A team of scientists is heading to the Arctic on a research mission deemed too dangerous for humans to go alone. The team will use an underwater robotic vehicle (AUV) to help them understand the extent of melting from glaciers. The Scottish Association for Marine Science (SAMS) in Oban, will send the AUV to one of the most hostile environments on the planet. The robot will gather data and take measurements such as temperature and salinity from as deep as 100m (330ft). It will help scientists learn more about the effect of meltwater on a process known as "calving", which can cause large pieces of ice to break off the glacier edge.
