CCE2

California Current Ecosystem Mooring 2 (CCE2) (34.324°N, 120.814°W)

A MAPCO2 system was deployed on a California Current Ecosystem Interdisciplinary Biogeochemical Mooring on January, 2010. This mooring is part of a multi-investigator, multi-disciplinary project with two surface moorings in the California Current (the other is CCE-1) with a sensor suite covering biological, chemical, and physical oceanography as well as meteorology. The objectives are to resolve event-scale ocean phenomena and to understand linkages between changes in the physical-chemical environment and the responses of ocean biota. This project is closely coordinated with other projects off of Southern California such as CalCOFI, LTER, and CORC.

CCE-2 is positioned on the shelf break on the California Coast, where localized upwelling processes are at their maximum. For more information about the buoy and other sensors, please visit UCSD's California Current Ecosystem Data Page.

On March 24, 2012, a surface seawater pH sensor was added to the CCE2 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.
