Woce Radiocarbon IV
The World Ocean Circulation Experiment, carried out between 1990 and 1997, provided the most comprehensive oceanic survey of radiocarbon to date. Approximately 10,000 samples were collected in the Pacific Ocean by U.S. investigators for both conventional large volume p counting and small volume accelerator mass spectrometry analysis techniques. Results from six cruises are presented. The data quality is as good or better than previous large-scale…
Fast and Complete CO 2 -to-Graphite Conversion for 14 C Accelerator Mass Spectrometry
With Fe powder as a catalyst, CO 2 is completely converted to graphite within 90 minutes. The reaction proceeds at 650°C with an excess of H 2 . The reaction rate is enlarged by forced circulation and by keeping the water vapor pressure very low. The graphite samples obtained, consisting of 5mg of carbon, almost immediately produce stable 12 C − currents of the order of 20–30μA in the sputter source of a Van de Graaff accelerator. The currents ca…
Stockholm Natural Radiocarbon Measurements V
This date list includes samples and sample series finished between January and November 1962. It does not include samples from series not yet been completed, or samples of very limited scientific interest
Miami Natural Radiocarbon Measurements II
The C 14 dates given below are a continuation of the work presented in our first list (Miami I) using the same apparatus and techniques described previously. In addition to the dating of marine carbonate materials, however, we have extended our methods to the dating of wood and peat samples. All dated peat and wood samples have been given a standard pretreatment by successive washings with dilute HCl and 2% NaOH solution for removal of carbonates…
Stockholm Natural Radiocarbon Measurements IV
This paper is a direct continuation of the third dating list (Stockholm III), and the entire technique is virtually unchanged, using one 0.5–1 and one 1.0.1 3 atm CO 2 proportional counter. Ages are calculated according to the recommendation given in the introduction of this book, and δC 13 has been measured for unknown samples and for the different CO 2 preparations of the NBS oxalic-acid standard. Since the numerical relationship between the C …
Miami Natural Radiocarbon Measurements I
The construction of the dating apparatus started in the summer of 1960 and was completed one year later. The laboratory is located on the bottom floor of a three-story concrete-block building which has two thin concrete floors on concrete beams above the shield. The building is underlain by carbonate mud and coral rock. The geographic location is 25° 43.9′ N Lat, 80° 09.8′ W Long and only a few feet above sealevel. We use a proportional-counting …
Stockholm Natural Radiocarbon Measurements II
This paper is a list of the radiocarbon datings of geologic and archaeologic samples made during 1958 after the dating apparatus had been installed at the Geological Survey. It is a direct continuation of the first dating list (Östlund, 1957a). Some of the results of geophysical interest, measurements of a few sea water samples, have been published separately (Fonselius and Östlund, 1959); others will follow
