| contents | We present continuous records of 1 cm resolved sulfate concentrations, insoluble particle number and mass concentration, and liquid conductivity using a Continuous Flow Analysis (CFA) system (Bigler et al., 2002; Bigler et al., 2011; Erhardt et al., 2022) from the North Greenland Ice Core Project (NGRIP; 75.10°N, 42.33°W; 2941 m a.s.l.) and estimated volcanic sulfate mass depositions for the time period 79.14 and 80.48 ka BP on the GICC05modelext chronology, transferred to the AICC2012 chronology (Veres et al., 2013; Seierstad et al., 2014) using a common volcanic marker in EPICA Dome C ice core dated 79.51 ka BP. The reconstruction is based on sulfate measurements employing high-resolution continuous flow analysis. Volcanic eruptions are detected when annual sulfate concentrations exceeded the background concentrations + 4 times the median of the absolute deviation. Background concentrations are estimated using a 181-point running median. Volcanic sulfate deposition rates are calculated by subtracting the background concentrations from total sulfate concentrations using thinning corrected estimates of mean ice accumulation rates at the ice-core site. |
