This was the live coverage of the whole event. Please discuss below.
On the ESA homepage it says:
Watch online: CryoSat resultsLive from the Royal Society in London, watch the unveiling of the first map of the winter 2010–11 changes in Arctic sea-ice thickness measured by ESA’s CryoSat satellite. Join the event via live web stream Tuesday starting at 07:30 GMT (09:30 CEST – 08:30 UK time).
9.31: I have just managed to connect and am waiting for the broadcast to start.
9.32: Broadcast has started.
9.35: This is the audience:
9.37: It has started. David Williams from the UK Space Agency is doing a short introduction. Followed by David Willets, Minister of University and Education. Lauds the UK Space Agency, lauds Great Britain. :-)
9.45: It's Volker Liebig's turn, director of Earth Observation Programmes from ESA. Congratulates UK Space Agency with 50 year anniversary. Jumps to Arctic Sea Ice immediately, shows consecutive extent records. Shows Stroeve's graph of trend deviation from IPCC models. Arctic important for climate change, but also geopolitically and for shipping.
9.51: Turns to CryoSat. CS works perfectly, very efficient. CS has been calibrated a lot, also through NASA IceBridge. Shows last year's map, was done in a hurry. This year should be more accurate. Talks about Greenland now. Greenland will melt, question is how fast. Talks about ocean topography, use for oceanographers. Useful because it comes as close as 88 degrees to the North Pole, closer than any altimeter. Shows CS sysnergy with other ESA missions, for instance measuring salinity and ice movement. ESA is cool. ESA can do much more than any country could do by itself. There will be much more observation missions.
9.57: Now it's the turn of previous CryoSat head of mission, Principal Investigator of University College London, professor Duncan Wingham, showing the results. Thanks everyone involved in the mission. Puts the data into scientific context, example: Antarctic contribution to sea level. Talks about what they had promised in 1999 CS would do. Goals have been achieved. CS very important for Arctic Sea Ice, because of the wide interest in when it will be ice-free.
10.05: Wingham shows a 3D graphic from Antarctica. CS is the only game in town, and hopefully it stays that way until the Sentinels are up. Shows a radar echo of sea ice thickness on 20th April 2010, just ten days after the launch of CS:
10.08: Shows last year's thickness map, revealed in France last year. Cobbled it up quickly, then came the verification process. Here's another screen capture, a comparison with sonar looking up:
Capture of thin ice isn't perfect, but still quite good.
10.12: Another screen shot:
Talks about PIOMAS. Shows a volume graph, based on CryoSat data:
10.17: I'm missing a couple of things here, having to make and crop the screen shots. I don't believe he said anything about accuracy of PIOMAS. He talks a lot, will have to watch this again later on. Talks about ocean dynamic thingamajigs. CryoSat will do everything that was promised, deliver good thickness numbers, etc, that will help determine when the Arctic becomes ice-free.
10.20: Talks now as executive director of NERC. Budgets get tighter. Science gets less money, so the missions have to be efficient.
10.23: Last talk by Elizabeth Morris, from the Scott Polar Research Institute, talking about ground observations to valide CryoSat.
One final screenshot from the beginning of the talks, I believe that again is last year's thickness map:
"Variations in sea ice thickness will be seen as of 2012."
Okay, I think that was it. Time for breakfast. Will report later on this. First impression: more teasers, no new thickness maps. :-P
