Gliders under control: we07, we08, we09, we10, we12

Coordination plan: two gliders (we08 and we10) are assigned to the northern
track in a counter-clockwise direction and will seek to remain on
opposite sides of the track. Similarly, gliders we09 and we12 are
assigned to the middle track in a counter-clockwise direction and will
seek to remain on opposite sides of the track. Gliders we07 is assigned
to the southern track in a counter-clockwise direction. In addition, the
two pairs of gliders on the northern and middle tracks will seek to
become synchronized, i.e. for each glider on the northern track there
should be a glider at the same point on the middle track. 

Coordination summary: Since gliders we08 and we12 came under coordinated control
approximately 2300 GMT yesterday, they have been making good headway to
their track assignments. In fact, we12 has reached the middle track and
is rounding the southern, onshore corner. Glider we08 is expected to
reach the onshore edge of the northern track this afternoon. Glider we10
is rounding the offshore corner of the northern track and heading south
in substantially reduced flow conditions relative to yesterday. The flow
on the northern edge of the glider sampling domain is substantially
weaker than was expected. Nonetheless, there is a strong (25+ cm/s)
northern/offshore flow in the southeastern portion of the sampling
domain. Glider we09 was subject to this flow when it reached 50+ cm/s
effective speed while crossing the middle track. Both we09 and we07 are
approaching the offshore edge of their respect boxes. 

Glider OA Flow summary: the strong northern flow along the northern edge
of the sampling domain has subsided a bit but still persists offshore of
the northern edge. Northern flow has strengthened in the south
eastern portion of the sampling domain in excess of 25 cm/s.

Outlook: the 24 hour coordination prediction looks good for the
four gliders on the northern and middle tracks. The southern track has
only one assigned glider in anticipation of an additional glider
deployment from the Santa Cruz vicinity early this week.
