Long-Term Monitoring at the East and West Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico, 2007-2008 (NCEI Accession 0070125)

The data included in this accession are: (1) random transect data (i.e., percent cover of benthic components) obtained from videography (2007 and 2008); (2) sclerochronology data calculated from 2007 cores, showing short-term coral growth rates; (3) lateral growth/recession of marked Diploria strigosa colony margins calculated from annual photographs (2006-2007); (4) percent cover of benthic components and coverage of coral bleaching, paling, fish biting, and disease (2007 and 2008) and planimetry data (gain/loss in area of specific coral colonies from 2006-2007 and 2007-2008) acquired from repetitive 8m2 quadrat photographs; (5) water quality data recorded on YSI datasondes, Sea-Bird SBE 37-SMP MicroCAT, and Hobotemp thermographs and water chemistry results including nutrients (2006-2008); and (6) annual fish population surveys to monitor species abundance and size over time (2007).

Statistical analyses, photographs, and videography are not included in this submission. Photographs and video collected during the 2007 and 2008 monitoring events were placed on DVD and sent to NODC via mail. These photographs and videos were placed in individual folders within this accession.

The purpose of these biological and oceanographic data is to serve as a long-term record of the conditions of the coral reef communities within the Flower Garden Banks study sites. BOEMRE and NOAA continue environmental monitoring for continuity of data and for generating information needed for resource management and regulatory decision-making. In addition, the monitoring data are needed to validate and sustain the present understanding of BOEMRE lease stipulations for providing effective mitigation of impacts to the offshore environment.
