MARC recordMeasurements of cosmic-ray-produced 14C in firn and ice from Antarctica / A.J.T. Jull, D.J. Donahue, D. Lal, B. Deck.
| Title: | Measurements of cosmic-ray-produced 14C in firn and ice from Antarctica / A.J.T. Jull, D.J. Donahue, D. Lal, B. Deck. |
| Author(s): | Jull, A. J. T. Donahue, D. J. Lal, D. Deck, B. |
| Date: | 1992. |
| In: | Eos : transactions, American Geophysical Union. (1992.), Vol. 73(43, fall meeting supplement) (1992) |
| Abstract: | Abstract only. Reports new measurements from Dome Circe and Newall Glacier, Victoria Land, using improved methods of extraction of in-situ ¹⁴CO and ¹⁴CO₂. Observed concentrations are usually lower than expected for complete retention of ¹⁴C, using accumulation rate assumed for thee sites. In-situ ¹⁴C is retained to extent sufficient to modify ¹⁴C/¹²C ratio expected in ice from trapped CO₂ at or below firn/ice transition zone. |
