The Imiq Hydroclimate Database houses hydrologic, climatologic, and soils data collected in Alaska and Western Canada from the early 1900s to the present. This database unifies and preserves numerous data collections that have, until now, been stored in field notebooks, on desktop computers, as well as in disparate databases. Synthesizing and analyzing the large-scale hydroclimate characteristics of this important climatic region have been made easier with this searchable database. The data, originally collected in a Microsoft SQL Server 2008 relational database, has been migrated to an open source PostgreSQL and PostGIS environment. The Imiq Data Portal provides public access to portions of the Imiq Hydroclimate Database through a simple web interface with search and visualization options. Data and metadata are easily downloaded in a common file format and have been normalized into common units. The Imiq Data Portal has been designed to meet the needs of land stewards, resource managers, and scientific researchers. The web-services that provide data to the portal may also be accessed directly to obtain information.
