Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years.
Earlier this month Ted Scambos of the University of Colorado alerted BAS glaciologists David Vaughan and Chris Doake to images from the NASA MODIS satellite. Meanwhile, in Antarctica Argentinian glaciologist Pedro Skvarca, realised something was happening to the ice shelf and mobilised an aircraft to obtain aerial images confirming the satellite data. While the collapse was still occurring the BAS research ship RRS James Clark Ross navigated her way through the armada of icebergs to obtain photographs and samples.
Over the last month the 200-m thick ice shelf collapsed into small icebergs and fragments. Pooling these new observations scientists will determine when such an event last happened and which ice shelves are threatened in future.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
