Science Objectives

1) To deploy for at sea testing three prototype moorings of the type to be used in the Coastal and Global Scale Nodes (CGSN) of the NSF Ocean Observatories Initiative (OOI).
2)  To test and characterize the performance of the hardware of these moorings and of the instrumentation and associated electronics.
3) To test power generation systems on the surface buoy and measure power consumption.
4) To test data telemetry and the flow of data from the instruments to the shore.
5) To assess the impacts of bioufouling.
6) To validate mooring deployment and recovery procedures.
7) To test software on the deployed platforms and at the shore facilities.
8) To validate mooring designs.

Science Activities

1) Deploy Coastal Surface Mooring close to 39 deg 55.0 minutes N, 70 degrees, 47.5 minutes W in approximately 520 m of water.
2) Deploy Coastal Profiler Mooring close to 39 deg 55.0 minutes N, 70 degrees, 47.5 minutes W in approximately 520 m of water.
3) Deploy Global Mooring close to 39 deg 30.0 minutes N, 70 degrees, 47.5 minutes W in approximately 2,480 m of water.
