NOAA's West Coast Ocean Acidification Cruise (WCOA2011) collected surface underway measurements of carbon dioxide partial pressure (pCO2) and other variables. The cruise took place from August 12 to 30, 2011, aboard the R/V Wecoma, occupying 95 stations from northern Washington to southern California. This effort was conducted in support of the NOAA Ocean Acidification Program's coastal monitoring and research objectives.
Use Cases
- Analyzing spatial patterns of surface ocean carbon dioxide based on underway pCO2 measurements
- Studying temporal changes in coastal ocean acidification parameters by comparing with 2007 cruise data
- Modeling carbon system dynamics in the California Current System using synoptic physical and biogeochemical data
- Assessing ocean acidification impacts on coastal ecosystems based on key carbon parameters
Strengths
- Data originates from a dedicated, synoptic research cruise designed for ocean acidification monitoring
- Covers 95 stations along thirteen transect lines from northern Washington to southern California
- Includes comparisons with historical data from the 2007 West Coast Carbon cruise and CalCOFI stations
Limitations
