With three of my Open University colleagues: Dr Phil Sexton, Dr Pallavi Anand, and Dr Mandy Dyson, I have been working in the background on a new landmark TV series called Blue Planet 2. This incredible series has been made by the BBC Natural History Unit with the Open University as co-producers. It has seven […]
Just over a year ago in July 2017 iceberg A68 calved from the Larsen C Ice Shelf. I appeared on BBC News before it actually calved explaining what was happening. At first A68 was slow to move and as I predicted back then, it likely got stuck on the sea bed (we say “grounded”). It has […]

At the moment it is more than than 80,000 km2, although there is clearly a lot of young sea ice covering a large part of the polynya. The Weddell Sea 5 March 2017 in the […]
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 […]
Watching the sea ice extent this summer in Antarctica has been a bit surprising. The Antarctic sea ice extent has been tracking at record lows virtually the whole austral summer. We are very close now to the expected sea ice minimum, and this is where we are: Antarctic sea ice extent 12 Feb 2017 & […]
I don’t usually work on this sort of thing, but very recently I have been writing about hazards caused by the cryosphere. A major hazard is of course the avalanche – whether ice, snow, or a mixture. This video was posted on You tube (with the tag line “Courtesy Vertical Solutions”), and it shows the […]
I was enjoying my polar books the other night and came across a quote attributed to everyone’s favourite humanitarian polar explorer and scientist, Fridtjof Nansen. Fridtjof Nansen, 1915, from the George Grantham Bain Collection If I were not a Norwegian, I would be an Englishman rather than belong to any other nation Nansen is quoted […]
Captain Robert Falcon Scott “England knows Scott as a hero; she has little idea of him as a man. He was certainly the most dominating character in our not uninteresting community: indeed, there is no doubt that he would carry weight in any gathering of human beings. But few who knew him realized how shy […]
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 Dotson Getz polynya on 9 October […]
In the old days Antarctica wasn’t mapped and measured by satellites like it is now. In the past it was all about exploration. Scientists were dropped at bases by ship, and then left for at least a year – sometimes two. Very occasionally more. When winter comes the sea ice freezes up and the area […]
Today is 105 years since Roald Amundsen, Helmer Hanssen, Sverre Hassel, Oscar Wisting and Olav Bjaaland reached the South Pole. And Google have celebrated that fact with a google Doodle: Amundsen expedition South Pole Google Doodle I love the doodle. It’s beautiful art. But it falls on me to be a bit of a bore… The doodle […]
At this time of the year we should expect the Antarctic sea ice to be growing rapidly, but after the historic lows of last Antarctic summer, we can see that whilst it is rapidly advancing, the sea ice extent (the area of ocean covered by >15% of sea ice) it is still ~1 ¼ million […]
