Dissolved inorganic carbon (DIC), total alkalinity, (TA), pH on total scale, water temperature, salinity and other variables collected from discrete sample and profile observations collected during the R/V Akademik Ioffe along Repeat Hydrographic Section 59.5N cruise AI41 (EXPOCODE 90KD20130626) in the North Atlantic Ocean from 2013-06-26 to 2013-07-23 (NCEI Accession 0314089)

This dataset consists of dissolved inorganic carbon (DIC), total alkalinity, (TA), pH on total scale, water temperature, salinity and other variables collected from discrete sample and profile observations collected during the R/V Akademik Ioffe along Repeat Hydrographic Section 59.5N cruise AI41 (EXPOCODE 90KD20130626) in the North Atlantic Ocean from 2013-06-26 to 2013-07-23. The dataset comprises physical and carbonate system data collected during eight summer cruises (2009-2019) along the meridional hydrographic CLIVAR 59.5N section. This repeated section covered the longitudinal span of the subpolar North Atlantic at 59.5ºN between Scotland and Greenland (4.5-43.0ºW), encompassing the Irminger and Iceland basins, and the Rockall Trough. Sampling stations were equidistantly spaced every 20 n.m. apart (~1/3º longitude) in most cruises, with exceptions in 2016 where station spacing was decreased to 10 n.m. over Reykjanes Ridge slopes. Notably, the distance between stations over the east Greenland slope and shelf decreased from 10 n.m. to about 2 n.m.
