Fisheries Oceanography in Coastal Alabama (FOCAL): A Time-Series of Hydrographic and Current Data from a Permanent Moored Station Outside Mobile Bay (2006-2012)

Dataset extent

The Fisheries Oceanography in Coastal Alabama (FOCAL) program began in 2006 as a way for scientists at Dauphin Island Sea Lab (DISL) to study the natural variability of Alabama's nearshore environment as it relates to fisheries production. FOCAL provided a long-term baseline data set that included time-series hydrographic data from a permanent offshore mooring (ADCP, vertical thermister array and CTDs at surface and bottom) and shipboard surveys (vertical CTD profiles and water sampling), as well as monthly ichthyoplankton and zooplankton (depth-discrete) sample collections at FOCAL sites.

The subset of data presented here are from the mooring, and includes a vertical array of thermisters, CTDs at surface and bottom, an ADCP at the bottom, and vertical CTD profiles collected at the mooring during maintenance surveys. The mooring is located at 30 05.410'N 88 12.694'W, 25 km southwest of the entrance to Mobile Bay. Temperature, salinity, density, depth, and current velocity data were collected at 20-minute intervals from 2006 to 2012. Other parameters, such as dissolved oxygen, are available for portions of the time series depending on which instruments were deployed at the time.
