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

Coordination plan: (unchanged) there are two gliders assigned to travel counter-clockwise around the northern and middle tracks which will seek to stay on opposite sides of the track: we07 and we09 are assigned to the middle track; and we10 and we12 are assigned to the northern 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 northern track. Glider we05 is assigned to travel counter-clockwise around the southern track.

Coordination summary: there is good synchronization between glider pairs we09/we10 and we07/we12. Strong poleward flow has displaced gliders we09 and we10 several kilometers north of their assigned tracks. Separation between gliders assigned to the nothern and middle tracks is poor.

Glider OA Flow summary: The size of the strong poleward flow patch is shrinking and is now centered in the northern track leaving moderate poleward and onshore flow in the remainded of the sampling domain.
