Exiting the jet

Monday, July 14th, 2008

Sea surface temperature image below has the glider track and the observed current vectors overlaid. RU17 is making the turn towards the eastern side of the cold eddy (difficult to see in this image).


As shown in the time series plot below, current speeds are decreasing as we leave the strong jet to the southwest that has blocked our path forward for a few days now.  Current direction from the most recent surfacing (4 am, not shown here) is even more favorable, continuing to decrease and turn to the west.

We expect this trend to continue over the next day.  Currents should continue turning clockwise, first to the west, then to the northwest, and finally to the north.
