This effort builds on Schmidt's ongoing interest in ocean exploration.
Antarctic robot reveals thousands of icefish nests in Weddell Sea
Scientists using a robotic explorer have discovered over a thousand organized fish nests beneath Antarctica's Weddell Sea, exposed after a massive iceberg calved in 2017. The nests, built by yellowfin noties, form geometric patterns on the seafloor and highlight a thriving ecosystem in extreme conditions. This finding underscores the need to protect the region as a marine sanctuary.
Russia charges Ukrainian biologist with treason over Antarctic protections
