CORAL SPAWNING CRUISE 2014
Two-toned blue dashed line

August 15-17, 2014
aboard the R/V MANTA

Overview

The sanctuary research team, along with scientists from Oregon State University and the University of Texas at Austin, traveled to the sanctuary to study and document the annual mass coral spawning of its reefs.

The event occurred as predicted, with some spawning taking place on the seventh night after the August full moon (Saturday, Aug. 16), and the majority taking place the following night. Witnesses to this year's event described the spawning event as less prolific than years past.  

Researchers also collected spawn and coral fragments to study genetics, thermal tolerance, and fluorescence in corals. These acitivities were accomplished under a sanctuary research permit.

The collected fragments were stored in tubs on the top deck of R/V MANTA for observation.

Researchers watched the coral fragments at spawning time using red lights so as not to 'disturb' the corals. This allowed for night time conditions, but provided enough light for the researchers to complete their tasks.

The coral fragments spawned on cue, in tubs on the top deck of R/V Manta, while the vessel was docked at Texas A&M Galveston at the end of the trip.

Daytime Activities

A sampling carousel was used to measure temperature and salinity to 200 feet near one of the TABS (Texas Automated Buoy System) buoys near East Flower Garden Bank.

Water quality instruments were also downloaded and serviced. This instrument is used to measure temperature and salinity at the reef crest. One is deployed at each bank within the sanctuary. They require quarterly maintenance and downloading.

Placozoa recruitment plates were installed at various locations around the reef as part of a TAMUG project.
