Peatlands contain a significant amount of the global soil carbon, but the climate feedback affecting carbon stability within these peatland systems is still relatively unknown. Organic matter composition of peatlands plays a major role...
Peatlands cover a small percentage of the earth surface, but the exact mechanisms of how a third of the Earths global soil carbon is sequestered is not yet resolved. Therefore, this thesis aims to explore the relationship between the...
Climate change is radically altering the Arctic. These alterations are expected to have immense and cascading implications on the carbon cycling of the region. In particular, our interest lies in the Kolyma River (KR) as it is the...
Rivers deliver approximately 260 Tg of dissolved organic carbon (DOC) to the ocean annually, yet there is little evidence of terrigenous DOC (tDOC) in the ocean. While tDOC was historically believed to be stable and resistant to...
After the Deepwater Horizon (DWH) blowout, MC252 crude oil was washed onto the shores of the northeastern Gulf of Mexico. Weathered oil was buried in sandy Florida beaches in the form of sands covered by oil films, small oil particles, ...
Trace gas analysis in Earth systems plays an important role in planetary research. Bernard (1976) and Whiticar (1999) proposed that biologically produced methane and thermogenically or geologically produced methane could be...
Karenia brevis is a marine dinoflagellate commonly found in the Gulf of Mexico and important both ecologically and economically due to its production of the neurotoxin brevetoxin, which can cause respiratory illness in humans and...
Despite being a known benthic biological hotspot and environmental ecotone, the DeSoto Canyon has hardly been characterized for its benthic diversity and community structure. Moreover, it is a known deposition and impact zone due to...
The Deepwater Horizon (DWH) blowout of 2010 released an estimated 4.5-4.9 million barrels of oil and 500, 000t of methane into the Gulf of Mexico (GOM). Some of this oil rose to the surface, forming oil slicks, while an estimated 30% of...
The Deepwater Horizon (DwH) blowout released 5.0x1011g C from gaseous hydrocarbon into the water column and up to 6.0x1011g C from oil (Joye et al., 2011). Oil was visible on the surface, but <0.01% of the gaseous hydrocarbon escaped the...
Climate change is melting glaciers and altering watershed biogeochemistry across the globe, particularly in regions dominated by mountain glaciers, such as southeast Alaska. Glacier dominated watersheds exhibit distinct dissolved organic...
Ecophysiological Responses of Phytoplankton to Environmental Cues - A Laboratory Approach: Effects of Growth Light Quality on Phytoplankton and an Assessment of Carbon Utilization in Karenia Brevis
Phytoplankton are primary producers in the marine food web, providing energy and matter for higher trophic levels by fixing CO2 and inorganic nutrients into biomass. This production of particulate organic matter by marine phytoplankton, ...
