Carbon Isotope Concentrations in Stream Food Webs of the Arctic Network National Parks, Alaska, 2014-2016

September 18, 2019

This dataset includes information on the carbon samples that were collected from organic and mineral soils, streams, algae, invertebrates, and fish in the Arctic Network Parks.

Carbon cycling in the Arctic is likely influenced by permafrost, which impacts hydrology and the movement of solutes including carbon between soils and stream ecosystems. These samples were collected in order to understand the sources and age of carbon in the food web, as well as to understand carbon cycling within the food web.
