Overview

The primary purpose of this trip was to conduct fish and benthic surveys at East and West Flower Garden Banks in preparation for a proposed research area recommended by the 2012 Management Plan through the Management Plan Review process.

Data Collection

Researchers conducted both benthic habitat and fish surveys at randomly selected locations across the reef, including parts of the reef rarely visited.  They also conducted a reconnaissance dive at HIA389A, a gas production platform within sanctuary boundaries at East Flower Garden Bank.

In addition, we collected routine water samples as part of the long-term monitoring program.

Conditions

Water temperature was 88F (31F) at depth.

Sightings

The beginning of a severe bleaching event was documented at East and West Flower Garden Banks.  Bleaching species included Millepora alcicornis, Montastraea cavernosa, Siderastraea siderea, and Orbicella (Montastraea) franksi.

Several manta rays were encountered and photographed for addition to the catalog.

On the return trip, we also made a dive at Stetson Bank. Visual observations suggested 99% of the fire coral (Millepora alcicornis) was bleached

Mardi Gras wrasse (Halichoeres bureki)  were observed at both West Flower Garden Bank and Stetson Bank.

There was very little benthic cover on the 60’ peak, but was quite lush benthic cover at the 80’ peak – dominated by sponges.
