Purpose
|
|
Study of benthic habitats, biota, and geologic substrate at Flower
|
|
Garden Banks National Marine Sanctuary, Gulf of Mexico, using sampling equipment
|
|
and ROV-Innovator; also investigation of deep-sea corals at deep sites in
|
|
Mississippi Canyon and surrounding areas

|
|
Information to be Derived
|
|
Samples and Chemical Analysis; Bathymetric Maps; Bottom video, digital
|
|
still photos, samples of benthos and substrate, multibeam bathymetry (all
|
|
archived by NOAA and participating biologists except approximately 12 rock/coral
|
|
samples and 2 bottom water samples retained by USGS);water samples will be
|
|
analyzed for 14C.

Summary
|
|
The National Oceanic and Atmospheric Administration (NOAA)'s Office of
|
|
Exploration (OE) sponsored a recent cruise on the NOAA ship Ronald H. Brown to
|
|
explore deep-water-coral habitats (at depths ranging from about 200 to 2,000 ft)
|
|
along the shelf edge and in canyons of the northern Gulf of Mexico, including
|
|
sites previously mapped by USGS emeritus scientist Jim Gardner and others. Some
|
|
topographic features in the Gulf of Mexico have been identified as crucial
|
|
spawning sites for commercially important fishes and reef-building deep-water
|
|
corals. Cruise participants sought to learn more about the deep-water-coral
|
|
systems and their inhabitants, whose abundance, extent, and diversity in the
|
|
gulf are poorly understood. A better understanding of these fragile and
|
|
potentially valuable resources can assist management decisions in this region of
|
|
extensive human activity.
|
|
|
|
The USGS participated in this cruise as part of its ongoing commitment to
|
|
provide geologic-science support to NOAA in its characterization and management
|
|
of the resources of national marine sanctuaries and other important habitats.
|
|
|
|
The cruise departed from Panama City, FL, on September 21 and ended in Gulfport,
|
|
MS, on October 2, successfully navigating the difficult End-of-Fiscal-Year
|
|
Passage. [Note to non-USGS readers: it is logistically complex to conduct field
|
|
operations across the start of the Federal Government's new fiscal year, which
|
|
begins on Oct. 1.] The primary device used for data collection was Sonsub's
|
|
remotely operated vehicle (ROV) Innovator 12, a working-class ROV used primarily
|
|
on offshore oil rigs and pipelines. Cruise personnel conducted 11 ROV dives at
|
|
deep sites near Mississippi Canyon, Green Canyon, and Viosca Knoll and at
|
|
shallower sites at Diaphus Bank and West Flower Garden Bank, as well as some
|
|
multibeam bathymetric mapping. Samples of fish, deep-sea corals, echinoderms,
|
|
crustaceans, algae, mollusks, sponges, rocks, tube worms, water, and sediment
|
|
were collected by using the ROV. The dives were documented by about 50 hours of
|
|
video footage and several hundred still photographs and samples.
|
|
|
|
The science plan was designed by personnel from the Flower Garden Banks National
|
|
Marine Sanctuary (FGBNMS) and the University of Alabama, Dauphin Island (DI).
|
|
Chief scientists were G.P. Schmahl (FGBNMS) and Will Schroeder (DI, not on
|
|
board); John McDonough (OE) served as cruise coordinator. John Bratton (USGS,
|
|
Woods Hole, MA) provided input on geologic framework of habitats, hard-substrate
|
|
lithology, sedimentology, and influence of sea-level change on the systems.
|
|
Thirteen other scientists and science-support personnel participated, including
|
|
Emma Hickerson (FGBNMS), Doug Weaver (FGBNMS), Mary Wicksten (Texas A&M
|
|
University), Peter Etnoyer (Marine Conservation Biology Institute), Susanne
|
|
Fredericq (University of Louisiana, Lafayette), Ron Hill (National Marine
|
|
Fisheries Service, Galveston, TX), Julie Olson (University of Alabama), Sandra
|
|
Brooke (Oregon Institute of Marine Biology), and Brett Phaneuf (Texas A&M
|
|
University). Staff from C&C Technologies, Inc., were responsible for underwater
|
|
navigation.
