Updates
Pitching In
May 24, 2023Everyone pitches in where they’re needed most…Kris Newhall is the Chief Scientist on Papa 10, supports deck operations, and here acts as a mobile desk for James Kuo as he completes final comms checks on a flanking mooring. (Kris is holding laptop).
Check, Double Check
May 24, 2023Mooring and instrument systems are checked multiple times prior to deployment. Here Dan Bogorff and James Kuo perform one last communications check on the hybrid profiler mooring sphere and controller cage prior to overboarding.
Pit Crew
May 24, 2023The OOI version of a pit crew. As the Papa Team brings the hybrid profiler mooring onboard, the profiling vehicle is removed before continuing with the recovery.
CTD Deployment
May 24, 2023Here Carmen Greto, an RV Sikuliaq technician, monitors the deployment of a conductivity, temperature, and depth (CTD) rosette. The CTD measures salinity, temperature, and pressure at multiple depths along with taking water samples. These measurements provide a baseline comparison for the newly deployed Papa instruments.
Alaskan Visitor
May 24, 2023An Alaskan local stops by for a visit…a seal dropped by the RV Sikuliaq to give the Papa team some advice on buoy recoveries.
A Year at Sea
May 24, 2023What one year in the ocean looks like…. A flanking mooring 64” sphere before (nice and shiny), and after (with 12 months of marine growth). Marine growth can inhibit the operation of the mooring and instruments and is one of the reasons we need to recover and refurbish the OOI infrastructure on a regular basis.
Deployment Ready
May 19, 2023The RV Sikuliaq is on site at the Papa array. Surrounded by the deck and instrument teams, and vessel crew, Jim Dunn gives a briefing on the deployment of the hybrid profiler mooring. It is always important to make sure everyone understands the operation and their roles, to ensure a successful and safe deployment.
Safety First
May 19, 2023Shipboard safety is always a priority. Early in the cruise all Papa personnel must go through the safety briefing and drills, including how to put on the immersion suit. Here Dan Bogorff and the team try on their suits and discuss emergency scenarios with Capt. Diego and other members of RV Sikuliaq crew.
Acoustic Tests
May 16, 2023Here Jim Dunn of WHOI prepares acoustic releases for a test deployment. They will be lowered into the water and test actuated using an acoustic signal. The acoustic releases are integral to the Papa mooring deployments and Jim will make sure they are all functional before mooring operations begin.
Moorings Tested and Assembled
May 16, 2023Following the loading of the equipment on the RV Sikuliaq, the moorings are assembled and tested during the transit to the Station Papa site.
