A Hard Day’s Night

Aboard the RV Investigator we are approaching the middle stations along our 110°E line and have proceeded from cool, temperate waters to warmer more subtropical waters. Operations are proceeding smoothly – watches swop with 12-hour regularity, equipment gets deployed, samples get taken as per the daily roster and we no longer really know which day of the week it is!

|Even in the dead of night instruments are deployed from RV Investigator. Here an APEX Deep ARGO buoy is being deployed for the Japanese Agency (JAMSTEC) as part of the international collaboration of the IIOE-2. Photo: Karlie McDonald.|

And, yes, it must be near the weekend as the footy tipping competition is in full swing!
