Editing Rubber duck (section)

===Glacial melting===

In August 2008, [[NASA]]'S [[Jet Propulsion Laboratory]] undertook studies of [[Greenland]]'s [[Jacobshavn Glacier|Jacobshavn Isbræ]] to determine how interior glacial meltflow during the summer influenced its movement. A sophisticated football-sized probe that had a GPS device, pressure sensor, thermometer and accelerometer was lowered by rope into one of the glacier's [[moulin (geomorphology)|moulins]]. The probe's equipment was designed to find structures such as waterfalls inside the ice. Unfortunately the probe went silent, so ninety rubber ducks marked in English, Danish, and Inuit with the text "science experiment" and "reward", along with an email address to contact if found, were also put into the moulins and it was hoped that the ducks would eventually exit and be found by hunters or fishermen around [[Baffin Bay]].<ref>{{cite news |url=https://www.reuters.com/article/us-climate-glacier-idUSN1746514020080921?feedType=RSS&feedName=environmentNews&pageNumber=1&virtualBrandChannel=0|title=Can rubber ducks help track a melting glacier? |access-date=9 December 2016|last=Zabarenko|first=Deborah|date=1 September 2008|publisher=[[Reuters]]}}</ref><ref>{{cite news |url=http://www.nbcnews.com/id/26857674/ns/us_news-environment/t/rubber-duckies-rescue-glacier-research/|archive-url=https://web.archive.org/web/20140310135419/http://www.nbcnews.com/id/26857674/ns/us_news-environment/t/rubber-duckies-rescue-glacier-research/|url-status=dead|archive-date=10 March 2014|title=Rubber duckies to the rescue in glacial research |access-date=9 December 2016|last=Klotz|first=Irene|date=13 July 2010|publisher=[[NBC News]]}}</ref> As of 2012, none of the ducks were found or returned, possibly due to being trapped in large aquifers later discovered inside the ice.<ref>{{cite news |url=http://www.latimes.com/science/sciencenow/la-sci-sn-catastrophic-greenland-melt-20150112-story.html|title=Ice researchers capture catastrophic Greenland melt |access-date=9 December 2016|last=Mohan|first=Geoffrey|date=12 January 2015|work=[[Los Angeles Times]]}}</ref>
