  A new record low could soon be set for ice in the Arctic. The past five years have seen the lowest extent of sea ice since satellite measurements began in the 1970s. Earth observing satellites make it possible to measure the amount of sea ice in inaccessible areas such as the Arctic. This year, the extent of Arctic sea ice is comparable to the record low set in 2007. According to scientists at the University of Bremen in Germany, sea ice extent in early September has...

The European Space Agency (ESA) released the first map of sea-ice thickness from its CryoSat mission Tuesday at the Paris Air and Space Show. The CryoSat spacecraft sits at an altitude of 434 miles above the Earth delivering precise measurements to study changes in the thickness of Earth's ice. ESA said that in order to fully understand how climate change is affecting the polar regions there is a need to determine exactly how the thickness of the ice is changing. CryoSat initially launched...

The research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association returned to Bremerhaven from a six-week expedition in the high Arctic on May 6. Joint flights with aircraft of the European and American space agencies (ESA and NASA) were a novelty in sea ice research. Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the international team...

ESA's CryoSat team working on the Greenland ice sheet has been honored with a visit from a Dutch delegation including HRH Prince of Orange. The visit is part of a tour to learn more about climate change in polar regions and consequences for the environment. Prince Willem-Alexander's visit to Greenland was at the invitation of the World Wide Fund for Nature-Netherlands. The delegation included Johan van de Gronden, CEO of WWF-NL, Robbert Dijkgraaf, President of the Royal Dutch Academy of...

A carefully executed operation to validate data from CryoSat has shown what can be accomplished when ESA, NASA and others join forces to further our understanding of how the fragile polar environment is responding to climate change. In support of ESA's CryoSat ice mission, which was launched a year ago to monitor changes in ice thickness, a grueling validation campaign is being carried out in one of the most inhospitable environments on Earth. The one-month Arctic expedition is a major...

To guarantee ESA's CryoSat mission is delivering the best data possible, scientists have set out on a major expedition to the Arctic "“ part of a collaborative effort between ESA and NASA to gather ice measurements as the satellite orbits above. CryoSat was launched a year ago today to monitor the changes in the thickness of marine ice in the polar oceans and in the vast ice sheets that blanket Greenland and Antarctica. Orbiting closer to the poles than any other satellite and carrying...

Scientists can now tap into a flow of new data that will help to determine exactly how Earth's ice is changing. This information from ESA's CryoSat mission is set to make a step change in our understanding of the complex relationship between ice and climate. Considering the loss of the original CryoSat satellite during launch in 2005, scientists around the world have had a long wait for information on ice thickness "“ making the release even more of a milestone for the mission....

The Cryosat-2 spacecraft has provided a new map of ocean circulation across the Arctic basin. The spacecraft's primary mission is to measure sea-ice thickness, which has been in sharp decline in recent decades. However, Cryosat's ability to map the shape of the sea surface will allow scientists to determine if Arctic currents are changing as a result of winds being blown more easily on ice-free waters. "Nobody really knows how the Arctic is going to behave as the ice retreats, but we do...

Scientists from around the world have been hearing about the latest results from ESA's new GOCE, SMOS and CryoSat Earth observation missions at the biggest scientific gathering of the year. Attracting around 18 000 scientists, researchers, teachers, students and consultants to review developments in Earth and space science, the annual American Geophysical Union (AGU) Fall Meeting is an unparalleled opportunity for participants from around the world to share and discuss their...

Although finding a successor to the Kyoto Protocol is a major item on the agenda at the 2010 UN Climate Change Conference in Cancun, Mexico, delegates are also working hard to establish an international climate monitoring system. In order to effectively respond to climate change challenges, decision-makers need scientifically based climate knowledge. It is the job of the Subsidiary Body for Scientific and Technological Advice (SBSTA) to make sure that the Conference of the Parties (COP)...
