MARMAP Chevron Trap Survey
Fish abundance and biomass data collected during the day using chevron traps on the coast of the southeastern United States by the Marine Resources, Monitorring, Assessment and Prediction Program (MARMAP) are available at OBIS. The OBIS compiled data includes species name, individual count, lat/lon, and some environmental correlates like depth and salinity.

Data Collection Summary / Methods: Abundance and biomass of fish was collected using chevron traps during the day.
From OBIS metadata - "Chevron traps were set on live-bottom reef areas on the continental shelf and upper slope. Chevron traps were arrowhead shaped (maximum dimensions of 1.5 m x 1.7 m x 0.6 m.; 0.91 m3 volume) and constructed of 35 mm x 35 mm square mesh plastic-coated wire. Chevron traps had one entrance funnel (“horseneck”), and one release panel to remove the catch. Each trap was soaked between 90 and 120 minutes."
