The Deepwater Horizon disaster of 2010 was a tragedy in many respects, but in one detail, BP was lucky. At least it could find the oil. As more and more companies venture into the oil- and gas-rich waters north of the Arctic Circle, they are being forced to imagine another oil-spill scenario, one in which the response effort is impeded by storms, fog, high winds and massive drifting ice floes; in which visibility is minimal, where the nearest coast guard station is over 1,000 miles away and where spilled oil accumulates on, in and under the ice. Such considerations have led to the development of new technologies to detect and deal with spilled oil in remote, icy seas. In open water conditions such as those in the Gulf of Mexico during the Deepwater Horizon spill, the primary method for oil-spill detection involves satellite-mounted synthetic-aperture radar (SAR). The most promising detection technology is ground-penetrating radar (GPR), which uses high-frequency radar signals. GPR has been shown to be particularly effective in detecting oil under snow.
