Study Finds UV Exposure Late in Mahi-Mahi Embryo Development Enhances Oil Toxicity

Researchers conducted laboratory experiments on mahi-mahi embryos to determine the effects of ultraviolet radiation (UV) and oil co-exposure during different times in their development. The team observed that UV affected the success of mahi-mahi hatch in all exposure scenarios compared to controls but was highest (a 1.6- to 6-fold increase) when co-exposure occurred late in embryonic development.

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.
