The flow of Pine Island Glacier in Antarctica as seen by Sentinel-1

In English Sentinel-1 snow-ice

Simon Gascoin, 5 novembre 2019

The clip below shows the evolution of Pine Island glacier ice tongue in West Antarctica, from June 2017 to October 2019. I made it with 111 quicklooks of Sentinel-1 radar images processed by the Alaska Satellite Facility and available via the vertex data portal. All images were acquired in interferometric wide swath mode (polarization HH, only ascending passes, path: 65) and projected to ground range.

During this short period, two « Manhattan-sized » icebergs calved off the glacier tongue, and the next one is coming soon!

This area was imaged every 6 days by Sentinel-1A and Sentinel-1B with a constant look angle.

PS. this post is just a throwback of this one about the Thwaites ice shelf:

BIOMASS, the third launched satellite mission designed at CESBIO !

After SMOS in 2009, and VENµS in 2017, the CESBIO laboratory is very proud to see its third proposed mission, Biomass, reach orbit. As always, it has been a long journey from the idea, at the beginning of the century, to the selection in 2013 as the seventh Earth Explorer Mission by ESA, to the […]

Evolution de l’altitude de la ligne de neige au cours des 41 dernières années dans le bassin versant du Vénéon (Oisans)

Pour contribuer à caractériser les conditions hydrométéorologiques lors de la crue torrentielle qui a frappé la Bérarde en juin, j’ai analysé une nouvelle série de cartes d’enneigement qui couvre la période 1984-2024 [1]. Grâce à la profondeur temporelle de cette série, on constate que l’altitude de la ligne de neige dans le bassin versant du […]
