Precise Temporal Correlation of Holocene Mollusk Shells Using Sclerochronology
Annual growth bands of mollusk shells record several types of paleoenvironmental information, including geochemical proxies for water properties and morphological characteristics of growth and mortality. Sclerochronology, the marine counterpart of dendrochronology, offers a way to link individual shells together to form long continuous records of such parameters. It also allows for precise dating of recent shells and identification of contemporan…
An abrupt drowning of the Black Sea shelf
During latest Quaternary glaciation, the Black Sea became a giant freshwater lake. The surface of this lake drew down to levels more than 100 m below its outlet. When the Mediterranean rose to the Bosporus sill at 7,150 yr BP1, saltwater poured through this spillway to refill the lake and submerge, catastrophically, more than 100,000 km2 of its exposed continental shelf. The permanent drowning of a vast terrestrial landscape may possibly have acc…
Woce AMS Radiocarbon I
AMS radiocarbon results from the World Ocean Circulation Experiment in the Pacific Ocean show dramatic changes in the inventory and distribution of bomb-produced 14 C since the time of the GEOSECS survey (8/73–6/74). Near-surface Δ 14 C values for the eastern portion of both the northern and southern subtropical gyres decreased by 25–50‰, with the change being greater in the north. Equatorial near-surface values have increased by ca. 25‰. Changes…
AMS 14 C age constraints on geoglyphs in the lower colorado river region, arizona and california
Giant ground figures are widespread in the lower Colorado River area of southwestern North America, yet their chronology has remained unconstrained by numerical ages. Thirteen AMS 14 C measurements reported here indicate that geoglyphs were made from before ̃A. D. 1200 to before ̃900 B. C. We account for potential contamination from prior organics in weathering rinds. All other potential errors point to 14 C dates being minimum‐limiting ages for …
A new hypothesis for the Holocene appearance of coccolithophores in the Black Sea
A recent accelerator mass spectrometer (AMS) radiocarbon study of Black Sea Holocene sediments has resolved a long-standing chronology controversy involving radioisotope and varve- counting methodologies. The revised chronology combined with model results of the salinity evolution of the Black Sea since the last glacial maximum does not support the hypothesis of a salinity-controlled Holocene invasion of the Black Sea by coccolithophores, a plank…
AMS-Graphite Target Production Methods at the Woods Hole Oceanographic Institution During 1986–1991
In July 1986, an AMS radiocarbon target preparation laboratory was established at the Woods Hole Oceanographic Institution to produce graphite to be analyzed at the NSF-Accelerator Facility for Radioisotope Analysis at the University of Arizona (Tucson). By June 1991, 923 graphite targets had been prepared and 847 analyzed. Our lab procedures during this time included the careful documentation of weights of all starting samples, catalysts and fin…
Reconstruction of Caribbean climate change over the past 10,500 years
Assessing the Global Meltwater Spike
L. V. Worthington (1968, Meteorological Monographs 8, 63–67) hypothesized that a low-salinity lid covered the entire world ocean. By deconvolving isotopic curves from the western equatorial Pacific and equatorial Atlantic, W. H. Berger, R. F. Johnson, and J. S. Killingley (1977), Nature (London) 269, 661–663) and W. H. Berger (1978, Deep-Sea Research 25, 473–480) reconstructed “meltwater spikes” similar to those actually observed in the Gulf of M…
