After reaching the second-lowest extent ever recorded last month, sea ice in the Arctic has begun to refreeze in the face of autumn temperatures, closing both the Northern Sea Route and the direct route through the Northwest Passage. This year marked the first time since satellite measurements began in the 1970s that the Northern Sea Route, also known as the Northeast Passage, and the Northwest Passage were both open at the same time for a few weeks. "NIC analysis of ESA's Envisat and other...

Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. This animation is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced...

The European Space Agency is about to launch the most sophisticated mission ever to investigate the Earth's gravitational field and to map the reference shape of our planet "“ the geoid - with unprecedented resolution and accuracy. The Gravity field and steady-state Ocean Circulation Explorer (GOCE) will be placed onto a low altitude near sun-synchronous orbit by a Russian Rockot vehicle launched from the Plesetsk Cosmodrome in Northern Russia, some 800 km north of Moscow. Lift-off...

Following a formidable 106-day trek across the Arctic, which ended with the two Arctic Arc expedition members relying on Envisat images to guide them safely through disintegrating sea-ice, intrepid polar explorer Alain Hubert recently visited ESA to handover a unique set of snow-depth measurements.To coincide with the launch of the International Polar Year (IPY) 2007-2008, Alain Hubert and fellow explorer Dixie Dansercoer ventured out onto the sea-ice to embark upon a trek from Siberia to...

An international group of scientists has swapped their comfortable offices for one of the most inhospitable environments on the planet to carry out a challenging field campaign that is seen as the key to ensuring the data delivered by ESA's ice mission CryoSat will be as accurate as possible.The scientists, mainly from Denmark, UK, Germany and Canada, are currently in the middle of CryoSat Validation Experiment (CryoVEx) 2008, an extensive three-week experiment program in the far north of...

The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday. The statement was released during a five-day conference held at ESRIN, ESA's Earth Observation Centre in Frascati, Italy, in which operational ice experts from Europe and North America gathered to discuss the state of the polar regions. "In September 2007, the Arctic sea...

The area covered by sea ice in the Arctic has shrunk to its lowest level this week since satellite measurements began nearly 30 years ago, opening up the Northwest Passage "“ a long-sought short cut between Europe and Asia that has been historically impassable. In the mosaic image above, created from nearly 200 images acquired in early September 2007 by the Advanced Synthetic Aperture Radar (ASAR) instrument aboard ESA's Envisat satellite, the dark gray colour represents the ice-free...

Two Belgian explorers currently nearing the end of a staggering 2,000 km trek across the Arctic Ocean were recently guided through hazardous conditions using observations from Envisat, as sea ice in the Lincoln Sea began to break up unexpectedly. Throughout the Arctic Arc expedition, which marks the International Polar Year, Alan Hubert and Dixie Dansercoer have been collecting snow-depth data for ESA's CryoSat-2 mission. As seasoned polar explorers, they are used to dealing with the...

As climate change continues to make headlines across the world, participants at the 2007 Envisat Symposium this week are hearing how Earth observation satellites allow scientists to better understand the parameters involved in global warming and how this is impacting the planet. The cryosphere is both influenced by and has a major influence on climate. Because any increase in the melt rate of ice sheets and glaciers has the potential to greatly increase sea level, researchers are looking to...

It is perhaps an unlikely combination "“ an international team of scientists stationed in Svalbard, Norway and two polar explorers crossing the North Pole on foot. Both teams, however, are currently part of a common effort to collect vital data on the ground and from the air in support of ESA's ice mission CryoSat-2. The CryoSat-2 mission, due for launch in 2009, will provide highly accurate information on changing marine and land ice thicknesses over the entire north and south polar...
