The Antarctic ozone hole, which forms annually in the August to October period, reached its peak size on September 11, stretching to 9.3 million square miles (24.1 million square kilometers), roughly the same size as last year’s peak of 9.3 million square miles (24 million square kilometers) on September 16, 2013. This is an area similar in size to North America.
NOAA Sea Grant announced today grants totaling $15.9 million to support over 300 projects around the nation that help build resilient coastal communities and economies. Through university, state and other partnerships, Sea Grant Programs will supplement the federal funding with an additional $7.9 million in non-federal matching funds, bringing the total investment to more than $23.8 million.
Gregory C. Johnson, a NOAA oceanographer at the Pacific Marine Environmental Lab, and John M. Lyman, an oceanographer at NOAA’s cooperative institute with the University of Hawaii, the Joint Institute for Marine and Atmospheric Research, have written an essay published online in Nature Climate Change about how a new international program can help fill a major gap in information about the heat in the deep ocean. We caught up with Johnson to learn more.
NOAA researchers set out this week on a two-week mission to fly over the Arctic to measure how much the ice has melted over the summer and gauge the speed of this fall’s refreezing of sea ice. This is the second year in a row scientists have flown above Arctic waters. Data gathered from both years is testing a hypothesis that increased summer heat stored in the newly sea-ice free areas of the Arctic Ocean lead to surface heat fluxes in autumn that are large enough to have impacts on atmospheric temperature, humidity, wind and cloud distributions.
Last September’s widespread flooding in northeast Colorado, which saw just over 17 inches of rain in one week in the city of Boulder, was not made more likely or more intense by the effects of human-induced climate change, according to a new NOAA-led study published today in the Bulletin of the American Meteorological Society.
A global report released this week on changing carbon dioxide levels in Earth’s atmosphere, oceans, and land environment draws heavily from data and observations by NOAA research scientists and their partners. For the first time, the annual assessment by the Global Carbon Project uses data obtained from autonomous instruments installed by NOAA scientists on its ships and other ships of opportunity and moorings to determine the variability of carbon dioxide in the surface ocean.
Deborah H. Lee, the chief of water management for the U.S. Army Corps of Engineers’ Great Lakes and Ohio River Division, has been named the new director of NOAA’s Great Lakes Environmental Research Laboratory (GLERL). Lee is slated to begin on December 1, 2014.
Nearly 30 years after the protections of the Montreal Protocol were put into place, there’s more evidence that the international agreement to protect Earth’s ozone layer is working, according to a new scientific report released today at the United Nations headquarters in New York.
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.
