 Two UNC mini landers, surrounded by Sablefish (Anoplopoma fimbria) and pink sea urchins, incubate seawater in situ to enable calculations of methane oxidation rates.

Red plumes burst out from the tops of these chemosynthetic tubeworms, capturing hydrogen sulfide and oxygen from the surrounding water to feed their bacterial endosymbionts. The tubeworm tubes provide a habitat for several benthic animals, including the pale pink branching octocorals seen here

Coastal and Marine scientists collect data in the field. 

Multibeam bathymetry shown in the spectrum from red (shallower) to blue (deeper) for depths greater than 200 m across the head of Astoria Canyon. The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes.  The modern Columbia River is far right.

Topography and bathymetry of southern Cascadia, which includes southern Oregon and northern California (seafloor depths between 200 and 3000 m are shown in the spectrum color scale from red (shallower) to purple (deeper). The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes.

Several instruments visible on board the research vessel JOIDES Resolution. Photo taken from the ship bridge roof. USGS logo visible on one of the pieces of equipment. Research cruises taken on the JOIDES Resolution are often interdisciplinary and collaborative across many universities, scientific agencies, and other research institutions.

Mounds of sand cleared from the roadway stand high on both sides of a road near the beach in Pensacola Beach, Florida, in October 2004 after Hurricane Ivan.

U.S. Geological Survey (USGS) researcher Dave Thompson stands next to a garage in Gulf Shores, Alabama, that filled with sand after Hurricane Ivan in 2004.

This coral garden was discovered in the Stetson-Miami Deepwater HAPC during the 2019 Southeastern U.S. Deep-sea Exploration in an area that may mark the eastern extent of the Million Mounds region.

Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys. Pictured here is a coral at Crocker Reef in the upper Florida Keys.
