Saildrones completed a number of different missions in the Gulf of Mexico during 2015.
In association with NOAA and the University of Southern Mississippi, we deployed SD 128 on a shelf slope interaction study, to measure, amongst other things, the nitrate flow from the Mississippi delta.
SD128 took 3 days to navigate the rig field through light winds to get to the study area. The slightly southerly track on the outbound route was to take advantage of the loop current.
The vehicle then stayed on station for 115 days, repeating 2 courses that were parallel and perpendicular to the continental shelf.
SD 128 returned to Cocodrie, under its own sail power after sailing 4773 NM in 120 days.
