Strange Coastal Ice Pack is Causing a Hazard for Ships

In spring 2017, the Canadian Coast Guard had to redirect its research icebreaker, CCGS Amundsen, off its scientific research course to perform search and rescue and ice escort activities off the coast of Newfoundland. The ice cover there is moving, and thick multiyear sea ice is transporting from its usual locations in the Lincoln Sea and Canadian Arctic Archipelago to

Computer Simulation Counters Flooding on Coral Reef Coasts

Scientists have developed a computer simulation tool to predict short-term flood hazards on coral-reef-lined coasts and to assess longer-term impacts from climate change. The assessments will provide input that helps estimate societal or economic risk and damage from such flooding. The tool can be used to play “what-if” games and ask questions such as, “how will flood risk change if

Antarctica’s Dotson Ice Shelf is Melting from Below

The European Space Agency’s CryoSat satellite and its Copernicus Sentinel-1 missions have been used to measure subtle changes in the elevation and flow of ice shelves that, in turn, reveal how huge canyons are forming underneath. Warm bottom ocean water is entering the cavity under Antarctica’s Dotson ice shelf and is stirred by Earth’s rotation. This is causing one side
