PIR Marine Turtle In Water Captures & Observations
공공데이터포털
Effective management of marine turtle data is essential to maximize their research value and enable timely population assessments and recovery monitoring. To provide such capabilities at the National Marine Fisheries Service, a comprehensive Turtle Data Processing System (TDPS, formally called Marine Turtle Data Management System) was created. The system was written in DBase III and Clipper and implemented on IBM/PC-compatible computers running under MS-DOS. As of 2003, TDPS was upgraded into Microsoft Access. The TDPS is modular, supporting data of various types. Cross-referencing and multiple-encounter analysis are enabled through a core database file of individual turtle identifications, based on uniquely-inscribed flipper tags and passive-integrative transponder tags.
SEAMAP Reef Fish Survey Videos
공공데이터포털
The Southeast Fisheries Science Center Mississippi Laboratories conducts standardized reef fish video surveys in the Gulf of Mexico since 1992. The survey primarily occurs on the outer continental shelf along topographic features (e.g. reefs, banks and ledges) between Brownsville, TX to the Dry Tortugas, FL, and provides fisheries independent indices of reef fish abundance for use in stock assessments.
Madison-Swanson MPA reef fish video survey

The Southeast Fisheries Science Center Mississippi Laboratories conducts standardized fisheries independent resource surveys in the Gulf of Mexico, South Atlantic, and U.S. Caribbean to provide abundance and distribution information to support regional and international stock assessments. The reef fish survey of Madison-Swanson and Steamboat Lumps MPA is conducted primarily on the along topographic features (e.g. reefs, banks and ledges) of the MPA. A two-stage sampling design is used with the first stage or primary sampling units defined by geographic/geoform strata including ridges, pinnacles, rubble and sand flats and the second stage being randomly selected sites within the geoform strata. Sampling is conducted using a video camera array. No biological sampling is coupled with the survey because of the areas status as an MPA. The camera array consists of four housings positioned orthogonally and center mounted at a height of 51 cm above the bottom of the array. Each housing contains a pair of black-and-white Videre stereo cameras along with a color mpeg camera. Sampling of reef sites with video cameras occurs only during daylight hours, with the first gear deployment one hour after sunrise and the last gear retrieval one hour prior to sunset. Video arrays soak for 35 minutes. Habitat mapping was conducted using a multibeam echosounder by USGS. At each site hydrological data is collected using Conductivity Temperature Depth sensor (CTD).
