Mauritius is best known as a tropical holiday paradise island in the Indian Ocean, but for an Earth Science research team led by Professor Trond H. Torsvik it is piece of a geological puzzle. Now they have found a new fragment of an ancient continental crust beneath the young, but inactive volcanoes on the island.
Cross disciplinary approaches using both seismic recordings and satellite observations of glaciers provide data to estimate glacier frontal ablation rates. This provides new insight into the processes that control dynamic mass loss of glaciers into the sea. Such cross disciplinary approaches can be valuable in climate research.
For 56 mill years ago the climate on Earth changed rapidly and the temperature increased at least 5 degrees. Scientists are now closer to understand the climate change, called PETM, and why it lasted over 150 000 years. The answer might be eruptions of methane gas from craters offshore Norway.
Recently, a Danish-Norwegian research team re-processed thousands of aerial photos into 3D Digital Elevation Models (DEM) surrounding the entire coastline of Greenland. The new data extends the precise geometric record of Greenland glacier margins to the late 1970s and 80s and can be used to quantify the decline in the ice mass, for example. The data is freely available to the public domain.
International team of climate researchers reconstructs global cooling in the reign of the Roman emperor Justinian. Ice-cores and data about sulfate flux at Greenland and Artica reveils the pasts climate disasters. Their research presented at EGU 2016; Vienna recently.
