Fig. 3: Source contribution of n-alkanoic acids and n-alkanes to the NYA 17–154 OC pool.
From: Greening of Svalbard in the twentieth century driven by sea ice loss and glaciers retreat
The figure shows the relative influence of five distinct end members for n–alkanoic acids and n–alkanes in the Kongsfjorden: marine sediments42,43, soil42,43, coal42,43, ice-rafted detritus (IRD)42, and sediments affected by proglacial river discharge (Bayelva sediment)43. Carbon Preference Index (CPI) and Average Chain Length (ACL) of a n–alkanoic acids and b n–alkanes for the different end members are compared with NYA 17–154 sediment core. Symbols and bars display mean, and s.d. of NYA 17–154 results and each source is derived from literature data.
