Radiocarbon Reservoir Ages in the Holocene Dead Sea
The sources and fate of radiocarbon ( 14 C) in the Dead Sea hypersaline solution are evaluated with 14 C measurements in organic debris and primary aragonite collected from exposures of the Holocene Ze’elim Formation. The reservoir age (RA) is defined as the difference between the radiocarbon age of the aragonite at time of its precipitation (representing lakeʼs dissolved inorganic carbon [DIC]) and the age of contemporaneous organic debris (repr…

Sea level implications from Late Quaternary/Holocene paleosols from the Oujiang Delta, China
We describe two coastal paleosols recovered in sediment cores from the Oujiang Delta, Southeast China. These provide useful benchmarks for past sea level change on the East China Sea coast. Radiocarbon ( 14 C) dates on charcoal and plant matter show that one formed during Marine Isotope Stage 3 (MIS 3) and was exposed for perhaps 20 ka, during the Last Glacial Maximum. The other formed in the Early Holocene and was briefly exposed, during a perio…
Preliminary Investigation on the Rapid and Direct AMS Measurement of 129 I in Environmental Samples without Chemical Separation
Accelerator mass spectrometry (AMS) is the most sensitive method for measuring 129 I in environmental samples available today, with a detection limit of about 10 –15 for 129 I/ 127 I. A drawback of the technique is the time-consuming chemical separation required to prepare AMS targets from raw samples. This step significantly limits applications requiring rapid analyses and large numbers of samples, for example, in monitoring studies associated w…

Regional Radiocarbon Effect Due to Thawing of Frozen Earth
Accelerator mass spectrometry (AMS) measurement of 25 single-year tree rings from AD 1861–1885 at ca. ±3.5‰ precision shows no evidence of an anomalous 11-yr cycle of 14 C near the Arctic Circle in the Mackenzie River area. However, the Δ 14 C measurements are lower on average by 2.7 ± 0.9 (ō)‰ relative to 14 C measurements on tree rings from the Pacific Northwest (Stuiver and Braziunas 1993). We attribute this depression of Δ 14 C to thawing of …

Anomalous 11-Year Δ 14 C Cycle at High Latitudes
We find no evidence for an anomalously intense 11-yr cycle in Δ 14 C at high latitudes during the period, AD 1870–1885, as reported by Fan et al . (1983, 1986). However, there does appear to be a regional effect within the MacKenzie River region (67°N, 130°W), with atmospheric 14 C depressed by relative to the Olympic Peninsula. Such an effect would require only 5% of CO 2 in the air mass to have been derived from 5% 14 C-depleted soil gas CO 2 .…
