NOAA flies over Arctic to measure extent of sea ice

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.

Climate models show carbon emission mitigation could slow Arctic...

NOAA-led research using climate model projections concludes the Arctic climate will continue to show major changes over the next decades, but that carbon emission mitigation could slow temperature changes in the second half of the century, according to a paper published by AGU’s Earth’s Future.

A more acidic Arctic? NOAA deploys first buoy in region to monitor...

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...

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.

Before satellites, weather data transmitters, or computers, there were the ship's logs of Arctic sea voyages. A new crowdsourcing effort could make the weather data from these ship logs available to climate scientists worldwide.
