A remotely-operated underwater vehicle was used to map the ice, ocean, and seafloor conditions near the point where the floating Ross Ice Shelf meets the seafloor, also known as the grounding line. The study identified refreezing crevasses and geomorphological signatures of past grounding line retreat.
