Description:

This Cruise Report provides a detailed characterization of the benthic habitat, benthic macrobiota, and fish populations for each ROV dive site. Appendix 1 provides the complete species list and percent cover of benthic biota and substrate for each site at Pulley Ridge (PR) and Tortugas (T). Appendix 2 lists the fish species and their densities for each site. Prior to the cruises, we pursued a statistically rigorous sampling protocol for the ROV surveys. In ArcGIS a fishnet grid of 1 km x 1 km blocks were overlaid on the available bathymetric maps at both regions. A total of 42 random blocks were selected for the quantitative ROV surveys in 2012 and 2013 (28 for PR and 14 blocks for T). Within each sampling block (“site”), we conducted five random100-m transects with the ROV to characterize that block.
