Relative seagrass biomass in West Falmouth Harbor, MA, under current and potential future nitrogen loading scenarios. Seagrass biomass increases in western (seaward) portions of the harbor while eastern (landward) areas see new colonization by seagrass.

Seafloor trace of the Queen Charlotte-Fairweather fault (from top left to bottom right) offsets the edge of the Yakobi Sea Valley off southeast Alaska. This 700-mile-long fault has generated large earthquakes in the past. Future shocks—and tsunamis—could threaten coastal communities in the U.S. and Canada. (Color-coded depths, in meters, were mapped in 2015.)

These clams (Calyptogena spp.) were discovered in about 1000 meter-deep waters off the southern tip of Alaska near a 250-meter-high cone rising from the seafloor and 10 kilometers from the Queen Charlotte-Fairweather fault.

USGS scientists Chris Rowden, Larry Buschmann and Bob Holmes were on the Mississippi River at St. Louis taking streamflow measurements on New Years Eve. This information is critical to the National Weather Service, the U.S. Army Corps of Engineers and emergency managers in making flood predictions and response.
