The Ocean Observatories Initiative (OOI) has constructed a networked infrastructure of sensor systems to measure physical, chemical, geological, and biological variables in the ocean and on the seafloor. This season, the OOI team will only service the Coastal & Global Scale Node (CGSN) at global site 55° S, 90° W (Southern Ocean) from the RVIB Nathaniel B. Palmer (NBP). On this cruise, the team will recover and redeploy the array, which consists of several moorings. The platforms carry multidisciplinary instrumentation and provide the capability for real-time communication of data and control of sampling. The surface mooring captures the surface forcing and upper-ocean variability. The profiling mooring measures the entire water column. Additionally, three sub-surface moorings will obtain vertical profiles and sample the mesoscale variability at the site.
Field Season Overview
Participants will sail on the RVIB Nathaniel B. Palmer from Punta Arenas, Chile, on cruise NBP17-09. They will replace the Global Surface Mooring and the Global Hybrid profiling mooring with two wire-following profilers, and two subsurface Mesoscale Flanking Moorings.
