Carbon dating demonstration
The purpose of this trip was to retrieve 4 ice cores (~3 m in length each) transecting the southern half of the ice tongue fed by the southern cirque (Fig. These locations were chosen due to the findings from Holmlund (1998) as well as a visual glacial deformation on the surface of the northern tongue. Analysis using the LA-ICP-MS will be conducted starting in January 2016.The ice cores are now stored in the Ultra Cold Clean Lab for state-of-the-art, sub-annual analysis using the LA-ICP-MS trace element analysis at 121 micrometer resolution in the W. To analyze H and O isotope ratios a longitudinal slice was cut (102.5 cm in total length) from runs 3 & 4 (1.15 and 1.7 m depths, respectively) of Site 2.Project Summary This report is to follow up on a scientific expedition to Mårmaglaciären in the Kebnekaise Range, Sweden (Fig. The aim of the project is to begin searching for viable ice coring locations in northern Sweden for reconstructing atmospheric conditions over northern Scandinavia.

All scientists can do, and all they have done, is test the carbon levels in a few areas of our atmosphere, and everything else is the same.The slice was then cut into 2-cm resolution sections, melted in bottles, and sent to Douglas Introne (Climate Change Institute) for isotope analysis.Preliminary results of ∂2H and ∂18O from the comparison between the snow pit (10-cm resolution) and the ice core section from Site 2 reveal that the isotope record is washed out at the near surface level.If you cannot be omni-present, which would be required for such a feat, then all you can do is put a guess on the number.
