100 years on … the spirit of international colla...

From Michael (NASA), the Arctic, 29 March Today marks the centennial of Sir Robert Falcon’s death on the Ross Ice Shelf on March 29, 1912. There are many commemorative events taking place around the world today to remember the scientific accomplishments of the Terra Nova Expedition. The most prominent of all events is a National Service of Commemoration for Captain Scott and the Pole Party at St. Paul's Cathedral in London, with our own Seelye Martin participating as a guest of honor. In 2008, I had the privilege to visit Captain Scott's historic Terra Nova Hut on Cape Evans in Antarctica, and the geographic South Pole, where the National Science Foundation has...

Time to draw breath

From Seymour, Katharine & Rosie (UCL) in Alert, 18 April   As the main activities in Alert are winding down, it's time to draw breath before the next leg of the campaign kicks off in Svalbard and Greenland. The UCL team has been looking back at what has been achieved over the last week. After arriving in Alert, bad weather initially prevented the aircraft from flying to the experiment sites. However, a break in the weather and safe arrival of the DTU team with the precious ASIRAS instrument on 13 April meant that everything was in place to get the campaign off the ground. The break in the weather held so that they...

Great day for sea-ice research as ESA and NASA work tog...

From Michael (NASA), over Alert, 15 April Today’s flight was a coordinated effort between ESA’s CryoVEx campaign and NASA’s Operation IceBridge. The CryoVEx 2011 teams are currently operating from Canadian Forces Station (CFS) Alert and have installed corner reflectors and GPS buoys on the sea ice north of Alert yesterday using a Kenn Borek Twin Otter. Today and tomorrow, teams from the University College London and the University of Alberta are on the ice making in situ measurements along the profiles between the corner reflectors.

NASA IceBridge – clear but bumpy over southeast G...

From Michael (NASA) Greenland ice sheet, 11 April On April 11, NASA's IceBridge campaign finally got the clear weather necessary to fly over glaciers in southeast Greenland. Typically, this area is shrouded in cloud, but strong winds from the Greenland ice sheet can clear the cloud – but these winds and the rugged coastal topography cause a lot of air turbulence. So, with clear skies came winds of up to 70 knots, which made for a bumpy ride over the calving front of glaciers such as Gyldenlove seen here. Despite the difficult conditions we were able to survey all planned glaciers in the cloud-free area south of 65N. The amount of windblown...

Up and away

From Malcolm (ESA), NL on 8 April Just leaving ESA in the Netherlands for my flight to Alert in northern Canada to start the campaign – which has to be one of the biggest I've organised in my 10 years at ESA. The two planes we have dedicated to the campaign will arrive this weekend along with other team members from Europe and Canada. So, hopefully we'll be kicking off with the first flights on Monday. We've got a Twin Otter arriving from the Technical University of Denmark that carries the ASIRAS instrument. ASIRAS is an airborne instrument that was developed specifically to mimic the radar altimeter on the CryoSat satellite. In...
