Green Canyon Area, St. Tammany Basin (GC939)

Dive Track

Area

Gulf of Mexico

Overview

Date: December 12, 2017
Max Depth: 1635 Meters
Bottom Time: 6 Hours 4 Minutes 49 Seconds

Purpose

The dive site was located near to a proposed Flower Garden Banks National Marine Sanctuary expansion zone, as well as a Habitat Area of Particular Concern (HAPC) proposed by the Gulf of Mexico Fishery Council. Extensive previous exploration and the presence of a pipeline in the proposed areas limited potential dive locations within proposed areas. Additionally, several methane bubble plumes and potential hard grounds detected approximately five kilometers south during multibeam surveys by the NOAA Ship Okeanos Explorer resulted in the dive being planned outside of proposed areas for management. Despite this, baseline data collected on the distribution, abundance, diversity, biogeography and connectivity of chemosynthetic communities and surrounding faunal assemblages, as well as the geological composition and origin of this area, will have implications for the management of these areas.

Wreck 15725 (KC530)

Dive Track

Area

Gulf of Mexico

Overview

Date: December 14, 2017
Max Depth: 1567.6 Meters
Bottom Time: 1 Hours 18 Minutes 12 Seconds

Purpose

This dive investigated a side scan sonar target thought to represent an archaeological site and related debris. As this was the first time the site was investigated, it was expected that a visual reconnaissance would be conducted, as well as an experimental mosaic survey, and inspection of diagnostic artifacts, features, and biological inhabitants. A survey of the debris field was also expected. However, upon reaching the site of the wreck, only recent human debris was observed. As a result, it was decided that the benthic portion of this dive would be shortened to accommodate midwater exploration at depths of 1000m, 900m, 800m, 700m, 600m, 500m, 400m and 300m.
