A Monte Carlo inverse method has been used on the temperature profiles measured down through the Greenland Ice Core Project (GRIP) borehole, at the summit of the Greenland Ice Sheet, and the Dye 3 borehole 865 kilometers farther south. The result is a 50, 000-year-long temperature history at GRIP and a 7000-year history at Dye 3. The Last Glacial Maximum, the Climatic Optimum, the Medieval Warmth, the Little Ice Age, and a warm period at 1930 A.D. are resolved from the GRIP reconstruction with… Expand

Relation of measured basal temperatures and the spatial distribution of the geothermal heat flux for the Greenland ice sheet
Abstract The thermomechanical, three-dimensional ice-sheet model SICOPOLIS is applied to the Greenland ice sheet. Simulations over two glacial–interglacial cycles are carried out, driven by aExpand
Temperatures at the base of the Laurentide Ice Sheet inferred from borehole temperature data
[1] We use temperature profiles from 4 deep (>1600 m) boreholes across Canada to determine ground surface temperature histories (GSTH's) through and after the Last Glacial Maximum (LGM). InversionExpand
High variability of Greenland surface temperature over the past 4000 years estimated from trapped air in an ice core
[1] Greenland recently incurred record high temperatures and ice loss by melting, adding to concerns that anthropogenic warming is impacting the Greenland ice sheet and in turn accelerating globalExpand
Greenland glacial history, borehole constraints, and Eemian extent
[1] We examine the extent to which observations from the Greenland ice sheet combined with three-dimensional dynamical ice sheet models and semi-Lagrangian tracer methods can be used to constrainExpand
Weichselian temperatures from geothermal heat flow data
[1] We report an analysis of geothermal heat flow density (HFD) in the Fennoscandian Shield and East European Platform showing a systematic variation with depth. The HFD data (1352 values) averagedExpand
How warm was Greenland during the last interglacial period
Abstract. The last interglacial period (LIG, ∼ 129–116 thousand years ago) provides the most recent case study of multimillennial polar warming above the preindustrial level and a response of theExpand
Canadian Arctic Permafrost Observatories: Detecting contemporary climate change through inversion of subsurface temperature time series
[1] We describe long-term permafrost temperature and climate change observatories established in the northeastern Canadian High Arctic (77°–82.5°N). Two sites have deep temperature logs (165 and 800Expand
A new method to estimate ice age temperatures
On glacial time scales, the waxing and waning of the Eurasian and North American ice sheets depend largely on variations in atmospheric temperature. As global sea level is primarily determined by theExpand
A model of the Greenland ice sheet deglaciation
The goal of this thesis is to improve our understanding of the Greenland ice sheet (GrIS) and how it responds to climate change. This was achieved using ice core records to infer elevation changes ofExpand
The Fennoscandian ice sheet during the Late Weichselian: geothermal evidence
Geothermal estimates of the ground surface temperatures for the last glacial cycle in Northern Europe have been analysed. During the Middle and Late Weichselian (55–12 kyr BP), a substantial part ofExpand


Temperature, accumulation, and ice sheet elevation in central Greenland through the last deglacial transition
We present a combined heat- and ice-flow model, constrained by measurements of temperature in the Greenland Ice Sheet Project 2 (GISP2) borehole and by the GISP2 δ18O record and depth-age scale,Expand
A search in north Greenland for a new ice-core drill site
A new deep ice-core drilling site has been identified in north Greenland at 75.12°N, 42.30°W, 316 km north-northwest (NNW) of the GRIP drill site on the summit of the ice sheet. The ice thicknessExpand
Resolving the younger Dryas event through borehole thermometry
Meltwater influxes may partly explain the low oxygen-isotope values measured in the Dye 3 and Camp Century ice cores. This has led to speculation that Greenland may not have cooled during the YoungerExpand
Palaeotemperatures still exist in the Greenland ice sheet
The temperature distribution through the Greenland ice sheet at the Dye 3 borehole is a record of the past climatic changes in the Arctic. The numerical model of the temperature distribution nowExpand
Greenland palaeotemperatures derived from GRIP bore hole temperature and ice core isotope profiles
Modelling the temperature profile along the GRIP deep bore at the summit of the Greenland ice sheet leads to conversion factors that allow interpretation of the dated stable isotope profile as aExpand
Heat flow and surface radioactivity were determined at two sites in the Precambrian shield of south Greenland. At Ivigtut heat flow q from two holes in Ketilidian (∼1700–1500 m.y.) gneisses averagedExpand
The climate signal in the stable isotopes of snow from Summit, Greenland: Results of comparisons with modern climate observations
Recent efforts to link the isotopic composition of snow in Greenland with meteorological and climatic parameters have indicated that relatively local information such as observed annual temperaturesExpand
Heat flow from the Earth's interior: Analysis of the global data set
We present a new estimate of the Earth's heat loss based on a new global compilation of heat flow measurements comprising 24,774 observations at 20,201 sites. On a 5 o x 5 o grid, the observationsExpand
Greenland ice sheet history since the last glaciation
Abstract The position of the Inland Ice margin during the late Wisconsin-Wurm glaciation (ca. 15,000 yr BP) is probably marked by offshore banks (submarine moraines?) in the Davis Strait. The historyExpand

We describe a high-precision (0.1-1.0 mK) borehole-temperature (BT) logging system developed at the United States Geological Survey (USGS) for use in remote polar regions. We discuss calibration,Expand
