Holocene History of a Portion of Northernmost Ellesmere Island
Radiocarbon dates and glaciological features of the Ward Hunt area along northernmost Ellesmere Island suggest the following chronology, which is consistent with worldwide climatic oscillations: 1) 10,000-4100 B.P.: deglaciation, and development of several marine levels, particularly one now 40 m above sea level, at 7500 ± 300 B.P.; 2) 4100-2400 years B.P.: climatic deterioration, glacial readvance and formation of ice shelves; 3) 2400-1400 years…
Smithsonian Institution Radiocarbon Measurements VIII
This list includes samples completed to July, 1972. All samples are counted for at least 2500 min., and X 2 analyses are made on 100-min. print-outs. Errors quoted are 1 σ , derived from sample, background, and NBS oxalic acid standard measurements, adjusted where appropriate for small-sample dilution
Smithsonian Institution Radiocarbon Measurements VII
This list includes those samples dated between December 1968 and July 1971. Samples before SI-617 were completed before the laboratory was dismantled in April 1969 for renovations in the Smithsonian Institution Building. Samples beginning with SI-617 were dated after December 1970, following re-establishment of the laboratory in new quarters
Smithsonian Institution Radiocarbon Measurements VI
This list includes those analyses completed December, 1968, with equipment and procedures previously employed here
Smithsonian Institution Radiocarbon Measurements V
Included in this list are analyses made during 1967 and the first half of 1968 with equipment and techniques previously employed here. All methane was produced in the bomb reactor
Smithsonian Institution Radiocarbon Measurements IV
Most of these analyses we obtained during 1966 with equipment and techniques previously employed. Methane from the higher numbered samples was produced in a bomb reactor at pressures up to 1000 psi. Also, many smaller samples were counted in a 700-ml vol counter at 2 atm pressure, which has a background of 1.76 = .02 counts/min
Smithsonian Institution Radiocarbon Meaurements III
Most of these analyses were performed during 1965 with equipment and techniques previously employed at this laboratory. A cold (−40°C) charcoal trap stage was added to the CO 2 purification to remove radon, which eliminates the lag time between CH 4 preparation and counting (Long, 1965b)
