Meg Chadsey, WSG’s ocean acidifcation specialist, has teamed with scientists at NOAA ‘s Pacific Environmental Laboratory to provide hands-on seawater chemistry monitoring experience for several students from Eagle Harbor (on Bainbridge Island) and Garfield high schools. The students met at the NOAA Sandpoint campus on a recent cold November morning to analyze Puget Sound seawater samples they’d collected as part of their summer field work. The students conducted their first set of tests in a “container lab” — literally a shipping ...

Volunteering: Volunteers are being trained to conduct monthly (July–August) trapping and/or ...
