1. Firn Accumulation Processes in Taylor Dome, Vostok and Siple Dome Ice Using Cosmogenic 14 C and 10Be as Tracers [lal_9909484]
This award is for support to develop a history of snow accumulation and physical processes occurring in the upper layers of ice deposited at several sites in Antarctica, using cosmogenic ...


2. Physical and chemical oceanic parameters available from NOAA's Ocean Atmosphere Carbon Dioxide Exchange Study (OACES) [NOAA_AOML_OACES]
NOAA's Ocean Atmosphere Carbon Dioxide Exchange Study (OACES) seeks to enhance our understanding of the role of the ocean in sequestering the increasing burden of anthropogenically-derived ...


3. Firn Air Study in the Megadunes Near Vostok, Antarctica [severinghaus_nsf0230452]
This award supports a study of the chemical composition of air in the snow layer (firn) in a region of "megadunes" near Vostok station, Antarctica. It will test the hypothesis that a deep ...


4. Alaska Radiocarbon Data Base; USGS, Menlo Park [USGS_ALASKA_RADIOCARBON]
This data base contains published radiocarbon dates with entries consisting of laboratory and reference numbers. The data set is subdivided into two segments including RCFILE which contains the radiocarbon ...


5. Causes of Climate Change Over the Past 1000 Years, NOAA/NCDC/WDC Paleoclimatology [NOAA_NCDC_PALEO_2000-045]
Recent reconstructions of northern hemisphere temperatures and climate forcing over the last 1000 years allow the warming of the 20th century to be placed within a historical context and various mechanisms ...


6. Reconstructed Solar Irradiance Data, 1200 Years [NOAA_NCDC_PALEO_2003-006]
Data set consists of reconstructed solar irradiance data and cosmogenic nuclide production (10Be and 14C) from an ice core at the South Pole (Raisbeck 1990). Based on a quantitative study of the ...


7. IPCC Working Group 1, 1994: Modelling Results Relating Future Atmospheric CO2 Concentrations to Industrial Emissions, CDIAC DB-1009 [CDIAC_DB1009]
This data base contains the results of various projections of the relation between future carbon dioxide (CO2) emissions and future industrial emissions. These projections were contributed by groups ...


8. C-14 Age Measurement of Buried Woods Sampled in Aomori Prefecture [BURIEDWOODS-HIT1994]
The authors present the following 4 remarks as the results of caron-14 measurement in 1989-1993. (1) The sample collected at Januma, Sannohe, coincided with that excavated from Hachinohe tephra. (2) ...


9. C-14 Dating and C-14 Concentration of Environmental Samples in the Area of Aomori Prefecture [ENVIRONMENT-HIT1994]
Technical comments on the chemical processing process and the calculation of ageand concentration of samples, regarding C-14 age determination and C-14concentration measurement, are given and further, ...


10. C-14 Specific Activity of Farm Products and Marine Products Collected from the Rokkasho Area in Aomori Prefecture [FARMMARINEPRO-HIT1994]
We investigated C-14 specific activity of farm products and marine products which were collected from the Rokkasho area in Aomori prefecture from 1988 to 1990. The measured C-14 specific activity ...
