Datasets of aromatic acids (vanillic and para-hydroxybenzoic acids) over the past 2600 years from Akademii Nauk ice core drilled on the Severnaya Zemlya archipelago in the Eurasian Arctic are included. The ice core was drilled from 1999-2001 (Fritzsche et al., 2002) to a depth of 723.91 m (Fritzsche et al., 2005). The datasets consist of depths, ages, and concentrations of these aromatic acids. The vanillic acid concentrations have an uncertainty of about 7%. The para-hydroxybenzoic acid measurements have an uncertainty of about 15%. The limits of detection of vanillic acid and para-hydroxybenzoic acid are 0.01 ppb and 0.05 ppb (by mass), respectively. The limit of detection is defined as 3x the standard deviation of MilliQ water blanks. The timescale used was developed by comparing high resolution multi-element continuous flow measurements of the Akademii Nauk ice core to other Arctic ice cores (following Sigl et al., 2013).
