The answer is important for understanding how the Earth system is responding to climate change.
NOAA Ship Ronald H. Brown steamed out of Charleston, South Carolina, on February 15, 2018, for a multi-stage trip around the world to improve ocean data that informs US and global weather prediction.
The Southern Ocean that encircles Antarctica lends a considerable hand in keeping Earth's temperature hospitable by soaking up half of the human-made carbon in the atmosphere and a majority of the planet's excess heat. Yet, the inner workings — and global importance — of this ocean that accounts for 30 percent of the world's ocean area remains relatively unknown to scientists, as observations remain hindered by dangerous seas.
NOAA and the U.S. Navy are teaming up with academic and other government scientists to design the next generation of powerful supercomputer models to predict weather, ocean conditions and regional climate change.
Four teams of scientists are beginning projects this month to rewrite computer models that will create faster, lower-cost, better integrated models. These new models will take advantage of new supercomputers that use more energy efficient/lower-cost processors such as those originally developed for the video gaming industry.
Middle and high school students in six cities across America have won the chance to deploy a NOAA global ocean drifter for Earth Day, earning the opportunity to launch a small 44-pound floating buoy into an ocean current.
Scientists have found a large reduction in the amount of the coldest deep ocean water, called Antarctic Bottom Water, all around the Southern Ocean using data collected from 1980 to 2011.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
