Mark Brandon • November 24, 2017 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 […]
Mark Brandon • October 15, 2024 I love looking at satellite images of the Antarctic and picking out the icebergs. In the last few years we have had great stories about the giant icebergs A68 in 2020, A76 in 2022 and most recently A23a currently in the Southern Scotia Sea. At the moment there are […]
Mark Brandon • February 21, 2013 It’s a little odd to me when people refer to the polar regions as being something to do with the “sounds of silence”. I have never thought of peace and quiet when I am on sea ice. You see the sea ice is always moving, (except when it is […]
Mark Brandon • October 26, 2017 As daylight has returned to Antarctica it is straightforward to pick out polynya forming on the edge of the Antarctic continent. This one by the Stange Ice Shelf and Rydberg Peninsula caught my eye. It is a latent heat polynya formed as the winds push the sea ice away […]

Mark Brandon • March 1, 2013 As a marine scientist I have always had an obsession with the sea and what it is doing. You can see that by looking at the photos section of this site, or my flickr stream. A couple of weeks ago Dr Ian Brooks (Leeds) tweeted to a colleague, a […]
On 25th April 2019, the Arctic sea ice extent was 1.2 million km² below the 1981-2010 mean. Sea ice in the Arctic currently ~1.2 million km² below the 1981-2010 mean. 25 April 2019. If we compare the sea ice extent today, with the mean sea ice extent for the period 1989-93, the red colours show […]

Mark Brandon • December 23, 2016 It’s been quite a year in the Arctic. Over the winter 2015/6 we had the strongest and coldest Arctic polar vortex of the last 68 years. This contributed to a low maximum in Arctic sea ice extent. At that stage only the locals and the scientists were looking, and I […]
Mark Brandon • May 15, 2017 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) […]
Mark Brandon • November 14, 2016 The Prince Gustav Channel was covered by an ice shelf which collapsed in the 1990’s, and for many years it was possible to sail a ship around James Ross Island. Recently it has been covered with sea ice frozen to the land – we call this fast ice, and […]
Mark Brandon • July 30, 2015 Yet more beautiful MODIS imagery showing some wonderful patterns in a plankton bloom in the Barents Sea. Plankton patterns in the Barents Sea The screen grab is from the 250m resolution imagery, and the whole arctic panel shows just where the bloom is located. The Arctic on 29 July […]
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 […]
