We have had the rare pleasure of open water in front of the base for a few weeks now. The open water has attracted a range of wildlife that would not always be seen here. The curious emperor penguins that Sarah described, lots of little Adélies, Weddell seals and even whales. It was quite an experience to look up from the Scott Base dining room table and see a pod of Mike whales swimming past!

The temperature is beginning to drop now and we seem to be steadily hitting -20°C and lower. The sea has been freezing over nearly every day, but then it has either washed out into McMurdo Sound or melted up until now. On Monday the sea in front of the base froze over and it looks like it is going to stay frozen this time. A whale managed to pop its head up for a moment in a melt pool yesterday, but unfortunately I think this may be the last we see of them for a few more years. Three Adélies were seen running towards Cape Armitage early this morning.


The penguin exodus and the ever shortening days seem to herald the beginning of winter and the wonderful sunrises and sunsets that it brings.
