Abstract

This paper presents new estimates of solute fluxes from 5 high Arctic glacier basins in Svalbard. These estimates are combined with data from 2 other glacier basins to assess the effectiveness of chemical denudation on Svalbard and to estimate rates of temporary (or transient) CO2 drawdown. They use a solute provenance model to partition solutes into marine, aerosol, atmospheric and crustal components and to estimate their annual fluxes. The analysis shows that a large area of uncertainty in the transient CO2 drawdown estimates exists due to the non-stoichiometric release of solute during silicate hydrolysis
