Fact Sheets Sea Grant Releases Boater’s Guide on Handling Oil and Fuel Spills Brochure for boater

The Gulf of Mexico Research Initiative (GoMRI) is pleased to announce a new Sea Grant informational brochure just in time for the summer boating season. The one-page guide gives boaters information on how to prepare for, respond to, and report an accidental oil or fuel spill on their vessels. A Boater’s Guide to Handling Oil and Read More

GoMRI ScienceResearch Stories LADC-GEMM Blog Post Introduces “Will” the Seaglider 4506

“Will” is an underwater autonomous vehicle that will survey and collect acoustic Gulf of Mexico data for approximately eight weeks. Every four hours, the glider surfaces, relays information back to a base station at Oregon State University, and descends again to collect more information. Will is surveying and collecting acoustic data in the Gulf until Read More

GoMRI ScienceResearch StoriesVideo and Podcasts Video Highlights CARTHE Collaboration to Monitor Taylor Oil Leak 4502

The expedition to the Taylor Oil leak site took place in April 2017 and involved joint field operations between CARTHE researchers and organizations including Water Mapping LLC, NOAA, NASA, the Norwegian Meteorological Institute (MET), and MDA Corporation (Canada) to sample the Taylor Energy spill site in the northern Gulf of Mexico. The purpose of this Read More

Video and Podcasts CWC Video Offers R/V Pelican Tour 4498

The clip invites those that were unable to attend the recent Meet the Fleet event to tour the research vessel alongside Board of Regents members and learn about the research that scientists conduct during cruises. Watch the tour!

Scientists analyzed the carbon composition in Seaside Sparrow tissues to learn if oil from the 2010 spill was incorporated into the terrestrial food web. The researchers found reduced radiocarbon and stable carbon concentration levels in the feathers of birds captured at oiled sites compared with birds from non-oiled sites, which is consistent with a fossil Read More

Environmental stressors can cause changes in the abundance and location of certain marine mammal species, which can affect future populations. Researchers can track marine mammals using the number of vocalizations or clicks picked up by acoustic monitoring systems, which can provide insights into their recovery from environmental stressors and, more broadly, deep-water ecosystem health. Sakib Read More

GoMRI Students Grad Student Morales-McDevitt Explores How Nutrients Influence Marine Snow Formation Maya presents her preliminary findings at the 2016 Gulf of Mexico Oil Spill and Ecosystem Science Conference. (Provided by Maya Morales-McDevitt)

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 Read More

GoMRI ScienceResearch Stories ECOGIG Scientists Embark on “Jewels of the Gulf” Research Cruise 4493

The 12-day expedition will assess the effects of oil, methane, and chemical dispersants on deep-sea corals. Remotely operated vehicles at over 1000 meters depth will capture hundreds of high-resolution still images of corals that the researchers have been monitoring since 2010. The team will analyze the images and compare them to those from previous expeditions Read More

LinksMaterials CRGC Releases Database of Oil Spill Claim Sources 4448/4489

Since the 2010 Deepwater Horizon (DWH) oil spill, there has been extensive data collection across the Gulf of Mexico region to better understand the economic impacts of the disaster, particularly on the fishing, seafood, and tourism industries in Gulf Coastal communities that were affected by the spill. There has also been a need to locate Read More

GoMRI StudentsPeople Meet C-IMAGE Student of the Month Melissa Rohal 4479

Melissa Rohal is on a mission to stick up for the little guys. They’re not as attractive as dolphins or sea turtles, but benthic macrofauna are all the rage in the deep ocean. Small animals like worms, copepods and nematodes fill a key role in the food web and act as indicator species of the Read More

GoMRI ScienceResearch Stories CARTHE and NASA Team Up for Radar Validation 4474

The NASA Jet Propulsion Laboratory (JPL) DopplerScat radar is able to measure both ocean currents and wind, which influence the transport of materials in the ocean. JPL members joined CARTHE’s recent SPLASH experiment to validate the radar and expressed a desire to coordinate data exchange with CARTHE in the future. Find out more about this Read More

Scientists analyzed sediment cores from two sites near the Macondo wellhead to characterize possible spill impacts on benthic foraminifera (single celled organisms with a hard shell). The team found elevated Polycyclic Aromatic Hydrocarbon (PAH) concentrations and a significant decrease in density and species diversity for foraminifera. The first signs of benthic recovery took about 1 Read More
