  1. Jason-1 clocks up 10 years of climate observations

    Date de publication:

    7 Décembre 2011

    The Jason-1 ocean-observing satellite has been in orbit for 10 years. In that time, it has helped to build up a 20-year time series of continuous sea-surface measurements to enhance our understanding of climate change.

  2. Jason-2 takes to the air

    Date de publication:

    7 Mai 2008

    Since 1992, altimetry satellites have significantly enhanced our knowledge of the world’s oceans. The Jason-2 satellite is all set to take over the ocean-observing mission of its predecessors Jason-1 and Topex/Poseidon. It recently arrived at Vandenberg Air Force Base, California, in preparation for launch on 15 June.

  6. COP21 space agenda Jason-3 satellite successfully launched

    Date de publication:

    17 Janvier 2016

    The Jason-3 oceanography satellite was launched Sunday 17 January at 19:42 CET from Vandenberg Air Force Base (VAFB), California, by a Falcon 9 launcher supplied by NASA. The satellite then came under control of teams at the Toulouse Space Centre to switch on the bus and payload. Jason-3 will now begin its mission to extend the long record of high-precision ocean current and sea-surface height data built up by its predecessors TOPEX/Poseidon, Jason-1 and Jason-2.

  10. Sea elephant oceanographers: a 10-year success story

    Date de publication:

    7 Mai 2013

    For the last 10 years, more than 200 elephant seals have been patrolling the southern seas wearing some strange headgear: an Argos transmitter instrumented with temperature, salinity and pressure sensors. The data these sensors acquire are fed in near-real time into the Mercator operational oceanography model and also tell us more about the animals' ecology.
