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.

Science at Sea: Researchers Monitor Marine Ecosystems Near Deepwater Horizon

A 12-day science expedition on the exploration vessel Ocean Intervention II embarks June 11 to investigate how oil, gas, and chemical dispersants affect marine life and their environment deep in the Gulf of Mexico. Scientists and outreach personnel onboard the vessel will interact with the public and school-age children using streaming video, social media, and question-and-answer sessions.

Marine Researchers Engage Fishing Communities to Improve Trust in Science

Trust in scientific findings is especially important when the research relates to your livelihood and health as it did for commercial and recreational fishing communities after the Deepwater Horizon oil spill. Many scientists conducting early studies on the spill believed that they were considered trustworthy, like firemen and policemen. However, it became apparent as the spill unfolded that the relationship of the public, science, and trust was complex and sometimes on shaky ground.

“Drifting in the Gulf” Video Depicts the Trials and Errors of Designing the Perfect Drifter

The Deepwater Horizon event highlighted the need for more economical and ecofriendly methods to accurately track and study ocean currents. Scientists with the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment II (CARTHE II) spent two years testing different structures and materials to develop a practical, cost-efficient, and biodegradable drifter design.
