Two robot submarines will plunge into the Arctic next month in an effort to help Canada stake a claim to a large swath of potentially mineral-rich seafloor in the polar region. According to Larry Mayer, chief scientist of the mission, apart from the land claims, the missions have scientific significance. The Arctic maps could also have important ramifications with respect to climate modelling and climate change because the global distribution of heat is controlled by ocean currents. Where heat flows is often controlled by the sea floor.
