Please subscribe to the ACO-status mailing list for future ACO operational advisories and alerts.

The BSP2 dislodged from the bottom on 4/11/18, 00:53 UTC, moved to 25-30 mab and is floating with the current. CTD3, BPR pressure and fluorometer data may be affected.

New ACO instruments were installed during the ACO-3 cruise on 2014/11/01. Click here for ACO-3 videos.
