Concentration data used to calculate sodium adsorption ratios for sediments collected from Tilling Farm and Warton sands saltmarshes. Extracts for cation analysis were prepared using methods highlighted in Rowell 1994 and Chirol 2021 (SAR = [Na+] /([Ca2+] + [Mg2+])0.5 with the concentration in mmol-1). Final cation conentrations and dilutions were calculated using sediment mass in 'mass for SAR calc'. Quality control (QC) for ICP analysis are also provided. SAmples were collected from varying depths and in triplicate.
