Physical scientist Jackson Currie steers a personal water craft (PWC) equipped with GPS and echo sounder through the waves of the nearshore area of Zmudowski State Beach in Moss Landing, California.

Location: Laysan Islands (Northwestern Hawaiian Islands).

Seafloor image at a deepwater (~1400 m water depth) seep site on the New England margin. Seafloor conditions here are well inside the pressure-temperature stability field for methane hydrate. Gas being emitted below the rock overhang has formed gas hydrate (the white ice-like material). Distinct bubbles are visible in the foreground. The red laser scale is 10 cm.

Photograph of shallow-water coral bleaching at Sombrero de Pelo reef in Pacific Panama during the 2015-2016 El Nino event. Because of the influence of internal waves, corals growing at deeper locations at this site did not bleach.

Pacific Ocean temperature differences during this winter’s record-setting El Niño. Dark red areas are much warmer than average.

Sea surface temperature differences on March 1, 2016. Dark red indicates much warmer water.

USGS geologist Jamie Conrad uses a map of the seafloor off Southern California to plan high-resolution mapping southwest of Santa Catalina Island. Small inset shows seafloor data collected by the ship that reveals hills, gullies, and basins.

A ship will tow this green cable, which contains underwater microphones that record sound reflected off layers beneath the seafloor. USGS scientists will use the data to pinpoint the location of faults.

The USGS Coastal and Estuarine Dynamics Group will be deploying a Nanopod at Pea Island DUNEX experiment site to collect oceanographic information.

USGS scientists survey a beach near San Francisco to assist with a comparison of data derived from aerial photos and lidar.

The coastal bluff along East Cliff Drive in Santa Cruz, California are especially vulnerable to rising sea level during big storms. Sometimes even the rip-rap, put in place to protect roadways and homes, cannot protect the bluffs from erosion.

View of the Santa Cruz Beach Boardwalk amusement park in Santa Cruz, California. Photo was taken from the bluff on East Cliff Drive, east of the San Lorenzo River mouth. Sand on the beach gets eroded, redistributed, and deposited due to the dynamic conditions brought about by storms and changing river flow.
