Cover Story

Are Invasive Plants Trapping the Sediment that a Healthy Estuary Needs? Sweating the Small Stuff in California’s Sacramento-San Joaquin River Delta
In recent years, invasive aquatic plants have increased exponentially in the shallow waters of California’s Sacramento-San Joaquin River Delta, clogging about 17,400 acres (nearly 30 square miles) of the waterways. Among the plants’ many effects are changes in the way mud and sand move through the region.


Recent Fieldwork
USGS scientists visited seven coastal and offshore locations studying methane seeps in the North Sea, coral reefs in American Samoa, marshes in Massachusetts, and more. Here’s a quick overview of some fieldwork by our researchers.


Raising Awareness in the Classroom about Natural Hazards Facing U.S. Coastal Communities
USGS scientists present newly developed education outreach materials at the Smithsonian Science Education Academy for Teachers (SSEATs) held at the USGS National Headquarters in Reston, Virginia.
