Аннотация:The objective of the stable isotope investigations is to better understand the recent hydrology in the Northeast Siberian Arctic by using stable water isotopes. The research comprises
continuous sampling of precipitation and snow, ice, rivers, lakes, ponds on various
timescales (from event-basis to annually repeated samplings). This years’ focus will be
the transformation of snow in spring due to precipitation events, evaporation/sublimation,
snow melt and runoff. Therefore, the fieldwork included a detailed and repeated sampling
of snow profiles to monitor the spatial and temporal changes in its snow characteristics as
well as its isotope geochemical composition on Samoylov Island.
