Abstract:
[Adapted from the NDP-057 documentation] This Numeric Data Package (NDP-057) contains 15 data files from the Radiologic Dating Laboratory at the Norwegian Institute of Technology that provide 1619 estimates of del 14C, del 13C, and DELTA 14C in atmospheric CO2 from 14 locations. spanning latitudes from Spitsbergen (78N) to Madagascar (21S). The period of record differs by station. The earliest measurements were made in 1962, and the latest estimates are from 1993. Most stations have records only for the 1960s. All of the data files have the same format and none contain missing values. Some del 13C values are flagged as mean values; users are urged to pay attention to these flags before analyzing or interpreting the corresponding values. The samples collected were supplemented during 1962 by high altitude air samples collected by the Norwegian Air Force. The resulting database, coupled with other 14C data sets, provides a greater understanding of the dynamic carbon reservoir and a crude picture of anomalous sources and sinks at diffrent geographical latitudes. This database is outstanding for its inclusion of early 14C measurements, broad spatial coverage of sampling, consistency of sampling method and DELATA 14C calculation results corrected for isotopic fractionation and radioactive decay. The DELTA14C values are the uncorrected measurement of excess 14C in atmospheric CO2. DELTA13C represents the deviation in the 13C/12C ratio.
