Dr. Darren Rumbold is Director of the Coastal Watershed Institute and Professor of Marine Science at Florida Gulf Coast University where he teaches courses such as Ecological Risk Assessment and Ecotoxicology. He earned a BS and MS in Biology and BA in Chemistry from Florida Atlantic University and completed his Ph.D. in the Department of Marine Biology and Fisheries at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science (RSMAS). Navigating a twisting path to reach FGCU, he now has more than thirty years of experience in environmental science.
He began his career in 1986 as a government scientist monitoring the impact that construction and operation of a solid-waste incinerator and landfill had on a large wading bird rookery (at times >10,000 birds) that was situated next to the West Palm Beach Water Catchment Area. The site also served as a drought-related habitat and the largest roost in the U.S. for the endangered Everglades Snail kite. Besides monitoring their use of the roost/rookery, he initiated a program to biomonitor mercury, dioxin and other potential contaminants from the incinerator. This would begin a long-running interest in mercury. In 1991, he entered the Ph.D. program at RSMAS investigating pesticides and petroleum hydrocarbons along the Florida Keys. His dissertation examined the possibility of toxic materials concentrating in the sea-surface microlayer (SSML). To accomplish this, he developed bioassays using early-life stages of coral reef species. Ultimately, he documented brevetoxin, the toxin from red tides, concentrating in the microlayer. After earning his Ph.D., he took a position assisting Palm Beach County assessing the impact that beach re-nourishment had on sea turtle nesting. He was then awarded an Environmental Science & Engineering Fellowship with U.S. EPA to work at the National Center for Environmental Assessment in Washington, D.C. assessing nutrient fluxes across the air-sea interface fueling harmful algae blooms and its impact on zooplankton. From 1998-2006, he served as Senior- and, later, Lead Scientist with South Florida Water Management District overseeing a program to learn the influential factors controlling mercury biogeochemistry, fate and effects in the Everglades. He also obtained a grant from NOAA to extend this research into Florida bay. During his tenure, he served as Module lead under the Comprehensive Everglades Restoration Plan (CERP) coordinating efforts of state and federal agencies working on mercury. He also served as Technical lead of the Water Quality Team for the Southwest Florida Feasibility Study.
He joined FGCU in 2006 where he uses this diversity of experiences as a teaching-scholar. He mentors students in taking a landscape-scale approach in assessing impacts of high-volume, freshwater discharges and the transport and fate of nutrients, mercury and other toxicants transported through the coastal watershed. He has been a consultant to the CALFED Bay-Delta Program, Maryland Sea Grant College, Tetra Tech EC, Inc., Camp, Dresser & McKee, Inc. and SFWMD. As principal investigator (PI) or co-PI he has secured over $3.5 million in extramural funding. He has authored or co-authored numerous governmental reports (many of which are published on the web), 29 articles in peer-reviewed journals, book chapters and is now co-editing a book on Florida’s mercury problem.
We are examining samples collected in the Florida Keys to study Gambierdiscus, the phytoplankton responsible for producing the toxins that cause CFP. We will analyze how Gambierdiscus populations react to changing seasons, coral bleaching, and storm events, in order to better understand how CFP is related to environmental dynamics. We are also processing algae and fish samples to extract and (semi) purify the toxins to determine how toxin levels are related to changing environmental conditions.
Another team of students is exposing phytoplankton and seagrasses to diluted crude oil to examine how the oil affects their health and growth. These data will then be compared to data collected from field samples to better understand how the Deep Water Horizon oil spill may have impacted these components of the coastal ecosystem in the northern Gulf of Mexico.
We are also studying how well different macroalgae (seaweed) species grow using aquacultured fish waste water, and subsequently how effectively the algae clean the water (remove nutrients) so that it can be recirculated back into the fish tank.

Dr. Jose's recent projects focus primarily on physical ocenaography, coastal circulation modeling, waves, and sediment transport. Previous work has included hydrodynamics and heavy sand transport along south west coast of India, studying the environmental effects of future sand mining from transgressive sand shoals off the Louisiana coast, and natural resources damage assessment from the landfall of Hurricanes Katrina and Rita, by simulating the storm surge and the stranding of salt water in low lying marshes.
Dr. Savarese's research interests span the field of geobiology, combining disciplines from biology and geology to interpret the history of environmental change. His current research programs include the effects of sea-level rise on coastal environmental evolution, the history and paleoecology of reef development, and the effects of environmental change on oyster reef ecology. Michael is very active servicing Southwest Florida’s environmental needs. Over the years he has served on the Board of the Watershed Council, he has been an active member of the Big Cypress Restoration Coordination and the SW FL Regional Restoration Coordination Teams, the SW FL Feasibility Study Team, and the South Golden Gate Estates Restoration Project Delivery Team.
A central theme in much of Dr. Thomas’ research is to determine ecosystem level consequences of natural and anthropogenic stresses in aquatic ecosystems. Dr. Thomas works principally with primary producer communities in shallow marine/freshwater hydrosystems, linking ecosystem structure to physico-chemical variation by understanding functional processes at the base of the food web. His research has combined descriptive and experimental approaches to determine causal relationships between biotic and environmental variation.
We are currently looking at phosphorous retention in Storm Treatment Areas (STA), quantifying & justifying sea grass restoration, studying animals in the benthic zone, as well asthe turbidity, erodibility and sediment dynamics that play a role in the occurrence of brown water along the coast of SWFL.
I am an ecologist interested in describing, protecting, and teaching about the biological diversity and beneficial ecosystem functions of coastal marine habitats. Coastal oceans are simultaneously threatened by decreasing water quality, changing physical conditions, and overharvest of ecologically important species. I address the interactive effects of these threats through conservation-directed research and teaching at Florida Gulf Coast University.
At FGCU I continue my seagrass research, integrating findings from Florida, Virginia, and New England. My scientific approach combines manipulative experiments with observations of spatial and temporal variation in natural communities, and I strongly believe in the complementary natures of experimental and descriptive ecological research.
Dr. Greg Tolley is Professor of Marine Science, Chair of the Department of Marine and Ecological Sciences, and Program Coordinator of the M.S. Environmental Science program at Florida Gulf Coast University. He is also the former Director of Graduate Studies at FGCU.
His current research interests focus on the influence of freshwater inflow on estuarine ecosystems and aquatic resources. Specifically, this research addresses how variation in the timing, amount, and quality of freshwater delivered to estuaries influences the physiology of estuarine organisms, shapes community structure of oyster-reef and zooplankton assemblages, and impacts the potential value of oyster reefs as essential fish habitat. A Certified Fisheries Professional with the American Fisheries Society, Tolley is Acting Director of the Florida District of the American Institute of Fisheries Research Biologists. He has also been active in the local community, having served on the boards of directors of the Calusa Nature Center and Planetarium, the Bailey Matthews Shell Museum, and the Sanibel Captiva Conservation Foundation, and as a member of the Education Committee of the Conservancy of Southwest Florida.
I use molecular ecology approach to investigate my interests in aquatic environments. Since microbes are invisible and many of them are unculturable, this approach perfectly matches my needs. Tracking down of nucleic acids in environments, sometimes it is called environmental DNA (eDNA), can be also used in various study settings, particularly in the study of endangered species and invasive species.

Dr. Muller is working on a project that will reconstruct the hurricane history of Southwest Florida over the past five thousand years by identifying hurricane overwash deposits in back-barrier lagoons and marshes. Records will be correlated with existing paleotempestological studies to determine patterns of hurricane activity and inactivity. To understand how the El Niño Southern Oscillation (ENSO) and sea surface temperatures (SSTs) have impacted hurricane activity in the past, correlations will be made with previously published paleo-ENSO and paleo-SST studies. In addition, the study will establish a site-specific Southwest Florida hurricane database that will be used to better understand the characteristics of storms that produce overwash deposits.

Estero River Bacteria-Nutrient Source IdentificationThis research is designed to identify, characterize, determine sources, and to the extent possible, quantify loads of bacteria and nutrients in the Estero River.
Quantifying the Water Quality Benefits of SAV RestorationThis project will quantify the nutrient removal capacity of submerged aquatic vegetation (SAV) in the CHNEP area.

Estero River Bacteria-Nutrient Source Identification
Donald Duke, Ph.D., P.E.
Serge Thomas, Ph.D.
Hidetoshi Urakawa, Ph.D.
This research is designed to identify, characterize, determine sources, and to the extent possible, quantify loads of bacteria and nutrients in the Estero River, with particular attention to detecting and quantifying sources in a reach of the river believed to be impacted.
The research will conduct field sampling over one year to characterize bacteria and nitrogen during wet and dry season, to attempt to differentiate the ways in which bacteria and nutrients originate and are mobilized. Dry season flow originates largely as discharge of surficial groundwater, and wet season flow includes both increased surficial groundwater discharge (as water table rises during that season) and surface runoff. During the wet season the project will conduct monitoring that will distinguish loads in runoff from storm events (which would suggest sources in leaking waste conveyances and/or in surface land use activities) vs those carried in sustained flow during wet season (which would suggest soil and sediment sources). In addition, sediment, riverbank soil and plant samples will be corrected to identify the potential source of microbial contamination.
Samples will be tested for two groups of bacteria: Enterococcus because it is the target organism for marine water quality standards; and Escherichia coli to capture any variation. Testing for two species is recommended because the literature shows that any single indicator can be inconsistent and can miss bacteria sources/loads. Test also for nitrogen species as a means to characterize load, and because nitrogen compounds (especially ammonia) can be linked to the kinds of sources investigated here, i.e. human waste and sources of bacteria potentially growing in soils and sediments. Test a portion of these using genetic sequencing to characterize the proportion originating with humans vs. other organisms. Conducted for only a portion of the samples because a subset will be sufficient to indicate which organism(s) are the major origins of bacteria to this waterbody. Test a portion of these samples for indicators of wastes from human origin: acetaminophen and sucralose.
Quantifying the Water Quality Benefits of SAV Restoration
James Douglass, Ph.D.
Win Everham, Ph.D.
David Ceilley, M.S. CSE (Johnson Engineering)
This project will quantify the nutrient removal capacity of submerged aquatic vegetation (SAV) in the CHNEP area. It will focus on tapegrass (Vallisneria americana), a species native to the area and historically abundant in freshwater and low-salinity estuarine habitats. This project has direct applications for evaluating the effectiveness of SAV for nutrient removal in stormwater treatment systems, canals, and natural water bodies. It also has implications for NPDES permit compliance, BMAPs, and wet detention pond design BMPs. The project links with the Citizen Seagrass Gardening project implemented in 2018 to inform the public and involve citizens in using personal BMPs in local waterways.
The three objectives of the project are:
1. Determine nutrient removal rates for the SAV species Vallisneria americana in the Southwest Florida environment.
2. Quantify the total nutrient removal achieved by the large scale Vallisneria americana restoration effort currently underway in the Caloosahatchee Estuary by combining the nutrient removal rate information with data on the extent of habitat restored.
3. Provide the public with an easily-cited statistic for SAV nutrient removal. It will be analogous the widely-cited statistics for oyster filtration rates that have been used to successfully bolster support for oyster restoration projects. This should increase public interest in SAV restoration and conservation, particularly in waterways and along shorelines of developed areas, e.g., in stormwater conveyances, wet detention ponds, and canals where the ecosystem services of vegetation tend to be underappreciated.
Mercury and the Everglades, Vol. I

From Mercury and the Everglades Vol. 1, The Evolution of the Everglades as a Perturbed Ecosystem and the Role of Atmospheric Mercury:
"This book integrates 30 years of mercury research on the Florida Everglades to inform scientists and policy makers. The Everglades is an iconic ecosystem by virtue of its expanse; diversity of biota; and multiple international designations. Despite this, the Everglades has been subjected to multiple threats including: habitat loss, hydrologic alterations, invasive species; and altered water quality. Less well recognized as a threat to Everglades human use and wildlife populations is the toxic metal, mercury. This Volume focuses on sources of mercury to the Everglades from the late-1980’s when there was bewilderment as to why there were very high levels of mercury in the Everglades food web. Soon came the finding that mercury loadings from atmospheric deposition accounted for over 95% of total input to the Everglades which resulted in Florida conducting the most comprehensive mercury monitoring and modeling study performed to date. Topics discussed in this Volume include: (1) Why atmospheric deposition fluxes of mercury to the Everglades are amongst the highest in the U.S; (2) That these are overwhelmingly from sources outside of the U.S; (3) That mitigation strategies for resolving the elevated food web mercury problem in the Everglades that rely solely on reducing atmospheric mercury inputs will not be effective for many decades; (4) That consideration of other strategies, in particular controlling factors related to Everglades mercury biogeochemical cycling seem warranted."
