Meltwater fluxus and the loss of organic matter

Han Dolman

The current extent of ca. 36,000 km2 of glacier ice on Svalbard is decreasing rapidly. This effects meltwater fluxes and the quantity and quality of sediments and organic matter in it. While the organic matter (carbon) content in glacial waters are typically low, this material is known to be ancient in age and highly bioavailable, serving as food source for nearby coastal waters. We plan to follow up and expand upon SEES2015 sampling and analysis by collecting additional samples across a gradient of glacial coverage in Svalbard to determine how glacial retreat will alter dissolved organic matter characteristics.
