Abstract
Reef fish community structure and species diversity were examined by estimating reef fish densities (per 1,000m^3) using VideoRay Pro 4 remotely operated vehicle (ROV) video sampling. 22 individual natural reef sites were surveyed in the period 2012-03-13 to 2014-08-25. The density of 117 different species was measured over the period. Related data may be found under GRIIDC Unique Dataset Identifiers (UDIs): R1.x135.120:0020 (DOI: 10.7266/N7J38QKR, artificial reef sites) and Y1.x049.000:0003 (DOI: 10.7266/N72J68SF, natural reef sites 2010-2011).
Purpose
To examine reef fish community structure and species diversity following the Deepwater Horizon oil spill.

Supplemental Information
Fish common name, fish family, fish genus, fish species, fish density [individuals/1000^3] (columns labeled with reef site name and sampling date). ‘Additional Info’ worksheet includes sampling number [1-117], date [YYYY-MM-DD], site [reef name], latitude [degree, decimal minute N], longitude [degree, decimal minute W], camera [VideoRay ROV or GoPRo Hero2], FOV (field of view of lens, [degrees]), resolution [570 lines of resolution or 1080 pixels], color or black and white, fps (frames per second, [30 or 60]).|The area surveyed was computed by multiplying transect width (m), estimated as the product of the height of bottom (1 or 2 m) and the tangent of half the camera field of view, by the sum of all four transect lengths (100 m). Individual species counts were summed among transects and divided by the total area surveyed to estimate fish density.|VideoRay Pro 4 Remotely Operated Vehicle (ROV), GoPro Hero2 camera|VideoRay 30 fps, GoPro Hero2 60 fps||
