I've asked quite a few of the elders here if they had ever seen and none of them said they had ever seen it, said Skidegate Chief Councillor Bill Yovanovich, who took the photos Saturday on Lina Island. They show small bits of white shells arranged into what appears to be an intentional grid pattern that stretches at least a hundred metres along the beach.

Just at a time when crab stocks in the central Gulf of Alaska are taking off, likely in part due to crashing cod populations, a new study funded by the National Oceanic and Atmospheric Administration shows that ocean acidification is damaging the shells of young Dungeness crab in the Pacific Northwest, an impact that scientists did not expect until much later this century.

In first-of-its-kind research, NOAA scientists and academic partners used 100 years of microscopic shells to show that the coastal waters off California are acidifying twice as fast as the global ocean average—with the seafood supply in the crosshairs.

Similar to what has happened in B.C., tens of millions of voracious purple sea urchins have chomped their way through towering underwater kelp forests in California.

We did not see a single sea star in the Kachemak-side tide pools, and boulders we visit each year all looked a little vacant, with a lot of empty, critter-free space.

The results of the Plate Watch program only indicated one invasive species in the area, Caprella mutica, otherwise known as the Japanese skeleton shrimp.

Sea Star Wasting Disease has caused sea stars to die off since 2013. As of 2018, there are still no sea stars on Bishops Beach in Homer.

We discovered numerous large marine bivalve shells (and two chiton shells) that had been cracked recently by sea otters. Ocean View Beach is around the southern extent of Vancouver Island and back again north in the Strait of Georgia. The present observation is evidence of sea otters traveling into the Strait of Georgia.

Sea star wasting disease, a type of densovirus, reduced the count of sea stars in Kachemak Bay from 180 last spring to a measly five this year.

A winter storm lashed the sandy beaches at the mouth of the Ninilchik River with ferocious waves, powerful enough to uproot thousands of razor clams.
