Name of New Research Vessel Honors Dr. William Hogarth

The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce that a new state-of-the-art scientific research vessel has been named in honor of Research Board member William “Bill” T. Hogarth. The R/V W.T Hogarth will support the research of over two dozen institutions and agencies across Florida and will be used for refined bottom mapping, metal tracing, surveying, collecting samples, and more.

Study Identifies Oil Carbons Associated with Deepwater Horizon in Terrestrial Birds

Scientists analyzed the carbon composition in Seaside Sparrow tissues to learn if oil from the 2010 spill was incorporated into the terrestrial food web. The researchers found reduced radiocarbon and stable carbon concentration levels in the feathers of birds captured at oiled sites compared with birds from non-oiled sites, which is consistent with a fossil oil source.

Grad Student Mahmud Makes Acoustics and Tracking Marine Mammals “Click”

Sakib Mahmud tests combinations of passive acoustic monitoring equipment to find the best method to detect and measure marine mammal populations affected by the Deepwater Horizon oil spill. His findings will help improve our understanding of long-term environmental impacts of the spill on deep-diving marine mammals and aid in improving oil spill regulations, monitoring, and mitigation efforts.

Grad Student Morales-McDevitt Explores How Nutrients Influence Marine Snow Formation

Marine oil snow is the largest commuter of carbon to the seafloor and occurs when oil and marine particles aggregate and sink through the water column. Previous studies show that oil and dispersant significantly increased marine microorganisms’ production of exopolymeric substances (EPS), an extremely sticky goo that holds marine snow together. Maya Morales-McDevitt conducts mesocosm experiments investigating how certain naturally occurring nutrients influence EPS production and oil degradation.

Smithsonian Highlights Oil Spill Research on Mahi Mahi

The Smithsonian recently published an article about research, funded by the Gulf of Mexico Research Initiative (GoMRI), that investigates oil spill impacts on different life stages of mahi mahi. Highlights include what is involved in conducting this cutting-edge research, what is being discovered about mahi mahi that is not oil-spill related, and the multiple scientific perspectives that help develop a comprehensive understanding of these important fish.
