Scientists used satellite imagery and data to analyze vegetation levels on the Antarctic Peninsula, a long mountain chain that points north to the tip of South America, and which has been warming ...
The need for satellite imagery from geostationary and polar-orbiting satellites over the Antarctic led to the formation of the AMRC. Today, the AMRC continues to create Antarctic satellite composites and conduct research with those composites and other observational data sets, such as those from UW-Madison’s AWS program.
This is a list of satellite map images with missing or unclear data. Some locations on free, publicly viewable satellite map services have such issues due to having been intentionally digitally obscured or blurred for various reasons of this. [ 1 ]
A23a's course mapped by the NASA Earth Observatory [1]. 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.

The 20-foot-long Ran submersible used pulsed sound waves (advanced multibeam sonar) on the ice to map its features, but because of its subantarctic location, Wåhlin and her team couldn’t ...
The satellite images have pixel ground resolutions of under 0.5 meters, and overlapping images from different angles can be used to extract elevation data for DEMs. Based only on satellite position, there may be errors of several meters, but through ground control registration these can be reduced to point-to-point errors of 20 centimeters or ...
Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet.. Vostok is located near the southern pole of inaccessibility and the south geomagnetic pole, making it one of the optimal places to observe changes in the Earth's magnetosphere.
