Earth Day events go online because of virus

Share

Canceled! Canceled! Canceled! Participants in this year’s Earth Day activities won’t be rallying in large groups, participating in environmental festivals or coming together to clean up the Earth. On the 50th anniversary of Earth Day — Wednesday of next week — the environmental movement will be uniquely digital, with many people celebrating from their home computers. Before the COVID-19 pandemic took hold, this year’s Earth Day was being promoted as the “largest environmental mobilization in history,” as Forbes magazine trumpeted in a headline. Millions of people were being mobilized. Now […]

Salmon expeditions challenge old beliefs

Share

Long-held assumptions about where salmon go during their years of swimming in the Pacific Ocean may need to be revised, according to Dick Beamish, a Canadian salmon researcher who helped organize two scientific expeditions into the Pacific Ocean. For example, sockeye salmon have been caught in nets farther south than conventional wisdom would suggest, Beamish said, while fishing was hit-and-miss in the same area at different times, suggesting that pink and chum salmon were schooling more than expected. The second International Gulf of Alaska Salmon Expedition ended Tuesday after nearly […]

Time to spare? Why not conduct some real online research to advance science

Share

If you are looking for something constructive to do in this stay-at-home period of our lives, I might suggest joining a team of scientists conducting real online research. Zooniverse, a clearinghouse of about 100 active crowd-sourced science projects, has added educational materials for all age groups. Students learning at home can assist professional researchers as they seek answers to real scientific questions. For a few other stay-at-home ideas, skip to the bottom of this page. One interesting Zooniverse project is “Penguin Watch,” in which citizen scientists are asked to look […]

Sewer operators worry that toilet paper shortage will lead to more nasty clogs

Share

With a multitude of people scrambling to buy toilet paper, and some going without, sewer utility officials across the country are worried about the possible repercussions of the TP shortage — such as clogged sewer lines. Toilet paper and wipes of all kinds have become the subject of a complex, wide-ranging and controversial debate. The issue was even argued this year in the Washington Legislature. But for hard-working public employees who clean out the sewers, the bottom line is simple: DON’T FLUSH ANYTHING BUT TOILET PAPER (unless it’s human waste, […]

Second Pacific salmon expedition gets a chance to see the effects of cooler water

Share

A second research cruise to study the winter travels of salmon in the Pacific Ocean got underway today, when 12 scientists from three countries left Victoria, B.C., aboard the trawler Pacific Legacy. Researchers say they have learned a great deal from the first salmon cruise a year ago, when 21 scientists from five countries ventured out into the Pacific to take samples of fish and other marine life. The samples are being shared with dozens of biologists trying to piece together the complex food web that supports five species of […]

Virus related to measles could push Puget Sound orcas to extinction, study says

Share

Researchers studying the killer whales that frequent Puget Sound are growing increasingly concerned that a dangerous virus or other disease-causing organism could spread through the population and hasten extinction of these critically endangered southern resident orcas. Without dramatic changes to their environment, extinction is already considered the likely future for the southern residents, as they continue to face shortages of food, high levels of chemical contamination and stress from the noise around them. Their numbers have declined from 98 animals in 1995 to 72 today. New research suggests that extinction […]

Harvest managers setting this year’s salmon seasons struggle to find ways to help orcas

Share

As state, tribal and federal salmon managers work together to establish this year’s fishing seasons, they have not forgotten about the needs of Puget Sound’s endangered killer whales. In fact, new documents related to the southern resident orcas describe an investigation looking to find ways to reduce fisheries at certain times and locations that might get the whales more food. And yet it appears that nobody has figured out a way to help the whales by reducing salmon fishing. Annual negotiations to establish seasons and quotas for commercial, tribal and […]

Shoreline armoring in Puget Sound gets new scrutiny from the Army Corps of Engineers

Share

Shoreline bulkheads, which can damage beaches and destroy fish habitat, could come under more extensive review and permitting as the result of a revised shoreline policy announced last week by the U.S. Army Corps of Engineers. The revised policy (PDF 163 kb), which resulted from a federal lawsuit, now requires a Corps of Engineers permit for shoreline construction below the high-tide line. The previous line of jurisdiction was lower on the beach, effectively exempting most shoreline armoring from federal permits. One of the key results of the policy change is […]

New fishing rules increase limits on warm-water fish to indirectly help orcas

Share

In an effort to protect young salmon from predation, new fishing rules will allow anglers to double their catch of some warm-water predatory fish found in 77 lakes across Washington state. Reducing the population of salmon-eating bass, catfish and walleye is one of many ideas promoted by the governor’s Southern Resident Orca Task Force, which considered various strategies for increasing the number of Chinook salmon. Declining numbers of Chinook — a primary prey of the endangered orcas — is considered a leading cause of the dwindling population of southern resident […]

New report describes anticipated climate-change effects in Washington state

Share

Early effects of a warming Earth have reached Washington state, as we can see from actual measurements. Annual snowpack is declining in the mountains; ancient glaciers are shrinking; sea levels are rising; and coastal waters are becoming less hospitable to sea life. These are some of the changes outlined in a new easy-to-read briefing report titled “Shifting Snowlines and Shorelines” by the Climate Impacts Group at the University of Washington. The report is designed to bring a clear message to leaders and citizens of Washington state regarding where we have […]

Missing orca named ‘Mega’ lived a long, productive life, says Ken Balcomb

Share

A 43-year-old male orca named Mega, now missing and presumed dead, was one of the first new calves that researcher Ken Balcomb spotted when he began his extensive census of Southern Resident killer whales back in 1976. Ken didn’t know it at the time, but the baby orca — one of nine born in 1977 — would grow to become a large, powerful whale, living up to his name by fathering at least 20 offspring of his own. Designated L41, Mega was around throughout Ken’s career at the Center for […]

How air pollution becomes water pollution with long-term effects on Puget Sound

Share

When thinking of air pollution, I used to think only of breathing toxic chemicals into our lungs, with uncertain health effects. That’s bad enough, but air pollution — which is everywhere — is also getting into our waterways and penetrating deep into our food webs. Rivers, lakes and Puget Sound, no body of water escapes toxic chemicals dropping out of the sky. Until recently, I never gave much thought to the chemicals riding on air currents, secretly falling to the ground, especially during rainstorms. I began to look at the […]
