Missing Robot In The Antarctic Returned With Terrifying Data

An ocean robot lost in Antarctica returned with crucial data on the Denman Glacier, revealing it could cause global sea levels to rise by almost 5 feet. The robot measured salinity and temperature beneath the Denman and Shackleton ice shelves, providing the first oceanographic measurements under an East Antarctic ice shelf. This data is critical for understanding the impact of climate change on Antarctic glaciers and predicting future sea level rises.
