Acoustic Tests
Here 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.

Following the loading of the equipment on the RV Sikuliaq, the moorings are assembled and tested during the transit to the Station Papa site.

With beautiful Seward, Alaska as the backdrop, RV Sikuliaq departs for the Station Papa 10 mooring and glider deployment expedition.
Read MoreEssential Equipment
Most people think about the instrumentation and the electronics on the OOI moorings. But the moorings wouldn’t hold position for 12 months through stormy weather without these pieces of equipment! These are the subsurface mooring 6000 lb mace anchors needed to keep everything in place.

And they are back! After 19 days, and successful completion of six mooring deployment/recoveries, the Station Papa 9 team aboard the R/V Sikuliaq arrived in Seattle today. Once through the canal and in port, the team unloaded and began the journey home. Well done, team.

We may be interested in the ocean, but sometimes the ocean is interested in us! The Station Papa 9 cruise had some inquisitive visitors this year including these sperm whales and seals.

NOAA was also onboard the R/V Sikuliaq to turn their surface mooring. OOI is always happy to collaborate with other scientists and institutions! After a year in the water, this mooring was host to some marine life as it was brought on board.
Read MoreComponents are key
The subsurface moorings at Station Papa have various components that are all important for the collection of scientific data. The orange spheres provide buoyancy to keep the mooring vertical and instruments at the desired depth. The controller cage manages the sampling rate and data collection from the oceanographic instruments on the mooring. The profiler…
Read MoreMooring recovery
Recovery of the old moorings is extremely important to the OOI program. Even though OOI telemeters data in near real-time, there can be gaps. When the moorings are recovered, OOI team members also recover all the raw data at its highest resolution. These data are also uploaded to the OOI site and made available to…
Read MoreBefore and After
Station Papa 9 team members spent some time during transit decorating Styrofoam cups, which were later placed in a CTD rosette. The CTD Rosette, depending on the sampling plan, may sample to several hundred or even thousands of meters below the surface. The after picture shows what pressure does to Styrofoam, an example of…
