| Objectives | The objective of the cruise was to service the Eastern Boundary mooring array of the RAPIDMOC project. Six moorings were recovered during PO343 and 13 deployed. Parafil failures on EB1 and EB2 (5000m long moorings located near 24 N, 24 W) during deployment necessitated immediate recovery. This led to an emergency cruise PO345 to recover EB2 and to redeploy EB1 and EB2. PO343 was also notable for the first deployment of seven mini-moorings consisting of a
single microcat between 500m and 50m depth. | ||||||||||||||||||||||||||||||||||||
