OMG：冰之美

NASA’s Oceans Melting Greenland, or OMG, airborne mission found that most of Greenland’s glaciers that empty into the ocean are at greater risk of rapid ice loss than previously understood. OMG’s six-year field campaign studied the ocean’s role in glacial ice loss by gathering precise measurements of ocean depth, temperature, and salinity in front of more than 220 glaciers. The mission’s goal was to clarify our understanding of sea level rise over the next 50 years. This photo of Apusiaajik Glacier was taken near Kulusuk, Greenland, on Aug. 26, 2018, during OMG’s field operations.

NASA的海洋融化格陵兰岛（OMG）空中任务发现，陵兰岛的大多数冰川流入海洋的冰迅速融化的风险比以前了解的要大。OMG为期六年的实地考察活动通过收集220多个冰川前的海洋深度、温度和盐度的精确测量数据，研究了海洋在冰川融化中的作用。该任务的目标是阐明我们对未来50年海平面上升的理解。2018年8月26日，OMG在格陵兰的库卢苏克附近拍摄了这张阿普西亚吉克冰川的照片。
