The #Mawson#iceedge in November. Floating first-year #seaice is visible at the right; it extends in a continuous unbroken sheet all the way in to the #coast, about 80 km further south. This ice is held "fast" by its attachment to the coast, and is not free to drift away into the #openwater seen at the right. A few small #icebergs are visible in the open water. The first #resupply#ship of the summer would normally break its way through any drifting #packice further out, so it could conduct #helicopter flights in to the station from the ice edge. If conditions were good, heavier cargo was sometimes taken ashore by #hagglunds vehicles that would drive out to the ship over the fast ice. Photo scanned from a #35mm#ektachrome#slide original.
Soon... This bay is still chocked full of sea ice - looking forward to open waters .
This photo was taken in July and the rough pack ice was still hanging around just offshore .

Happy #WorldPenguinDay ! They may wear their finest tuxedos everywhere they go, but Penguin's habitats are under threat. Sadly for penguins that make Antarctica, the sea ice melting season has extended by as much as 3 weeks in recent decades. Less ice means less habitat for penguins and the loss of critical food, such as shrimp-like krill, which depend on polar ice to reproduce. #climatechange#seaice#penguin#antarctica
While in Wellington, NZ we had the chance to hear a presentation by Dr. James Renwick, professor of Environmental & Earth Sciences at Victoria University. His talk was titled "Climate Change: The Latest Science" and he explained just that to a packed and silent room. His main overview was of the most recent insights and projections regarding sea ice and ocean levels. The graph shown here is not one regarding temperature but sea levels. Renwick explained that a 2-3°C temperature increase in the near future would result in a 2-5 meter increase in sea levels in 200 years time. The low end of that projection is modeled after a full global commitment to the Paris Agreement - starting now - which is represented by the blue line on the graph. Despite the bleak and empty feeling inside most of his audience, Renwick remained staunchly optimistic. "We may not be able to correct this entirely, but our choices now will have a profound impact on the future" he said. "We can make a difference but we have to get serious and we have to start now."
