An analysis of the carbon balance of the Arctic Basin from 1997 to 2006
This study used several model-based tools to analyse the dynamics of the Arctic Basin between 1997 and 2006 as a linked system of land-ocean-atmosphere C exchange. The analysis estimates that terrestrial areas of the Arctic Basin lost 62.9 Tg C yr−1 and that the Arctic Ocean gained 94.1 Tg C yr−1. Arctic lands and oceans were a net CO2 sink of 108.9 Tg C yr−1, which is within the range of uncer...
متن کاملElevation change , mass balance , dynamics and surging of Langjökull , Iceland from 1997 to 2007
Glaciers and ice caps around the world are changing quickly, with surge-type behaviour superimposed upon climatic forcing. Here, we study Iceland’s second largest ice cap, Langjökull, which has both surgeand non-surge-type outlets. By differencing elevation change with surface mass balance, we estimate the contribution of ice dynamics to elevation change. We use DEMs, in situ stake measurements...
متن کاملGattaca (1997)
Gattaca is a 1997 science fiction film produced in the US that depicts a future society that uses reproductive technology [5] and genetic engineering in order to produce genetically enhanced human beings. By selectively choosing certain genes [6], scientists and physicians ensure that individuals born using reproductive technologies have desirable physical and psychological traits and prevent u...
