westside Charters.

Orca Network received reports that J pod was off Victoria around noon. The pod moved east and then north along San Juan Island, shuffling along the west side between Lime Kiln State Park and Henry Island all afternoon. They were last seen heading north up Haro Strait.

Ken Balcomb of the Center for Whale Research reported that all the members of J pod were accounted for and no animals had died through the winter, which is cause for celebration. (See Orca Network’s Facebook page.) It appeared no babies had been born either. The last J pod calf was J-49, first spotted in August of last year.

K and L pods should begin to make their appearances in the inland waters in the near future. Whether they stick around probably depends on how many salmon they encounter. Typically, these Southern Resident orcas begin to roam around the San Juans and lower Strait of Georgia in early to mid-June, as chinook salmon return to rivers in the region.

When it comes to cleaning up bacterial pollution in Puget Sound, we seem to have a clash — or at least some redundancy — in the methods we use.

Sailors take advantage of nice weather last week on Liberty Bay.

In Kitsap County, water-quality officials are saying studies conducted by the Washington Department of Ecology, which allocated total maximum daily loads (TMDLs), have not been much help in attacking the local pollution problem.

That’s because the approach developed by Kitsap County, called the Pollution Identification and Correction (PIC) Program, has been highly successful in tracking down and cleaning up bacterial pollution.

I wrote a story about this issue as it relates to Liberty Bay in yesterday’s Kitsap Sun.

I also talked a little about the two water-quality standards used for streams. It’s somewhat odd how Liberty Bay must conform to a stricter standard than nearby Dyes Inlet, since both are in urbanizing areas. By the way, there is only one standard for marine waters, and Liberty Bay is generally clean under that standard.

Other information on the Liberty Bay TMDL study can be found on Ecology’s website and in a news release.

With regard to cleanup methods, now that PIC has been adopted and funded for the Puget Sound region, one might argue that it is time to back away from the more cumbersome TMDL approach, which spends a great deal of money to allocate pollution loads with no guarantees that any cleanup will get done. For recent funding details, review the Washington Department of Health’s Page on “EPA Grant: Pathogens, Prevention, Reduction and Control” and the specific funding for PIC projects.

Although I’ve heard the PIC approach being widely touted, I’m not sure state and federal water-quality officials are entirely sold on the approach, especially when funding is an issue, as it is in many counties. Kitsap County funds an extensive monitoring program through its Surface and Stormwater Management Fund. Each resident in unincorporated areas of the county pays an annual fee to support water-quality efforts.

One thing local water-quality officials have learned through the years is that pollution is a never-ending problem. Once a waterway is cleaned up, ongoing monitoring provides an early warning for new problems that show up.

A lot of bureaucracy has built up around the federal Clean Water Act and its approach to pollution problems, including the TMDL studies. The Environmental Protection Agency — and by extension Ecology — are under an out-of-court settlement to complete TMDL studies for all impaired water bodies.

Conditions of the settlement, which might complicate a shift away from the TMDL approach, are under renegotiation. It might be time for all the parties to focus a little more on the cleanup efforts and less on the studies themselves. I have no doubt that everyone wants cleaner water, but there is a lingering concern that changing the rules could have unintended consequences.

The Washington Department of Ecology has started to wade into this issue by placing some impaired streams on a 4b list, where they sidestep the TMDL process while undergoing cleanup. To meet the criteria, the local government must demonstrate an effective method of reducing pollution, a time schedule for completion and a long-term monitoring program, among other requirements.

A good explanation of this process is provided in a report by Helen Bresler with Ecology and Laurie Mann and Eric Monschein, both with EPA. See “Category 4b Demonstration for Pathogen Impaired Tributaries to Puget Sound in Kitsap County, Washington” (PDF 57 kb), which states:

“In Kitsap County, Ecology observed (that) progress towards achieving water quality standards was being made quickly, and decided that expending additional resources on TMDL development may slow down the work that was already underway. Once Ecology decided to support placing the Kitsap watersheds into Category 4b, Ecology worked closely with Kitsap Health District staff to develop the 4b rationale required by EPA…

“In Washington, Ecology does not use Category 4b as an up-front ‘tool’ to improve water quality. Rather, 4b listings document active efforts to get to clean water that Washington believes will be successful without a TMDL…. Because Washington sets a fairly high bar for putting waters into Category 4b, Washington is sometimes in a position of telling a group that Category 4b is not appropriate because one or more of the 4b requirements cannot be met with their efforts.”

For some reason, not all of the streams in Liberty Bay were placed on the 4b list, and we ended up with a $600,000 report that Kitsap officials say is not of much help in their cleanup effort.

Perhaps if more counties take note of this outcome, they will choose to develop complete, locally funded monitoring programs and attack the pollution at its source. The result could be fewer elaborate studies and more rapid cleanup. As I noted in yesterday’s story, several local counties already are taking the first steps in this direction.

When I hear about research taking place in Earth’s polar regions, I often wonder how our amazing ice-breaker ships make it through the ice. Do they just plow forward without hesitation, or do they worry about getting stuck?

Cassandra Brooks, a doctoral student at Stanford University, recently compiled an intriguing video showing time-lapse scenes of the Nathaniel B. Palmer on a cruise just completed in the Ross Sea of the Antarctic.

Cassandra’s narration provides a clear explanation of all kinds of ice encountered by the ice breaker, and she touches on the research itself.

“It was so beautiful,” Brooks told NBC News’ LiveScience. “And it was such a neat experience to be on this crazy boat that was just screaming through the ice.”

The video was part of a blogging project she undertook for National Geographic. The blog includes just seven entries, but each is an enjoyable science lesson for the reader. Take the entries in chronological order (bottom first) to get the full story of the adventure.

Before entering the Emmett Interdisciplinary Program in Environment and Resources, Brooks worked in both basic research and environmental education, according to the bio she wrote for her own website.

She holds a graduate certificate in science communication from the University of California, Santa Cruz, and has published articles for both scientific and general audiences.

Casandra informs me that she hopes to write a final closing blog related to the recent cruise and will probably continue blogging about other projects.

When my editor, Kim Rubenstein, asked me to write a story for people who wish to check out the Elwha River restoration, it seemed like a good idea. After playing the role of tourist for a day, I’m convinced that many visitors will have a good time learning about this once-in-a-lifetime event.

I wrote a story for Sunday’s Kitsap Sun that describes where you can go to see the river and various features of the restoration project. The area map we created for the newspaper can be downloaded and taken with you. Click here for map (PDF 438 kb).

Learning about the natural features of the Elwha River watershed is an important part of the experience. Before you leave home, I recommend that you view a series of “webisodes” on the Olympic National Park website. I’m told these videos by Wings Over Watersheds are a sampling of what will eventually become a longer video production.

A more complete story about the Elwha Restoration Project, including a history of the two dams, has been captured in a new book by Seattle Times reporter Linda Mapes. I wrote a review of her book, “Elwha: A River Reborn,” to accompany my visitor’s guide to the area.

I think kids and adults alike will enjoy playing around with a model of Glines Canyon at Feiro Marine Life Center, where one can pull out the dam and watch the sediment move downstream.

Randall Walz, director of education and volunteers at the center, told me about misconceptions that some people have. Many believe that the sediment in the Elwha moved downstream and piled up behind the dams, he said. Instead, most of the sediment was dropped off in the upper portion of the two reservoirs, where the water slowed down as it entered the lakes.

The restoration work included digging a pilot channel through the Lake Mills delta to form a new channel and guide the river through the trapped sediment. The goal is not to move the sediment downstream as quickly as possible, Walz said, but rather to stabilize the deltas and allow them to erode over a longer period of time.

If you want to see change, be sure to visit the mouth of the Elwha River, which you reach from a dike trail at the end of Place Road. Wherever you see sand, that’s change, because there was no sand here before, said Anne Shaffer of the Coastal Watershed Institute.

The sandy habitat will better support the migration of juvenile salmon and provide spawning areas for sandlance, a forage fish. The decline of the rocky habitat could mean the end of tall kelp, but researchers hope the new sandy habitat will support the growth of eelgrass and a burgeoning community of diverse plants and animals. Check out the story I wrote in March, following a conference on the nearshore changes taking place.

I have to say there’s not a lot of excitement to behold in the upper portions of the two reservoirs unless you remember what it was like when the lakes were in place or can visualize the enormity of the change. The river now carves its way through a dry lake bed, where one can see large old-growth stumps, which were either under water or buried by sediment. Plants are coming back, some placed there by restoration workers, others by natural processes.

With or without the dams, one can enjoy the escape into this natural area, particularly as one moves into the higher trails in Olympic National Park. Be sure to take time to enjoy the natural surroundings, even if you need to cut out parts of your planned trip.

If you want to observe the changes over time, I suggest you find a vantage point and take a picture during your visit. When you return the next time, take another picture for comparison. The heavy gravel and silt seems fairly inhospitable at the moment. But if you return again and again, I expect you’ll be amazed at the transformation taking place over the next few years.

Lolita, a killer whale taken from Puget Sound in 1970 and placed in a Miami aquarium, could be reclassified as an endangered species, along with other endangered Southern Resident orcas. At the moment, Lolita is not listed at all.

NOAA Fisheries announced today that PETA — People for the Ethical Treatment of Animals — has provided adequate documentation to consider whether captive orcas (specifically Lolita) should be listed along with their counterparts still roaming free.

One must not presume, however, that because NOAA has accepted PETA’s petition that a listing will follow, agency officials stressed.

I was under the impression, from talking to NOAA officials last year, that we would soon know whether or not the entire Southern Resident population would be taken off the Endangered Species List, as proposed by Pacific Legal Foundation. But that decision appears to be delayed for consideration of the Lolita petition.

“The agency said to make sure that its review is complete and based on the best available science it would now solicit any new information about Lolita’s genetic heritage and status to include in the ongoing status review,” NOAA said in a news release. “A finding on the delisting petition is due next January.”

PETA filed its petition on behalf of the Animal Legal Defense Fund, Orca Network and four individuals. The 33-page petition, filed in January, applies only to Lolita, since the 35 other killer whales captured in Puget Sound have died, the petition notes. Documents — including the Lolita petition — can be found on NOAA Fisheries’ website. I discussed PLF’s delisting petition and provided links to related documents in Water Ways last Oct. 24.

The PETA petition strongly challenges the reasons for ever leaving Lolita out of the endangered population:

“No explanation was offered for Lolita’s exclusion from the listing because no legitimate explanation exists. Lolita’s biological heritage is undisputed. The Endangered Species Act unquestionably applies to captive members of a species, and the wholesale exclusion of captive members of a listed species is in excess of the agency’s authority.

“Lolita’s exclusion serves only one purpose: It protects the commercial interests of the Miami Seaquarium. The Endangered Species Act specifically precludes agency consideration of whether listing a species would cause the holder of any member of the species any economic harm. Thus Lolita’s exclusion violates the act.

“This petition urges the National Marine Fisheries Service to rectify this unjustified and illegal exclusion, thereby extending Endangered Species Act protections to all members of the Southern Resident killer whale population.

“Although as a legal matter Lolita’s genetic heritage is sufficient to merit her listing, this petition provides additional support in four sections. The first section provides the factual background regarding the Southern Resident killer whales’ listing and Lolita’s exclusion. The second section explains the application of the act to captive members of listed species. The third section applies the five factors that govern listing decisions under the act to the Southern Resident killer whales generally and also to Lolita. The fourth section considers policy reasons that support Lolita’s protection, given her significant scientific value to the wild population.”

Today is Earth Day and a good time to consider the Earth as a whole. Thanks to an impressive set of videos released by NASA in celebration of Earth Month, we can take a wide-angle view of the entire planet.

The first video serves to demonstrate the many images generated by NASA’s fleet of science satellites and aircraft. The space agency chose to accompany the video with music rather than narration, which ties together the images better than a detailed description. To delve more deeply into the science behind the images, visit NASA’s “Missions” page.

The second video shows the beauty of the Earth as seen from the International Space Station. The third is a blend of Earth images, computer animations and glimpses of the science behind it all. Although these videos are not amusing in a humorous way, I hope you’ll find them worth a look on Earth Day.

If you would like more NASA videos, still images and explanations, check out NASA’s “Earth Month 2013.”

The Pacific Fishery Management Council decided yesterday that it was time to consider, within its management plans, how large-scale fishing at certain times and places can create ripple effects in the food web.

The council adopted a new Fishery Ecosystem Plan to help manage West Coast fisheries, broadening the view of how fishing can shape the entire ocean community.

“It’s the beginning of a paradigm shift in fisheries management,” Paul Shively of Pew Charitable Trusts told Jeff Barnard, environmental reporter for the Associated Press.

In the past, managers have tried to figure out what level of fishing can be sustainable. Now, in theory, they will also consider how a reduction in the numbers of certain fish can affect marine creatures that might want to eat them or be eaten by them.

“We’ve always managed our oceans on a species-by-species level,” Shively noted. “By developing an ecosystem plan we begin to look at how everything is connected in the ocean.”

Dan Wolford, chairman of the Pacific Fishery Management Council, offered this observation in a news release (PDF 119 kb) from PFMC:

“We now enter into a new era of more sophisticated fishery management. We heard strong public testimony calling for more protection for unmanaged forage fish, and the council’s adoption of this motion today formalizes the council taking this up this as a fishery management action.”

Jane Lubchenco, former director of the National Oceanic and Atmospheric Administration, said the agency has been talking about the ecosystem-based approach since the 2006 renewal of the Magnuson-Stevens Fishery Conservation and Management Act.

“Taking an ecosystem approach to fisheries management is widely viewed as an enlightened approach to fishery management, because it recognizes that the target species of interest exists within a broader ecosystem,” she said in Barnard’s piece. She is now a visiting professor at Stanford University,

The Fishery Ecosystem Plan does not replace existing management plans, including those for salmon, groundfish, highly migratory species or coastal pelagic species. But it does call for the consideration of more factors before making management decisions, and it mandates an annual “State of the Ecosystem” report.

One initiative connected to the plan calls for the prohibition of targeted fishing for unmanaged forage fish until the impacts are better known. Eight other initiatives will discuss how harvest affects stocks, bycatch, habitat, fisheries safety, fisheries jobs, response to climate change, socioeconomics, and other factors.

For extra reading: I found the discussions about managing krill in the Antarctic to be revealing. See “License to Krill: A Story About Ecosystem-Based Management” on NOAA’s website. It includes this tidbit:

“When fishing reduces the population of one species, there are ripple effects throughout the marine food chain. For instance, if the human species takes more krill out of the ecosystem, the populations of other animals that prey on krill might decline.

“But it’s not just a question of how much krill we take. Where and when we take it are also important. Penguin chicks need to find food when they fledge at the end of their first summer. For certain species of seals, which carry their pregnancies through winter, wintertime forage is critical. By identifying where and when these critical periods occur, scientists can advise fishery managers on how best to reduce the impacts of fishing on the other species we care about.”

I discussed the ecosystem plan briefly in the latest installment of a series of stories dealing with Puget Sound’s ecosystem and indicators chosen by the Puget Sound Partnership. We call it “Taking the Pulse of Puget Sound.”

A research project that involved tracking the travels of K pod for more than three months in the Pacific Ocean apparently has ended, as the transmitter seems to have run out of battery power, according to research biologist Brad Hanson.

“This has been a phenomenal deployment,” Brad told me yesterday after it appeared he had logged the final transmission from K-25. “It has been a quantum leap forward for us in terms of understanding what is going on.”

K-25 is a 22-year-old male orca who was implanted with a satellite tag on Dec. 29. The battery was expected to last for 32,000 transmissions, and it actually reached about 35,000, said Hanson of NOAA’s Northwest Fisheries Science Center. No data arrived yesterday during the normal transmission period.

The three months of satellite tracking data will be combined with fecal and prey samples from a 10-day research cruise to serve up a wealth of information about where the Southern Resident killer whales go and what they eat during the early part of the year, Brad said. Until now, this has been a major blank spot in the understanding of these whales, he noted.

The information gathered over the past three months should prove valuable in management efforts to protect and restore these orcas, which are familiar to human residents of the Puget Sound region. After the data are analyzed, federal officials should be able to say whether they have enough information to expand “critical habitat” into coastal areas for the endangered killer whales. If not, we should know what additional information may be required.

Brad says he feels a high level of anticipation from his fellow killer whale experts who are eager to learn of the research findings, especially the results of what the whales are eating.

“We have a tremendous amount of data, and we’re trying to push it through as quickly as we can,” he said.

Brad says he won’t release the findings until the analysis is further along. But he did dangle this intriguing tidbit in front of me: The whales are NOT eating chinook salmon exclusively.

The tracking project has another benefit, Hanson said. It will bring new meaning to more than three years of acoustic data (recorded sounds) picked up by hydrophones dispersed along the Washington Coast. Until now, it was not possible to determine the locations of the whales from their sounds alone, because the sounds could be picked up from many miles away. Now, thanks to tracking data, the intensities of their calls and echolocation clicks can be correlated with distance to a greater extent. Researchers are developing a computer model to identify possible locations from as much as seven years of hydrophone data in some places.

The tracking project began on Dec. 29, when K-25, named Scoter, was darted with a satellite tag near Southworth in Kitsap County. K-25 and presumably the rest of K pod then moved out into the ocean. Check out the tracks on NOAA’s satellite tagging website.

“We were extremely lucky to get that tag at the end of the season,” Hanson said.

It was K pod’s last trip into Puget Sound for several months, he noted, and it is a real challenge to get close enough to dart a killer whale, especially when only certain ones are candidates for the tag.

By Jan. 13, the whales had reached Northern California, where they continued south, then turned around at Point Reyes north of San Francisco Bay. They continued to wander up and down the West Coast, including Northern California, into early March. After that, they began to stay mainly off the Washington Coast with trips into northern Oregon. They seemed to focus much of their attention near the Columbia River, where early runs of salmon may be mingling.

The research cruise, originally scheduled for three weeks, ran from March 1 to March 10, cut short by the federal budget sequestration. By following the whales, researchers were able to collect 24 samples of prey (scales and/or tissues of fish) plus 21 fecal samples from the whales themselves. Shortly before the cruise, K pod met up with L pod, probably off the Washington Coast.

The ability to track the whales and the fortune of decent weather were major factors in the success of the research cruise, Brad said. In contrast, several previous cruises had netted only two prey samples and no fecal samples.

“We are ecstatic about the amount of data we collected in such a short period of time,” Brad told me. “If we would have had 21 days instead of 10, just think what we could have done.”

Tagging the whales with a dart, which penetrates the skin, has been controversial among whale observers. Some contend that we already know that the whales spend time in the Pacific Ocean, and maybe that’s enough.

But Brad says many detailed findings from the past three months were never known before — such as how much time the whales spend off the continental shelf and how much time they spend in and around canyons at the edge of the shelf.

The sampling of fish scales and fish tissues should reveal not only the species of fish, but also specific stocks of salmon as well as their age, Brad said.

“Are they actually targeting the larger and older fish?” he wondered. “Some fish are resident on the continental shelf. Are they targeting those? Are they going after the ones they can easily detect, which means not going after the smaller fish?”

The cruise also collected all kinds of information about the ecosystem, ranging from ocean depths to zooplankton to the kinds of birds seen in the area. All that information will feed into a description of the essential habitat the whales need during their winter travels.

During the cruise, another whale, L-88, a 20-year-old male named Wave Walker, was tagged as an “insurance policy” to allow the whales to be tracked if K-25′s transmitter failed. A shorter dart was used on L-88, and the tag apparently fell off about a week later.

The ocean environment is very different from Puget Sound, where the habits of the whales are well known, Brad explained. In the San Juan Islands, groups of whales are rarely far apart compared to the scale of the ocean, he noted.

In the ocean, the orcas were generally grouped up during resting periods. Sometimes Ks and Ls were together; other times they were apart. When they were foraging, however, the individual animals might be spread out for miles.

Brad said he expects to put the new information into some kind of agency report, probably followed by a peer-reviewed journal article.

“We have put a lot of time and effort to get to this point,” he said, adding that the researchers feel a sense of accomplishment now that the effort has paid off.

I just completed the second part of a yearlong series I’m writing about the Puget Sound ecosystem and the 21 “vital signs” indicators chosen by the Puget Sound Partnership to measure the health of the sound.

This second part, published in Sunday’s Kitsap Sun, consists of stories about the food web, including plankton and eelgrass; forage fish, including herring; and bulkheads, which are generally considered a threat to the nearshore ecosystem.

I was trying to cover the lower half of the food web, to build a foundation for the other parts to come.

I talked to a lot of experts on these issues and ended up writing one of the largest story packages I’ve ever written. Still, I barely touched the surface of these topics. I guess I’ll have to return later to dig a little deeper.

Scientists often say, the more they know, the more they realize what little they know, or something like that. I’ve always tried to help people understand the complexities of environmental science, but there are no simple answers.

That’s why the Puget Sound Partnership is an important bridge between policymakers and scientists. We have enough tools to know what should be done to save Puget Sound, but how do we know what projects should come before others? What can we afford to do? And how do we measure success or failure? Those are the questions challenging the partnership at the moment.

I would like to thank all the researchers willing to give their time to this project as well as Kitsap Sun staffers who helped crunch the numbers and produce the graphics for the story package, as well as the editors who offered ideas along the way.

The overall series is called “Taking the Pulse of Puget Sound.”

A research team led by Brad Hanson of NOAA’s Northwest Fisheries Science Center has been tracking K and L pods off the coast of Oregon and California, most recently offshore of Washington’s Willapa Bay.

Satellite transmissions from two killer whales, K-25 and L-88, show their pods crossing the Columbia River this morning.
Map by Robin Baird with NOAA data

The team left Newport, Ore., on Friday aboard the 209-foot research vessel Bell M. Shimada. The crew caught up with K pod the following day with the help of a satellite transmitter attached to K-25, according to reports. Most if not all of L pod was seen swimming with the K pod whales near Cape Blanco, off the southern coast of Oregon.

The research team attached a new satellite tag to L-88, a 20-year-old male named Wave Walker. The new tag will provide another method of following the whales if the tag attached to K-25 should fall off, as expected sooner or later. It has already stayed attached for more than two months, about twice the average life of the satellite tags.

I have not yet connected with Brad Hanson, but I talked to Robin Baird of Cascadia Research, who has been getting reports from the crew. Robin told me that the researchers have been able to obtain multiple fecal and/or fish-scale samples on most of the days they have been at sea.

Those samples will aid in meeting the primary goal of the cruise, which is to figure out where the whales are going and what they are eating during the winter months while away from Puget Sound.

The satellite tags have allowed the research ship to stay with the whales even when the weather and their lack of vocalizations have made them hard to find, Robin said. As a result, this research cruise has been more efficient than past ones in terms of both time and fuel.

The research trip, which was scheduled for 21 days, will be cut in half because of the federal spending cuts related to the sequester, according to a statement issued by this afternoon by the Northwest Fisheries Science Center.

The travels of K-25 over the past two months are shown in an animation produced by staff at Northwest Fisheries Science Center. (In my browser, the north and sound portions of the map are cut off even in full-screen view, but the movements shown are still amazing.)

The latest report shows both tagged whales swimming offshore of Willapa Bay on the Washington Coast, having crossed the Columbia River mouth this morning. The full trip can be viewed on maps posted on the website called Southern Resident Killer Whale Satellite Tagging.
