USGS scientists headed up river this June to see whether two Asian clams had also headed upstream with the drought. When there’s less fresh water flowing out to sea, salty ocean water intrudes inland, and changes the distribution of these pesky invertebrates. Potamocorbula like it saltier than Corbicula, and usually hang out in the Suisun Bay region. But scientists suspect drought conditions may have changed all that, and with it, how and when the contaminant selenium gets cycled through the...Read More

There’s no better example than Pond A8, where the Guadalupe River enters San Francisco Bay via Alviso Slough. Restoration planners were worried that connecting the former salt evaporation pond with the Bay could introduce long-dormant mercury to the wider ecosystem, and initial studies of levels in water...Read More
