Waves breaking over offshore reefs on Kwajalein Atoll, in the Marshall Islands, where reefs are protecting developed land from flooding.

USGS technician Barry Irwin uses a GPS rover system to locate one of the targets used to calibrate the field of view for the beach cam. Three other larger targets are visible in the background.

This flooded airport runway used to be the main lifeline for inhabitants of Barter Island, Alaska, before it was relocated in response to consistent flooding.

This bathymetric grid represents approximately 3900 kilometers of bathymetric data collected in 2014. These data were collected using a dual-head R2Sonic 2024 multibeam echosounder (MBES) by Alpine Ocean Seismic Survey, Inc., during USGS field activity 2014-072-FA.

Divers prepare patterns of known targets for verification of sonar resolution.

USGS scientists walk through a tern colony on the Monomoy National Wildlife Refuge (MA). Here, these scientists are using ecogeomorphological models to predict how this refuge will be impacted by sea-level rise and how that will ultimately effect shorebirds.

Piping plover chicks are well concealed in shallow nests on sandy beaches.

Scientists collect soil cores in coastal wetland by removing a section of peat, the organic-rich material that makes up salt marshes. After the soil is removed, water quickly fills in the void. This water-logged environment underground is devoid of oxygen and is an important reason that salt marsh peat preserves a record of historical changes.

Meagan Eagle, Research Scientists at the U.S. Geological Survey, collects an elevation point along the edge of Quivett Creek in Brewster, MA. This salt marsh was restored in 2005 by replacing a narrow culvert to allow full tidal flow once again.
