NOAA flies over Arctic to measure extent of sea ice

Annual fall mission helps gauge climate change in Arctic

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. 

NOAA launches research on next generation of high performance weather, climate models

NOAA collaborates with U.S. Navy, other public and private partners to create faster, lower-cost models

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.

A more acidic Arctic? NOAA deploys first buoy in region to monitor levels of CO2 absorbed by ocean

NOAA’s Pacific Marine Environmental Laboratory in partnership with the Marine Research Institute in Iceland deployed the first high-latitude ocean acidification monitoring buoy in the Atlantic Ocean in early August.  The moored buoy is the first of its kind to be deployed north of the Arctic circle in a region where very little is known about how carbon dioxide (CO2) is entering the ocean environment. 

Like butter: Study explains surprising acceleration of Greenland’s inland ice

Surface meltwater draining through cracks in an ice sheet can warm the sheet from the inside, softening the ice and letting it flow faster, according to a new study. During the last decade, researchers have captured compelling evidence of accelerating ice flow at terminal regions, or “snouts,” of Greenland glaciers as they flow into the ocean along the western coast.

Climate models project that combinations of heat and humidity could reach deadly thresholds for anyone spending several hours outdoors by the end of the 21st century. However, new NOAA-supported research says these extremes are already happening — decades before anticipated — due to global warming to date.

New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch.
