July 16, 2018, 10:05 Washington, July 16 (Prensa Latina) NASA confirmed today that the huge A-68 iceberg is celebrating its first anniversary since it was was separated from the ice Larsen C in the Antarctic Peninsula, wedged in the waters of the Weddell Sea, barely moves.
Its large size and Weddell's dense sea ice characteristics have made it difficult for the currents, tides and winds to circulate, the US space agency confirms in a statement.
Its northern end encountered the shallow waters near Bawden Ice Rise, a rocky spur covered with ice.
On July 30, 2017, the iceberg separated from the ice front and then fractured into two pieces, called A-68A and A-68B
During this year, the first traveled a relatively short distance from the edge of the ice shelf to the sea – about 45 kilometers -, while the second is more than double this distance previous location
Data acquired from the Landsat 8 thermal infrared sensor images do not provide information to determine how long the A68 will remain blocked but show that the next route A-68B is usual for many Antarctic icebergs transported by the Weddell currents to the north, South Georgia and the South Sandwich Islands
