Paul Montagna


A compilation of meiofauna data collected around the Gulf of Mexico. The data from the following 6 projects is included: National Resource Damage Assessment, Deep Gulf of Mexico Benthos Program, Rigs/Reefs, C-Image II Ixtoc, Gulf of Mexico Offshore Operations and Monitoring Experiment, and Northern Gulf of Mexico Continental Slope study. The date of collection ranges from 1983-2015. The data-set includes project name, station name, station location, station depth, sample date, replicate number, richness, abundance, nematode to copepod ratios, Shannon's Diversity, Evenness, and Hill's N1 Diversity. Meta-analysis of Gulf of Mexico Macrofauna data collected from 1983 to 2015 is available under GRIIDC UDI R6.x805.000:0062 (doi:10.7266/n7-4g22-3t28).

Ixtoc: Data from C-IMAGE-II for locations in the southern GoM near the Ixtoc oil spill site. Deep Gulf of Mexico Benthos Program (DGOMB): Data from Baguley et al., (2006) for the northern GoM. Gulf of Mexico Offshore Operations Monitoring Experiment (GOOMEX): Data from Montagna and Harper, (1996) for the northwestern GoM near five hydrocarbon production platforms. Rigs vs Reefs Experiment (EPA97): Data from Montagna et al., (2002) for the northwestern GoM near three hydrocarbon production platforms. Northern Gulf of Mexico Continental Slope Study (NGOMCSS): Data from Galleway (1988) for location in the central GoM.||||Baguley, J. G., P. A. Montagna, C. Cooksey, J. L. Hyland, H. W. Bang, C.
