Application of Tandem Accelerator Mass-Spectrometer Dating to Late Pleistocene-Holocene Sediments of the East Antarctic Continental Shelf
Glacial recession from the Antarctic continental shelf is recorded by glacial-marine diamictons, sands, and overlying siliceous oozes. In order to clarify the chronology for this sequence, use was made of the University of Arizona tandem accelerator mass-spectrometer (TAMS) for 14 C dating. Small samples of benthic and planktonic foraminifera were selectively removed from diamictons, graded sands, and surface sediments which were recovered from t…

Spallogenic 14C in High-Altitude Rocks and in Antarctic Meteorites
14 C in high-altitude rocks and in Antarctic meteorites of long terrestrial age has been found at levels consistent with in-situ production by cosmic rays. Levels of 0.2–0.59 dpm/kg (or 1.0–2.6 × 10 6 14 C/g) are found in high-altitude samples ranging from 3300 to 5460m. Similar values are observed in Antarctic meteorites that have been dated by 81 Kr by Freundel, Schultz & Reedy (1986) as over 100 kyr old
Radiocarbon in Dissolved Organic and Inorganic Carbon From the Central North Pacific
Radiocarbon measurements are reported for dissolved organic carbon (DOC) and inorganic carbon (DIC) from seawater samples collected from the Alcyone-5 cruise in the central North Pacific Ocean in 1985. Differences between the UV-radiation techniques used here and those reported by Williams, Oeschger and Kinney (1969) to oxidize and recover the DOC from sea water are presented. UV unoxidizable DOC in these samples is discussed in a separate public…
Radiocarbon Dating of Deep-Sea Sediments
Radiocarbon dating (Libby, 1955) has been an important tool in the marine sciences since the early 1950s (eg, Arrhenius, Kjellberg & Libby, 1951; Ericson et al , 1956; Broecker, Ewing & Heezen, 1960; Emery & Bray, 1962) and the basic principles and analytic procedures of the method have changed little. In the late 1970s, the Accelerator Mass Spectrometer (AMS) method of 14 C dating was developed (Bennett et al , 1977, 1978), the major advantages …
New radiocarbon dates and Late Palaeolithic diet at Wadi Kubbaniya, Egypt
Vegetable remains are a rarity in Palueolithic contexts. These new determinations on material from southern Egypt establish securely the date of an intensive grass-tuber and fish economy in the Nile Valley towards 20,000 years ago
Operation of the NSF-Arizona Accelerator Facility for Radioisotope Analysis and Results from Selected Collaborative Research Projects
Radiocarbon dating at the Arizona accelerator facility has improved substantially in the last three years. Since starting to use graphite targets (see Jull et al , 1986), we have been able to obtain routinely a precision of ca ± 1% (ca 80 yr) for relatively modern material. Our routine technique of tuning and operating the tandem accelerator mass spectrometer (TAMS) and our method of calculating 14 C results are discussed in detail. Data on activ…
Production of Graphite Targets by Deposition from CO/H 2 for Precision Accelerator 14 C Measurements
A method has been developed at the Arizona AMS facility for production of graphite directly from CO 2 by catalytic reduction of CO/H 2 mixtures. The method is a modification of procedures discussed by Vogel et al (1984). Currents of 12 C − from these targets vary considerably, but have a median value which is 70% of that achieved from spectroscopic graphite. Precisions of ±60 to 100 yr are routinely achieved for 14 C ages of 5000-yr-old samples c…
La Jolla Measurements of Radiocarbon in South German Oak Tree-Ring Chronologies
Radiocarbon measurements made by the La Jolla laboratory on tree-ring samples from South German oak chronologies are presented. Several previously separate tree-ring series have been reduced to one absolutely dendro-dated chronology spanning the period from 4066 BC to the present and one still-floating chronology which spans the approximate period 7225 to 4125 BC. Previous estimates of the dendro-years made by the authors are compared with the de…
La Jolla Natural Radiocarbon Measurements X
The following date list covers samples dated by the La Jolla (Mt Soledad) Radiocarbon Laboratory from January 1979 through August 1982. Most archaeologic, most geologic, and some geochemical samples measured during that period are included here. Results of 14 C analyses of samples of tree rings, banded coral rings, and Antarctic seawater dissolved inorganic carbon measured during this period will be published elsewhere. Because of the cessation o…
The Question of Diffuse Secondary Growth of Palm Trees
14 C activity measurements were used to investigate the growth pattern of the stem of a palm tree ( Cocos nucifera ) which does not form annual rings. The results reveal that there was no diffuse secondary growth (thickening of the stem) over the entire mature stem during the last 25 years of growth, with the exception of a restricted zone in the center at medium height
La Jolla Natural Radiocarbon Measurements IX
The following date list covers samples dated by the La Jolla Radiocarbon Laboratory during calendar year 1978. All archaeologic, all geologic, and some geochemical and botanical samples measured during that period are included here. Recent measurements of 14 C in tree rings and in annual coral rings will be published elsewhere. Plots and discussion of data for corals from Belize and Florida have been published already by Druffel (1980)
Computer-Matched Radiocarbon Dates of Floating Tree-Ring Series
The absolute time of growth of a floating tree-ring series is determined by computer, by first fitting a curve to the 14 C ages of tree-ring dated wood and then by matching the 14 C ages of the floating tree-ring series to that curve. The results obtained by this matching procedure are given here for five floating European oak chronologies for which 14 C dates have been published previously by Suess (1978). Three of these five floating series hav…
La Jolla Natural Radiocarbon Measurements VIII
The following date list covers certain samples dated by this laboratory from Nov 1975 through December 1977. All archaeological, all geological, and some of the geochemical samples measured during that period are included here. Measurements of tree-ring samples analyzed through Sept 1977 have been published previously (Suess, 1978); later measurements of wood samples will be included in the next list. Data and interpretation of 14 C in the CaCO 3…
La Jolla Measurements of Radiocarbon in the Oceans
The La Jolla Radiocarbon Laboratory has measured carbon-14 concentrations in seawater samples collected from 1957 through 1972. The dissolved inorganic carbon in seawater was extracted on board research vessels and was returned to the laboratory for processing and measurement. Both surface and sub-surface samples were collected, primarily from the Pacific Ocean, but also from the Indian Ocean. The purpose of the seawater measurements was to deter…
La Jolla Natural Radiocarbon Measurements VII
Radiocarbon dating of many types of samples has continued at the La Jolla Radiocarbon Laboratory since the last date list was published (Bien and Pandolfi, 1972). Since the 1969 relocation of the laboratory to its present location on Mt Soledad, at least 5 low-level 14 C systems have generally been in operation. The laboratory has continued to employ acetylene gas proportional counting. Samples were usually measured for 2 to 3 days in each of 2 d…
