caption_attribution_description: English: Annual mean sea surface dissolved inorganic carbon (DIC) for the present day (normalised to year 2002) from the Global Ocean Data Analysis Project v2 (GLODAPv2) climatology. Sources are given below. This field was derived from present day measurements of DIC with the signal of anthropogenic DIC removed using a mathematical technique. It is plotted here using a Mollweide projection (using MATLAB v2013a). Note that the GLODAPv2 climatology is missing data in certain oceanic provinces including the Arctic Ocean, the Caribbean Sea and certain inland seas. Lauvset, S. K., Key, R.

context_page_description: The Global Ocean Data Analysis Project is a synthesis project bringing together oceanographic data, featuring two major releases as of 2018. The central goal of GLODAP is to generate a global climatology of the World Ocean's carbon cycle for use in studies of both its natural and anthropogenically-forced states. GLODAP is funded by the National Oceanic and Atmospheric Administration, the U.S. Department of Energy, and the National Science Foundation.
  The first GLODAP release was produced from data collected during the 1990s by research cruises on the World Ocean Circulation Experiment, Joint Global Ocean Flux Study and Ocean-Atmosphere Exchange Study programmes. The second GLODAP release extended the first using data from cruises from 2000–2013. The data are available both as individual "bottle data" from sample sites, and as interpolated fields on a standard longitude, latitude, depth grid.
context_section_description: The following panels show sea surface concentrations of fields prepared by GLODAPv1.1. The "pre-industrial" is the 18th century, while "present-day" is approximately the 1990s.
  The following panels show sea surface concentrations of fields prepared by GLODAPv2. The "pre-industrial" is the 18th century, while "present-day" is normalised to 2002. Note that these properties are shown in mass units (per kilogram of seawater) rather than the volume units (per cubic metre of seawater) used in the GLODAPv1.1 panels.
