Habitats

The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington.

From May of 2018 through November of 2019, USGS scientists collected imagery from video cameras overlooking the coast along a beach on Whidbey Island, Island County at the northern boundary of Puget Sound in western Washington.

The overall objective of this research effort is to better understand how circulation and sediment processes impact coral reefs.

From June 12 to July 3, 2019, the USGS sailed onboard Schmidt Ocean Institute’s R/V Falkor with several other partners, seeking methane seeps along the seafloor of several underwater canyons off the coast of Oregon and Washington. On this cruise, USGS scientists will seek to understand how much methane is coming out of these seeps, how it travels through the water column, and its ultimate fate in...

Here we describe the data collection methods and techniques of the California Seaflor Mapping Program: mapping, video and photography ground-truthing, and seismic profiling data collection.

USGS and the California Ocean Protection Council (COPC) are supporting development of peer-reviewed map sets for California’s mainland State Waters.

The map sheets display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow (to about 100 m) subsurface geology. The total number of sheets varies by area.

California Seafloor Mapping Program data and map publications have and will be used for a large range of applications in coastal zone management and research.
