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.
