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 marine ecosystem that’s been hidden beneath […]
Being interested in the Weddell Polynya I plotted some time series data from 1 September 2017 to 23 November 2017. On the left-hand panel, you can see the see the sea ice concentration, on the right-hand panel, the anomaly of the concentration each day compared with a mean from 1989-93. The Weddell Polynya is the […]
The Amundsen Sea currently has some very large polynya. In front of the Dotson, Getz and Pine Island ice shelves they are clear in the satellite data.

[This is a post bringing together things I have done elsewhere whilst learning how to use this platform.] Back in July 2012 the global news media went very big on a story on the Melting of Greenland. The original BBC Greenland Melting story I got involved in a discussion on twitter about it, with lots […]
The polynya I saw forming in early February is still clear, and very large in the Southern Weddell Sea. 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 Terra MODIS […]
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 […]
The MODIS sensor satellite imagery is showing a beautiful and evolving large plankton bloom in the Chukchi Sea at the moment. Plankton bloom in the Chukchi Sea, as seen in the MODIS sensor on 23 June 2015. Alaska is on the LEFT and Russia the RIGHT. The image is looking SOUTH. The plankton are the […]
The summer of 2016 saw the joint second lowest Arctic sea ice extent. But in the middle of October unusual Arctic weather has led to it becoming the lowest extent. At the same time, Antarctic sea ice extent has also reached record lows. Tamino has a simple and clear post about what a surprising thing […]
A recent interaction with a scientist left me both bemused, and if I am honest a little bruised. He described twitter as “that rather infantile social network system.” Co-incidently Peter Gibbs, an ex-Antarctican, BBC broadcaster and weather forecaster asked me about media work as a scientist – but given my recent interactions I flunked the […]

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 […]

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 […]
