GoMRI ScientistsVideo and Podcasts C-IMAGE Releases Aerial Video of OneGulf Expedition 3771

Researchers from the Center for Integrated Modeling and Analysis of Gulf Ecosystems (C-IMAGE, a GoMRI funded center) studied fish and seafloor sediments across the southern, western and northern Gulf of Mexico. Their goals were to understand the lasting impacts of oil spills and to develop baseline levels in Gulf waters. This aerial footage shows a Read More

Fact SheetsOutreach ACER Blog Explains Mass Spectrometry 3765

The entry explains that a mass spectrometer, or mass spec for short, has become an important tool in many aspects of science including genetics, biochemistry, pharmaceuticals, environmental science, geology and ecology. The mass spec is an instrument that tells us the masses of specific chemical elements in a sample. Briefly, a mass spec works by Read More

GoMRI ScientistsResearch StoriesVideo and Podcasts GoMRI RFP-V: Impact of Deepwater Horizon oil spill on behaviors of fishers in Gulf of Mexico (Saul) 3761

The Avoiding Surprises: understanding the impact of the Deepwater Horizon oil spill on the decision making behaviors of fishers and how this affects the assessment and management of commercially important fish species in the Gulf of Mexico using an agent-base project is lead by Steven Saul, Arizona State University. The Deepwater Horizon oil spill disrupted Read More

Publication Highlights Study Provides 1st Large-Scale Blue Crab Transcriptome Resource for Insights into Oil Exposure 3849a

Louisiana scientists conducted genetic sequencing on oil-exposed blue crabs to identify genes involved in the blue crabs’ short-term responses to oil. They found approximately 200 genes were significantly up- or down-regulated in gill and hepatopancreatic tissues and about 4,000 genes differed in how their transcripts were spliced together after oil-exposure. The gene expression changes suggest Read More

Research Stories Investigating Louisiana Dolphins’ Reproductive Health After Deepwater Horizon 3838a

Concern about how the Deepwater Horizon oil spill may continue to negatively affect wild bottlenose dolphins living in the spill’s footprint remains high. Researchers supporting the Natural Resource Damage Assessment (NRDA) studied live and stranded dolphins in the heavily affected area of Louisiana’s Barataria Bay and reported that exposed dolphins exhibited increased lung disease, adrenal Read More

GoMRI Students How Grad Student Cui Uses River Diversion Models to Inform Oil Spill Remediation 3831a

When oil from the Deepwater Horizon spill began approaching land, one proposed response was to divert Mississippi River water and sediment into the marshes to try and push surface oil more towards the Louisiana-Texas shelf. Linlin Cui is investigating the impacts of Mississippi River diversions on Barataria Bay hydrodynamics to help inform how future oil Read More

Fact SheetsMaterialsOutreachTeachers and Students ACER Launches Fact Sheets Series 3801

The ACER fact sheet series focuses on the goals and emerging research of the consortium and will consist of 15 total fact sheets, with two fact sheets per each of the seven ACER research groups discussing their research and publications. The first sheet, Introducing ACER, shares the importance of diversity and resilience to the consortium’s research. Read More

GoMRI ScientistsResearch StoriesVideo and Podcasts GoMRI RFP-V: Unraveling the Biotic and Abiotic Chemical Evolution of Macondo Oil (Rodgers) 3797

The The State-of-the-Art Unraveling of the Biotic and Abiotic Chemical Evolution of Macondo Oil: 2010-2018 project is lead by Ryan P. Rodgers, Florida State University. Once released into the environment, petroleum undergoes physical processes that modify its native composition (water washing and evaporative losses) and chemical processes (largely oxidative, i.e. photo-oxidation and biodegradation) that we Read More

Publication Highlights Study Describes Oil Slick Differences in Natural Seeps and Deepwater Horizon 3827

Scientists analyzed synthetic aperture radar satellite (SAR) imagery to compare the magnitude and distribution of floating oil from natural seeps in the Gulf of Mexico and the Deepwater Horizon spill. They found fundamental differences in the surface footprints of chronic background sources (seeps) and large transient anthropogenic discharges (Deepwater Horizon). They published their findings in Read More

GoMRI Students How Grad Student Seubert Interprets Gulf of Mexico Resiliency Using Predator Diet 3820a

Major environmental disturbances such as oil spills can alter a marine ecosystem’s structure and even cause species losses or additions in impacted areas – changes which may have long-term consequences for an ecosystem’s functions. Emily Seubert investigates the diets of marine predators in the northern Gulf of Mexico food web to better understand how the Read More

GoMRI Science Smithsonian Features Luminous Critters Living in the Deep, Dark Gulf 3816

Scientists are finding fascinating discoveries in the largely unknown deep waters of the Gulf of Mexico. Some fishes, invertebrates, and bacteria have evolved a special adaptation to living in dark conditions using bioluminescence. What’s new is the discovery of specific bacteria species that live symbiotically on anglerfish and emit light. The Smithsonian recently published an Read More
