Abstract

AKTEMP is a cloud-based database platform for storing and accessing stream and lake temperature monitoring data across Alaska. The website allows users to upload, review, explore, and download data. Data can be uploaded either as a single file or as multiple files, which can be uploaded simultaneously as a single batch. After uploading, an interactive QA/QC tool can be used to review and flag data representing erroneous or abnormal measurements (e.g., out of water). Users can explore available data at all sites statewide or within specific hydrologic basins (i.e. HUC4, 6, or 8) using spatial filters. Additionally, users can download both the raw and daily- aggregated timeseries at one or more sites along with the accompanying station metadata. The project team has developed instructional videos, decision tree flowcharts, and a user guide to aid data providers and public users. The system architecture for AKTEMP was based on the Spatial Hydro-Ecological Decision System (SHEDS) northeast stream temperature database, which was developed by Walker Environmental Research in collaboration with USGS. AKTEMP was released in early 2023 and currently serves freshwater temperature data at nearly 900 sites across Alaska. Use of AKTEMP is free and open and will continue to be supported by staff at UAA's Alaska Center for Conservation Science. We invite the community to take advantage of this database by uploading your own data, and/or exploring data uploaded by others to meet your needs.
