The sea beneath Arctic and Antarctic ice holds many secrets. These scientists dive deep to find out - AP News

Scientists are conducting deep-sea dives beneath Arctic and Antarctic ice to study marine ecosystems and gather data about these extreme polar environments. The research targets regions that remain largely unexplored due to harsh conditions and difficult access, making direct observation rare and valuable. These expeditions aim to understand what marine life exists under the ice and how polar ecosystems function, data critical as climate change accelerates ice loss in both regions. The findings could reveal species and ecological relationships previously unknown to science while providing baseline information about polar ocean health. Such research helps scientists assess how rapidly changing ice conditions might affect the organisms and food webs that depend on these remote underwater habitats.
