Station Summary

The global component of the OOI design includes a network of moorings at critical, yet under-sampled, high-latitude locations such as Station Papa in the North Pacific. The array at Station Papa will be occupied in coordination with the National Oceanic and Atmospheric Administration (NOAA), which maintains a surface mooring there. As one of the oldest oceanic time series sites, with surveying conducted in the area since 1949, Station Papa has been an important location in the global network of OceanSITES. OOI is designed to add to the existing infrastructure at Station Papa by adding three additional moorings to the area as well as mobile platforms (gliders) to sample in the space between the moorings.

In July 2013, the first of the OOI infrastructure was deployed at Station Papa, including – one Global Hybrid Profiler Mooring, two Mesoscale Flanking Moorings and three Global Gliders, totaling 57 instruments. The Global Hybrid Profiler Mooring is composed of two types of profilers: a surface piercing profiler operating from ~140 m to the surface, allowing satellite data telemetry, and two wire following profilers, one operating from 307 m to 2,174 m and the other 2,195 m to 4,061 m. The two subsurface Mesoscale Flanking Moorings were deployed to form a triangular array ~40 km on a side. These flanking moorings have their uppermost flotation and sensors at 20 m depth and instruments at discrete depths along the mooring line. Gliders equipped with acoustic modems to relay data to shore via satellite telemetry were deployed to sample within and around this triangular array. These gliders carry sensor suites (see below) with the capability to alter sampling rates during a mission.
