Earth Day on Saturday includes old events plus new March for Science

With Earth Day falling on a Saturday this year, all sorts of environmental activities have been scheduled for this weekend. On top of your typical Earth Day activities, there will be a March for Science in Washington, D.C., as well as in Seattle and hundreds of other communities across the country.

It just seems like a great time to get out and do something. I’m hoping the weather cooperates. The National Weather Service predicts that warm weather tomorrow will give way to a low-pressure trough moving over Western Washington on Saturday. That weather system might be traveling slowly enough that the rains won’t appear until later in the day when most activities have been wrapped up in the Puget Sound region.

I should mention that Saturday also is the annual Kids Fishing Party in Gorst, which coincides with the opening of trout season. Sponsored by the Kitsap Poggie Club, the family-fun event allows youngsters to catch a fish at the fish-rearing facility at Otto Jarstad Park in Gorst. Fishing rods and bait are provided, and the Poggies will even clean the fish for cooking. For details, go to the Poggie Club’s website.

New brochure alerts landowners to landslide hazards and what to do

Geology experts in Washington and Oregon have produced an easy-to-read brochure that can help people understand landslide risks, the underlying geology of slides and precautions that could avoid a disaster.

I have written a lot of words about landslides through the years, often relating stories of people involved in a catastrophic slope failures. But this new publication excels as a concise discussion of what people need to know if they live on or near a steep slope.

After the Oso landslide in the Stillaguamish Valley three years ago, I wrote a piece in the Kitsap Sun to help residents of the Kitsap Peninsula understand the risks they could be facing. Now I can point people to this graphically rich pamphlet, called “A Homeowners Guide to Landslides for Washington and Oregon” (PDF, 3.8 mb). It was produced by the Washington Department of Natural Resources and the Oregon Department of Geology and Mineral Industries.

“Our job is to understand Washington’s complex geology and how it impacts the people who live here,” Washington State Geologist Dave Norman said in a news release. “We want to make sure we put that information into their hands.”

Puget Sound and other estuaries are facing the federal chopping block

Federal funding to restore Puget Sound and other large U.S. estuaries would be slashed by more than 90 percent under a preliminary budget proposal coming from President Trump’s administration.

Funding for Puget Sound restoration would be cut by 93 percent, from the current budget of $28 million to just $2 million, according to figures cited by the Portland Oregonian and apparently circulated by the National Association of Clean Air Agencies. Here’s the list.

The Great Lakes, which received a big boost in spending to $300 million in the current biennium, would be hammered down to $10 million. Chesapeake Bay, currently at $73 million, would be reduced to $5 million.

Much of this money goes for habitat protection and restoration, the kind of effort that seems to be kicked to the bottom of the priority list, at least in these early budget figures. The new EPA administrator, Scott Pruitt, appears to be focusing on upgrading water infrastructure, cleaning up toxic sites and reducing air and water pollution, although everything is cut deeply and details remain murky.

Thoughts run to an orca called Granny and her clan of five generations

Looking back on the various comments that followed the death of the killer whale named Granny, I realized that there were a couple of thought-provoking tributes that I never shared with readers of this blog.

Granny, designated J-2, was believed to be more than 100 years old, and she was the obvious leader for many of the Southern Resident orcas that frequent Puget Sound. Granny went missing last fall and was reported deceased at the end of the year by the Center for Whale Research. See Water Ways, Dec. 30.

Some tributes to Granny were written and posted soon after her death notice, including one by Ken Balcomb of the Center for Whale Research. I posted my thoughts along with some others in Water Ways on Jan. 4.

Amusing Monday: Entertaining videos don’t show real holograms

An amusing video that shows a young family experiencing close-up encounters with killer whales, a polar bear and several penguins has been making the rounds on social media. The technology has been described as a hologram by many people posting and reposting the video, the first on this page.

Frankly, I was amazed at first, believing that people were really up close and personal with a 3D image in a shopping mall. The animals, which I assumed were projected for all to see, appeared so real that it was no wonder that people in the video were reaching out to touch them. Unfortunately, that’s not what we are seeing, according to observers.

Crab Team training will foster the upcoming hunt for green crab invaders

A European green crab invasion may be taking place in Puget Sound, and Washington Sea Grant intends to enhance its Crab Team this summer with more volunteers looking in more places than ever before.

The second European green crab identified in Puget Sound was found in Padilla Bay, where three others were later trapped.

Training is about to get underway, and anyone with an interest in furthering science while being exposed to the wonders of nature may participate. It’s not always good weather, but I’ve been inspired by the camaraderie I’ve witnessed among dedicated volunteers.

The work involves going out to one or more selected sites each month from April into September with a team of two to four other volunteers. It is helpful to have folks who can carry the crab traps, plastic bins and other equipment. For details, check out the Washington Sea Grant website.

Seals and sea lions may be undercutting chinook and orca populations

Seals and sea lions can no longer be ignored in the effort to recover our threatened Puget Sound chinook salmon or our endangered killer whales.

A new study shows that seals and sea lions are eating about 1.4 million pounds of Puget Sound chinook each year — about nine times more than they were eating in 1970, according to the report. Please read the story I wrote for the Encyclopedia of Puget Sound, also published in an abridged version in the Kitsap Sun.

Seals and sea lions in Puget Sound get the first chance to catch the chinook as they leave the streams and head out to the ocean. Since they are eaten at a very young age, these small chinook, called “smolts,” never grow into adults; they never become available for killer whales or humans.

Based on rough estimates, as many as one in five of these young fish are getting eaten on their way out of Puget Sound. If they were to survive the seals and sea lions and one factors in the remaining mortality rate, these fish could translate into an average of 162,000 adult chinook each year. That’s twice the number eaten by killer whales and roughly six times as many as caught in Puget Sound by tribal, commercial and recreational fishers combined, according to the study.

Amusing Monday: Playing with water in the weightlessness of space

Since the beginning of the manned space program, astronauts have been playing with water in microgravity conditions. The result has been a large assortment of videos demonstrating the unique and amusing properties of water.

In the first video on this page, Chris Hadfield, an astronaut with the Canadian Space Agency demonstrates what happens aboard the International Space Station when you ring out a soaked wash cloth in the weightlessness of space.

The experiment was suggested by students Kendra Lemke and Meredith Faulkner of Lockview High School in Fall River, Nova Scotia. It was posted on YouTube in 2013.

The video shows that the surface tension of water is great enough that the water keeps clinging when Hadfield rings out the cloth. If you watch closely, however, you can see a few droplets fly off when he starts to ring out the cloth.

Invasive oyster drills react differently to predators than natives

Invasive saltwater snails, including dreaded oyster drills, seem to be far more leery of predators than native snails under certain conditions, according to a new study by Emily Grason, whose research earned her a doctoral degree from the University of Washington.

Why non-native snails in Puget Sound would run and hide while native species stand their ground remains an open question, but the difference in behavior might provide an opportunity to better control the invasive species.

Of course, snails don’t actually run, but I was surprised to learn that they can move quite rapidly to find hiding places when they believe they are under attack.

Like many marine animals, snails use chemical clues to figure out what is happening in their environment. For her experiments, Emily created a flow-through system with two plastic shoeboxes. Chemical clues were provided in the upstream bin, while the reaction of the snails was observed in the downstream bin.

The most dramatic difference between native and non-native snails seemed to be when ground-up snails were deposited in the upstream bin, simulating a chemical release caused by a crab or other predator breaking open snail shells and consuming the tender morsels inside.

Federal Action Plan for Puget Sound released as Trump enters office

Two days before Donald Trump became president, the Puget Sound Federal Task Force released a draft of the federal action plan for the recovery of Puget Sound.

The Trump transition raises uncertainty about the future of this plan, but at least the incoming administration has a document to work with, as described by Steve Kopecky of the White House Council on Environmental Quality. (See Water Ways, Dec. 22.)

Speaking last month before the Puget Sound Partnership’s Leadership Council, Kopecky acknowledged that the plan would go through many changes over time, with or without a new president.

“That being said, the first one is probably the most powerful,” he said. “It is the model that new folks are going to use, so we’re trying to make sure that we have a good solid foundation model before we all collectively go out the door.”
