In 1879 the Jeannette set off from San Francisco on an expedition to the North Pole. They got as far as Wrangel Island (71.5N) before being caught in the sea-ice and then drifted with the pack for nearly two years before the ship was crushed and sank. The crew made detailed meteorological records through the entire period, making Jeannette the first ice station.
The logbooks of the voyage survived, and are being transcribed by the oldWeather project (oldweather.org). We've recovered her position records and her route is shown in this video.
We don't have good sea-ice records for 1879, so the sea-ice overlay is from exactly 100 years later (1979-81) - taken from HadISST via ERA-Interim.
