It is called Icefin and it is mapping some never-before-witnessed regions.
A U.S.-New Zealand research team was able to witness evidence of “ice pumping” in the Antarctic ice shelf– a process never before directly observed in an ice shelf crevasse, at a distance of nearly 1,900 feet near where the surface of the Ross Ice Shelf meets Kamb Ice Stream.
by providing the first high-resolution views of ice, ocean, and sea floor interactions at contrasting glacier systems on the West Antarctic Ice Sheet.“Antarctica is a complex system, and it’s important to understand both ends of the spectrum – systems already undergoing rapid change as well as those quieter systems where future change poses a risk,” Britney Schmidt, associate professor of astronomy and earth and atmospheric sciences in A&S and Cornell Engineering said.
So far, Icefin has mapped five crevasses and parallel sets of ridges on the sea floor that the researchers believe are impressions left behind by ice shelf crevasses – and a record of 150 years of activity since the Kamb stream stagnated. “We can look at those sea floor features and directly connect them to what we saw on the ice base,” saidLawrence, the paper’s lead author, now a program manager and planetary scientist at Honeybee Robotics. “We can, in a way, rewind the process.”
NASA supported the research through the Planetary Science and Technology from Analog Research program’s Project RISE UP , and the Future Investigators in NASA Earth and Space Science and Technology program.
