On 26th September 2016 the MODIS sensor on The TERRA satellite captured this beautiful image of South Georgia, with Iceberg A66 drifting past. Iceberg A66 passing South Georgia captured in a MODIS image on the 26 September 2016. The image is available on a KML file on the MODIS Websites. The iceberg A66 is about […]
This post starts with that carboncounter_ fellow. He tweeted last night: https://twitter.com/CarbonCounter_/status/288423035533414400 I said I had and that I was impressed with how easy it was. To my surprise a couple of people chimed in they hadn’t got theirs or that they didn’t know it was happening. my understanding is that they are rolling it […]
Mark Brandon • December 21, 2012 On twitter this pm is a not unexpected, but rather interesting looking opportunity for those who are confident about their leadership abilities. [news] NERC seeks new Director for BAS: NERC is looking for a new BAS director; full details are available on th… http://t.co/eCHWDIsv — British Antarctic Survey 🐧 […]
The extent and thickness of the Arctic sea ice is decreasing for every month of the year. But looking at straight lines on graphs with a relentless downward trend it’s easy to lose the geographic sense of what is happening. The red areas in the plot below show where ice was absent on 3 March […]
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 […]
Quick post on the Maud Polynya in the Weddell Sea that I wrote about last week. This is the sea ice data 17 September 2017, and the polynya is both clear and large. The location of the polynya over Maud Rise. Sea ice data from DMSP SMMI. An enlargement of the polynya shows that it is […]
So I was at this award ceremony, like I usually am. And….. Getting THE Innovative Teacher of the Year Award 2012 Surprising stuff, and a huge honour. In the picture are from L-R David Walliams, Me, Professor David Gibson, and Professor Craig Mahoney. The other five people shortlisted are all clearly amazing teachers, so I have no idea […]
I was interested in how long the polynya I blogged about yesterday had existed. I made a gif of the previous months sea ice data. The sea ice extent in Pine Island Bay 11 September to 10 October 2016. Data from DMSP SSMI. The development of the polynya can be seen in the growth of the […]
Mark Brandon • January 31, 2014 In the previous post I made a plot of Antarctica and compared it to the size of Europe. I made the throwaway point that it was unreasonable to imagine Antarctica as being characterized with one climatic zone. It is not all the “coldest and windiest place” on Earth. I […]
Mark Brandon • May 15, 2017 Approaching the middle of May and well into the Arctic sea ice retreat we can see that the sea ice extent (area of ocean with at least 15% sea ice) is still well below the mean over the satellite record. Arctic sea ice extent to 53 May 2017 from […]
I very much like looking at the AQUA and TERRA MODIS sensor images every now and then. Today I saw this beautiful image off the southern tip of Greenland which was captured on 23rd February 2015. Sea ice off Cape Farewell, Greenland What you are looking at are three different white things: snow on Greenland, […]
I was asked “what is an easy way to get a satellite image into Google Earth?”. Once I explained how I do it I thought it may be of interest to others. NASA have provided a really excellent web interface to some of their visual data called Worldview. The Worldview description puts into perspective how […]
[This is a post bringing together things I have done elsewhere whilst learning how to use this platform.] I am a huge fan of the Natural Environment Research Council, and used to work for the British Antarctic Survey. It is a fact that in the UK at the moment the community has some very tough […]
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 […]
