NASA’s Operation IceBridge, a survey of polar ice, carried out parallel flights in the north and south poles for the first time in seven years. The mission to the Antarctic Peninsula recorded a big drop in height of the two glaciers at the south pole. The mission to the Arctic collected measurements of depleted land and sea ice at the end of the summer melting season.

In an article on the NASA website, Christopher Shuman, research associate professor at UMBC’s Geography and Environmental Systems department, faculty at UMBC’s Joint Center for Earth Systems Technology (JCET), and research scientist in the Cryospheric Sciences Laboratory at the NASA Goddard Space Flight Center, said that IceBridge’s findings are “not all that surprising given what we have observed with other sensors.”
