  1. 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.

    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.

  7. A ground station for Jason-2

    Date de publication:

    26 Septembre 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. 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.

  9. Jason-2: watching sea level and weather

    Date de publication:

    30 Avril 2004

    Satellites monitor sea level, wave height, wind speed and current movements from space. Like its predecessors, Jason-2 will obtain all these data from altimeter range measurements.

  10. Jason-2: a family affair

    Date de publication:

    27 Mai 2008

    Jason-2’s main mission is to take over from its predecessor Jason-1 and assure data continuity. But the latest in the series of oceanography satellites is also carrying some new passengers. A brief tour of the “added extras” on Jason-2...

  11. A leap forward for oceanography

    Date de publication:

    10 Juin 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.

  12. Charting and forecasting ocean conditions

    Date de publication:

    3 Juin 2008

    Satellite altimetry is the only space-based technology capable of penetrating below the ocean surface. This capability will benefit a broad range of ocean forecasting applications, now and in the future.

  13. Jason-2 all set for the off

    Date de publication:

    18 Juin 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.
