Gliders under control: we05, we07, we08, we09, we10, we12

Coordination plan: there are two gliders assigned to travel clockwise around the middle and southern track and seek to stay on opposite sides of the track: we07 and we09 are assigned to the middle track; and we05 and we08 are assigned to the southern track. In addition, the two pairs of gliders assigned to these tracks will seek to become synchronized: i.e. for each glider on the middle track there should be a glider at the same point on the southern track. Gliders we10 (counter-clockwise) and we12 (clockwise) are assigned to the northern track.

Coordination summary: Gliders we10 and we12 are situated close to one
another at the northern inshore corner of the northern track and will soon separate as we10 reverses course. Gliders we07 and we09 have very good separation on the middle track. Glider we08 has reached the northern inshore corner of the southern track and will, along with we05, seek to become coordinated with the gliders on the middle track.

Glider OA Flow summary: The strong northern flow has weaked substantially on the offshore edge of the sampling domain. The inshore edge has weak circulating flow.

Outlook: as soon as the separation between we10 and we12 is satisfactory, we10 will reverse course again and resume coordination with we12. In addition, conditions permitting, a new plan will be created to synchronize all three pairs of gliders.
