ICE-CORE reconstructions of atmospheric methane concentrations for the past 220 kyr have revealed large variations associated with different climatic periods1-4. But the phase relationship between climate and methane has been uncertain because of dating un ...

Springer Science and Business Media LLC2012

Reconstructions of past atmospheric concentrations of greenhouse gases provide unique insight into the biogeochemical cycles and the past radiative forcing in the Earth's climate system. We present new measurements of atmospheric nitrous oxide along the ic ...

Elsevier BV2012

Understanding the influence of bubble foams on magma permeability and strength is critical to investigations of volcanic eruption mechanisms. Increasing foam porosity decreases strength, enhancing the probability of an eruption. However, higher porosities ...

Nature Publishing Group2012

The description of rapid climatic changes during the last glacial period at high northern latitudes has been largely documented through Greenland ice cores that are unique climatic and environmental records. However, Greenland ice isotopic records are bias ...

A 70 ka record of explosive eruptions from the TALDICE ice core (Talos Dome, East Antarctic plateau)

Jérôme Chappellaz

The European Project for Ice Coring in Antarctica Dome ice core from Dome C (EDC) has allowed for the reconstruction of atmospheric CO2 concentrations for the last 800,000-years. Here we revisit the oldest part of the EDC CO2 record using different air ext ...

American Geophysical Union (AGU)2010

The climate of the last glacial Marine Isotopic Stage 3 (MIS3) period is characterized by strong millennial-scale variability with a succession of Dansgaard-Oeschger events first identified in Greenland ice cores and associated with variations of the Atlan ...

Elsevier BV2010

We undertook an interlaboratory comparison of techniques used to extract and analyze trapped gases in ice cores. The intercomparison included analyses of standard reference gases and samples of ice from the Greenland Ice Sheet Project 2 (GISP2) site. Conce ...

Atmospheric nitrous oxide during the last 140,000years

Jérôme Chappellaz

Typical rapid climate events punctuating the last glacial period in Greenland, Europe and Antarctica are compared to two rapid events occurring under warmer conditions: (i) Dansgaard-Oeschger event 25, the first abrupt warming occurring during last glacial ...

Millennial-scale variability during the last glacial: The ice core record

Jérôme Chappellaz

Water isotope records from the EPICA Dronning Maud Land (EDML) and the NorthGRIP ice cores have revealed a one to one coupling between Antarctic Isotope Maxima (AIM) and Greenland Dansgaard-Oeschger (DO) events back to 50 kyr. In order to explore if this n ...

Elsevier BV2010

Millennial and sub-millennial scale climatic variations recorded in polar ice cores over the last glacial period

Jérôme Chappellaz

Since its discovery in Greenland ice cores, the millennial scale climatic variability of the last glacial period has been increasingly documented at all latitudes with studies focusing mainly on Marine Isotopic Stage 3 (MIS 3; 28-60 thousand of years befor ...
