Book Description
This report summarizes fish and benthic community observations and water quality data collected from East Flower Garden Bank and West Flower Garden Bank long-term monitoring study sites in 2016. East Flower Garden Bank and West Flower Garden Bank are part of the Flower Garden Banks National Marine Sanctuary and located in the northwestern Gulf of Mexico. The annual long-term monitoring program officially began in 1989, and is funded by NOAA's Flower Garden Banks National Marine Sanctuary, the Bureau of Ocean Energy Management, and the National Marine Sanctuary Foundation. In 2016, mean coral cover was 49.92% within the East Flower Garden Bank study site and 58.54% within the West Flower Garden Bank study site. Mean macroalgae cover was 37.15% within the East Flower Garden Bank study site and 25.69% within the West Flower Garden Bank study site. Percent coral cover within repetitive study site photostations and at deep repetitive photostations ranged from 60-75%. The Orbicella species complex, listed as threatened under the Endangered Species Act, accounted for the majority of the coral cover within the study sites. Fish surveys conducted in 2016 indicated an abundant and diverse reef fish community, predominated by Labridae and Pomacentridae families. Water column temperatures warmed quickly in 2016, leading to the most severe coral bleaching event recorded at both banks. A localized mortality event was also documented and studied at East Flower Garden Bank. Decreased salinity, high temperatures, and low oxygen levels may have been contributing factors to the event. Bleached corals recovered after water temperatures dropped below threshold levels.

Book Description
"Since 1989 a federally supported long-term coral reef monitoring program has focused on two study sites atop East Flower Garden Bank and West Flower Garden Bank (EFGB and WFGB) in the northwestern Gulf of Mexico. In 27 years of continuous monitoring, mean coral cover was above 50% and represented a stable coral community. Despite global coral reef decline in recent decades, EFGB and WFGB have suffered minimally from hurricanes, coral bleaching, and disease, and the reef supports relatively diverse and abundant benthic and fish populations. This report summarizes fish and benthic community observations and water quality data from 2015 as part of the annual long-term monitoring program jointly funded by NOAA’s Flower Garden Banks National Marine Sanctuary and the Bureau of Ocean Energy Management. The benthic and fish community surveys were conducted by a team of multi-disciplinary scientists using random transects to document components of benthic cover, repetitive photostations to document changes in the composition of benthic assemblages in shallow and deep repetitive sites, and modified Bohnsack and Bannerot (1986) fish surveys to examine fish population composition within designated study sites at EFGB and WFGB"--Executive Summary.

Book Description
The Flower Garden Banks, remotely located topographic features on the continental shelf in the Gulf of Mexico, are afforded a certain measure of natural protection due to their geographic distance from land. Problems that affect coral reefs throughout the region, including land-based sources of pollution, overfishing, and coral disease have, to date, not had a measurable effect at the Flower Garden Banks. In addition to their relative isolation, the depth of these reefs, 18-48 m, has protected the corals from severe bleaching events that have had devastating effects on most western Atlantic reefs. Although coral disease has been identified at the Flower Garden Banks, the incidence and prevalence have been low compared to other sites within the western Atlantic reef-building province.
