Scientists analyzed radiocarbon isotopes, which identify the source of carbons in compounds such as oil and methane, and applied those “fingerprints” to quantify recovery of deep-seafloor sediment contaminated by Deepwater Horizon.

Scientists can use radium isotopes, which are released from oil in seawater and decay at a specific rate, as geochemical tracers to investigate marine processes involved in oil degradation.

Oil, gases, and bubbles jet out together during a deep-ocean petroleum blowout, and the oil quickly breaks up into different-sized droplets. Predicting the sizes of these droplets is critical to determine how long it will take the oil to reach the ocean’s surface and the resulting oil slick’s size.

Researchers analyzed the combined effects of photooxidation and biodegradation on sand patties associated with the Deepwater Horizon incident. The scientists found that irradiation contributed to increased concentrations of dissolved organic carbon, which leached from sand patties penetrated by seawater.

Louisiana State University scientists quantified Louisiana island erosion pre- and post-Deepwater Horizon to determine the shoreline retreat rate when oiled, the length of time that oiling effects lasted, and whether or not there was recovery.

CARMMHA Provides Update on Research Progress
The blog post details the consortium’s progress in several major research categories including cardiotoxicity, immunotoxicity, and dietary assessments, field sampling projects, and integrative modeling.
RECOVER Tool Tuesday Profile Highlights Radios
Participants aboard the research vessels R/V Walton Smith and Yellowfin University of Miami’s use radios for important communications between consortium researchers and with the captain and crew. Radio communications can help researchers relay important information such as travel plans and fish size.
