Ocean currents can pose significant challenges to safe oil and gas operations in the Gulf of Mexico (GoM). One primary objective of this research program was to better understand the physical mechanisms that cause periods of elevated current velocities. Specifically, the passage of Tropical Revolving Stroms (TRS) over areas of relatively higher sea surface temperature (e.g., loop current (LC) or associated eddy (LCE) may cause elevated currents in the boundary layers of the water column. Two in situ current measurement programs will focus on near bottom and near surface boundary layers and compare them to expert 3-D numerical models. The second primary objective of this program was to develop a technique to survey surface currents in real-time over a large horizontal range of at least 300km per day
