New satellite images show the extreme melting that has taken place on the critical Greenland ice sheet, according to researchers. The sheet is a mass of glacial land ice and is an integral part of ...
The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about 0.06 millimetres (0.0024 in) per year, or roughly 4 percent of the 20th century rate of sea level rise. [15] Jakobshavn Isbrae retreated 30 km (19 mi) from 1850 to 1964, followed by a stationary front for 35 years.
The Greenland ice sheet is an ice sheet which forms the second largest body of ice in the world. It is an average of 1.67 km (1.0 mi) thick, and over 3 km (1.9 mi) thick at its maximum. [ 2 ] It is almost 2,900 kilometres (1,800 mi) long in a north–south direction, with a maximum width of 1,100 kilometres (680 mi) at a latitude of 77°N ...
After digitizing thousands of archived paper images dating back to the 1930s, Larocca’s team combined them with satellite images of Greenland today to measure how much its frozen landscape has ...
Zachariae Isstrom (Danish: Zachariæ Isstrøm; Isstrøm being the Danish word for ice stream) is a large glacier located in King Frederick VIII Land, northeast Greenland. This glacier was named by the Denmark expedition 1906–08 after Georg Hugh Robert Zachariae (1850–1937), an officer of the Danish Navy .
The National Ice Center named the new iceberg, the Petermann Ice Island (2010) [13] to differentiate it from a similar calving event two years earlier which produced Petermann Ice Island (2008). That island was tracked by the Canadian Ice Service for over a year as it travelled out into Nares Strait and south through Baffin Bay before losing ...
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
Hiawatha Glacier is a glacier in northwest Greenland, with its terminus in Inglefield Land. [1] [2] It was mapped in 1922 by Lauge Koch, who noted that the glacier tongue extended into Lake Alida (near Foulk Fjord). [3] Hiawatha Glacier attracted attention in 2018 because of the discovery of a crater beneath the surface of the ice sheet in the ...
