SENTRY
Sentry was equipped with TETHYS, a portable underwater mass spectrometer that can detect tiny quantities of chemicals in seawater. Sentry zigzagged across the area, with TETHYS detecting where chemicals were present and not present. In this way, Sentry and TETHYS revealed the shape and breadth of a plume containing hydrocarbon compounds from Deepwater Horizon. It was more than a mile wide and 600 feet high and flowed for at least 22 miles.
