标题:A 17-year dataset of surface water fugacity of CO2 along with calculated pH, aragonite saturation state and air–sea CO2 fluxes in the northern Caribbean Sea
摘要:A high-quality dataset of surface water fugacityof CO2 (fCO2w)1, consisting of over amillion observations, and derived products are presented for the northernCaribbean Sea, covering the time span from 2002 through 2018. Prior toinstallation of automated pCO2 systems on cruise ships of Royal Caribbean International and subsidiaries, very limited surface water carbondata were available in this region. With this observational program, thenorthern Caribbean Sea has now become one of the best-sampled regions forpCO2 of the world ocean. The dataset and derived quantities arebinned and averaged on a 1∘ monthly grid and are available athttp://accession.nodc.noaa.gov/0207749 (last access: 30 June 2020)(https://doi.org/10.25921/2swk-9w56; Wanninkhof et al., 2019a). The derivedquantities include total alkalinity (TA), acidity (pH), aragonite saturationstate (ΩAr) and air–sea CO2 flux and cover the regionfrom 15 to 28∘N and 88 to 62∘W. The gridded data and products are used for determination of status andtrends of ocean acidification, for quantifying air–sea CO2 fluxes andfor ground-truthing models. Methodologies to derive the TA, pH and ΩAr and to calculate the fluxes from fCO2w temperature andsalinity are described.
