Eleven men perished on a drilling platform sixty miles off the coast of Louisiana early on April 20, 2010, and the federal government’s relationship with offshore oil has never fully recovered. Not only did the Deepwater Horizon rig sink, but it also created a wound in the Gulf floor that bled for 87 days in a row, releasing an estimated 134 million gallons of crude into waters that were home to bottlenose dolphins, shrimp fleets, and Kemp’s ridley sea turtle nesting grounds. That statistic does not age silently.
It’s important to note that NOAA mobilized within three hours of the explosion. For three hours. Before the majority of Americans saw the first news photos, the agency used satellite imagery, ocean current modeling, and real-time trajectory tools to predict where the oil was headed. Leaning over the sides of white ships, scientists on research vessels watched the water turn rust-brown while attempting to measure something that continued to move. The spill response community had never dealt with a scale like this before, and the systems in place were just not designed to handle it.
Over the ensuing years, a reconstruction of how federal science functions in times of crisis emerged rather than a cleanup. For 107 days in a row, NOAA’s oil spill trajectory model, GNOME, produced daily forecasts. ERMA, a web-based mapping system that layered ship locations, weather information, shoreline conditions, and ocean currents into something that people could actually use, became the official common operating picture for all federal, state, and local responders involved. The oiled shoreline, which was eventually measured at more than 1,300 miles, might have been worse without those tools.
Over 20,000 field trips and over 100,000 samples were collected during the ensuing damage assessment, which took place between 2010 and 2015. In order to restore fisheries, wetlands, oyster reefs, and coastal habitat throughout all five Gulf states, a federal court approved a $8.8 billion settlement with BP in 2016. This was the largest natural resource damage settlement in American history. Technically, that money started something that is still ongoing.
Observing the restoration efforts over time gives the impression that the Deepwater Horizon accident served as a kind of unintentional stress test for the entire American environmental response system. Rebuilt nesting grounds are being visited by brown pelicans. Where none previously existed, new oyster reefs are emerging. Significant wetland restoration initiatives have produced quantifiable outcomes along Louisiana’s disappearing coastline. It would be dishonest to overlook these genuine victories.
Deep-sea corals, however, are still clearly declining. Fifteen years after the damage was done to more than 700 square miles of deep-sea habitat, the most severely affected corals have not recovered and continue to exhibit what scientists call deteriorating health. The population of the Kemp’s ridley sea turtle, which was already precarious prior to 2010, continues to face difficulties. There is still pressure on rice’s whales. It’s still unclear what, if anything, will take the place of the BP settlement funding when it expires in 2032.
Reading through NOAA’s account of those fifteen years, the Deepwater Horizon timeline actually demonstrates how catastrophic environmental events compound rather than resolve. American waterways are regularly monitored for new oil releases by the satellite mapping program that was started in near-panic during the spill. Researchers around the world now have more knowledge about how oil impacts marine species across the whole ecological spectrum thanks to the toxicity dataset created by post-spill studies, which became a permanent scientific resource. In other words, infrastructure was created by crisis. Although it’s uncomfortable to feel hopeful about, it’s important to acknowledge.
The more difficult question that looms over all of this is whether or not the federal government has learned enough, and whether or not it will remember what it has learned when the funding expires and the news has long since moved on. Most Gulf communities that witnessed the collapse of their fishing seasons in 2010 have recovered. The story of the ecosystems beneath those same waters is more nuanced; they are still developing, being measured, and awaiting results that science cannot predict on its own.
