Video PlayerClose SAN FRANCISCO, Jan. 9 (Xinhua) — U.S. scientists have found that strong El Nino events can cause remarkable ice loss in some Antarctic ice shelves while the opposite may occur during strong La Nina events, a new study revealed Monday. The study, published in the journal Nature Geoscience, discovered that a strong El Nino event caused ice shelves in the Amundsen Sea sector of West Antarctica to gain mass at the surface and melt from below at the same time. The change has led to a loss up to five times more ice from basal melting than what was gained from increased snowfall. El Nino and La Nina, which are two distinct phases of the El Nino/Southern Oscillation (ENSO), are a naturally occurring phenomenon, where water temperatures in the tropical Pacific periodically oscillate between warmer than average during El Ninos and cooler during La Ninas. The U.S. researchers examined 23 years of satellite data on the West Antarctic ice shelves and confirmed that ENSO impacts the shelves on an annual basis. They found that a strong El Nino changes wind patterns in West Antarctica, which not only brings warm ocean waters to the ice shelves, resulting in the… Read full this story
