Researchers analyzed dissolved organic carbon from water column samples collected in five regions to establish baseline data about its relative persistence and cycling in the northern Gulf of Mexico. The team found that the Mississippi River exports large amounts of dissolved organic carbon with an anthropogenic 14C signature, which is removed and recycled offshore as the river plume moves offshore.
Crude oil contains tens of thousands of hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs) that create unique chemical fingerprints for different types of oil. Dawei “David” Shi uses geochemical analysis techniques in mesocosm studies to track these fingerprints.
Laser light and high-speed cameras can help researchers observe the behavior of oil droplets within a laboratory-simulated oil plume and interpret how the oil subsequently may move through the water column. Xinzhi Xue uses lasers to non-invasively probe inside the oil plume and get a detailed look at the oil fragmentation process.
An international science team conducted a tidal-cycle study across a Destin, Florida inlet to better understand currents and the transport of dissolved and suspended materials between an estuary and the coastal ocean.
Scientists measured the natural abundance of radiocarbon (14C) in sediments near the Deepwater Horizon spill site and estimated the location and amount of carbon derived from crude oil or gas.
Modeling Study Suggests Dispersants Used at Wellhead had Marginal Effect on Oil Reaching Surface Waters
Scientists studying the use of sub-sea chemical dispersants during the Deepwater Horizon spill published their recent findings.
The natural microbial community in the water column and on the sea floor of the northern Gulf of Mexico (GOM) surprised the watching world in the aftermath of the Deepwater Horizon Oil Spill (DHOS) by quickly working to help mitigate the effects of the oil.
Up to $22.5 million will be awarded to researchers studying the effects of the Deepwater Horizon incident on the Gulf of Mexico, public health.
I am currently looking for a Postdoctoral associate who will collaborate in a multi-institution, interdisciplinary project to quantify the physical, chemical, and biological mechanisms that redistribute hydrocarbons from the benthos to the water column in the Gulf of Mexico, as contribution to the Gulf Research Initiative.
