US Geological Survey, Menlo Park, California Radiocarbon Measurements IV
The Menlo Park Radiocarbon Laboratory utilizes gas proportional counting of carbon dioxide in counters installed 9.5m below the ground surface for background reduction (Robinson, 1977, 1979; Robinson & Trimble, 1981, 1983). The reported results of geologic samples closely follow the guidelines of Stuiver and Polach (1977). The standard errors for analyses earlier than USGS-500 are based solely upon counting statistics, while later analyses includ…
Anomalous Radiocarbon Ages from a Holocene Detrital Organic Lens in Alaska and their Implications for Radiocarbon Dating and Paleoenvironmental Reconstructions in the Arctic
Eleven radiocarbon age determinations clearly show that a lens of Holocene fluvial organic debris on the Alaskan Arctic Coastal Plain contains mostly pre-Holocene organic material. Radio-carbon ages of identified plant macrofossils indicate the material was deposited about 9000 to 9500 yr B.P. Radiocarbon analyses of bulk samples from this deposit, however, range from 13,300 to 30,300 yr B.P. Most of the old organic matter seems to be in the smal…
Diatom Evidence on Wisconsin and Holocene Events in the Bering Sea
Previous work on surface (modern) sediments has defined diatom species which appear to be good indicators of various oceanographic/ecologic conditions in the North Pacific Ocean and marginal seas. Three long cores from the eastern and northern sides of the Aleutian Basin show changes in species assemblage which can be interpreted in terms of changes in the ocean environment during the last glaciation (Wisconsin) and the Holocene. The early and la…
US Geological Survey, Menlo Park, California Radiocarbon Measurements III
The analyses in this list were performed between 1977 and 1979. The laboratory utilizes gas counting of carbon dioxide in counters installed 9.5 meters below the ground surface for background reduction. The reported results closely follow the guidelines of Stuiver and Polach (1977), although the standard error for analyses earlier than USGS-500 are based solely upon counting statistics and do not include uncertainty in voltage, pressure, temperat…
US Geological Survey, Menlo Park, California, Radiocarbon Measurements II
The Menlo Park radiocarbon laboratory of the US Geological Survey began operation in January 1976 in a new building with a counting room 9.8m below the ground surface. Shielding above the counters consists of 30cm lead and 8.2m earth. The ionizing cosmic ray flux at the counters is 0.28 cpm/cm 2 . Background levels obtained thus far are summarized in Table 1
US Geological Survey, Menlo Park, California, Radiocarbon Measurements I
A radiocarbon laboratory at the US Geological Survey Western Regional Headquarters in Menlo Park, California was established in temporary rooms in March, 1976. In August, 1976 the laboratory was dismantled and moved into a new building that was designed specifically for the facility. This list contains results of operations in the temporary laboratory, which was located in the basement of a two-story building. The counter shield was 15cm lead and…
