  5. A ground station for Jason-2

    Publishing date:

    September 26, 2006

    The Jason-2 altimetry satellite will take over from Jason-1 in 2008, extending the continuous series of ocean measurements acquired starting in 1992 with Topex/Poseidon. Ground stations for Jason-2 are already being deployed. One of them, at Usingen, Germany, entered service on 28 September.

  8. COP21 space agenda Jason-3 satellite successfully launched

    Publishing date:

    January 17, 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.

  9. Jason-2 all set for the off

    Publishing date:

    June 18, 2008

    The Jason-2 oceanography satellite is now in the home straight and set for launch Friday 20 June. Before reaching final orbit, the satellite will go through a sequence of steps just after launch and during the beginning-of-life phase of its mission. Jason-2 teams are watching launch preparations advance in California with much relief after a series of setbacks over the last 2 weeks. First, successive delays in the launch of the GLAST satellite pushed back the departure of Jason-2, since the same ground teams were preparing both satellites; and then poor weather prevented the satellite from being mated with the launcher as planned.

  15. A leap forward for oceanography

    Publishing date:

    June 10, 2008

    Over the last 15 years, altimetry satellites have been poring over the oceans in every detail, collecting more data in 10 days than could be gathered over several centuries by ships. This nascent revolution in oceanography promises to improve climate forecasting.

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

    Publishing date:

    May 7, 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.
