Measurements of total alkalinity and inorganic dissolved carbon in the Atlantic Ocean and adjacent Southern Ocean between 2008 and 2010
Water column dissolved inorganic carbon and total alkalinity were measured during five hydrographic sections in the Atlantic Ocean and Drake Passage. The work was funded through the Strategic Funding Initiative of the UK's Oceans2025 programme, which ran from 2007 to 2012. The aims of this prog...

| Summary: | Water column dissolved inorganic carbon and total alkalinity were measured
during five hydrographic sections in the Atlantic Ocean and Drake Passage.
The work was funded through the Strategic Funding Initiative of the UK's
Oceans2025 programme, which ran from 2007 to 2012. The aims of this programme
were to establish the regional budgets of natural and anthropogenic carbon in
the North Atlantic, the South Atlantic, and the Atlantic sector of the
Southern Ocean, as well as the rates of change of these budgets. This paper
describes in detail the dissolved inorganic carbon and total alkalinity data
collected along east–west sections at 47° N to 60° N,
24.5° N, and 24° S in the Atlantic and across two Drake
Passage sections. Other hydrographic and biogeochemical parameters were
measured during these sections, and relevant standard operating procedures
are mentioned here.

Over 95% of dissolved inorganic carbon and total alkalinity samples
taken during the 24.5° N, 24° S, and the Drake Passage
sections were analysed onboard and subjected to a first-level quality control
addressing technical and analytical issues. Samples taken along
47° N to 60° N were analysed and subjected to quality
control back in the laboratory. Complete post-cruise second-level quality
control was performed using cross-over analysis with historical data in the
vicinity of measurements, and data were submitted to the CLIVAR and Carbon
Hydrographic Data Office (CCHDO), the Carbon Dioxide Information Analysis
Center (CDIAC) and and will be included in the Global Ocean Data Analyses
Project, version 2 (GLODAP 2), the upcoming update of Key et al. (2004). |
