GoMRI ScientistsResearch Stories Understanding Oil Transport in Coastal Waters Understanding Oil Transport

CONCORDE studies sub-surface exposure pathways After the Deepwater Horizon incident, the coastline oiling that occurred raised questions about oil movement and impact. For example, before a surface slick reached land, was there oil below the surface waters and how might that affect coastal environments and organisms? The Gulf of Mexico Research Initiative recently awarded CONCORDE Read More

GoMRI ScientistsResearch Stories Smithsonian Highlights Oil Spill Research on Jellyfish Jellyfish_1318

Jellyfish push water in and out of their bells to propel themselves forward. Researchers are investigating if and how the small underwater waves and currents created by Jellyfish movements can help break up oil spilled in marine ecosystems. The Smithsonian posted an article featuring scientist Brad Gemmell’s research about interactions of gelatinous zooplankton with oil. Read More

Phytoplankton are active organic carbon producers and help drive the processes that move carbon from the ocean surface to the sea floor. Scientists are investigating impacts from the sudden large input of carbon from the Deepwater Horizon spill on this important biological cycle. The Smithsonian Ocean Portal recently featured Uta Passow with the University of Read More

During the Deepwater Horizon incident, both oil and methane entered the surrounding marine environment from the Macondo reservoir. Scientists are investigating the released methane’s effects on deep-sea ecosystems. The Smithsonian published a story featuring the work of three GoMRI scientists – Samantha Joye, Jeff Chanton, and Frank Hernandez – who are examining microbes that feed on Read More

GoMRI ScientistsResearch StoriesVideo and Podcasts Tracking Marine Mammal Recovery after the Deepwater Horizon Oil Spill LADC-GEMM

LADC-GEMM studies acoustic signals in spill vicinityDid whale and dolphin populations change after the oil spill? Prior monitoring indicated that large numbers of these deep-diving marine mammals were living near the Deepwater Horizon site. The Gulf of Mexico Research Initiative recently awarded the LADC-GEMM consortium a grant to study endangered sperm whales, beaked whales, and Read More

Citizen ScienceGoMRI Scientists A Match Made in Florida: Citizens and Scientists Team Up for Research and Education 2138a

What do CARTHE, the International SeaKeepers Society, and Fleet Miami have in common? Ocean research! Last September, CARTHE researchers from the University of Miami Rosenstiel School partnered with SeaKeepers and Fleet Miami to widen the reach of ocean and oil spill research in the local community. The alliance led a three-day expedition aboard a 54-foot Read More

GoMRI ScientistsVideo and Podcasts Perspectives from the GoMRI Research Board Perspectives of GoMRI Research Board

BP put in place $500 million for research shortly after the Deepwater Horizon oil spill to understand the impacts from this incident and improve response to future events. But it would take much more than money to establish an independent research program that fulfills the highest scientific standards and meets the needs of various stakeholders. Read More

GoMRI Scientists Louisiana Scientists Present Marsh Research in Public Workshop Series CWC_PubEdWorkshopIMG_2243a

An old philosophical question asks, “If a tree falls in a forest and no one is around to hear it, does it make a sound?” Similarly, if a scientist makes an important discovery and people do not hear about it, will it matter?  Scientists are conducting research about oil and other impacts on coastal marine Read More
