Read the report.

Approximately 80 percent of oil released in the Gulf of Mexico from the Deepwater Horizon disaster remains, finds a report released yesterday by the University of Georgia and Georgia Sea Grant.

Five scientists from various scientific institutes analyzed data from an Aug. 2 National Incident Command report, which stated that only 25 percent of of the oil from the estimated 4.9 million barrel spill remained in the water.

“One major misconception is that oil that has dissolved into water is gone and, therefore, harmless,” said Charles Hopkinson, director of Georgia Sea Grant and professor of marine sciences at the University of Georgia in a statement. “The oil is still out there, and it will likely take years to completely degrade. We are still far from a complete understanding of what its impacts are.”

This series digs into Mississippi’s systemic issues and sheds light on responses to them in other communities. Beyond just reporting on problems, these stories interrogate their causes and inspect potential solutions.

Mississippi native Donna Ladd and partner Todd Stauffer founded the Jackson Free Press in 2002 in the capital city. The heavily awarded local newspaper did many investigations heralded across the state and nation and served as a paper of record due to its diversity, inclusion, in-depth reporting and deep connection to readers and dedication to narrative change in and about Mississippi. In 2022, the nonprofit Mississippi Free Press, founded by Ladd and JFP Associate Publisher Kimberly Griffin in 2020, purchased the journalism assets and archives of the Jackson Free Press. A Google grant through AAN Publishers enabled Newspack's integration of the JFP archives into the Mississippi Free Press website to become part of a more searchable archive of recent Mississippi history and essential journalism.
