Two-toned blue dashed line

The purpose of this expedition was to continue data collection as part of the Natural Resource Damage Assessment (NRDA) in response to the Deepwater Horizon Oil Spill.

Participants

R/V Manta crew
Sanctuary research team
Texas A&M Galveston AAUS divers

Overview

Divers completed random transect photography and fish counts at West Flower Garden Bank as part of the long-term monitoring effort that was started in August. 

Semi-permeable membrane devices (SPMDs) were changed out at East and West Flower Garden Banks and Stetson Bank as part of the ongoing Deepwater Horizon oil spill response effort.

SPMDs are attached to a submerged buoy line at each of the banks. These are retrieved and new ones deployed at regular intervals. Photo: Schmahl/FGBNMS

Conditions

Water temperatures at depth had decreased to 79F (26C), which should alleviate the bleaching event.
