U.S. Geological Survey scientist walks on a coastal bluff in Alaska.

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.

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.

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.

Two USGS scientists measure elevation at Bass Creek salt marsh, Yarmouth, MA. 

USGS scientists are working to model shorebird habitat availability both today and in the future, given processes like sea-level rise, in an effort to support the efficient management of beaches for both people and nesting shorebirds.

Composite aerial view of Sandwich Town Neck Beach. The imagery was obtained from an unmanned aerial system (UAS) flown by Peter Traykovski in February, 2015, a few days after winter storm Juno. The background topography is from USGS and U.S. Army Corps of Engineers lidar data, with missing-data areas shown in white.
