Glaciologists have noticed that the rapid shrinkage of their French glacier using newly gathered satellite information.

Cook Ice Cap

Over the past four years, scientists have observed the thinning of the Cook ice cap by roughly 1.5 meters annually. The reduction in the region of the glacier was at roughly 20%. The retreat of the glacier was listed as being twice as fast as 1991. This study on the shrinkage of the ice cap was printed in the Journal of Geophysical Research.

The first research completed on the melting of the Cook ice cap revealed an initial slow escape of this Ampere glacier, which can be among the outlet glaciers of the Cook ice cap between 1800 and 1965, which then became far more rapid.

In situ observation of this French glacier has been completed since 1974. Yet, observations conducted from distance between 1991 and 2006 have enabled scientists to gather information regarding the French glacier that’s situated in a rather inaccessible location.

Glaciologists started their research of this French glacier by simply compiling a comprehensive inventory of those glaciers located on the Kerguelen Islands’ dad cap. At the moment, these glaciers covered over 700 km square, such as the 500 km square occupied by the glacier alone.

From 1991, the glacier inhabited 448 km square, which region had decreased to 403 km square by 2003. In total, the French glacier has dropped 20 percent of its place in 4 years, and continues to be quickly retreating twice as quickly since 1991. In addition, the scientists could gauge the quantity reduction or mass balance of the glacier during the past 4 decades.

This mass stability provides a precise characterization of the reaction of the glacier to climatic version – temperature and precipitation – and could possibly be utilized at the contrasts of glacial responses for a variety of areas of the planet. By way of instance, the Cook ice cap has thinned by up to 300 – 400 meters at glacier tongues at low altitude, whereas the variations in thickness appear smaller at higher areas.
