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.
On Wednesday, March 14, two NOAA scientists will take questions over Twitter about ice cover on the Great Lakes over the past few months and on the long-term trends.
NOAA’s Great Lakes Environmental Research Lab has monitored ice cover on the lakes for decades. Its measurements have documented wide variations from winter to winter and made possible discoveries about climate links to variation in ice cover.
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.
