\nA National Science Foundation-funded team of researchers has made a surprising discovery 2400 feet beneath the Ross Ice Shelf in Antarctica...fish, invertebrates living and thriving in the brutally cold and perpetually dark waters...\nA National Science Foundation-funded team of researchers has made a surprising discovery 2400 feet beneath the Ross Ice Shelf in Antarctica...fish, invertebrates living and thriving in the brutally cold and perpetually dark waters beneath the ice so far away from the open ocean. The team says the discovery opens new questions about the ability of life to thrive in extreme environments.

The Whillans Ice Stream Subglacial Access Research Drilling or WISSARD Team for the first time ever, drilled down to the “grounding zone”, 530 miles from the edge of the Ross Sea...where Antarctic ice, land and sea all converge. The team used a specially designed hot water drill to bore through a half mile of ice, working around the clock to collect sediment samples. While the borehole remained open, the team deployed a remotely operated vehicle or ROV called Deep SCINI into the hole. Developed at Northern Illinois University, the ROV was fitted with a number of oceanographic instruments, including a downward looking camera to record data.

The grounding zone is extremely important for the stability of the ice shelf and studying core samples from this remote area will provide scientists with clues about the mechanics of ice sheets, future changes in climate, and sea-level rise.\n
