There are 30 % more sediments on the seabed than previously expected, reveal an update of the map GlobSed. This equates to up to two kilometers of extra land mass over today’s land area.
New data and analysis show that land-based glaciers outside of the main ice sheets in Antarctica and Greenland have lost more than 9,000 billion tons of ice since 1961, raising sea levels by 27 millimeters.
Salt precipitation, which creates trouble when injecting CO2 into porous stone, has the potential to clog leakage pathways in the caprocks.
A new methodology to combine heaps of satellite images allows researchers from University of Oslo with colleagues to create a complete time series of glacier movement. To demonstrate the methodology, they created a map of ice flow every month, over several years, covering several mountain ranges in Southern Alaska and Canada. Once created, the dataset revealed several sudden glacier speed-ups and slow-downs.
