In April 2010, the offshore oil drilling rig Deepwater Horizon, operated by BP P.L.C., exploded in the Gulf of Mexico and triggered the largest accidental oil spill in history. In cooperation with Florida State University, SkyTruth estimated the amount of oil flow from the damaged well using satellite imagery and determined, based on conservative estimates using the visible surface slick, that the flow of oil was between 5 and 25 times greater than BP reported.[6] SkyTruth was the first organization to challenge BP's claims, and continued to monitor and document flow from the well until it was successfully sealed.[7]

SkyTruth's FrackFinder project utilizes public crowd sourcing to map fracking operations on the Marcellus and Utica Shale formations.[8] SkyTruth has mapped out fracking well pads and retainment ponds in Pennsylvania, Ohio, and West Virginia, with further plans to quantify the total impact halos of fracking operations underway. FrackFinder data is publicly available through GitHub. Researchers at Johns Hopkins University used SkyTruth's FrackFinder data to link hydraulic fracturing activity to premature birth, high risk pregnancies,[9] migraines, fatigue, and chronic nasal and sinus symptoms.[10]

On September 16, 2015, SkyTruth in partnership with Google and marine conservation organization, Oceana, launched Global Fishing Watch at the Our Ocean Conference hosted by then-US Secretary of State John Kerry in Washington, DC.[11] Global Fishing Watch continuously publicizes the locations of hundreds of thousands of vessels via their onboard Automatic Identification Systems so that users can individually track vessels through exclusive economic zones, marine protected areas, and other features. SkyTruth and it partners launched Global Fishing Watch as an independent nonprofit in 2017. It has been used by governments, such as that of Kiribati in 2016, to crack down on illegal fishing and fishing in protected waters.[12]

SkyTruth collected data for their initial mountain top removal survey in a partnership with Appalachian Voices, to map the location and growth of mountain top removal (MTR) mines over a 30-year period.[13] It updates data on the extent of mountaintop mining in Central Appalachia annually, and is now monitoring reclamation and revegetation of mined sites as well as coordinating with partners to document the environmental and public health impacts of mountaintop mining][14]].

SkyTruth continuously monitors oil spill activity, investigating United States Coast Guard National Response Center reports and calculating estimates of spill volume from confirmed surface slicks. SkyTruth monitors the chronic leak from Taylor Energy site 23501.[15]

SkyTruth has developed a machine learning model that scans thousands of satellite images a day to identify oil slicks at sea and link slicks with vessel traffic to identify likely polluters. These slicks typically result from illegal bilge dumping, in which vessels release oily bilge water into marine waters offshore. Called Cerulean, this model will soon allow law enforcement, local communities, and others to hold polluters accountable for this routine, but illegal activity.

More broadly, SkyTruth is working to apply machine learning and cloud compute technology to a range of environmental challenges, taking advantage of the exponential growth in satellite data now available and new technologies allow rapid analysis of large datasets. They call this initiative Conservation Vision.
