Abstract
The Historical Sea Ice Atlas tool aggregates a wide variety of sea ice observations and measurements, from whaling ship logbooks from 1850 to near real-time passive microwave satellite data in the present, to generate a sea ice time series over 150 years long for the seas surrounding the state of Alaska, USA. This resource can be used to explore the trends in sea ice extent and concentration at multiple scales through time. The geographic extent of the data maintained in the Atlas is 500 km from shore, and the area includes the Bering Sea north of the Aleutian chain, into the Chukchi and Beaufort Seas. It also includes a select number of nearshore bays and inlets that have historical ice records – most notably Norton Sound and Cook Inlet.
