Inorganic carbon and total alkalinity at Western Channel Observatory station E1 (2010 - 2014).

Dissolved inorganic carbon and total alkalinity measurements sampled from station E1, part of the Western Channel Observatory, and analysed at Plymouth Marine Laboratory. These measurements, together with temperature, salinity, total phosphate and silicate, are used to calculate additional carbonate system parameters (pH, pCO2, saturation states of calcite and aragonite, HCO3- and CO32-) using the programme CO2sys [Pierrot et al 2006], with dissociation constants from [Mehrbach et al. 1973] refit by [Dickson and Millero 1987] and for KSO4 from [Dickson 1990].
