Mega-iceberg melt affects important marine #ecosystem

The mega #iceberg #A68A, which started out four times the size of Greater London, calved off the #LarsenIceShelf on the #Antarctic Peninsula in 2017. Scientists tracked the iceberg on its 4000 km journey across the South Ocean until it reached the sub-Antarctic island of #SouthGeorgia, where it broke up and melted over a three-month period from late 2020 to February 2021.

Mega-iceberg melt affects important marine ecosystem

Scientists have for the first time taken in-situ ocean measurements during the collapse of a giant iceberg in the sub-Antarctic. These new observations reveal how ocean ecosystems may be affected if more icebergs calve due to warmer ocean temperatures around Antarctica.

Icebergs (shed from #A68a) producing trails in low clouds north of South Georgia on 27 Jan as seen by #Sentinel2 🛰️, these ones are a few 100 m across and I guess rise 10 to 30 m above sea level (?).

Iceberg A68a collides with South Georgia shelf

Iceberg A68a has collided with the South Georgia undersea shelf and produced a bunch of more bergs.

Spot the grounded bergs. While iceberg #A68a has so far hit but not grounded on the shallow shelf around South Georgia a lot of icebergs it has shed are grinding across the shelf or are completed grounded. #Sentinel2

Iceberg gigante que se desprendeu promove espetáculo gelado na Antártida

NASA publica fotos do A-68, que se desprendeu da plataforma Larsen C e agora pode ser contemplado com melhor visibilidade
