Plastic pollution in the oceans is an equity issue, says UW-led report

Many people are aware of plastic pollution in the oceans. Photos of turtles or seabirds entangled in plastic garbage first went viral in the 1990s, and the Great Pacific Garbage Patch is now the focus of highly publicized cleanup efforts. Less recognized is how marine plastic waste affects human populations, and the unequal burden on different communities. A report, “Towards an Equitable Approach to Marine Plastics Pollution,” outlines the current situation and attempts to address the problem.

Warming oceans have decimated marine parasites — but that’s not a good thing

A researcher holds open a preserved fish specimen that has been inspected for parasites.

More than a century of preserved fish specimens offer a rare glimpse into long-term trends in parasite populations. New research from the University of Washington shows that fish parasites plummeted from 1880 to 2019, a 140-year stretch when Puget Sound — their habitat and the second largest estuary in the mainland U.S. — warmed significantly. The study, published the week of Jan.

Strongest Arctic cyclone on record led to surprising loss of sea ice

A ship-based view of the Arctic Ocean where the ocean surface is starting to freeze.

A warming climate is causing a decline in sea ice in the Arctic Ocean, where loss of sea ice has important ecological, economic and climate impacts. On top of this long-term shift due to climate change are weather events that affect the sea ice from week to week. The strongest Arctic cyclone ever observed poleward of 70 degrees north latitude struck in January 2022 northeast of Greenland.

Study reveals how ancient fish colonized the deep sea

The deep sea contains more than 90% of the water in our oceans, but only about a third of all fish species. Scientists have long thought the explanation for this was intuitive — shallow ocean waters are warm and full of resources, making them a prime location for new species to evolve and thrive. But a new University of Washington study led by Elizabeth Miller reports that throughout Earth’s ancient history, there were several periods of time when many fish actually favored the cold, dark, barren waters of the deep sea.

Annual research trip off Oregon coast gives students once in a lifetime experience at sea

Most things that humans build need a little maintenance every now and again. That’s no different for the Regional Cabled Array, a high-tech engineering marvel off the Pacific Northwest coast studded with all kinds of oceanographic equipment that gives humans a real-time, 24/7 look at what’s happening under the sea surface. The lengths that scientists and engineers go to keep the array working and up to snuff is extraordinary, and they are currently at sea providing its annual check-up.
