Icebergs

Credit: Pixabay/CC0 Public Domain British scientists are tracking two enormous icebergs that broke off from Antarctica and could intrude on shipping lanes. The smaller of the icebergs is called A81 and it's bigger than Greater London, according to the BBC. Its larger travel companion is called A76a. The Royal Research Ship Discovery inspected the latter berg as…

Crash diet alert: Antarctica’s Brunt Ice Shelf has slimmed down by about 256 billion tons. As part of a major calving event, an iceberg nearly the size of Houston, Texas, separated from the continent on Sunday, according to the British Antarctic Survey.It’s the second major iceberg break for the Brunt shelf in recent years. Aprevious one in February 2021 was, at the time, the largest known Brunt calving since satellite data collection began in the 1970s. That 2021 iceberg, named A-74, was about 470 square miles (1,270…

Comparison of the datasets: BYU/NIC in red, AWI in orange, Halley, Bouvet and Riou observations in black and Cook's cruise tracks and data points in blue. His first traverse of the Weddell Sea is a solid line; his second is dotted. For Cook, open circles mean no icebergs; small closed circles, one to three icebergs; larger closed circles, many icebergs. The circled point on 8 January 1773 marks where Cook collected fresh water from an iceberg and of…

Iceberg A-68A thickness. 2017 – 2021.Researchers recently chronicled the death throes of A-68A, one of the world’s largest-known icebergs.As soon as an iceberg is born it starts to die. Waves chip away at its edges, air thaws it from above, and water melts it from below. Scientists recently documented such death throes for one of the world’s largest-known icebergs.In July 2017, Iceberg A-68 broke from the Larsen C Ice Shelf, along the east coast of the Antarctic Peninsula. At the time, it was the largest iceberg in the…

By United Nations University – Institute for Water, Environment and Health May 26, 2022The atmosphere contains an estimated 13,000 km3 of water vapor, some of which can be captured through cloud seeding and the collection of water from fog and mist. Remote communities in Chile, Morocco, and South Africa have used vertical mesh nets to harvest fog for over 100 years, and there are viable sites for fog harvesting on every continent. Advancements in materials and indigenous knowledge have helped develop highly productive,…
