GoMRI SciencePublication Highlights Five-Year Study Finds Deepwater Horizon Negatively Affected Periwinkle Snails 4072a

Scientists conducted a meta-analysis on marsh periwinkle snails using data spanning five years to investigate how the oil spill affected them over time. The researchers found that snails from heavily-oiled sites exhibited decreased density and shell length. There were greater relative proportions of small adults and fewer large adults in heavily-oiled sites compared to reference Read More

Fact SheetsMaterials Sea Grant Releases Brochure on Oil FAQs 4080

The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce a new Sea Grant informational brochure that explores basic aspects of oil as a natural resource and oil spills.  The Sea Grant Oil Spill Outreach Team synthesizes peer-reviewed science for a broad range of general audiences, particularly those who live and work across the Gulf Read More

GoMRI ScienceOutreach DROPPS Hosts and Participates in Community Response Meeting 4126

The quarterly South Texas Coastal Zone Area Committee Meeting is an opportunity for response community members to discuss recent activities and update area contingency plans. DROPPS’ Zhanfei Liu presented on petroleum hydrocarbon analysis and Sarah Cosgrove and Lalitha Asirvadam volunteered to participate in future workgroups, hoping to continue bridging the gap between science and response.

GoMRI ScienceResearch Stories CWC Researchers Use GoPros to Monitor Land Loss 4122

A recent blog post describes how consortium scientists Giovanna McClenachan and R. Eugene Turner used GoPro® cameras to photograph a study site at two-hour intervals during four- to six-week periods between August 2014 and September 2015. Read about their findings here and check out the resulting time-lapse video!

GoMRI StudentsPeople Grad Student Diamante Investigates How PAHs Affect Fish Development 4084a

Polycyclic aromatic hydrocarbons (PAHs) can disrupt important signaling pathways that transcribe genes during fish’s early embryonic development, which could cause malformations. Graciel Diamante is conducting laboratory experiments with fish embryos to understand how weathered PAHs affect fish development. She is also finding that her work demonstrates the importance of perseverance, giving back, and collaborating within Read More

GoMRI SciencePublication Highlights Study Demonstrates Sinking Marine Particles Help Remove PAHs from Water Column 4092a

Researchers measured polycyclic aromatic hydrocarbon (PAH) concentrations in water collected near the Deepwater Horizon site to understand how sinking particles, such as marine snow, influence the residence time of PAHs in the upper ocean.  They observed that dissolved PAH concentrations had decreased by over 1,000 times compared with concentrations reported during and immediately after the Read More

GoMRI ScienceGoMRI ScientistsResearch Stories Building a Rapid Response System for Predicting Water Column Processes and Oil Fate 4101a

As the Deepwater Horizon oil spill unfolded, there were concerns that the Loop Current might transport oil out of the Gulf to the Florida Keys and up the eastern seaboard. This possibility highlighted the need for quick predictions of oceanic flows and subsurface hydrocarbon distribution during and after a spill. Because physical and biochemical processes Read More

Nova Southeastern University researcher Alexander Soloviev and his team generated a short clip in infrared imagery demonstrating how crude and weathered oil slicks respond to dispersant application. Read the CARTHE post here! Watch the video here!

GoMRI SciencePublication Highlights Study Suggests Brittle Stars Limited Deepwater Horizon Impacts on Deep Sea Corals 4106a

Pennsylvania State University scientists analyzed images of impacted and non-impacted deep sea corals to characterize their symbiotic relationship with brittle stars and determine if brittle stars influenced coral recovery from the Deepwater Horizon spill. The researchers observed that corals associated with brittle stars were healthier than corals that were not. Corals with brittle stars settled Read More

GoMRI SciencePublication Highlights Study Develops Predictive Model for Oil-Particle Aggregate Formation 4111a

Scientists developed a new model to predict how much oil from a spill might bind to sediments or organic matter in the water column. The model, A-DROP, introduces a formula that accounts for oil stabilization by particles, particle hydrophobicity, and oil-particle size ratio. The model advances our understanding about the natural removal of oil and Read More

GoMRI ScienceGoMRI ScientistsResearch Stories Building a Benthic Genome Database for Improved Oil Spill Monitoring 4116a

Meiofauna are invertebrate organisms that live in seafloor sediments. These marine creatures perform ecosystem functions such as trophic transfer, biogeochemical cycles, pollution removal, and sediment transport stability. Sensitive to environmental events such as oil spills, meiofauna are valuable bioindicators of impacts from contamination. However, their small size and our limited knowledge about these organisms’ community Read More
