April 6, 2011, Dr. Chris Reddy collects an oil sample found on a large piece of debris that washed ashore on the Chandeleur Islands, LA following the spill. The Chandeleur Islands are a chain of barrier islands off the coast of Louisiana in the Gulf of Mexico and are a part of the Breton National Wildlife Refuge. (Photo credit: Catherine Carmichael)

Saving the World with Magic Bacteria

December 10, 2012

The natural microbial community in the water column and on the sea floor of the northern Gulf of Mexico (GOM) surprised the watching world in the aftermath of the Deepwater Horizon Oil Spill (DHOS) by quickly working to help mitigate the effects of the oil.

The injection sled is equipped and ready for deployment from the RV Brooks McCall. The white bumpers provide buoyancy for recovery. The grey horizontal tubes, next to engineer Brian Guest, sample salinity to calibrate the CTD behind them. The tracer reservoirs (center) have batteries that run the injectors. The yellow “hard hats” encase hollow glass spheres, making the sled neutrally buoyant as it streams behind a cable when towed at 1 knot. (Photo credit: Laura Spencer)

GISR at Sea: Tracing the Path of Oil Beneath Gulf Waters

December 7, 2012

Science pioneers are blazing a trail to identify pathways oil and gas use to move from deep to surface waters – an entry point for pollutants to damage shorelines and become airborne.

Figure 1. In this 3-D representation of the chemical analysis of COREXIT 9500, each peak represents one or more chemical structure. The line across the bottom shows retention time, the left axis intensity, and the diagonal axis molecular weight (labeled m/z). The large peak at ~15 minutes is DOSS, or dioctyl sodium sulfosuccinate, the active ingredient in most dispersants.

Deconstructing Dispersants

November 20, 2012

In the aftermath of the Deepwater Horizon oil spill (DHOS), the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling estimates that responders sprayed over 1.8 million gallons of the dispersant Corexit 9500 into the northern Gulf of Mexico (GOM).

GoMRI Research Board Vice-Chair Margaret Leinen Elected as AGU President

November 12, 2012

In early October, the American Geophysical Union (AGU) elected Dr. Margaret Leinen as their next president. She begins a two-year term as president-elect in January 2013, followed by a two-year term as president.

5 Million Data Points and Counting

November 8, 2012

As the Globalstar transmission shut down approaches, ending the GPS data collection phase of CARTHE’s Grand Lagrangian Deployment (GLAD), the team is still collecting data from the largest upper-ocean dispersion experiment of its kind.

Stories from the Field: The Next Best Thing to Being There

November 8, 2012

Students, teachers, and journalists joined scientists on board research expeditions and in labs this summer and shared their experiences online.

Working Smart: Deep-C and NOAA Collaboration Improves Gulf Oil Research

November 8, 2012

“Highly successful” is how Chief Scientist Ian MacDonald described his recent research cruise on the RV Weatherbird II to identify natural oil seeps to use as control sites as part of a larger effort to study the effects of oil and gas in the deep sea environment.
