| Summary: | The Historical Sea Ice Time Series from the Atlantic Arctic data collection is a compilation of existing century-scale time series derived from historical observations and sea ice charts from a range of sources. The purpose of the dataset is to provide a convenient compilation and consistent description of these data that are published, though scattered. Provided here are various indices of sea-ice conditions, ranging from estimated sea-ice extent, sea-ice edge, sea-ice export and sea-ice incidence (duration). The original time series were constructed by individual researchers using various sources ranging from historical ice charts to annals and other descriptive information. Spatially, the data span the Atlantic Arctic from Newfoundland to the Barents and Baltic Seas. Temporally, the time series range from approximately one to three centuries.
