Glacier outlines of Hallstätter Glacier in the Dachstein Massif, Austria, are periodically mapped as part of the respective glacier mass balance monitoring program. Outlines are provided in shapefile format and were mapped based on the available DEMs, historical images, orthophotos or satellite images. Glacier area has decreased from 5.3 km2 in 1856 to 2.4 km2 in 2023. Detailed Information is given in Helfricht (2009), Kara (2020) and Bertolotti et al. (in prep.) and in the associated readme files. New outlines will be added as they become available.
The annual glacier mass balance of Hallstätter Gletscher in Austria is measured since 1.10.2006 with the direct glaciological method in the fixed date system (1.10. to 30. 09. of the following year). The accumulation of snow is measured by determination of the water equivalent in 6 snow pits, the ice ablation is measured with 15 stakes drilled into the ice. Results are the annual net mass balance in kg, the total accumulation and ablation, the glacier area and the portions of the area which are subject to ablation and accumulation, the elevation of the equilibrium line and the specific mass balance in kg/m² (= mm w.e.). The accumulation during the winter is determined by the 1 May. The project is funded by the Federal Government of Upper Austria. The measurements are carried out the Institute for Interdisciplinary Mountain Research of the Austrian Academy of Sciences and the company Blue Sky in Gmunden, Austria.
The annual glacier mass balance of Hallstätter Gletscher in Austria is measured since 2006-10-01 with the direct glaciological method in the fixed date system (1st October to 30th September of the following year).

Annual and winter glacier mass balance maps (fixed date system) for Hallstätter Glacier in the Dachstein Massif, Austria, is provided in shapefile format. The shapes contain contour lines delineating areas of equal mass balance as well as elevation zones. Spatially integrated mass balance is derived from point measurements at snow pits and ablation stakes by interpolating between measurement points and extrapolating to unmeasured regions of the glacier. Detailed Information is given in Helfricht (2009) and Bertolotti et al. (in prep.) and in the associated readme files. New data will be added each year. This is complementary information to the data provided by Fischer et al., 2016.

Climate change-driven deglaciation and erosion in high-latitude regions enhance the flux of terrigenous material to the coastal ocean. Newly exposed land surfaces left behind by retreating glaciers are covered by glacial till, which is rich in fine-grained minerals. Many of these minerals are undersaturated in seawater and thus prone to dissolution (i.e., seafloor weathering). Consequently, intensified erosion and mineral weathering may act as an additional CO₂ sink while supplying alkalinity to coastal waters. To evaluate this hypothesis, we carried out a sediment geochemical study in the southwestern Baltic Sea, where coastal erosion of glacial till is the dominant source of terrigenous material to offshore depocenters. We analyzed glacial till from coastal cliffs, sediments, and pore waters for major element composition using inductively coupled plasma optical emission spectroscopy and an elemental analyzer. Water samples were further analyzed for dissolved redox species and dissolved silica by photometry and ion chromatography. These data were then used to quantify mineral dissolution and precipitation processes and to assess their net effect on inorganic carbon cycling.
