Rebreather fish surveys in the Main Hawaiian Islands from 2015-06-14 to 2015-08-13 (NCEI Accession 0157574)

These data come from surveys conducted using close-circuit rebreathers. The use of rebreathers is intended to provide data that can be compared against data gathered on open-circuit SCUBA, which is the breathing apparatus typically used by CREP.

The survey domain encompassed hard bottom habitats in the Main Hawaiian Islands and the stratification included island, reef zone, and depth. Sites were surveyed using the stationary point count (SPC) method to quantify reef fish assemblages. At each survey site, fish biologists entered the water and conducted paired fine-scale (~700 square meters) and high degree of taxonomic resolution Rapid Ecological Assessment (REA) survey to assess species diversity, size distribution, and abundance of fishes at the site.
