BREAKING ICE SKY AND SPACE Weekend Wrap Up October 2, 2016
Weekend WRAP UP October 2, 2016
Back in August 2016 on the Antarctic Peninsula, scientist saw something interesting via natural color satellite imagery, a rift along Larsen C – the continents fourth largest ice shelf has grown significantly larger. The rift is visible in these images acquired on August 22, 2016, with the Multi-angle Imaging SpectroRadiometer (MISR) on NASA’s Terra satellite.

HUBBLE SEES A BREAK UP
the Hubble Space Telescope captured a comet named 332P/Ikeya-Murakami (aka Comet 332P)as it began to disintegrate as it approached the sun. Hubble captured the break-up that took place some 67 million miles (100 million km) from Earth, slightly beyond the orbit of Mars over three-day span in January 2016.
ARCTIC SEA ICE LOWS
NASA: Since satellites began monitoring sea ice in 1978, researchers have observed a steep decline in the average extent of Arctic sea ice for every month of the year …
The sea ice cover of the Arctic Ocean and surrounding seas helps regulate the planet’s temperature, influences the circulation of the atmosphere and ocean, and impacts Arctic communities and ecosystems. Arctic sea ice shrinks every year during the spring and summer until it reaches its minimum yearly extent. Sea ice regrows during the frigid fall and winter months, when the sun is below the horizon in the Arctic.
This summer, the melt of Arctic sea ice surprised scientists by changing pace several times. The melt season began with a record low yearly maximum extent in March and a rapid ice loss through May. But in June and July, low atmospheric pressures and cloudy skies slowed down the melt. Then, after two large storms went across the Arctic basin in August, sea ice melt picked up speed through early September.
