Short summary
Contrary to expectations, Antarctic sea ice cover has been increasing in area during the last three decades. In order to put these trends into a wider context this paper analyses direct observations of sea ice, recorded in ships' logbooks during the Heroic Age of Antarctic Exploration (1887–1917) for the first time. It shows that the sea ice was significantly further north in the Weddell Sea during the period but comparable to the present day in other sectors.
