Description

Maps of annual mean aragonite saturation state (Ωarg) for the Greater Caribbean Region between 1988 and 2007 (top figure). In direct consequence to increasing atmospheric CO2 concentration, the surface waters of the region are growing less saturated with respect to the carbonate mineral phases that comprise the shells and skeletons of a large number of marine organisms.

A time-series depicting the monthly regional mean Ωarg-values (bottom figure). Regionally, the waters exhibit maximum values in August and September when, despite higher pCO2,sw-values that tend to drive down Ωarg, the increased SSTs yield elevated carbonate ion concentrations and a reduced carbonate mineral solubility thereby driving up Ωarg.

Final-values are denoted as filled-symbols while preliminary-values are shown as open-symbols. As quality controlled atmospheric CO2 data become available from NOAA GMD, the data are reprocessed and finalized. Note, that prior to December 2003 the model is dependent upon NOAA WOA Climatological Salinity (SSS) and are denoted as triangles. After this date the model applies salinity fields derived from the HYCOM + NOCDA Global 1/12 degree Analysis and is denoted as circles. In instances where gaps exist in the HYCOM-based salinities, climatological salinities are substituted. These include the following months (Dec-2005, May-2005, Mar-2007, Feb-2008, Jan-2009).
