Ocean Station Papa (50.1°N, 144.9°W)
Ocean Station Papa (145°W, 50°N) has one of the longest records of time-series measurements in the ocean. Through support from the US NSF and NOAA and in collaboration with the Canadian DFO Line P Program, a surface mooring was deployed in June 2007 at Ocean Station Papa to monitor ocean-atmosphere interactions, carbon uptake, and ocean acidification. It is an Ocean Climate Station (OCS) mooring that is part of the global network of OceanSITES time series reference sites.
On June 15, 2010, a surface seawater pH sensor was added to the Papa Mooring mooring. By measuring pH in addition to pCO2, we are able to more accurately and precisely study the changes associated with ocean acidification. All seawater pH observations are shown in the second figure below.
