In an incredible discovery, polar scientists have sighted marine life on the ocean floor beneath a huge Antarctica ice shelf, an area previously believed to be uninhabited. Planning to collect sediment samples, scientists from the British Antarctic Survey (BAS) lowered a camera into a borehole in the Filchner-Ronne Ice Shelf on the southeastern Weddell Sea. The camera descended through 900 meters (approx. 0.5 miles) of solid ice before exiting into the depths of the Antarctic far below. The temperature on the pitch-dark ocean floor, untouched by sunlight, registered -2.2 degrees Celsius (approx. 28 degrees Fahrenheit). As the camera bounced off a boulder, it captured footage of two different types of filter-feeding sea sponges affixed to a rocky formation. The sponges, 160 kilometers (approx. 99 miles) further from previous sightings by the researchers, CNN reports, are the first stationary marine life to be documented in the area. “This discovery is one of …
