Scientists Get a Close-Up Look Beneath a Troubling Ice Shelf in Antarctica.
The star of the show was the underwater robot, called Icefin, which was designed, built and operated by Dr.
Schmidt and her team.
A cylinder 9 inches in diameter and about a dozen feet long, it carries cameras, sonar and other instruments, as well as thrusters for propulsion.
Schmidt slowly “drove” the device via a long tether that carried signals from the surface.
“Getting to see the ice for the first time was really powerful,” Dr.
“There were some really intense experiences.”

Among them was driving the robot toward the grounding line, where the water column between the ice and bedrock narrowed to barely more than the diameter of Icefin itself.
Squeezing into that space “ was pretty remarkable and very exciting,” she said.
“And it was also terrifying.”
Icefin explored crevasses and steep-sided terraces on the underside of the ice, and found rapid melting there, as the near-vertical orientation of the sidewalls allowed mixing and brought more heat to bear on the ice.
