Fact Sheets Sea Grant Releases Boater’s Guide on Handling Oil and Fuel Spills Brochure for boater

The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce a new Sea Grant informational brochure just in time for the summer boating season. The one-page guide gives boaters information on how to prepare for, respond to, and report an accidental oil or fuel spill on their vessels. A Boater’s Guide to Handling Oil and Read More

Environmental stressors can cause changes in the abundance and location of certain marine mammal species, which can affect future populations. Researchers can track marine mammals using the number of vocalizations or clicks picked up by acoustic monitoring systems, which can provide insights into their recovery from environmental stressors and, more broadly, deep-water ecosystem health.

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 Read More

Scientists analyzed sediment cores from two sites near the Macondo wellhead to characterize possible spill impacts on benthic foraminifera (single celled organisms with a hard shell). The team found elevated Polycyclic Aromatic Hydrocarbon (PAH) concentrations and a significant decrease in density and species diversity for foraminifera. The first signs of benthic recovery took about 1 Read More
