EOP Fish and coral surveys using submersible and ROV dives in the Hawaiian Archipelago

A series of dives were conducted from 1998 to 2003 through out the Hawaiian Archipelago using the Hawaii Undersea Research Laboratory's ROV RCV-150 and submersibles Pisces IV and Pisces V. The dives were focused on surveying subphotic fish assemblages (300-500 m) in relation to patches of deep corals and relative to regional differences in oceanic productivity.

The University of Hawaii HURL assets were used to conduct two studies. First was and evaluation of fish association with precious corals which are the subject of commercial harvest. Second was to look for patterns in the biomass of the fish assemblages relative to regional differences in oceanic productivty.

Rational data table which includes scored variables from video tape. Raw video tape is on file at the Hawaii Undersea Research Laboratory.

Text read me file is included that explains tabular database fields.

Text read me file is included so entities are defined.

Legacy data set.

Not applicable

Habitat code varied between survey years so columns were included that preserved the original habitat codes and new column that consolidated them for analysis.

Data was published within a year of completion of data collection.

All raw video data was available through Hawaii Undersea Research Laboratory (HURL) one year after collection.

Tabular data required time for processing with no allocated funds for analysis.

Legacy data set is stored in tabular form at PIFSC.

Raw video archived at Hawaii Undersea Research Laboratory (HURL)

Saved in multiple places at PIFSC.

On CD.

1) Raw video were reviewed

2) Fish, coral, habitat variables were documented using 5 minute survey segments as the sub or ROV was traveling.

3) Estimated fish lengths were used with research catch length weight statistics to generate weight estimates.
