The article discusses the changes of Mittivakkat Gletscher glacier in Greenland with observation that it have thinned and receded throughout the past several decades. It documents changes with surface velocity measurements and long-term mass balance observations. It is noted that the glacier shrank by 18 percent in surface area, 20 percent in mean ice thickness, and 33 percent in volume between 1986 and 2011.

    We present detailed records of lake discharge, ice motion and passive seismicity capturing the behaviour and processes preceding, during and following the rapid drainage of a ~4 km2 supraglacial lake through 1.1-km-thick ice on the western margin of the Greenland Ice Sheet. Peak discharge of...

    We used a terrestrial radar interferometer (TRI) at Helheim Glacier, Greenland, in August 2013, to study the effects of tidal forcing on the terminal zone of this tidewater glacier. During our study period, the glacier velocity was up to 25md-1. Our measurements show that the glacier moves out...

    The article focuses on glacier dynamics at Helheim, Kangerdlugssuaq and other 14 major Greenland glaciers period of the 20th century. It says that the Greenland ice sheet is experiencing an increase rates of mass loss due to changes from tide water glaciers. It states that in 1995-2010, there...
