Roundup: Pollen in Ice Cores, Melting in Greenland, and Water Usage in Switzerland

Pollen found in ice cores

From Arctic, Antarctic, and Alpine Research: “Pollen grains are commonly found in ice cores, particularly those from mountain glaciers at low to middle latitudes … We analyzed major pollen grains in an 87-m-deep ice core drilled at the top of the Grigoriev Ice Cap (4563 m.a.s.l.) in the Tien Shan Mountains, Kyrgyz Republic. Microscopy showed that mainly five pollen taxa were contained in the ice core.”

Glacial meltwater’s influence on biogeochemical cycles in greenland

From Frontiers in Marine Science: “Greenland fjords receive considerable amounts of glacial meltwater discharge from the Greenland Ice Sheet due to present climate warming. This impacts the hydrography, via freshening of the fjord waters, and biological processes due to altered nutrient input and the addition of silts … Our results imply that glacially influenced parts of Greenland’s fjords can be considered as hotspots of carbon export to depth. In a warming climate, this export is likely to be enhanced during glacial melting.”

Water usage in Oberhasli, Switzerland

From Environmental Science and Policy: “Incoherent institutional regimes are among the most critical barriers to adapt water governance under climate change. However, it remains unclear how different governance processes can coordinate competing resource uses despite incoherence of institutional resource regimes. This paper examines how institutional resource regimes and polycentric governance processes are co-evolving and to what extent these processes coordinate competing resource uses in incoherent resource regimes. ”
