Station P (ocean measurement site)

Not to be confused with the former British base on Antarctica called Station P.

Station P, or Station PAPA, is an ocean measurement site used to collect data on the salinity, density, pressure, and other variables found in the ocean. It is located at 50 degrees north latitude, 145 degrees west longitude (water depth, 4220 meters). Since December 19th, 1949, Station PAPA has been used to measure ocean climate, and has one of the oldest records of oceanic time series data.

The site was established by the US Navy in 1943. In 1951, US funding to maintain continual presence ran out and observational responsibility was passed to Canada. The site was staffed continuously until 1981. Starting in 2007, automated observations have been made by the National Oceanic and Atmospheric Administration.
