Maps, Tools & Applications

This Data Explorer Map contains ecological and socioeconomic datasets including management boundaries, human use activities, fish and oyster surveys, and benthic habitats in the NOAA Choptank Habitat Focus Area (HFA) Ecosystem Assessment. The tool allows managers, stakeholders and the general public to visualize data that assists with decision-making about management of the ecosystem in the Choptank watershed.

NS&T is comprised of three nationwide programs, Benthic Surveillance, Mussel Watch and Bioeffects that are designed to describe the current status of, and detect changes in, the environmental quality of our nation's estuarine and coastal waters through environmental monitoring, assessment and related research. In addition, NS&T has also completed special studies designed to help assess the environmental impacts of various events.

NCCOS scientists have developed an easy-to-use numerical wave exposure model (WEMo) that uses linear wave theory to calculate actual wave height and derived wave energy while taking into consideration wind generation and local water depth characteristics such as shoaling and dissipation from breaking waves. WEMo also provides predictions of seafloor sediment movement.

Data & Publications

A comparison of seafloor habitats and associated benthic fauna in areas open and closed to bottom trawling along the central California continental shelf

A number of studies have shown that mobile, bottom-contact fishing gear (such as otter trawls) can alter seafloor habitats and associated biota. Considerably less is known about the recovery of these resources following such disturbances, though this information is critical ...

A coupled physical-biological model of the Northern Gulf of Mexico shelf: model description, validation and analysis of phytoplankton variability

The Texas-Louisiana shelf in the Northern Gulf of Mexico receives large inputs of nutrients and freshwater from the Mississippi/Atchafalaya River system. The nutrients stimulate high rates of primary production in the river plume, which contributes to the development of a ...
