2008 RESEARCH SUMMARY

Prepared by
Emma L. Hickerson
January 2009

A.  OVERVIEW

The purpose of this document is to report the activities of the Flower Garden Banks (FGBNMS) Research Team during 2008.  The team included Emma L. Hickerson (Research Coordinator), Jennifer DeBose (Research Specialist), and Marissa Nuttall (Research Assistant).

B. SUMMARY

The FGBNMS research team was involved in eight research cruises during the 2008 field season, at a value of approximately $93,500 for the shiptime, $49,000 of which came directly out of the sanctuary's Fiscal Year 2008 budget. Unfortunately eight days of Nancy Foster shiptime was lost due to generator failure.

A pool of 32 sanctuary personnel, scientists, and volunteer divers conducted approximately 340 SCUBA dives during the 2008 field season. Activities included biological surveys and collection, equipment maintenance, u-bolt installation, and image collection. Ten sanctuary permits were processed, and an additional 13 were ongoing.

C.  CRUISES
($ amount represents approximate shiptime value)

WATER QUALITY INSTRUMENT DEPLOYMENT
M/V SPREE ($10,000)
February 2-3, 2008

The Flower Garden Banks NMS supported a cruise to change out the YSI water quality instruments and install new Seabird temperature/salinity instruments.  Sanctuary staff worked with the long term monitoring contractor, PBS&J, to accomplish the tasks. 

Staff noted the presence of a plague-like coral disease that was affecting multiple colonies, and multiple species.  This is the fourth year that this unusual winter-time disease event has been document at the FGBNMS.  A 6’ goliath grouper was encountered on the reef cap – a rare sighting.  Spinner sharks were jumping at Stetson Bank.  Water temperature was approximately 68F at all three banks.

TABS BUOY RESPONSE CRUISE
R/V BROOKS MCCALL ($15,000)
February 9-10, 2008

On Friday, February 15th, 2008, Flower Garden Banks NMS staff responded to a call reporting that the TABS Buoy V, had broken loose from its mooring, and had become entangled in the coral cap at the East Flower Garden Bank (EFGB).  FGBNMS worked with Texas A&M University/GERG to obtain secure a response vessel, the Brookes McCall, and FGBNMS provided NOAA working divers to conduct in water operations. 

The chain and cable attached to the buoy were entangled in the reef in over 100 ft of water.  The FGBNMS team (G.P. Schmahl, Jennifer DeBose, and Tracy Hamburger) unshackled the buoy from the chain at depth, and laid the chain on the substrate for future recovery.  The buoy was recovered by the vessel before returning to shore ahead of heavy seas.

SHAKEDOWN CRUISE
R/V MANTA ($2,500)
March 19-20, 2008
Elliott Bay, Seattle, WA

The new Flower Garden Banks NMS research catamaran, the R/V MANTA, was accepted by the program on Thursday, March 13th, 2008, from the builders, All American Marine, Inc., in Bellingham, WA. 

The vessel was brought down to Seattle for sea trial operations during the week of March 17th, 2008.  Sanctuary Program Director Dan Basta and FGBNMS Superintendent G.P. Schmahl conducted inaugural water entries donning drysuits and snorkels off the R/V MANTA at the pier at Sand Point - Dan, of course, being the first off! 

The FGBNMS collaborated with Mike Overfield (ONMS - RUST Program), Mitchell Tartt (ONMS - HQ), Bob Pavia (ONMS - Seattle), and Dana Wilkes (ONMS - Small Boat Program) to conduct sidescan and remotely operated vehicle (ROV) surveys of two RUST target sites in the vicinity of Elliott Bay, Seattle.   The primary objective of the mission was to test the capabilities of the R/V MANTA, and run the vessel systems.  The RUST (Resource and UnderSea Threats) targets, Four Mile Rock Barges, and the AJ Fuller (a schooner that had been converted to a gravel barge) were both successfully mapped and video image collected.  Technicians from Teledyne Benthos (Darren Moss), and Seafloor Systems (John and Tim Tamplin) loaned the mission their expertise and equipment to run the survey operations. 

The Assistant Archaeologist for the State of Washing, Scott Williams, was on hand to observe the operations, along with Olympic Coast NMS representatives, Bob Steelquist and George Galasso, and Seattle Aquarium representatives.  Other participants included Ruth Yender from NOS/ORR and Mark Miller from the NOAA Small Boat Program.   The R/V MANTA was also on site during the ONMS Small Boat Summit in Seattle in April. 

The vessel then returned to All American Marine, Inc., for final adjustments, before heading to Nanaimo, BC, Canada, in preparation for loading on a Dockwise transport ship for delivery to Fort Lauderdale, FL.

SPRING RESEARCH CRUISE
M/V FLING ($13,500)
April 28-30, 2008

The Flower Garden Banks Spring Research cruise was shortened due to inclement weather.  Dives were conducted at all three banks.  Participants from Texas A&M University (College Station, Galveston, and Corpus Christi) and University of Calgary joined the FGBNMS research team.  Coral recruitment tiles were photographed, maintenance was performed on the recruitment rack, sponge and coral samples were collected for bleaching studies, and general reef observations were made. 

Water temperature ranged from 69F (Stetson) to 73F (Flower Garden Banks). In general, visibility was low - around 30ft at Stetson Bank and 50ft at the Flower Garden Banks.  Seas were 2-4ft on the first day of the cruise, and deteriorated to 5-7ft on the second day, prompting an early departure.

FLOWER GARDEN BANKS LONG TERM MONITORING
M/V SPREE ($20,000)
November 3-5, 2008

G.P. Schmahl and Emma Hickerson participated in the Long Term Monitoring Cruise to the Flower Garden Banks NMS.  Long term photographic data was collected by contractors, PBS&J, at the coral caps of East and West Flower Garden Banks. The Seabird water quality instruments were downloaded and redeployed at all three banks, including Stetson Bank.  Sea conditions were highly variable, with visibility ranging from 35-150ft at East Flower Garden Bank, around 30ft at West Flower Garden Bank, and around 20ft at Stetson Bank.   Water temperature ranged from 74F-77F.  Seas were calm for the first two days of the cruise, deteriorating to 4-7' seas for the last two days. This was the first visit to Stetson Bank since the passage of Hurricane Ike. Significant impacts were observed and photographed.

POST HURRICANE IKE II
M/V MANTA ($5,000)
November 20, 2008

A second cruise was conducted to continue the assessment of impacts due to Hurricane Ike at the Flower Garden Banks National Marine Sanctuary.  Steve Gittings, Emma Hickerson, Jenn DeBose, Tracy Hamburger, and Marissa Nuttall joined the crew of the R/V MANTA and made a comfortable 5-hour run out on the afternoon of November 19th.  Dives were conducted on November 20th at  East and West Flower Garden Bank.  Visibility was around 60’ and water temperature was 75F.  Seas were flat, and no current was encountered. 

Transects documenting damage were conducted from buoys at both banks.  A survey was conducted on the north side of West Flower Garden Bank to determine the condition of the Madracis fields. The fields appear to be intact, with very little damage sustained, unlike the flattened fields at East Flower Garden Bank.  The newly installed u-bolt at East Flower Garden Bank buoy #2 is now, unfortunately, on the bottom side of a very large upturned coral colony. 

Other sightings of note were a loggerhead sea turtle on the surface at WFGB, and a spotted eagle ray at East Flower Garden Bank.  A rotary camera was retrieved for TAMU-CC researchers, Ian MacDonald and Doug Weaver, from East Flower Garden Bank.
