  • Holocene glacier history of northeastern Cordillera Darwin, southernmost South America (55°S)

    Open AccessScott A Reynhout, Michael R Kaplan et al.ARTICLEQuaternary Research2022

    In the Cordillera Darwin, southernmost South America, we used 10 Be and 14 C dating, dendrochronology, and historical observations to reconstruct the glacial history of the Dalla Vedova valley from deglacial time to the present. After deglacial recession into northeastern Darwin and Dalla Vedova, by ~16 ka, evidence indicates a glacial advance at ~13 ka coeval with the Antarctic Cold Reversal. The next robustly dated glacial expansion occurred at…

  • Glacial geomorphology of the Strait of Magellan ice lobe, southernmost Patagonia, South America

    Open AccessRodrigo L Soteres, Carly Peltier et al.ARTICLEJournal of Maps2020

    We present a geomorphic map of the landforms created by the Patagonian Ice Sheet during the local Last Glacial Maximum and perhaps prior glaciations in southernmost Patagonia. Building on prior work, the new mapping focuses in unprecedented detail on the right lateral and frontal landforms formed by the Strait of Magellan ice lobe. We produced the map using aerial orthophotography, Sentinel-2 and SPOT satellite imagery, ALOS PALSAR digital elevat…

  • Late glacial fluctuations of the Laurentide Ice Sheet in the White Mountains of Maine and New Hampshire, U.S.A.

    Open AccessGordon Bromley, Brenda L Hall et al.ARTICLEQuaternary Research2015

    Prominent moraines deposited by the Laurentide Ice Sheet in northern New England document readvances, or stillstands, of the ice margin during overall deglaciation. However, until now, the paucity of direct chronologies over much of the region has precluded meaningful assessment of the mechanisms that drove these events, or of the complex relationships between ice-sheet dynamics and climate. As a step towards addressing this problem, we present a…

  • Major ice sheet response in eastern New England to a cold North Atlantic region, ca. 16–15 cal ka BP

    Open AccessMichael R KaplanARTICLEQuaternary Research2007

    A large ice sheet still covered almost all of Maine and eastern New England until ca. 15 cal ka BP, reaching south of 45 °S, despite rising summer insolation intensity and major ice recession elsewhere outside the North Atlantic region. Furthermore, the well-studied moraine belt along eastern coastal Maine, including the prominent Pineo Ridge delta/moraine complex and Pond Ridge moraine, indicates repeated readvances and stillstands between ca. 1…

  • Spatial and temporal variability of Holocene temperature in the North Atlantic region

    Open AccessMichael R Kaplan, Alexander P WolfeARTICLEQuaternary Research2006

    The early Holocene climate of the North Atlantic region was influenced by two boundary conditions that were fundamentally different from the present: the presence of the decaying Laurentide Ice Sheet (LIS) and higher than present summer solar insolation. In order to assess spatial and temporal patterns of Holocene climate evolution across this region, we collated quantitative paleotemperature records at sub-millennial resolution and synthesized t…

  • Cosmogenic nuclide chronology of pre-last glacial maximum moraines at Lago Buenos Aires, 46 S, Argentina

    Open AccessMichael R Kaplan, Daniel C Douglass et al.ARTICLEQuaternary Research2005

    At Lago Buenos Aires, Argentina, 10 Be, 26 Al, and 40 Ar/ 39 Ar ages range from 190,000 to 109,000 yr for two moraines deposited prior to the last glaciation, 23,000 16,000 yr ago. Two approaches, maximum boulder ages assuming no erosion, and the average age of all boulders and an erosion rate of 1.4 mm/10 3 yr, both yield a common estimate age of 150,000 140,000 yr for the two moraines. The erosion rate estimate derives from 10 Be and 26 Al conc…

  • Holocene Environmental Variability in Southern Greenland Inferred from Lake Sediments

    Open AccessMichael R Kaplan, Alexander P Wolfe et al.ARTICLEQuaternary Research2002

    Sediments from Qipisarqo Lake provide a continuous Holocene paleoenvironmental record from southern Greenland. Following deglaciation and glacio-isostatic emergence of the basin from the sea ∼9100 cal yr B.P., proxies of lake paleoproductivity, including biogenic silica and organic matter, increased markedly until 6000 cal yr B.P. and thereafter remained stable over the ensuing warm three millennia. Subsequent decreases in these proxies, most dra…
