Significant coral reef community development exists along the eastern shelf of the United States from the Dry Tortugas through the Florida Keys (Monroe County) and Southeast (SE) Florida (Miami-Dade, Broward, Palm Beach, and Martin Counties). State and county resource managers have partnered with academia to monitor the health of the SE Florida reef system. Since 2000, more than 20 sites have been monitored annually offshore Broward County. Quantitative data includes stony coral species cover, colony size, density, and condition (bleaching, disease, etc.) and gorgonian and sponge density. The SE Florida Coral Reef Evaluation and Monitoring Project (SECREMP) was established in …

A bathymetric survey was recently conducted in Southeast Florida (Broward County) during April 2001 using the Laser Airborne Depth Sounder (LADS) system. This four-meter resolution survey encompassed from North Dade County, through the length of Broward County coastline, to south Palm Beach County (approximately 43 km) and from the shore eastward to depths of approximately 40 m (2.5-3.5 km offshore). This georeferenced data was sun shaded at various angles and azimuths and draped with a NOAA NAPP 1:24,000 georeferenced air photograph mosaic. The model was zoomed and tipped to the desired orientations and processed into three-dimensional perspectives. Two views, slightly …

Benthic assemblages of variable density cover three progressively deeper ridges that parallel the Broward County, Florida, coast. An acoustic bottom classification survey using QTCView5 with a 50 kHz transducer showed different acoustic classes on the shallow reef-ridge and the two deeper reef-lines, which both showed the same acoustic signature. Ground-truthing showed that the differences in acoustic signature corresponded to different benthic assemblages: nearshore hardgrounds had low live cover and were dominated by algae covering substrate, the two deeper reef-ridges had the same acoustic signature and similar benthic assemblages (dominated by sponges and gorgonians). The QTCView5 was also able to differentiate …

As part of an ongoing study of coral bleaching, observations were made of corals on reefs (ca. 8m) off John U. Lloyd Beach, Dania, FL, in December, 1987. Bleaching was evident in approximately 50% of Montastrea annularis, the dominant scleractinian coral species. Quantitative pigment measurements by HPLC show that bleached corals contained

Montastrea annularis heads were collected near Negril, Jamaica, along transects from open, normal reef conditions into the mouths of rivers draining the Negril Morass. Corals subject to turbidity (particulate peat and dissolved humic compouonds near rivers, re-suspended reef sediments away from them) were growing more slowly than those in normal circumstances. Surprisingly, corals growing fastest were slowing the most, and the slowest growers increasing growth rate. Linear regression analysis of growth trends over the past two decades revealed stable limit-cycle behavior: change of growth was inversely proportional to growth rate, with a very significant correlation coefficient of -0.92. We suggest …
