(Table S4) Total suspended matter concentrations (TSM), particulate organic carbon contents (POC) as well as atomic particulate organic carbon to total particulate nitrogen ratios (POC:PN) of individual Lena Delta surface water samples from 2009 - 2011

1: TSM values for 2009 and 2010 from Winterfeld et al. (2015, companion paper). 2: calculated after subtracting the intercept value at POC = 0 in the POC versus PN plot (Figure S1) for each year from the total particulate nitrogen content, intercept is 0.023 for samples from 2009 and 2010, and 0.028 for 2011 (for more details see Figure S2 and description in text section 4.3.1).
