Valley floor climate observations from the McMurdo dry valleys, Antarctica, 1986–2000
[1] Climate observations from the McMurdo dry valleys, East Antarctica are presented from a network of seven valley floor automatic meteorological stations during the period 1986 to 2000. Mean annual
Thermal state of permafrost in North America: a contribution to the international polar year
A snapshot of the thermal state of permafrost in northern North America during the International Polar Year (IPY) was developed using ground temperature data collected from 350 boreholes. More than
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,
Antarctic climate cooling and terrestrial ecosystem response
TLDR
Data from the dry valleys are presented representing evidence of rapid terrestrial ecosystem response to climate cooling in Antarctica, including decreased primary productivity of lakes and declining numbers of soil invertebrates, which poses challenges to models of climate and ecosystem change.
Climatological observations and predicted sublimation rates at Lake Hoare, Antarctica.
TLDR
The first year-round observations available for any site in Taylor Valley are reported on and a model incorporating nonsteady molecular diffusion into Kolmogorov-scale eddies in the interfacial layer and similarity-theory flux-profiles in the surface sublayer, is used to determine the rate of ice sublimation from the acquired meteorological data.
Large Arctic Temperature Change at the Wisconsin-Holocene Glacial Transition
Analysis of borehole temperature and Greenland Ice Sheet Project II ice-core isotopic composition reveals that the warming from average glacial conditions to the Holocene in central Greenland was
Sea ice loss enhances wave action at the Arctic coast
Erosion rates of permafrost coasts along the Beaufort Sea accelerated over the past 50 years synchronously with Arctic‐wide declines in sea ice extent, suggesting a causal relationship between the
The canyon system on Mars
Individual Martian equatorial troughs are described, and their stratigraphy, geomorphology and structure are discussed. Possible origins and the overall sequence of events are addressed. Wall rock,
The WAIS Divide deep ice core WD2014 chronology – Part 1: Methane synchronization (68–31 ka BP) and the gas age–ice age difference
Abstract. The West Antarctic Ice Sheet Divide (WAIS Divide, WD) ice core is a newly drilled, high-accumulation deep ice core that provides Antarctic climate records of the past ∼68 ka at
