In 2013, the research team returned to Sermilik Fjord to find that a large passing iceberg had pushed down the SF1 mooring’s top float to depths where increased water pressure caused it to implode. The researchers dragged the bottom of the fjord to recover the mooring. Its instruments survived the trauma and recorded data that helped the researchers learn about ocean’s circulation near the glacier. (Fiamma Straneo, Woods Hole Oceanographic Institution)
