A glacial meltwater stream flowing down to Whalers' Bay in Port Foster, Deception Island. Bark Europa can be seen in Whalers' Bay. The dark, partly snow covered ridge beyond it is the far side of Port Foster, the flooded caldera. Apart from along the Antarctic Peninsula, meltwater streams are rare in Antarctica. Most of the ice sheet surface is too cold, even in summer, for substantial surface melting to occur. Despite this, parts of the ice sheet are now losing significant amounts of ice as a result of changes in ocean circulation that have brought increased amounts of relatively warm water into contact with the ice where it flows into the ocean on a bed that is far below sea level.
Two members of the voyage crew point towards the mainland of the Antarctic Peninsula at the vantage point on the Deception Island caldera rim from which Nathaniel B Palmer first sighted it in 1820. There must have been much better visibility on that day, as we could barely see anything more than a couple of kilometres away.
View of Neptune's Bellows, the narrow entrance to the Port Foster flooded caldera, from the "window" on the caldera rim from which Nathaniel B Palmer first sighted the mainland of the Antarctic Peninsula. A sea stack in the upper central part of the photo guards the eastern side of the entrance.

Day 5 (continued) of my voyage to the #Antarctic Peninsula on the #tallship #BarkEuropa: second landing, at Whalers' Bay, Deception Island, South Shetland Islands. From the landing site we walked up a valley to a depression in the caldera rim.
