Earth’s chilly bottom
The chilly bottom of satellite Earth , the southernmost continent and a position that boasts nothing but extreme , is a winter wonderland for a trove of rum scientist . In the large airborne survey to date of the Pole , NASA ’s IceBridge task is aimed at read the speedily alter ice of both Antarctica and Greenland . Once a yr , from March to May over Greenland and October November over Antarctica , enquiry aircraft flee above the ice sheets to look for grounds of change . Besides collecting priceless climate - related datum , the surveys have also delivered jaw - drop images of the vast expanses of crank . Here ’s a look at the gorgeous photos snapped of Antarctica during a Nov. 3 , 2017 , escape aboard a retrofitted 1966 Lockheed P-3 aircraft over Antarctica .
Sea ice and glaciers
The November flight took researchers above sea glass in Western Antarctica , including the Bellingshausen and Weddell seas and glaciers in the Antarctic Peninsula and along the English and Bryan Coasts .
Rising sea levels
Researchers using IceBridge data have found that the West Antarctic Ice Sheet may be in a state of irreversible decline , something that could forthwith contribute to rising ocean levels .
Green laser pulses
The main instrument aboard the P-3 was a optical maser altimeter , which appraise the height of the ice surface , concord to NASA . The scientists used a greenish optical maser and a twofold - people of colour one to transmit both infrared and dark-green laser pulses .
Antarctic measurements
Onboard radar sounder measured thickness and layering of the snow and ice ; a eminent - firmness television camera captured images of the terrain ; and an infrared camera to quantify open temperature .
Magnetic measurements
The plane also carries a gravimeter and gaussmeter to record tiny pas seul in Earth ’s gravity and magnetic field , severally , according to NASA ’s Earth Observatory . The magnetic properties of the bedrock beneath the float meth shelf and glacier tell scientist what eccentric of stone is present there .
Feeling the heat
The most uninhabited landmass is feel the heat of climate change …
Amazing Antarctica
The National Climate Assessment , a study produced every four long time by scientists from 13 Union politics agency , released a arrant report Nov. 2 , 2017 , state that the world-wide temperature rise over the past 115 old age has been primarily have by " human activities , specially emissions of greenhouse gases . "
Artistic views
Sea - ice floes in Antarctica create fascinating pattern and hue when see from above .
Polar window
A sentiment from a windowpane in the research craft gives scientists a view of the expansive continent .
Icy desert
Though Antarctica is covered in snow and ice and the coldest stead on Earth , it is actually a desert : It seldom rain or snowfall . The snow that does fall does n’t melt and rather builds up into thick crank sheet .
