PSBF CRUISE II
Two-toned blue dashed line

September 19-23, 2012
aboard R/V MANTA

Flower Garden Banks National Marine Sanctuary is partnering with LUMCON, UNCW-Wilmington, and Bureau of Ocean Energy Management to continue uncovering the secrets of the deepwater communities in the northwestern Gulf of Mexico.

The focus of this trip was ROV exploartion at Rankin and 28 Fathom Banks, east of East Flower Garden Bank. Besides the beautiful coralline algae and deep water coral communities encountered, the team came across a mud volcano!

Overview

The purpose of this trip was to identify Potentially Sensitive Biological Features (PSBF) in the areas surrounding Bureau of Ocean Energy Management (BOEM) No Activity Zones (NAZ). The data collected as part of these ROV surveys will then be used to determine if any changes are needed in those designations.

Launching the ROV for a dive takes many people to help get it safely off the boat! The orange cable runs from the ROV to the boat, providing power to the ROV and a live video feed to researchers on board.

Researchers watch the video feed and take notes on the biology they are observing in real-time. These notes include time stamps and geographic coordinates to help us identify important sections of video that they may want to study further.

In addition to ROV dives, sediment samples and water samples were collected. The sediment grab is a large clam-shaped object that is lowered to the bottom on a cable. Once on the seafloor a latch is released, allowing the clam shell to close and capture sediment. Then, it is pulled back to the surface with the sediment inside.
