Extensive use of time-lapse photography is used to document the changing seasons and the Antarctic landscapes. Powell had to invent many of his own camera systems to survive the extreme conditions of the deep Antarctic winter. Powell's previous work includes footage for Discovery, National Geographic, and was featured in BBC's Frozen Planet. [6]
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.
EIS imagery has appeared in time-lapse videos displayed in the terminal at Denver International Airport; in media productions such as the 2009 NOVA Extreme Ice documentary on PBS; [1] and is the focus of the feature-length film Chasing Ice, directed by Jeff Orlowski, [2] which premiered at the Sundance film festival in Utah on January 23, 2012.

On Dec. 21, 2024, the Antarctic sea ice extent was higher than on Dec. 21, 2016, but the Arctic sea ice extent was lower on that date in 2024 compared to 2016, according to government data.
Air bubbles within a deep ice core drilled in Antarctica could reveal why Earth suddenly began to experience longer ice ages nearly 1 million years ago.
Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
A schematic overview of the Southern Ocean overturning circulation. The arrows point in the direction of the water movement. The lower cell of the circulation is depicted by the upwelling arrows south of the Antarctic Circumpolar Current (ACC) and the formation of Antarctic Bottom Water beneath the sea ice of Antarctica due to buoyancy loss.
Antarctic sea ice extent peaked this year on Sept. 10, when it covered 16.96 million square kilometers (6.55 million square miles), the lowest winter maximum since satellite records began in 1979 ...
