Long-Term Monitoring at the East and West Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico, 2002-2006 (NCEI Accession 0012632)
The Long-Term Monitoring at the East and West Flower Garden Banks National Marine Sanctuary 2002-2006 data include biological and oceanographic measurements collected to satisfy the MMS and NOAA contracts 1435-01-02-CT-85088 and 1435-01-04-CT-33137 through the monitoring year 2006. The Flower Garden Banks are located in the northwest Gulf of Mexico and are unique within the region. The Flower Garden Banks are coral reefs with biological assemblages typical of Caribbean coral reefs, including approximately 23 Caribbean scleractinian coral species, a low abundance and diversity of sponges, and reef fishes. These data are the result of yearly monitoring events and are used for comparison purposes required to complete technical reports and presentations. Statistical analyses, photographs, and videography are not included in this submission. On the East and West Flower Garden Banks there are 100 m by 100m study sites within which monitoring is conducted every year. The data included in this submission are from these study sites and include the following: (1) random transect benthic cover data obtained using videography (2002-2006), still photographs (2002-2003) and linear point intercept observer data (2002-2003). Random transect data include the proportional cover of benthic components including coral species, sponges, algae, and other groups. (2) Sclerochronology data are taken during odd years to look at short-term (10 years) change in coral growth rates. (3) Photographs of marked Diploria strigosa colony margins are taken annually to track lateral growth or recession of colony margins over time. Data within this dataset start with comparisons between 2001 and 2002. (4) Repetitive 8m2 quadrat planimetry data follow specific coral colonies over time. Coral colonies are traced each year to measure lateral growth, loss, and/or replacement within a continuously monitored 8m2 area. Data within this dataset start with comparisons between 2001 and 2002. (5) Abiotic water quality parameters are recorded on a continual basis using YSI datasondes. Data include temperature, specific conductivity, dissolved oxygen concentration, dissolved oxygen charge, pressure, depth, pH, pHmV, par1, par2, turbidity, and salinity. Additionally, HoboTemp thermographs are used as a back-up to record temperature. On YSI datasonde changeout cruises water samples are taken at surface, mid-water and at the benthos for nutrient and chlorophyll analysis. (6) Fish population surveys are completed to monitor fish species abundance and size from year to year.

Supplemental Information | Data purpose: The Long-Term Monitoring at the East and West Flower Garden Banks National Marine Sanctuary 2002-2006 data include biological and oceanographic data collected to satisfy the MMS and NOAA contracts 1435-01-02-CT-85088 and 1435-01-04-CT-33137 through the year 2006. 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 East and West Flower Garden Banks study sites. MMS 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 MMS lease stipulations for providing effective mitigation of impacts to the offshore environment. Parameters: Random transects: Percent cover of corals identified to species, sponges were combined into a single group or identified to species when possible, macroalgae identified to species when possible, or categorized as a group, and included anything longer than approximately 3mm. Crustose coralline algae, fine turfs and bare rock were grouped as CTB (crustose coralline, turf, and bare). Additional categories included other live, sand and rubble, and unknown. Sclerochronology: Annual growth bands, as measured from high density band to high density band in a longitudinally sectioned core. Lateral growth of Diploria strigosa colonies: area of coral head (cm2). Repetitive 8 m2 quadrats: area of coral head (cm2); percent cover of corals identified to species, sponges were combined into a single group or identified to species when possible, macroalgae were identified to species when possible and included anything longer than approximately 3mm. Crustose coralline algae, fine turfs and bare rock were grouped as CTB (crustose coralline, turf, and bare). Water quality: Temperature, specific conductivity, dissolved oxygen concentration, dissolved oxygen charge, pressure, depth, pH, pHmV, par1, par2, turbidity, and salinity. Fish data: fish species, number of individuals observed, minimum fish length observed (cm), maximum fish length observed (cm), mean fish length (cm). File organization description: The files submitted to NODC are organized according to each monitoring period. A single file contains all data pertaining to the monitoring events of 2001-2003. The data collected during the 2004-2005 period is separated into several, separate files due to the large file size. The 2004-2005 data consists of four parts. The first part includes random transect data, sclerochronology, Diploria strigosa lateral growth, and repetitive quadrat planimetry data. The second and third parts include all water quality data from the East and West Flower Garden Banks between 2004 and 2005. The final part, part 4, includes the fish survey data from both the East and West Flower Garden Banks. The data collected during the post hurricane assessment cruise in November 2005 at the East Flower Garden Bank is attached as its own file. The data collected during the June 2006 cruise is also attached as its own file. |
