Here’s a great example of why radar is the go-to tool for mapping and monitoring oil pollution (and why I think the US needs to launch a civilian radar imaging satellite). The MODIS/Aqua satellite image taken early yesterday afternoon is mostly obscured by heavy clouds over the area of the ongoing BP spill. But an […]
This Envisat ASAR radar satellite image taken on May 18 shows oil slick entrained in the Loop Current and spreading out to the southeast. Slick and sheen covers 15,976 square miles (41,377 km2), about 50% larger than seen in yesterday’s MODIS image and about twice the size of New Jersey: Some of that apparent rapid […]
NASA/MODIS images have been too cloudy to be much use for May 12 and 13 (see the most recent image we processed, for May 11). But a radar image taken by the Italian COSMO-SkyMed system clearly shows most of the slick in stark detail: The slick covers 4,922 square miles (12,748 km2) on the radar […]
Our friends at CSTARS just posted this stunning image. Taken by the Canadian-operated radar satellite, RADARSAT-2, it clearly shows oil slicks and sheen spread across a wide area (about 5,025 square miles, or 13,000 km2) in the Gulf of Mexico early this morning (May 8): We’ve added some analysis to help you armchair interpreters. Oil […]
We have continued to expand our mining program area to better understand the complex legacy coal plays in Appalachia, and are setting up for a year of even more robust analysis to come. As long as mining mars the rivers and forests of Appalachia, we will continue to monitor it and work to create data that allows communities, regulators, and researchers to hold mine operators accountable for their recovery obligations.
