A complete meteorological dataset and data from surface snow samples, snow pits, firn cores and weekly accumulation measurements from a stake array are available. We first investigated the attenuation of the seasonal ?18O signal due to water-vapour diffusion in the snowpack. A comparison of surface snow samples and firn cores of different ages shows that only onethird of the seasonal ?18O signal of the surface snow samples remains in the cores after the first year. No further significant change in the amplitude of the seasonal ?18O signal is found later. Changes in the seasonal distribution of accumulation can lead to a bias in ice-core properties. This is studied on a short time-scale, using high-time-resolution data of accumulation, stable-isotope ratios and air temperature. Mean annual ?18O values from firn cores are not well correlated to annual mean air temperatures. However, the correlation is improved considerably by calculating an annual mean air temperature using monthly mean temperatures weighted by monthly accumulation. At Neumayer, it is mainly the cyclonic activity in late winter/early spring that determines whether and how the core data are biased. #--------------------------------------- # Publication # Authors: Schlosser, Elisabeth; Oerter, Hans # Published_Date_or_Year: 2002 # Published_Title: Annual mean values of d18O, deuterium, and tritium of ice core NM01C82_04. # Journal_Name: # Volume: # Edition: # Issue: # Pages: # Report Number: # DOI: 10.1594/PANGAEA.690380 # Online_Resource: # Full_Citation: # Abstract: #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Alfred Wegener Institute for Polar and Marine Research # Grant: #--------------------------------------- # Site Information # Site_Name: DML Georg-von-Neumayer Station (Fahrzeughalle) # Location: Antarctica # Country: # Northernmost_Latitude: -70.6167 # Southernmost_Latitude: -70.6167 # Easternmost_Longitude: -8.3667 # Westernmost_Longitude: -8.3667 # Elevation: 28 #--------------------------------------- # Data_Collection # Collection_Name: B04 accum Schlosser2002 # First_Year: 1892 # Last_Year: 1981 # Time_Unit: AD # Core_Length: 51.7 # Notes: B04 (NM01C82_04) #--------------------------------------- # Chronology_Information # Chronology: # # Ant2k volcanic event peak date (CE) Depth of volcanic peak in cores (m) # #--------------------------------------- # Variables # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## year age,,,years CE,,ice core,,,N,d180 layer counting, tritium content, dielectric profiling ## accum accumulation rate,snow,,kg/m2/yr,,ice core,,,N,density and depth interval, thinning function applied #------------------------ # Data # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Value: NaN year accum 1981 264 1980 441 1979 572 1978 409 1977 200 1976 285 1975 257 1974 354 1973 198 1972 179 1971 262 1970 172 1969 469 1968 445 1967 322 1966 256 1965 303 1964 295 1963 371 1962 375 1961 382 1960 299 1959 390 1958 353 1957 265 1956 228 1955 442 1954 283 1953 285 1952 339 1951 417 1950 401 1949 295 1948 279 1947 376 1946 504 1945 428 1944 426 1943 422 1942 194 1941 389 1940 260 1939 343 1938 477 1937 314 1936 382 1935 285 1934 322 1933 255 1932 361 1931 382 1930 456 1929 315 1928 362 1927 375 1926 197 1925 323 1924 306 1923 269 1922 216 1921 235 1920 469 1919 434 1918 435 1917 546 1916 328 1915 360 1914 410 1913 410 1912 312 1911 312 1910 299 1909 499 1908 229 1907 414 1906 344 1905 416 1904 489 1903 432 1902 549 1901 304 1900 377 1899 537 1898 364 1897 452 1896 409 1895 263 1894 351 1893 308 1892 323
