| Summary: | <p>A high-quality dataset of surface water fugacity
of <span class="inline-formula">CO<sub>2</sub></span> (<span class="inline-formula"><i>f</i>CO<sub>2w</sub></span>)<span class="note-anchor" id="fna_Ch1.Footn1"><a href="#fn_Ch1.Footn1"><sup>1</sup></a></span>, consisting of over a
million observations, and derived products are presented for the northern
Caribbean Sea, covering the time span from 2002 through 2018. Prior to
installation of automated <span class="inline-formula"><i>p</i>CO<sub>2</sub></span> systems on cruise ships of Royal Caribbean International and subsidiaries, very limited surface water carbon
data were available in this region. With this observational program, the
northern Caribbean Sea has now become one of the best-sampled regions for
<span class="inline-formula"><i>p</i>CO<sub>2</sub></span> of the world ocean. The dataset and derived quantities are
binned and averaged on a 1<span class="inline-formula"><sup>∘</sup></span> monthly grid and are available at
<span class="uri">http://accession.nodc.noaa.gov/0207749</span> (last access: 30 June 2020)
(<a href="https://doi.org/10.25921/2swk-9w56">https://doi.org/10.25921/2swk-9w56</a>; Wanninkhof et al., 2019a). The derived
quantities include total alkalinity (TA), acidity (pH), aragonite saturation
state (<span class="inline-formula">Ω<sub>Ar</sub></span>) and air–sea <span class="inline-formula">CO<sub>2</sub></span> flux and cover the region
from 15 to 28<span class="inline-formula"><sup>∘</sup></span> N and 88 to 62<span class="inline-formula"><sup>∘</sup></span> W. The gridded data and products are used for determination of status and
trends of ocean acidification, for quantifying air–sea <span class="inline-formula">CO<sub>2</sub></span> fluxes and
for ground-truthing models. Methodologies to derive the TA, pH and <span class="inline-formula">Ω<sub>Ar</sub></span> and to calculate the fluxes from <span class="inline-formula"><i>f</i>CO<sub>2w</sub></span> temperature and
salinity are described.</p> |
