Want to explore never-before-seen places in Antarctica? These robots took humans to previously unreachable ice caves.
Researchers sent robots deep into the frozen continent and got unprecedented close-up views beneath Antarctica’s ice. Among the goals: add more nuanced data to climate models.Glaciologists are using robots to capture close-up views of ice shelves, floating platforms of ice that slow down the flow of ice into the ocean. They can use the measurements robots collect to improve climate models that predict sea-level rise.Researchers from the U.S.
Researchers monitor Icefin as it makes its way into the ocean, through different layers. The very top, 230-foot-deep layer transitions from loosely packed snow into glacial ice. The remaining 1,700 feet of ice is below sea level.Icefin scans an underwater crevasse, or cave-like crack. The two vertical white lines coming from the center are the crevasse walls, captured by sonar. Ocean water is so cold at these depths that it’s actively freezing.Marine ice has a greenish tint to it.
