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 on two cruises from Punta Arenas, Chile. Cruise NBP16-09 will service the OOI Argentine Basin array and cruise NBP16-10 will service the OOI Southern Ocean array. While on board, the team will conduct the following activities: (1) Survey the bathymetry of the site to establish the positions for the four moorings; (2) Deploy the four replacement moorings; (3) Recover the four existing moorings; (4) Recover and deploy gliders in support of horizontal and vertical sampling in and around the array; (5) Carry out shipboard sampling in support of calibration and validation of the deployed sensors on the moorings and gliders.
