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.

High ice content permafrost bluff erosion at Barter Island in 2019 after several coastal storms and a prolonged time of anomalously high air temperatures. 

Evolution of the shoreline around the Elwha River mouth, Washington, before, during and after dam removal, 2011–2017. Two large dams were removed from the Elwha River between 2011 and 2014 in the largest dam removal worldwide thus far, releasing more than 20 million tons of sediment downstream.

Once removed from the pressure core testing tool, this specimen shows that it is not a homogeneous sediment.  The mostly fine-grained sample (dark sediment in all three images) easily breaks apart at a thin layer of coarse-grained sediment (light sediment on the inner core surfaces of images (i) and (ii).

 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

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.
