A large fraction of the continental shelf is covered by permeable sediments that are flushed by wave, wind, and tide generated bottom currents. Elevated dissolved organic carbon (DOC) concentrations in coastal zones, a diverse and...
The deep-sea, soft-bottom habitat is considered the largest ecosystem on Earth, yet little is known about the biogeography of the infauna. This dissertation examines the species' ranges of the meiofaunal taxon Harpacticoida (Crustacea:...
The Effective Reduction of Methane Emissions from Landfills Using a Biocover Approach: Measuring Methane Oxidation Using Static Chamber and Stable Isotope Techniques
Adding mulch to a landfill clay cover is a cost effective way to mitigate methane emissions from landfills. This was determined by setting up 3 plots (18x32m) at the Leon County landfill. Two bio-covers consisted of a 15-20 cm thick...
The Field Research Center (FRC) in Oak Ridge, TN, was established by the U.S. Department of Energy's Natural and Accelerated Bioremediation Research (NABIR) Program to develop strategies for bioremediation of contaminant metals and...
Prior to 1999, the harpacticoid copepod species Zausodes arenicolus had been considered to be very useful for ecological studies because its unusual shape made it easy to recognize. Bouck et al.'s (1999) taxonomic revision based on an...
The Tongue of the Ocean (TOTO) region located within the Bahamas archipelago is a relatively under-studied region in terms of both its biological and physical oceanographic characteristics. This region is comprised of a deep trough along...
Large portions of the world ocean are less productive than they should be based on their nutrient concentrations. Dubbed high-nutrient low-chlorophyll (HNLC) regions, primary productivity in these areas may be limited by any number of...
The growth of a locally isolated strain of green algae, Chlorella sp., selected for its promise as a biodiesel feedstock, was studied in wastewater effluent from the municipal wastewater treatment plant in Tallahassee FL. Nutrient...
In the uppermost millimeters of shallow marine sands, photosynthesis by microalgae can cause oxygen supersaturation, leading to formation of oxygen bubbles and subsequent ebullition of the gas from the sediment. The role of ebullition...
Low oxygen conditions in the water column or hypoxia occur in estuaries and impact more than just the obvious commercially important species. Copepods are an important link in the food web and the influence of hypoxia upon them is...
Denitrification in coastal sediments is a process of significant scientific interest and a major concern in coastal management. Reliable estimates of denitrification in coastal ecosystems are unavailable due in large part to a lack of...
I investigated the emergence of marine benthic harpacticoid and cyclopoid copepods from subtidal sediment into the bottom water. Previous field studies with traps found that copepods emerge from the sediment within 2 h of dusk. I...
Mariculture of fish is needed to support our ever growing global population. Copepods are a natural and beneficial source of first feed for many marine fish species, but it can be difficult to hatch enough when the fish are ready to feed...
Apalachicola Bay is a productive estuary located in the northern Gulf of Mexico. The high productivity is, in part, the result of the Apalachicola River delivering freshwater and nutrients to the Bay. Nutrient input supports high levels...
Northern peatlands are complex wetland ecosystems that are characterized as bogs, fens, or tundra. Since these systems are flooded for much of the growing season, organic matter often decomposes anaerobically. Methanogenesis is the...
