Ice is the great feature of Antarctica. More than 12 million square kilometers of ice covers the area. About 85 percent of the ice in the world is in Antarctica. The icecap is very thick, nearly 2,400 meters. If this large amount of ice melts (融化) because of warmer weather, the ...
According to theBritish Antarctic Survey(BAS), the break occurred late on January 22, 2023, and produced a new iceberg with an area of 1550 square kilometers (about 600 square miles). TheU.S. National Ice Centerhas named it Iceberg A-81. The berg is visible in this image, acquired...
which will put it on a path that has become known as "iceberg alley," the BBC reports. That is the same current of water that famed explorer Ernest Shackleton used in 1916 to make his storied escape from Antarctica after losing his ship, the Endurance. The legendaryshipw...
Iceberg A23a boasts an area of approximately 3,900 square kilometers (1,500 square miles), making it more than twice the size of Greater London and 40 times the area of the city of Lisbon. Its impressive dimensions include a thickness of 400 meters (1,212 feet), almost twice as tall ...
B Sometime between July 10 and 12, a massive iceberg the size of the US state of Delaware broke free from Antarctica's Larsen C Ice Shelf(冰架). The crack that led to the separation was visible in the first images of the ice shelf captured by NAS A satellites in 1963. However, the...
A large wedge of ice broke from Antarctica’s Brunt Ice Shelf in late May 2024, the most recent in a series of notable icebergs spawned by the shelf in the past few years. Soon after the break, the TIRS-2 (Thermal Infrared Sensor-2) on Landsat 9 captured this pair ...
South America has the longest mountain range in the world. The Andes Mountains stretch 4,350 miles (7,000 kilometers) from Venezuela south to Chile.1 05 of 07 Antarctica David Merron / Getty Images Based on area, Antarctica is the fifth-largest continent at 5.5 million square miles (...
The detailed view shows this northward expanding rift coming within a few kilometers of the McDonald Ice Rumples and the Halloween crack. When it cuts all the way across, the area of ice lost from the shelf will likely be at least 1700 square kilometers (660 square miles). Tha...
earlier than normal. And the sea ice was at a new record low—not just by a little bit, but by a lot. The last time Antarctica’s low sea ice set a record at the end of winter was in 1986. And this year, there’s about 1.03 million square kilometers less sea ice than in ...
The intercept will occur at 240 kilometers (130 nautical miles) The mass of the satellite is 2,300 kg (5,000 pounds) The mass of the interceptor is 20 kg. (From CBO) The closing velocity will be 9.8 km/s (22,000 mph), suggesting a virtually head-on collision. The satellite ...
