CB-06 buoy near Coos Bay and Cape Arago, OR (43.3°N, 124.5°W)

The CB-06 mooring is located 6 nautical miles offshore of Coos Bay and Cape Arago in the northern California Current Ecosystem along the southern Oregon coast. This region supports diverse and productive benthic and near shore ecosystems as well as economically important groundfish and crab fisheries. The combination of upwelling and high productivity can lead to bottom water hypoxia, which makes this region a unique setting to track the combined impacts of ocean acidification (OA) and hypoxia on the biological system.

CB-06 was established in June 2017 in collaboration with Drs. Hales and Kosro from Oregon State University after being previously deployed at NH-10 off Newport, Oregon during an intercomparison with Oceans Observatory Initiative (OOI) Endurance Array observing assets.  The OA observations at CB-06 are supported by NOAA's Ocean Acidification Program and also leveraged by existing activities supported by the Northwest Association of Networked Ocean Observing Systems (NANOOS).
