Icebergs detected from space

CLS provides the Vendée Globe 2016 its knowledge in processing satellite data and radar imagery, altimetric/elevation datas (sea level), and ocean currents models to detect icebergs and forecast ice drift throughout southern latitudes.

Why use satellite detection ?

Satellites are the only way to monitor large and dangerous areas around the Austral ocean. Moreover, radar satellites provide relevant images despite cloud-cover or night.

Which satellite is used for ice detection ?

For ice detection, engineers form CLS use altimetry satellites like Saral or Jason-3, developed by CNES, as welle as  radar images from  RADARSAT-2 satellite developed by the Canadian spatial Agency and SENTINEL-1 developped by the European spatial Agency (ESA).

What do the skippers and the race organizers receive from CLS?

CLS software detects icebergs automatically, but an analyst intervenes to validate all detected icebergs. The analysts also identify “high density zones” — where icebergs are likely to be present. CLS sends regular bulletins to the race organizers in order to signal the presence of icebergs and forecast drift. This information is used to update the Antarctic Exclusion Zone.  The race organizers then send all important information on to the skippers.
