30 paź 2024 · The sea ice cover is one of the key components of the polar climate system. It has been a focus of attention in recent years, largely because of a strong decrease in the Arctic sea ice cover and modeling results that indicate that global warming is amplified in the Arctic on account of ice-albedo feedback.

A satellite composite image of Antarctica. Earth's south polar land mass, Antarctica, is covered by the Antarctic ice sheet. It covers an area of about 14.6 million km 2 and contains between 25 and 30 million km 3 of ice. Around 70% of the fresh water on Earth is contained in this ice sheet.
The southern polar cap has a diameter of 350 km and a thickness of 3 km. [7] The total volume of ice in the south polar cap plus the adjacent layered deposits has also been estimated at 1.6 million cubic km. [8] Both polar caps show spiral troughs, which recent analysis of SHARAD ice penetrating radar has shown are a result of roughly ...
The satellite has an ice-penetrating radar called MARSIS, which can see through Mars’ southern ice cap. It revealed an area at the base of the ice that strongly reflected the radar signal, which was interpreted as an area of liquid water beneath the ice cap.
2 mar 2023 · Today's VIS image shows part of the south polar cap. This image was taken near the end of southern summer. The cap was created over millions of years with deposition of ice and dust during different seasons, creating layers.
19 paź 2023 · On Mars, the polar ice caps are called the Planum Australe (southern) and the Planum Boreum (northern). The martian ice caps are made of water and carbon dioxide about thre kilometers (1.9 miles) thick.
