Coastal Ecosystems

The USGS studies geologic and oceanographic processes that create and maintain habitats for coral, clams, crabs, salmon, and other ocean and estuary inhabitants. USGS studies of currents, suspended sediment, and groundwater chemistry, for example, help assess natural and human influences on the health of coral reefs. High-resolution seafloor mapping characterizes the seabed as rocky, sandy, or muddy; and bottom photos help identify the organisms that occupy those habitats.
