  • A Holocene Record of Atmospheric Dust Deposition on the Penny Ice Cap, Baffin Island, Canada

    Open AccessChristian Zdanowicz, Christian M Zdanowicz et al.ARTICLEQuaternary Research2000

    An >11,550-yr-long record of atmospheric dust deposition was developed from an ice core (P95) drilled through the Penny ice cap, Baffin Island. The P95 record documents environmental changes that affected the production and transport of dust in the eastern Canadian Arctic during the late Pleistocene and Holocene. Dust deposition on the Penny ice cap was greatest in late-glacial time when the climate was dry and windy and comparatively low in the …

  • Is There Evidence for Solar Forcing of Climate in the Gisp2 Oxygen Isotope Record?

    Open AccessM Stuiver, Thomas F Braziunas et al.ARTICLEQuaternary Research1997

    Changes in solar constant over an 11 yr cycle suggest a certain, but limited, degree of solar forcing of climate. The high-resolution climate (oxygen isotope) record of the Greenland GISP2 (Greenland Ice Sheet Project 2) ice core has been analyzed for solar (and volcanic) influences. The atmospheric 14 C record is used as a proxy of solar change and compared to the oxygen isotope profile in the GISP2 ice core. An annual oxygen isotope profile is …

  • Arctic Environmental Change of the Last Four Centuries

    Open AccessJonathan T Overpeck, J Overpeck et al.ARTICLEScience1997

    A compilation of paleoclimate records from lake sediments, trees, glaciers, and marine sediments provides a view of circum-Arctic environmental variability over the last 400 years. From 1840 to the mid-20th century, the Arctic warmed to the highest temperatures in four centuries. This warming ended the Little Ice Age in the Arctic and has caused retreats of glaciers, melting of permafrost and sea ice, and alteration of terrestrial and lake ecosys…

  • A 110,000-Yr Record of Explosive Volcanism from the Gisp2 (Greenland) Ice Core

    Open AccessGregory A Zielinski, Paul A Mayewski et al.ARTICLEQuaternary Research1996

    The time series of volcanically produced sulfate from the GISP2 ice core is used to develop a continuous record of explosive volcanism over the past 110,000 yr. We identified ∼850 volcanic signals (700 of these from 110,000 to 9000 yr ago) with sulfate concentrations greater than that associated with historical eruptions from either equatorial or mid-latitude regions that are known to have perturbed global or Northern Hemisphere climate, respecti…

  • Late Quaternary Vegetation and Climate of the Wind River Range, Wyoming

    Open AccessPatricia L Fall, P Thompson Davis et al.ARTICLEQuaternary Research1995

    Sediments from Rapid Lake document glacial and vegetation history in the Temple Lake valley of the Wind River Range, Wyoming over the past 11,000 to 12,000 yr. Radiocarbon age determinations on basal detrital organic matter from Rapid Lake (11,770 ± 710 yr B.P.) and Temple Lake (11,400 ± 630 yr B.P.) bracket the age of the Temple Lake moraine, suggesting that the moraine formed in the late Pleistocene. This terminal Pleistocene readvance may be r…

  • Evidence of the Eldgjá (Iceland) eruption in the Gisp2 Greenland ice core

    Open AccessGregory A Zielinski, Mark S Germani et al.ARTICLEThe Holocene1995Citada por: 4Referências: 1

    Glaciochemical studies and the evaluation of tephra in the GISP2 ice core provide information on the characteristics and potential environmental and climatic effects of the mid- to late AD 930s voluminous fissure eruption of Eldgjá, Iceland. The similarity in the chemical composition of basaltic glass shards found in a section of core dated at AD 938 ± 4 compared to proximal glass from the Eldgjá eruption verifies the presence of Eldgjá debris. A…

  • Characteristics and Possible Source of a 1479 A.D. Volcanic Ash Layer in a Greenland Ice Core

    Open AccessR Joseph Fiacco, Julie M Palais et al.ARTICLEQuaternary Research1993

    A microparticle concentration peak in a GISP2 ice core contains volcanic glass shards of rhyolitic composition that correspond in age to the 1479-1480 A.D. Mt. St. Helens Wn eruption. These glass shards are compositionally similar to the Wn tephra and constitute 83% of the total particle population. The shards are very coarse-grained (up to 40 μm diameter), suggesting rapid transport from their source to Greenland. A major sulfate peak in the ice…
