U.S. Geological Survey (USGS) scientists, in collaboration with the National Oceanic and Atmospheric Administration (NOAA) and PRBO Conservation Science (formerly Point Reyes Bird Observatory), recently released the beta version of an interactive tool for assessing climate-change impacts along the north-central California coast.

Salt marshes may help slow the rate of climate change in the future, as rising and warmer oceans will enable them to more quickly capture and remove carbon dioxide from the atmosphere, according to a study published in the journal Nature.

U.S. Geological Survey (USGS) scientists and academic colleagues investigated how California's interconnected San Francisco Bay and Sacramento-San Joaquin Delta (the Bay-Delta system) is expected to change from 2010 to 2099 in response to both fast and moderate climate-warming scenarios.

Over the coming decades, California's Bay-Delta system will feel impacts of global climate change with shifts in biological communities, rising sea level, and modified water supplies, according to a new study by the USGS and academic partners.

On a bright day in early February, 2011, U.S. Geological Survey (USGS) research oceanographer Jessica Lacy and USGS Mendenhall Fellow Lissa MacVean supervised the placement of aluminum platforms bristling with instruments into San Francisco Bay, California, for 6 weeks of gathering data on how bay waters move sediment.

Thanks to the efforts of many, the USGS was able to assist NOAA in acquiring sediment samples on the California continental shelf and to obtain additional samples for USGS studies of contaminant transport in the Pacific Ocean offshore of San Francisco.
