  • Late Pleistocene–Holocene pollen, macrofossils, and diatoms from eastern New York state’s (USA) Rensselaer Plateau reveal multiple temperature and hydrological shifts

    Open AccessKirsten M Menking, Dorothy Peteet et al.ARTICLEQuaternary Research2026

    Sediment cores from Dyken and Shaver ponds on the Rensselaer Plateau, eastern New York state, USA, were analyzed for sediment chemistry, pollen, plant macrofossils, and diatoms to reconstruct the ecological and climate history since Laurentide ice sheet retreat of this previously unstudied region. Forests were established by 13,040 cal yr BP, and pollen records follow the well-documented northeastern U.S. sequence: Allerød interstade (mixed borea…

  • Geomagnetic Secular Variation Models for Latitude Scaling of Cosmic Ray Flux and Considerations for 10Be Exposure Dating of Laurentide Ice Sheet Retreat

    Open AccessDale V Kent, Luca Lanci et al.ARTICLEQuaternary2025

    Published cosmogenic 10Be exposure ages from the terminal moraine of the Laurentide Ice Sheet (LIS) in northeastern North America have been interpreted to date the start of the retreat of the LIS at the Last Glacial Maximum (LGM) about 25 thousand years ago (ka). In contrast, published 14C accelerator mass spectrometry (AMS) dates for terrestrial plant macrofossils in LIS basal deglacial clay deposits range back to only ~16 calibrated (cal) ka, m…

  • Placing the east-west North American aridity gradient in a multi-century context

    Open AccessDaniel A Bishop, Park Williams et al.ARTICLEEnvironmental Research Letters2021

    Instrumental records indicate a century-long trend towards drying over western North America and wetting over eastern North America. A continuation of these trends into the future would have significant hydroclimatic and socioeconomic consequences in both the semi-arid Southwest and humid East. Using tree-ring reconstructions and hydrologic simulations of summer soil moisture, we evaluate and contextualize the modern summer aridity gradient withi…

  • Climate and anthropogenic controls on blue carbon sequestration in Hudson River tidal marsh, Piermont, New York

    Open AccessDorothy Peteet, J Nichols et al.ARTICLEEnvironmental Research Letters2020

    Tidal marshes globally are experiencing erosion with sea level rise. In order to adaptively plan for essential marsh preservation, we recognize the importance of the investigation of marsh archives for the perspective they provide toward resilience. Our objective in this study is to examine the relationship of tidal marsh carbon sequestration with both climate change and human impact throughout past centuries and millennia. A Hudson River marsh s…

  • Impacts of climate and vegetation change on carbon accumulation in a south-central Alaskan peatland assessed with novel organic geochemical techniques

    Open AccessJ E Nichols, Dorothy Peteet et al.ARTICLEThe Holocene2014Citada por: 2Referencias: 4

    To constrain the effect of climate and peatland type on carbon accumulation, we reconstructed these parameters from a Holocene-length core of a Sphagnum-dominated peatland near Cordova, AK, USA. We determined peat type using a combination of peat texture and density, macrofossils, distributions of leaf-wax biomarkers, and soil pH reconstructions based on distributions of branched glycerol dialkyl glycerol tetraether lipids (brGDGTs). We produced …

  • A database and synthesis of northern peatland soil properties and Holocene carbon and nitrogen accumulation

    Open AccessJulie Loisel, Zicheng Yu et al.ARTICLEThe Holocene2014Citada por: 21Referencias: 11

    Here, we present results from the most comprehensive compilation of Holocene peat soil properties with associated carbon and nitrogen accumulation rates for northern peatlands. Our database consists of 268 peat cores from 215 sites located north of 45°N. It encompasses regions within which peat carbon data have only recently become available, such as the West Siberia Lowlands, the Hudson Bay Lowlands, Kamchatka in Far East Russia, and the Tibetan…

  • Climate and vegetation history from a 14,000-year peatland record, Kenai Peninsula, Alaska

    Open AccessMiriam C Jones, Dorothy Peteet et al.ARTICLEQuaternary Research2009

    Analysis of pollen, spores, macrofossils, and lithology of an AMS 14 C-dated core from a subarctic fen on the Kenai Peninsula, Alaska reveals changes in vegetation and climate beginning 14,200 cal yr BP. Betula expansion and contraction of herb tundra vegetation characterize the Younger Dryas on the Kenai, suggesting increased winter snowfall concurrent with cool, sunny summers. Remarkable Polypodiaceae (fern) abundance between 11,500 and 8500 ca…

  • Medieval Warming, Little Ice Age, and European impact on the environment during the last millennium in the lower Hudson Valley, New York, USA

    Open AccessDee Cabaniss Pederson, Dorothy Peteet et al.ARTICLEQuaternary Research2005

    Establishing natural climate variability becomes particularly important in large urban areas in anticipation of droughts. We present a well-dated bi-decadal record of vegetation, climate, land use, and fire frequency from a tidal marsh in the Hudson River Estuary. The classic Medieval Warm Period is evident through striking increases in charcoal and Pinus dominance from ∼800–1300 A.D., paralleling paleorecords southward along the Atlantic seaboar…

  • Late-Glacial to Early Holocene Climate Changes from a Central Appalachian Pollen and Macrofossil Record

    Open AccessMargaret Kneller, Dorothy PeteetARTICLEQuaternary Research1999

    A late-glacial to early Holocene record of pollen, plant macrofossils, and charcoal has been obtained from two cores from Browns Pond in the central Appalachians of Virginia. An AMS radiocarbon chronology defines the timing of moist and cold excursions, superimposed on the overall warming trend from 14,200 to 7500 14 C yr B.P. This site had cold, moist conditions from ca. 14,200 to 12,700 14 C yr B.P., with warming at 12,730, 11,280, and 10,050 1…

  • Antiphasing between Rainfall in Africa's Rift Valley and North America's Great Basin

    Open AccessWallace S Broecker, Dorothy Peteet et al.ARTICLEQuaternary Research1998

    The beginning of the Bølling-Allerød warm period was marked in Greenland ice by an abrupt rise in δ 18 O, an abrupt drop in dust rain, and an abrupt increase in atmospheric methane content. The surface waters in the Norwegian Sea underwent a simultaneous abrupt warming. At about this time, a major change in the pattern of global rainfall occurred. Lake Victoria (latitude 0°), which prior to this time was dry, was rejuvenated. The Red Sea, which p…

  • Extent and Timing of the Last Glacial Maximum in Southwestern Alaska

    Open AccessDaniel H Mann, Dorothy PeteetARTICLEQuaternary Research1994

    A glacier complex composed of confluent alpine glaciers, island ice caps, and piedmont lobes covered much of the Alaska Peninsula and Kodiak Island during the last glacial maximum (LGM). Because this glacier complex formed the southeastern border of Beringia, its dynamics may have been important in the timing and feasibility of the northwest coast route for human migration into lower-latitude North America. Radiocarbon dates from stratigraphic se…

  • The Mount Edgecumbe Tephra Deposits, a Marker Horizon in Southeastern Alaska Near the Pleistocene-Holocene Boundary

    Open AccessJames R Riehle, Daniel H Mann et al.ARTICLEQuaternary Research1992

    Late Pleistocene tephra deposits found from Sitka to Juneau and Lituya Bay are assigned to a source at the Mount Edgecumbe volcanic field, based on similarity of glass compositions to nearvent deposits and on thinning away from Kruzof Island. The sequence of near-vent layers is basaltic andesite and andesite at the base, rhyolite, and mixed dacite and rhyolite on top. The only breaks in the tephra sequence are two 1-mm-thick silt partings in a la…

  • Younger Dryas Climatic Reversal in Northeastern USA? AMS Ages for an Old Problem

    Open AccessDorothy Peteet, D M Peteet et al.ARTICLEQuaternary Research1990

    Late-glacial macrofossils from a 10-m core from Alpine Swamp, New Jersey, were radiocarbon dated using accelerator mass spectrometry (AMS). The arrival of the first trees to the area following deglaciation is indicated by maximum percentages of spruce pollen and a date of 12,290 ± 440 yr B.P. on a single spruce needle. Subsequent spread of deciduous hardwoods was followed by the expansion of boreal taxa, including spruce ( Picea ), fir ( Abies ),…

  • Modern Pollen Rain and Vegetational History of the Malaspina Glacier District, Alaska

    Open AccessDorothy PeteetARTICLEQuaternary Research1986

    Seventy surface pollen samples from coastal forest, coastal meadow, muskeg, tree line, and alpine tundra communities form a basis for interpreting fossil pollen assemblages in the Malaspina Glacier district, Alaska. Poflen and macrofossil analyses of three radiocarbon-dated fossil sections from Icy Cape indicate that vegetational changes resulting from plant succession can be distinguished from those of migrational and climatic origin. Vegetation…

  • Terrestrial Conditions at the Last Glacial Maximum and CLIMAP Sea-Surface Temperature Estimates

    Open AccessDavid Rind, Dorothy PeteetARTICLEQuaternary Research1985

    CLIMAP (1981, “Seasonal Reconstruction of the Earth's Surface at the Last Glacial Maximum,” Geological Society of America Map and Chart Series MC-36) boundary conditions were used as inputs to the GISS general circulation model, and the last glacial maximum (LGM) climate was simulated for six model years. The simulation was compared with snow line depression and pollen-inferred temperature data at low latitudes, specifically for Hawaii, Colombia,…
