2021: Geospatial distribution of hypoxia associated with a Karenia brevis bloom
In 2018, the presence of bottom water hypoxia along the SW Florida coast was investigated during a bloom of the toxic dinoflagellate Karenia brevis. The bloom was first detected in…
Read MoreNitrogen-enriched discharges from a highly managed watershed intensify red tide (Karenia brevis) blooms in southwest Florida
Karenia brevis blooms on Florida’s Gulf Coast severely affect regional ecosystems, coastal economies, and public health, and formulating effective management and policy strategies to address these blooms requires an advanced…
Read MoreAlgal blooms in a river-dominated estuary and nearshore region of Florida, USA: The influence of regulated discharges from water control structures on hydrology and nutrient conditions
Flow-regulated discharges of water from control structures into estuaries result in hydrologic and water chemistry conditions that impact spatial and temporal variability in the structure and biomass of phytoplankton communities,…
Read MoreDownstream nutrient concentrations depend on watershed inputs more than reservoir releases in a highly engineered watershed
In this study, we characterized the impact of regulatory water releases relative to watershed inputs on the quality of receiving waters to identify if and how managed releases could be…

Evaluation of bacteriological and nutrient concerns in nearshore waters of a barrier island in SW Florida
To determine if local onsite treatment systems affect nearshore water quality, seasonal and rain event monitoring of bacteria and nitrogen was conducted on the Gulf and estuary sides of Captiva…
Read MoreLocal and regional effects of reopening a tidal inlet on estuarine water quality, seagrass habitat, and fish assemblages
Blind Pass is an inlet that separates Sanibel and Captiva Islands in southwest Florida but has historically closed and opened by both anthropogenic and natural processes. In July 2010, a…
Read MoreTesting anti-fouling coatings with special emphasis on coastal observing systems
Biological fouling is the accumulation and growth of aquatic organisms on submerged surfaces. Fouling can reduce the operation time and quality of data from aquatic real-time sensors. The SCCF Marine…
Read MoreEvaluating light attenuation and low salinity in the lower estuary with RECON (River, Estuary, and Coastal Observing Network)
The southern portion of the Charlotte Harbor region, which includes Pine Island Sound, San Carlos Bay, and the lower Caloosahatchee Estuary, has over 11,700 ha of submerged aquatic vegetation (SAV).…
Read MoreHydrogen peroxide measurements in subtropical aquatic systems and their implications for cyanobacterial blooms
Hydrogen peroxide is widely recognized as the most stable of the reactive oxygen species (ROS) produced by both biotic and abiotic pathways in natural waters. Its high reactivity in mediating…
