Hundreds of samples from snow pits and a 21 m snow/firn core were collected to establish the annual/seasonal/monthly depth-accumulation scale, based on stable-isotope records, stratigraphic analyses and meteorological and synoptic data. The fluctuations of water stable-isotope records show well-preserved seasonal variations. The d18O and dD relationships in precipitation, snow pits and the snow/firn core have the same slope to the covariance as that of the global meteoric water line. The origins of precipitation nourishing the Belukha plateau were determined based on clustering analysis of d18O and d-excess records and examination of synoptic atmospheric patterns. Calibration and validation of the developed clusters occurred at event and monthly timescales with about 15% uncertainty. Two distinct moisture sources were shown: oceanic sources with d-excess <12‰, and the Aral-Caspian closed drainage basin sources with d-excess >12‰. Two-thirds of the annual accumulation was from oceanic precipitation, of which more than half had isotopic ratios corresponding to moisture evaporated over the Atlantic Ocean. Precipitation from the Arctic/Pacific Ocean had the lowest deuterium excess, contributing one-tenth to annual accumulation. # #-------------------- # Funding_Agency # Funding_Agency_Name: Kyoto Institute of Humanity and Nature (Japan) # Grant: #--------------------- # Funding_Agency_Name: US Department of Energy # Grant: contract A107 #-------------------- # Site_Information # Site_Name: West Belukha Plateau Snowpit 1 # Location: Europe>Eastern Europe>Russia # Country: Russia # Northernmost_Latitude: 49.8042 # Southernmost_Latitude: 49.8042 # Easternmost_Longitude: 86.5611 # Westernmost_Longitude: 86.5611 # Elevation: 4107 m #------------------ # Data_Collection # Core_Name: BelukhaSnowPit1 # First_Year: 1999 # Last_Year: 2001 # Time_Unit: AD # Core_Length: 2 m # Notes: #------------------ # Chronology # # # #------------------ # Variables # # End Description/Documentation (lines begin with #) # Data lines follow (have no #) # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components (9 components: material, error, units, anomaly, period, archive, detail, method, C or N for Character or Numeric data) # Data line format: tab-delimited text, variable short name as header # # Missing values -999.0 # depth_m Depth(m), , , m, , , , N density Density, , , g/cc, , , , N temp Temperature (C), , , degree C, , , , N notes notes, , , firn stratigraphy (01 - new fine grained snow; 02 - medium graned snow; 03 - coarse graned snow/firn; 04 - 1-2 mm radiation or wind ice crust; 5 - ice lense or ice layers up to 5 mm thick; 6 - regelate snow/firn; 7 - fine-graned snow firn with aeolian particles; 8 - compact white snow/firn; 9 - hoar), , , , N d18OiceVSMOW delta18O ice, , , per mil VSMOW, , , , N d2HiceVSMOW delta2H ice, , , per mil VSMOW, , , , N depth_m density temp notes d18OiceVSMOW d2HiceVSMOW 0.00 0.34 -999.0 01 -14.07 -100.0 0.05 0.34 -0.9 01 -15.03 -113.2 0.10 0.30 -999.0 01 -15.32 -110.5 0.15 0.30 -999.0 01 -15.64 -115.6 0.20 0.34 -999.0 01 -15.49 -115.1 0.25 0.34 -999.0 01 -18.89 -134.5 0.30 0.36 -999.0 01 -18.26 -139.7 0.35 0.36 -999.0 04 -16.71 -127.3 0.40 0.38 -999.0 04 -15.57 -113.0 0.45 0.38 -999.0 02 -14.93 -102.1 0.50 0.38 -3.3 02 -14.86 -103.4 0.55 0.38 -999.0 02 -14.26 -100.8 0.60 0.37 -999.0 02 -13.68 -93.7 0.65 0.37 -999.0 02 -14.61 -105.6 0.70 0.38 -999.0 02 -13.07 -95.3 0.75 0.38 -999.0 02 -12.42 -91.7 0.80 0.40 -999.0 02;06 -9.13 -59.9 0.85 0.40 -999.0 02 -9.38 -63.1 0.90 0.44 -999.0 05;09 -8.77 -66.4 0.95 0.44 -999.0 05;09 -9.98 -67.9 1.00 0.42 -4.0 05;09 -12.34 -92.5 1.05 0.42 -999.0 02;05 -11.69 -84.3 1.10 0.44 -999.0 02;05 -13.59 -98.8 1.15 0.44 -999.0 02 -15.37 -115.1 1.20 0.42 -999.0 02 -15.40 -118.4 1.25 0.42 -999.0 02;05 -15.17 -107.6 1.30 0.42 -999.0 02 -10.53 -81.2 1.35 0.42 -999.0 02;05 -12.21 -86.8 1.40 0.46 -999.0 02;05 -19.98 -143.7 1.45 0.46 -999.0 02 -22.70 -163.2 1.50 0.46 -6.5 02;05 -21.73 -149.1 1.55 0.46 -999.0 08 -27.94 -204.5 1.60 0.46 -999.0 08 -27.77 -202.8 1.65 0.45 -999.0 08 -25.34 -192.1 1.70 0.45 -999.0 08 -20.97 -156.2 1.75 0.45 -999.0 08 -19.90 -140.4 1.80 0.45 -7.3 05;07 -14.80 -105.4 1.85 0.45 -999.0 05;07 -11.59 -80.2 1.90 0.45 -999.0 05;07 -10.27 -69.1 1.95 0.45 -999.0 05;07 -11.48 -75.5
