Summary

This data set includes 15-minute interval data on stream temperature from low-order streams and main-stem rivers in the Noatak and Kobuk River valleys in Northwestern Alaska, collected during the summer months. The water temperatures were determined using a HOBO Water Temp Pro v2 (Onset Computer Corporation, Bourne, MA, USA)with ±0.2 °C accuracy. Sensors were place in several locations within each stream as well as in the main river below the tributary junction in order to assess stream thermal state.

Purpose

These data were collected from streams in catchments that cross a gradient of ground temperatures, ice content, and vegetation in order to assess spatial and temporal variability in stream temperatures to understand fish habitat. This data is part of the Hydro-Ecology of Arctic Thaw (HEAT) project, which is linking the impacts of warming in the Arctic-Boreal transition zone of Alaska to changes in stream hydrology, biogeochemistry, ecosystems, and fish.
