Read MoreGlider Ops
IRMINGER: In addition to fixed moorings, the OOI Irminger Sea Array consists of autonomous gliders. Two gliders were deployed to the array for a one year deployment, and one glider deployed last year was recovered. The gliders sit on the back deck prior to deployment so that the glider team on shore can communicate with…
Read MoreProfiler Mooring in the Water
IRMINGER: Another gray day in the Irminger Sea and another OOI mooring in the water. The Profiler Mooring consists of a top sphere at 150 m with upward- and downward looking bioacoustic sonar instruments, and a profiler which crawls up and down through the water column measuring conductivity, temperature & depth, dissolved oxygen, fluorescence and…
Read MoreHybrid Profiler Mooring Recovered
STATION PAPA: The Station Papa moorings are replaced on a yearly schedule. Here the OOI-CGSN team recovers the Hybrid Profiler Mooring. The yellow vehicle seen on the mooring wire is a Wire-Following Profiler (WFP). The vehicle moves up and down the wire sampling the water column for salinity, temperature, pressure, dissolved oxygen, chlorophyll, and current…

Read MoreSurface Mooring Deployed
IRMINGER: The OOI-CGSN team arrived at the OOI Irminger Sea Array ahead of a storm and were able to get the large Surface Mooring deployed. Although conditions were overcast and drizzly, the winds and seas were relatively calm. The wind turbines on the buoy began to spin immediately. The wind turbines and solar panels will…
Read More8 Day Transit Provides Prep Time
IRMINGER: It takes eight days to transit from Woods Hole to the Irminger Sea. During that time, the OOI-CGSN team keeps busy preparing for their deployments. The mooring components are laid out on the back deck and connected together so that the team can run the moorings and make sure the controllers and instruments are…
