NASA Launches Satellite To Monitor Oceans

On Friday, NASA launched the Ocean Surface Topography Mission/Jason 2 satellite into orbit to begin a detailed study of ocean currents, sea-surface height, and surface topology. Scientists hope to use the data gathered by Jason 2 in order to better understand weather patterns and global warming. Further details about the mission objectives (PDF) are also available. Quoting NASA's press release: "Combining ocean current and heat storage data is key to understanding global climate variations. OSTM/Jason 2's expected lifetime of at least three years will extend into the next decade the continuous record of these data started in 1992 by NASA and the French space agency Centre National d'Etudes Spatiales, or CNES, with the TOPEX/Poseidon mission. The data collection was continued by the two agencies on Jason 1 in 2001. Compared with Jason 1 measurements, OSTM/Jason 2 will have substantially increased accuracy and provide data to within 25 kilometers (15 miles) of coastlines, nearly 50 percent closer to shore than in the past."

    Ok I'm really not trolling here and I'm sure I'm exposing my vast ignorance on this topic, but does this seem incredibly underwhelming to anyone else?

      Not underwhelming in the slightest. It just shows you how very little we understand about the Earth, how little we understand about weather, and also ocean currents. One day this information WILL save many, many lives. It's much more valuable than a whole multitude of other projects.

      Agreed, but there's a greater irony. While travel and research above and beyond earth has done wonders to increase our understanding of our own world, what's left undiscovered and unstudied is what lies beneath our oceans. Studying ocean currents and topology is literally superficial in that regard.

    First the government wants to monitor citizens, and now it wants to monitor the oceans? Come on people, I know most of you don't care because you're not an ocean, but what happens when they start going after the other bodies of water? What about other liquids? Other states of matter? This is just the tip of the iceberg, people.

    Oh sure, maybe you think it's fine because the oceans aren't U.S. citizens, but I say constitutional rights should apply to all of Earth's features, and the government should keep its nose out of aquatic affairs. Just because some oceans border terrorist states (through no fault of their own), that doesn't mean all oceans can just be spied on whenever we feel like it.

    Maybe you think this is okay because some oceans have committed terrorist acts like hurricanes and tsunamis, but it would be bigoted of us to condemn all oceans for the actions of a few.

    This has gotten out of hand and needs to stop. Get involved, people!

    ...this is interesting, to say the least.

    The topic of "rogue waves" has gotten much more interest in the past few years. They have been determined to be both larger and more prevalent than thought before. Perhaps Jason will complement the data from the EU mission to help with statistics, and maybe even predictions...

    One can hope. :)

    One statistical outlier doesn't make a trend. One cold winter doesn't undo decades of warmer than average years.

    And taking you at face value on the Antarctic gaining mass, if you think through the implications it is completely consistent with a warming planet. The Antarctic is still very very cold, and warming means an increase in humidity and precipitation, i.e. a larger ice sheet building over the central regions of the continent. That region still hasn't warmed sufficiently to cause large-scale melting.

    Ice sheets are complicated things. Warming in general causes increased melting at the edges (near the lower lattitudes) and increased precipitation over the center. It's just a question of how fast it's adding mass at the center vs. losing it at the sides, but ultimately as it gets warmer the whole thing will melt at some temperature.

    Beside hopelessly confusing weather and climate, you have also been mislead about the UN. The IPCC reports are here, you can talk directly to some of the scientists who contributed to the report here. An attribution graph showing the contributions of man to both warming (GHG) and cooling (mainly sulphates) can be found in the IPCC's 2007 SPM or you could have a look at this one.

    Now please realise that the IPCC does not come up with new science, it is a UN body that gathers scientists from every national science body on the planet and reviews published scientific papers. They do not have ONE report they have ~20yrs worth of reports.

    Assuming you are not just a rabid anti-science troll can you please post some evidence for your claims such as...

    ALL greenhouse gas "global warming" theories require the upper atmosphere to warm proportionally to the surface temperature....the greenhouse warming models allow for local, temporary variations, but NOT for a record cold hemisphere...the UN has retracted their famous, hysterical report about greenhouse warming...Some of the very scientists who were quoted in that IPCC report tried to get their names removed

    Note: I work on the same basis as the IPCC, ie: I only accept evidence that is backed by peer-reviewed publications.
