‘Lower sea ice extent means that ocean waves will pound the coast of the giant ice sheet, further reducing ice shelves around Antarctica’ Antarctic sea ice hits new record low in 2023 Skip to ...
‘There is some concern that this may be the beginning of a long-term trend of decline for Antarctic sea ice’ Antarctic sea ice hits ‘record-smashing’ new winter low, data shows Skip to ...
(Reuters) -Sea ice that packs the ocean around Antarctica hit record low levels this winter, the U.S. National Snow and Ice Data Center (NSIDC) said on Monday, adding to scientists' fears that the ...
The earthquake occurred at a shallow depth and had a moment magnitude of 8.1, with its epicentre being located roughly 250 km (155 mi) south of the boundary between the Antarctic and Australian plates. [8] The earthquake ruptured in a sinistral (left lateral) strike-slip manner, oriented east–west for a length of roughly 200 km (124 mi). The ...
The Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of Antarctica in winter.It peaks (~18 × 10^6 km 2) during September (comparable to the surface area of Pluto), which marks the end of austral winter, and retreats to a minimum (~3 × 10^6 km 2) in February.
Tsunami activity along the Pacific coast persisted until 20 January. The tsunami measured taller than 2 m (6 ft 7 in) at Ensenada, Baja California. Sea level disturbances were recorded at the coast of the Gulf of Mexico and Caribbean Sea. The shockwave-triggered meteotsunami had a maximum wave height of 0.377 m (1 ft 2.8 in). [130]
Antarctica’s vast expanse of sea ice regulates Earth’s temperature, as the white surface reflects the Sun’s heat back into the atmosphere. Record low sea-ice levels around Antarctica ...
Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey (BAS). The base was established in 1956 to study the Earth's atmosphere . Measurements from Halley led to the discovery of the ozone hole in 1985. [ 3 ]
