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

The CTD3 installed on BSP2 was shutdown on 2016/09/24 at 00:30UTC until further notice to prevent interference with the DQ pressure sensor.

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