  • Sudden freshening and cooling of western North Atlantic slope water at the onset of the Little Ice Age based on magnesium-to-calcium ratio and oxygen stable isotope record

    Open AccessWai Ching Rachel Chu, Tiffany Audet et al.ARTICLEQuaternary Research2026

    The Little Ice Age (LIA, ∼1400–1850 CE) was characterized by colder winters and more frequent extreme weather events in the Northern Hemisphere. While changes in ocean circulation likely contributed to global cooling, the specific mechanisms remain poorly understood. Here, we investigate how ocean circulation changed before, during, and after the LIA using marine sediment cores from the Laurentian Channel in the lower St. Lawrence Estuary. We fir…

  • Multi-proxy reconstruction of climate changes in the Lower St. Lawrence Estuary, Canada, during the Middle and Late-Holocene

    Open AccessXiner Wu, Mathieu Lemay-Tougas et al.ARTICLEThe Holocene2023Referencias: 8

    The micropaleontological and palynological content, and geochemical and isotopic composition of a marine sediment core collected off Pointe-des-Monts in eastern Québec, Canada, reveal regional palaeoclimatic and paleoceanographic conditions in the Lower St. Lawrence Estuary over the last ~8200 years. The pollen and spore content allows comparison with the terrestrial palynostratigraphy, whereas dinoflagellate cysts and benthic foraminifera are us…

  • Palynological evidence of sea-surface conditions in the Barents Sea off northeast Svalbard during the postglacial period

    Open AccessCamille Brice, Anne De Vernal et al.ARTICLEQuaternary Research2022

    Postglacial changes in sea-surface conditions, including sea-ice cover, summer temperature, salinity, and productivity were reconstructed from the analyses of dinocyst assemblages in core S2528 collected in the northwestern Barents Sea. The results show glaciomarine-type conditions until about 11,300 ± 300 cal yr BP and limited influence of Atlantic water at the surface into the Barents Sea possibly due to the proximity of the Svalbard-Barents Se…

  • Pacific walrus diet across 4000 years of changing sea ice conditions

    Open AccessCasey T Clark, Lara Horstmann et al.ARTICLEQuaternary Research2022

    Declining sea ice is expected to change the Arctic's physical and biological systems in ways that are difficult to predict. This study used stable isotope compositions (δ 13 C and δ 15 N) of archaeological, historic, and modern Pacific walrus ( Odobenus rosmarus divergens ) bone collagen to investigate the impacts of changing sea ice conditions on walrus diet during the last ~4000 yr. An index of past sea ice conditions was generated using dinocy…

  • The signal of climate changes over the last two millennia in the Gulf of St. Lawrence, eastern Canada

    Open AccessXiner Wu, Anne De Vernal et al.ARTICLEQuaternary Research2022

    Climate changes over the past two millennia in the central part of the Gulf of St. Lawrence are documented in this paper with the aim of determining and understanding the natural climate variability and the impact of anthropogenic forcing at a regional scale. The palynological content (dinocysts, pollen, and spores) of the composite marine sediment core MSM46-03 collected in the Laurentian Channel was used to reconstruct oceanographic and climati…

  • Historical Perspectives on Exceptional Climatic Years at the Labrador/Nunatsiavut Coast 1780 to 1950

    Open AccessMarie‐Michèle Ouellet‐Bernier, Anne De Vernal et al.ARTICLEQuaternary Research2021

    This interdisciplinary study presents a human perspective on climatic variations by combining documentary, discursive, instrumental, and proxy data. Historical sources were used to characterize climate variations along the coast of Labrador/Nunatsiavut during the 19 th century and the first half of the 20 th century. Written and early instrumental archives provided original information on the state and perception of climate before the establishme…

  • The archaeology of climate change

    Open AccessA Burke, Matthew Peros et al.ARTICLEProceedings of the National…2021

    Anthropogenic climate change is currently driving environmental transformation on a scale and at a pace that exceeds historical records. This represents an undeniably serious challenge to existing social, political, and economic systems. Humans have successfully faced similar challenges in the past, however. The archaeological record and Earth archives offer rare opportunities to observe the complex interaction between environmental and human sys…

  • Postglacial paleoceanography and paleoenvironments in the northwestern Barents Sea

    Open AccessElena Ivanova, Е В Иванова et al.ARTICLEQuaternary Research2019

    The Barents Sea offers a suitable location for documenting advection of warm and saline Atlantic Water (AW) into the Arctic and its impact on deglaciation and postglacial conditions. We investigate the timing, succession, and mechanisms of the transition from proximal glaciomarine to marine environment in the northwestern Barents Sea. Two studied sediment cores demonstrate diachronous retreat of the grounded ice sheet from the Kvitøya Trough (cor…

  • Sea surface conditions in the southern Nordic Seas during the Holocene based on dinoflagellate cyst assemblages

    Open AccessNicolas Van Nieuwenhove, Astrid Baumann et al.ARTICLEThe Holocene2016Referencias: 28

    Dinoflagellate cyst (dinocyst) records from the southern Nordic Seas were compiled in order to evaluate the evolution of upper ocean conditions, on a millennial timescale and supported by a highly resolved record from the Vøring Plateau. After the transitional phase from the last deglaciation, three main phases define the Holocene. The early Holocene (>7.5 ka BP) features important numbers of cool-temperate species dominated by Nematosphaeropsis …

  • Diachronous evolution of sea surface conditions in the Labrador Sea and Baffin Bay since the last deglaciation

    Open AccessOlivia Gibb, Olivia T Gibb et al.ARTICLEThe Holocene2015Referencias: 24

    Assessing changes in sea surface conditions due to the effects of past freshwater outflow through Baffin Bay and Davis Strait to the Labrador Sea, hereafter referred to as the Baffin Bay corridor, is relevant in understanding the variability in Labrador Sea Water (LSW) formation. Here, regional changes in oceanographic circulation and sea surface conditions are reconstructed based on organic-walled dinoflagellate cyst (dinocyst) assemblages from …

  • Paleoceanographic changes in the Disko Bugt area, West Greenland, during the Holocene

    Open AccessMarie‐Michèle Ouellet‐Bernier, Marie-Michèle Ouellet-Bernier et al.ARTICLEThe Holocene2014Citada por: 2Referencias: 19

    Micropaleontological analyses of a sediment core raised in Disko Bugt (West of Greenland) were undertaken in order to document paleoceanographical changes in the eastern Baffin Bay during the Holocene. The modern analogue technique (MAT) applied to dinocyst assemblages provided information on paleo-sea-surface conditions, whereas isotopic analyses of benthic foraminifers aimed at documenting the ‘deep’ water mass occupying the site. During the ea…

  • Evidence for large-amplitude biome and climate changes in Atlantic Canada during the last interglacial and mid-Wisconsinan periods

    Open AccessBianca Fréchette, Anne De VernalARTICLEQuaternary Research2013

    Last interglacial and mid Wisconsinan pollen data from sedimentary sequences of Cape Breton Island in Atlantic Canada were analyzed to reconstruct biome and climate conditions. Our results show warm and humid climate with mean annual temperature 6–7°C higher than today, up to 15–20% more sunshine and significantly longer growing season that fostered growth of temperate trees during the optimum of the last interglacial. The northern limit of the d…

  • Paleoceanographic changes and calcium carbonate dissolution in the central Fram Strait during the last 20 ka

    Open AccessKatarzyna Zamelczyk, Tine L Rasmussen et al.ARTICLEQuaternary Research2012

    A deep-sea sediment core covering the last 20 ka and located between the Polar and the Arctic fronts in the marginal ice zone (MIZ) of the central Fram Strait has been investigated for changes in paleoceanography and calcium carbonate preservation. The reconstruction is based on the distribution patterns of planktic foraminifera, mean shell weight and the degree of fragmentation of their shells, stable isotopes and other geochemical and sedimento…

  • Greenland climate change

    Open AccessValérie Masson‐delmotte, Didier Swingedouw et al.ARTICLEWiley Interdisciplinary Reviews…2012Citada por: 2Referencias: 27

    Climate archives available from deep sea and marine shelf sediments, glaciers, lakes, and ice cores in and around Greenland allow us to place the current trends in regional climate, ice sheet dynamics, and land surface changes in a broader perspective. We show that, during the last decade (2000s), atmospheric and sea surface temperatures are reaching levels last encountered millennia ago, when northern high latitude summer insolation was higher d…

  • Comparison of marine and terrestrial Holocene climatic reconstructions from northeastern North America

    Open AccessMasato Sawada, Konrad Gajewski et al.ARTICLEThe Holocene1999Referencias: 2

    Quantitative climate reconstructions based on marine dinocysts and terrestrial pollen sequences are consistent through the Holocene in northeastern North America. Principal components analysis (PCA) indicates a large-scale climate signal in the dinocysts and pollen. The combined and separate analyses of marine and nearby terrestrial pollen sequences from Hudson Bay, Labrador and the St Lawrence estuary differentiate tun dra, boreal forest and dec…

  • Palynological Evidence of Climatic and Oceanographic Changes in the North Sea during the Last Deglaciation

    Open AccessAndre Rochon, Anne De Vernal et al.ARTICLEQuaternary Research1998

    Palynological analyses performed on cores from the Norwegian Channel (Troll 8903) led to reconstruction of the late-glacial variations in sea-surface conditions using dinoflagellate cyst data and permitted direct correlation with the vegetation history of northwestern Europe derived from pollen assemblages. By ∼15,000 yr B.P., ice rapidly receded from the Norwegian shelf and relatively warm summer conditions prevailed in surface waters. A first l…
