On the expedition in the Gerlache Strait, biologist Emil Racoviță made several discoveries, including a flightless midge fly that was later formally named Belgica antarctica by the Belgian entomologist Jean-Charles Jacobs. [1] The Gerlache Strait has spiky blue icebergs, and is widely considered a great spot for whale-watching.
Icebergs may also appear blue due to light refraction and age. Older icebergs reveal vivid hues of green and blue, resulting from a high concentration of color, microorganisms, and compacted ice. [5] An iceberg of “electric blue” colour in the waters off Sermilik fjord near Greenland in 2009 was named by locals the "blue diamond". [6]
The International Association of Antarctica Tour Operators (IAATO) was founded in 1991 by seven companies. The primary goal of the association is to "advocate and promote the practice of safe and environmentally responsible private-sector travel to the Antarctic". [1] Since the group's inception membership has grown to over 100 members.
The split of the A38-B iceberg is recorded in this series of images. The iceberg was originally part of the massive A-38 iceberg, which broke from the Ronne Ice Shelf in Antarctica [3] B-15A: 6,400 2002 Northern edge of Iceberg B-15A in the Ross Sea, Antarctica, 29 January 2002: A-68: 5,800 175 50 2017 Calving crack in the Larsen C ice shelf [2 ...
The camp is operated by Antarctic Logistics & Expeditions LLC (ALE), a company that provides expedition support and tours to the interior of Antarctica. [ 2 ] [ 3 ] [ 4 ] The camp is situated near Union Glacier Blue-Ice Runway SCGC a rare, naturally occurring, blue ice runway [ 5 ] that allows wheeled jet cargo aircraft to land.
A blue-ice area is an ice-covered area of Antarctica where wind-driven snow transport and sublimation result in net mass loss from the ice surface in the absence of melting, forming a blue surface that contrasts with the more common white Antarctic surface. Such blue-ice areas typically form when the movement of both air and ice are obstructed ...
The blue colour will not be seen again until the ice breaks or turns over to expose ice which air could not reach. For example, lucky tourists at Tasman Glacier, New Zealand in January 2011 saw an iceberg roll over to reveal startling blue ice, kept from air by staying underwater for months since the iceberg calved. [2]
A23a is a large tabular iceberg which calved from the Filchner–Ronne Ice Shelf in 1986. It was stuck on the sea bed for many years but then started moving in 2020. As of January 2025, its area is about 3,500 square kilometres (1,400 sq mi), which makes it the current largest iceberg in the world.
