and Its Approaches

ABSTRACT. Descriptions of sea i c e in Hudson’s Bay Company ships ’ log-books and tradiig post journals are used to reconstruct sea ice conditions in Hudson Bay, James Bay, and Hudson Strait in the summer of 1816. The results demonstrate that exceptionally late sea ice dispersal occurred in J a m e s Bay, southeastern Hudson Bay, and at the western extremity of Hudson Strait. A relatively intense flow of i c e in the Labrador current occurred at the eastern extremity of Hudson Strait. These patterns of ice behaviour are indicative of the prevalence of northwesterly atmospheric circulation over this region in the summer of 1816. Key words: sea ice, Hudson Bay, Hudson Strait, 1816, ships ’ log-books RkWM6. Les archives de La Compagnie de La Baie d’Hudson ont W mnsult6es pour reconstwire les conditions des glaces de mer.
