A chronological framework for the Holocene vegetational history of central Minnesota: the Steel Lake pollen record
Paleorecords from Minnesota and adjacent areas have often been used to evaluate large-scale climatic processes in the midcontinent of North America. However, most of these records are compromised by chronological flaws, making problematic any comparisons with climatic interpretations based on other records (e.g., GISP2 in Greenland). We report here a high-resolution pollen record with a secure ...
متن کاملSantorini eruption radiocarbon dated to 1627-1600 B.C.
Precise and direct dating of the Minoan eruption of Santorini (Thera) in Greece, a global Bronze Age time marker, has been made possible by the unique find of an olive tree, buried alive in life position by the tephra (pumice and ashes) on Santorini. We applied so-called radiocarbon wiggle-matching to a carbon-14 sequence of tree-ring segments to constrain the eruption date to the range 1627-16...
متن کاملTesting the timing of radiocarbon-dated events between proxy archives
For interpreting past changes on a regional or global scale, the timings of proxy-inferred events are usually aligned with data from other locations. However, too often chronological uncertainties are ignored in proxy diagrams and multisite comparisons, making it possible for researchers to fall into the trap of sucking separate events into one illusionary event (or vice versa). Here we largely...
متن کاملForest History of Ohio. I, Radiocarbon Dates and Pollen Stratigraphy of Silver Lake, Logan County, Ohio
Radiocarbon and pollen analysis of a sediment core (8.9 m) from Silver Lake in central Ohio indicates that deposition began in late Woodfordian time (11,000-14,000 radiocarbon years ago) and has been continuous to the present. The pollen sequence includes a basal spruce-fir pollen zone, changing abruptly to oak-elm immediately above a radiocarbon date of 9800 ±210 (OWU-39). A total of 19 radioc...
متن کاملManganese and land-use in upland catchments in Scotland.
Manganese (Mn) in surface waters is a micronutrient, but elevated concentrations are toxic to fish and impair drinking water quality. In Scotland, undesirable Mn concentrations (> 0.05 mg l(-1)) occur predominantly in upland freshwaters because the acidic pH and organic nature of catchment soils favour Mn mobilisation. The relationship between upland land-use in Scotland and Mn concentrations i...
