USGS Role in DEEP SEARCH: Deep Sea Exploration to Advance Research on Coral, Canyon, and Cold-seep Habitats

USGS scientists are collaborating with multiple agencies to provide the esssential foundation for understanding these deep-sea environments.

Coral Microbial Ecology

The coral microbial ecology group has an active research program identifying and characterizing the microbial associates of both tropical and cold-water (deep-sea) corals and their surrounding habitat. Current projects focus on coral disease dynamics, bacterial diversity, and using metagenomics to elucidate the functional roles of coral microbes.

Coral Reef Ecosystem Studies (CREST)

The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Paleoceanographic Proxy Calibration

A sediment trap time series in the northern Gulf of Mexico is used to better assess the control of environmental variables (e.g., temperature and salinity) on the flux of both microfossils and molecular fossils to the sediments. The information gained from sediment trap studies is used to develop better proxy-based estimates of past oceanographic conditions from analyses of microfossils and...
