Lawrence Livermore scientists, working with National Oceanic and Atmospheric Administration and university colleagues, have found that half of the global ocean heat content increase since 1865 has occurred over the past two decades.
NOAA and Raytheon successfully demonstrated several improvements to the Coyote Unmanned Aircraft System (UAS) while completing a mid-flight launch from the NOAA P-3 Hurricane Hunter aircraft on January 7, 2016. The flight verified new technology designed to improve Coyote’s ability to collect vital weather data to improve hurricane forecasts.
Citizen scientists around the world, not just those in the United States, can now submit weather observations and view reports on the go using the newly upgraded mPING smart phone application. Developers from NOAA’s National Severe Storms Laboratory and the University of Oklahoma’s Cooperative Institute for Mesoscale Meteorological Studies announced the app’s expanded reach and utility Monday during the American Meteorological Society’s annual meeting in New Orleans.
ANN ARBOR—If they successfully invade Lake Erie, Asian carp could eventually account for about a third of the total weight of fish in the lake and could cause declines in most fish species—including prized sport and commercial fish such as walleye, according to a new computer modeling study by scientists at the University of Michigan, NOAA's Great Environmental Lakes Research Laboratory, other U.S. and Canadian research institutions.
Scientists from NOAA, the U.S. Army Corps of Engineers and Environment Canada have issued a six-month forecast for water levels to be at or above average on Lake Superior, Michigan, Huron, and Erie into spring of 2016. Lake Ontario water levels are expected to remain close to monthly averages. However, the impacts of the anticipated strong El Niño
and other atmospheric anomalies on the forecast are difficult to predict.
A new paper
appearing online in Atmospheric Environment
coauthored by researchers at NOAA’s Earth System Research Laboratory looked at the climate implications of various proposals for future HFC use that are being discussed this week under the United Nations Montreal Protocol, the global agreement that protects the ozone layer.
The 2015 Antarctic ozone hole area was larger and formed later than in recent years, according to scientists from NOAA and NASA.
On Oct. 2, 2015, the ozone hole expanded to its peak of 28.2 million square kilometers (10.9 million square miles), an area larger than the continent of North America. Throughout October, the hole remained large and set many area daily records.
For centuries, cod was the backbone of New England’s fisheries and a key species in the Gulf of Maine ecosystem. Today, cod stocks in the gulf are on the verge of collapse, hovering at 3-4 percent of sustainable levels. Even setting tighter limits on fishing has failed to slow this rapid decline. Now a new
concludes that rapid warming of Gulf of Maine waters— warming in the last decade faster than in 99 percent of the global ocean —has reduced the capacity of cod to rebound from overfishing, leading to collapse.
The United Nations Intergovernmental Panel on Climate Change (IPCC) elected NOAA’s Ko Barrett to serve as one of three vice chairs for the international body. The IPCC was created to review and assess the most recent scientific, technical, and socio-economic information produced worldwide that is relevant to the understanding of climate change.
New NOAA-led research maps the distribution of aragonite saturation state in both surface and subsurface waters of the global ocean and provides further evidence that ocean acidification is happening on a global scale. The study identifies the Arctic and Antarctic oceans, and the upwelling ocean waters off the west coasts of North America, South America and Africa as regions that are especially vulnerable to ocean acidification.
