Groundfish/Shrimp and Red Snapper trawl surveys conducted in the Gulf of Mexico from 1990-01-01 to 2014-12-30 (NCEI Accession 0147703)

The Southeast Fisheries Science Center Mississippi Laboratories has conducted standardized groundfish trawl surveys in the Gulf of Mexico since 1987. Prior to 1987, the summer survey was conducted under Southeast Area Monitoring and Assessment Program (SEAMAP) protocols; however, the fall survey operated independent of SEAMAP and dates back to 1972. Data from these standardized surveys were provided to the Natural Resources Damage Assessment (NRDA) to support assessment of the environmental impacts of the Deepwater Horizon oil spill which occurred in the Gulf of Mexico in 2010.

To provide data to support the Natural Resources Damage Assessment (NRDA) in order to evaluate the impacts of the Gulf of Mexico Deepwater Horizon oil spill.

Validation routines are applied during data entry to ensure the integrity of data collected. Data validation routines are also applied as data are migrated into the centralized data management system.

Data resides on Networked Attached Storage (NAS) environment. Security patches/updates are immediately applied to the host environment. Data is stripped/mirrored using RAID 50 technology to protect data from disk failure. Nightly backups are preformed and files are written to magnetic tape and stored in an onsite / offsite location.

As specimens are collected, total number of individual fish by species and lengths are taken and recorded into the shipboard data collections system. At the end of each survey data are reviewed for accuracy/relevance by chief scientists. Specimens that cannot be identified during the survey are identified in the laboratory.
