This is the 2012 sea ice extent for both the Arctic and the Antarctic. The day of year and the calendar day are at the bottom. I chose 2012 only because it is the most recent complete year in this data set. My reason for making this video is because there have been a couple […]
I love watching the opening of a polynya in satellite data. This is North Water at the NW tip of Greenland expanding over 6 days. You can see the wind is to the SW and it is both pushing the mobile sea ice away from the fast ice of Nares Strait (the strait is named for […]
Mark Brandon • February 13, 2017 The Metropolitan Museum of Art has made more than a third of a million images both public domain and searchable online. This is one of my current favourites: An Arctic Summer: Boring Through the Pack in Melville Bay by William Bradford and painted in 1871. An Arctic Summer: Boring […]
Mark Brandon • October 13, 2016 My previous posts on Amundsen Sea Polynya and their development showed ~37,600 km2 of open water in front of the ice shelves. It is very early spring in Antarctica at this time of the year and it’s still cold. That means sea ice can still grow. This is the […]
Mark Brandon • July 28, 2017 The sea ice in the Antarctic is at minimum extent in February and expands through to mid September. This movie shows the Antarctic sea ice extent from 1 Feb to 25 July 2017. The data come from the DMSP SMMI sensor, and it shows the expansion of the sea […]

Mark Brandon • November 20, 2017 Antarctic sea ice extent remains low compared with the 1981-2010 median extent. This image shows the mean from 1989-93, the extent on 20 November 2017 and the difference between the two. Red colours imply that there is a decreased sea ice extent compared with the mean. The mean Antarctic […]
In 2012 I put together a storify using twitter and weblinks about the Greenland Surface Melt. In that story a bunch of climate scientists and I talked about whether the extreme melt seen in 2012 was a signature of global warming. The original BBC Greenland Melting story An Open Access paper by Sirpa Häkkinen and […]
Mark Brandon • April 17, 2013 I was reading my copy of Nansen’s Farthest North the other day and came across a discussion of The Jeannette Expedition which was led by Lt. Cmdr. George DeLong. Nansen wrote I wondered if people knew what a water sky was? …continue reading → Posted in At sea, Science. […]

Mark Brandon • September 30, 2014 This is a storified version of Gavin Schmidt’s talk on composition & CH4 feedbacks from Arctic sea ice loss with background information.

Mark Brandon • February 13, 2018 Iceberg A68 calved from the Larsen C ice shelf earlier this year. I wrote about before. As the berg calved it is starting to reveal a patch of seafloor that has been covered by thick glacial ice, and as the BAS press release says this has revealed: a mysterious […]
Mark Brandon • June 12, 2013 This post is quite long but stay with it. It shows how large some of the heat exchanges going on in the polar oceans can be. The picture above shows an iceberg through mist rising from the sea. It is pretty, but it is also showing is a vast […]
Predictable I know – but I do like taking photographs. Whilst I would very much put myself in the category of “snapper”, I have got a few pictures I like. The pictures accessed from this page are ones I like, or such as in the case of the Beaufort page, ones I think could be […]
