  • Latest Pleistocene and Holocene local glacial history of Baranof Island, southeast Alaska

    Open AccessTessa McDonald, Jason P BrinerARTICLEQuaternary Research2026

    New cosmogenic 10 Be exposure ages and a proglacial lake sediment archive provide the first record of local ice cover following the deglaciation of the Cordilleran Ice Sheet (CIS) in southeast Alaska. Exposure ages from Necker Bay corroborate existing evidence for a CIS deglaciation age of ∼15–14 ka from the outer coast of Baranof Island. We date retreat farther inland on the western and eastern flanks of the island to the Early Holocene, providi…

  • A new relative sea-level curve from Inglefield Land, northwest Greenland

    Open AccessKarlee K Prince, Jason P BrinerARTICLEQuaternary Research2026

    We report a new relative sea level curve from Inglefield Land, northwest Greenland, to investigate the transition from maximum to minimum loading across Nares Strait. We sampled marine bivalves and terrestrial macrofossils for radiocarbon dating from raised marine terraces in Rensselaer Valley, Inglefield Land (78.58°N, 70.71°W) to constrain relative sea level through the Holocene. The oldest terrestrial macrofossil of 9010–8650 cal yr BP provide…

  • The size of the Greenland Ice Sheet during Marine Isotope Stage 3

    Open AccessJason P Briner, Jason Briner et al.ARTICLEQuaternary Research2025

    Ice-sheet volume during Marine Isotope Stage (MIS) 3 (57–29 ka) is controversial. Several recent studies have proposed that the Greenland Ice Sheet was smaller during MIS 3 than it is today based on radiocarbon ages of molluscan bivalve shells reworked into sedimentary deposits adjacent to the present ice margin. Such a result contrasts with available records of MIS 3 climate, ice volume, and sea level. We revisited a site previously interpreted …

  • Greenland-wide accelerated retreat of peripheral glaciers in the twenty-first century

    Open AccessL J Larocca, M Twining–Ward et al.ARTICLENature Climate Change2023

    The long-term response of Greenland’s peripheral glaciers to climate change is widely undocumented. Here we use historical aerial photographs and satellite imagery to document length fluctuations of >1,000 land-terminating peripheral glaciers in Greenland over more than a century. We find that their rate of retreat over the last two decades is double that of the twentieth century, indicating a ubiquitous transition into a new, accelerated state o…

  • Cosmogenic 10 Be exposure dating of Bull Lake and Pinedale moraine sequences in the upper Arkansas River valley, Colorado Rocky Mountains, USA

    Open AccessA D Schweinsberg, Jason P Briner et al.ARTICLEQuaternary Research2020

    Many formerly glaciated valleys in the western United States preserve detailed glacial features that span the penultimate glaciation through the last deglaciation; however, numerical age control is limited in many of these systems. We report 35 new cosmogenic 10 Be surface exposure ages of moraine boulders in the Sawatch Range, Colorado. Eight ages suggest Bull Lake moraines in Lake Creek (range: 132–120 ka, n = 4) and Clear Creek (range: 187–133…

  • New constraints on the last deglaciation of the Cordilleran Ice Sheet in coastal Southeast Alaska

    Open AccessAlia J Lesnek, Jason P Briner et al.ARTICLEQuaternary Research2020

    Understanding marine-terminating ice sheet response to past climate transitions provides valuable long-term context for observations of modern ice sheet change. Here, we reconstruct the last deglaciation of marine-terminating Cordilleran Ice Sheet (CIS) margins in Southeast Alaska and explore potential forcings of western CIS retreat. We combine 27 new cosmogenic 10 Be exposure ages, 13 recently published 10 Be ages, and 25 new 14 C ages from rai…

  • Assessing ice margin fluctuations on differing timescales

    Open AccessSamuel E Kelley, Jason P Briner et al.ARTICLEThe Holocene2018Citada por: 1Referências: 13

    The observational record of ice margin position reveals asynchrony in both the timing and magnitude of Greenland Ice Sheet (GrIS) margin fluctuations and illustrates the complex reactions of ice sheets to climatic perturbations. In this study, we reconstruct the timing and pattern of middle- and late-Holocene GrIS margin fluctuations at two locations, ~190 km apart, in central West Greenland using radiocarbon-dated sediment cores from proglacial-…

  • Holocene summer temperature reconstruction from sedimentary chlorophyll content, with treatment of age uncertainties, Kurupa Lake, Arctic Alaska

    Open AccessBrandon Reed Boldt, Darrell S Kaufman et al.ARTICLEThe Holocene2015Citada por: 3Referências: 6

    Quantitative records of pre-industrial temperature changes are fundamental for understanding long-term natural climate variability. We used visible reflectance spectroscopy to measure chlorophyll content (and its derivatives) in a sediment core from Kurupa Lake, north-central Brooks Range, Alaska, to reconstruct summer temperature and the number of annual non-freezing days over the past 5.7 ka. A calibration-in-time approach was used to convert d…

  • The deglaciation and neoglaciation of Upernavik Isstrøm, Greenland

    Open AccessJason P Briner, Lena Håkansson et al.ARTICLEQuaternary Research2013

    We constrain the history of the Greenland Ice Sheet margin during the Holocene at Upernavik Isstrøm, a major ice stream in northwestern Greenland. Radiocarbon-dated sediment sequences from proglacial-threshold lakes adjacent to the present ice margin constrain deglaciation of the sites to older than 9.6 ± 0.1 ka. This age of deglaciation is confirmed with 10 Be ages of 9.9 ± 0.1 ka from an island adjacent to the historical ice position. The lake …

  • Be data from meltwater channels suggest that Jameson Land, east Greenland, was ice-covered during the last glacial maximum

    Open AccessLena Håkansson, Jason P Briner et al.ARTICLEQuaternary Research2011

    Along the northeast Greenland continental margin, bedrock on interfjord plateaus is highly weathered, whereas rock surfaces in fjord troughs are characterized by glacial scour. Based on the intense bedrock weathering and lack of glacial deposits from the last glaciation, interfjord plateaus have long been thought to be ice-free throughout the last glacial maximum (LGM). In recent years there is growing evidence from shelf and fjord settings that …

  • A 2000-yr-long multi-proxy lacustrine record from eastern Baffin Island, Arctic Canada reveals first millennium AD cold period

    Open AccessElizabeth K Thomas, Jason P Briner et al.ARTICLEQuaternary Research2011

    We generate a multi-proxy sub-centennial-scale reconstruction of environmental change during the past two millennia from Itilliq Lake, Baffin Island, Arctic Canada. Our reconstruction arises from a finely subsectioned 210 Pb- and 14 C-dated surface sediment core and includes measures of organic matter (e.g., chlorophyll a ; carbon–nitrogen ratio) and insect (Diptera: Chironomidae) assemblages. Within the past millennium, the least productive, and…

  • Moraine chronosequence of the Donnelly Dome region, Alaska

    Open AccessAri Matmon, Jason P Briner et al.ARTICLEQuaternary Research2010

    We present 10 Be exposure ages from moraines in the Delta River Valley, a reference locality for Pleistocene glaciation in the northern Alaska Range. The ages are from material deposited during the Delta and Donnelly glaciations, which have been correlated with MIS 6 and 2, respectively. 10 Be chronology indicates that at least part of the Delta moraine stabilized during MIS 4/3, and that the Donnelly moraine stabilized ∼ 17 ka. These ages correl…

  • Paleoecological evidence for abrupt cold reversals during peak Holocene warmth on Baffin Island, Arctic Canada

    Open AccessYarrow Axford, Jason P Briner et al.ARTICLEQuaternary Research2009

    A continuous record of insect (Chironomidae) remains preserved in lake sediments is used to infer temperature changes at a small lake in Arctic Canada through the Holocene. Early Holocene summers at the study site were characterized by more thermophilous assemblages and warmer inferred temperatures than today, presumably in response to the positive anomaly in Northern Hemisphere summer insolation. Peak early Holocene warmth was interrupted by two…

  • Recent Warming Reverses Long-Term Arctic Cooling

    Open AccessDarrell S Kaufman, David P Schneider et al.ARTICLEScience2009

    Climate Reversal The climate and environment of the Arctic have changed drastically over the short course of modern observation. Kaufman et al. (p. 1236 ) synthesized 2000 years of proxy data from lakes above 60° N latitude with complementary ice core and tree ring records, to create a paleoclimate reconstruction for the Arctic with a 10-year resolution. A gradual cooling trend at the start of the record had reversed by the beginning of the 20th …

  • A multi-proxy lacustrine record of Holocene climate change on northeastern Baffin Island, Arctic Canada

    Open AccessJason P Briner, Neal Michelutti et al.ARTICLEQuaternary Research2006

    Reconstructions of past environmental changes are critical for understanding the natural variability of Earth's climate system and for providing a context for present and future global change. Radiocarbon-dated lake sediments from Lake CF3, northeastern Baffin Island, Arctic Canada, are used to reconstruct past environmental conditions over the last 11,200 years. Numerous proxies, including chironomid-inferred July air temperatures, diatom-inferr…

  • Preservation of Arctic landscapes overridden by cold-based ice sheets

    Open AccessP Thompson Davis, Jason P Briner et al.ARTICLEQuaternary Research2006

    For nearly 40 years, a massive, well-preserved glaciomarine delta more than 54,000 years old and ancillary landforms have formed the cornerstone of models positing limited ice-sheet extent in Arctic Canada during the late Wisconsinan. We present exposure ages for large boulders on the delta surface, which coupled with preservation of relict landforms demonstrate that the region was covered by minimally erosive, cold-based ice during the late Wisc…

  • Late Pleistocene Cosmogenic 36 Cl Glacial Chronology of the Southwestern Ahklun Mountains, Alaska

    Open AccessJason P Briner, Terry W Swanson et al.ARTICLEQuaternary Research2001

    Thirty-two cosmogenic 36 Cl surface exposure ages constrain the timing of two late Pleistocene glacial advances in the western Ahklun Mountains, southwestern Alaska. Boulders were sampled from one early Wisconsin ( sensu lato ) and six late Wisconsin moraines deposited by ice-cap outlet glaciers and local alpine glaciers. Four moraine boulders deposited during an extensive early Wisconsin ice-cap outlet glacier advance have a mean surface exposur…

  • Late Pleistocene Glaciation of the Southwestern Ahklun Mountains, Alaska

    Open AccessJason P Briner, Darrell S KaufmanARTICLEQuaternary Research2000

    Glacial deposits in the southwestern Ahklun Mountains, southwestern Alaska, record two major glacier advances during the late Pleistocene. The Arolik Lake and Klak Creek glaciations took place during the early and late Wisconsin, respectively. During the Arolik Lake glaciation, outlet glaciers emanated from an ice cap centered over the central portion of the Ahklun Mountains and expanded beyond the present coast. During the Klak Creek glaciation,…
