2019 Flower Garden Banks National Marine Sanctuary Long-Term Monitoring of the Reef Crest and Mesophotic Benthic and Fish Communities of Stetson Bank, northwestern Gulf of Mexico (NCEI Accession 0294276)

Metadata Updated: November 1, 2025

This dataset contains raw and processed data from an annual long-term monitoring study that documents the benthic and fish community changes at Stetson Bank, in the Flower Garden Banks National Marine Sanctuary. Bank crest monitoring includes random transect and repetitive photostation photographs of the benthos to estimate percent cover of major taxonomic groups (e.g., coral, sponge, algae). Benthic photographs are analyzed using Coral Point Count (CPCe) and output into Microsoft Excel worksheets. Fish census surveys are conducted annually using a modified Bohnsack and Bannerot stationary method, both at random and repetitive sites. Fish data are recorded in Microsoft Excel worksheets.

Water quality parameters (e.g., temperature, salinity, turbidity, nutrients) are measured with moored conductivity temperature depth (CTD) instruments and quarterly profiles of the water column are performed. Temperature and salinity data are reduced to report daily averages. In 2015, monitoring efforts were expanded to include the deeper mesophotic habitat (34-64 m) surrounding the bank crest using a remotely operated vehicle (ROV).

Mesophotic monitoring includes random transect and repetitive photostation photographs of the benthos to estimate percent cover of major taxonomic groups (e.g., coral, sponge, algae). Repetitive photostation images are only assessed using qualitative summaries of key species identified in 2015 during installation. Random transect photographs are analyzed using Coral Point Count (CPCe) and output into Microsoft Excel worksheets. Fish census surveys are conducted annually in conjunction with benthic transect surveys. Fish data are recorded in Microsoft Excel worksheets. The bank crest benthic community at Stetson Bank has undergone several significant shifts, changing from a habitat predominated by hydrocoral and sponges to one of macroalgae and sponges. The fish community on the bank crest has varied annually. Exotic fish species are present at the bank, including lionfish (Pterois volitans/P. miles) and regal demoiselle (Neopomacentrus cyanomos). Fluctuations in oceanic conditions, macroalgae cover, and continued annual variation in fish communities were documented.
