Ocean conditions contributed to unprecedented 2015 toxic algal bloom

A study led by researchers at the University of Washington and the National Oceanic and Atmospheric Administration connects the unprecedented West Coast toxic algal bloom of 2015 that closed fisheries from southern California to northern British Columbia to the unusually warm ocean conditions — nicknamed “the blob” — in winter and spring of that year. “We have toxic algae events that result in shellfish closures off the Washington and Oregon coast every three to five years or so, but none of them have been as large as this one,” said lead author Ryan McCabe, a research scientist at the UW’s Joint Institute for the Study of the Atmosphere and Ocean, a collaborative center with NOAA.

10 UW Environment stories you may have missed over the summer

Journal pages list all the species of plants the UW Environmental Studies class has seen by the penultimate day of their backpacking trip in the Olympic National Park backcountry. Here, the group takes a break at Grand Pass.

At the conclusion of a long and arduous academic year, many students look forward to the rest and relaxation that comes with summertime. But while many are enjoying the glorious downtime of a few months without classes, others — faculty, undergrads, graduate students and postdocs — are in the field and in labs pushing their research forward. The summer of 2016 was no different.

Missing fish catch data? Not necessarily a problem, new study says

Recording how many fish are caught is one important requirement to measure the well-being of a fish stock — if scientists know the number of fish taken from the ocean, they can adjust management of that fishery to keep it from being overfished. Missing catch data, however, are rampant, causing concern that fisheries around the world are overfished. A new study by University of Washington scientists finds that in many cases, this isn’t true.

Invasive green crab found on San Juan Island by citizen science volunteers

A European green crab (Carcinus maenas, meaning “raving mad crab”) found earlier in Willapa Bay, Washington.

Earlier this week in Westcott Bay, San Juan Island, a team of volunteer monitors caught an invasive green crab, marking the first confirmation of this global invader in Washington’s inland waters. The volunteers are part of Washington Sea Grant’s Crab Team, an early detection and monitoring program to look for European green crab (Carcinus maenas) and collect information on local marine life.
