Pressure-induced transformations in LiCl-H2O at 77 K

A systematic study of the properties of high-density amorphous ice (HDA) in the presence of increasing amounts of salt is missing, especially because it is challenging to avoid ice crystallization upon cooling the pressurized liquid. In order to be able to ...

Beyond Point Measurements: Sea Ice Floes Characterized in 3-D

Katherine Colby Leonard, Ernesto Trujillo Gomez

A new methodology for coincident floe-scale measurements of the surface elevation, snow depth, and ice draft (the thickness below the water line) of Antarctic sea ice has been demonstrated during two recent research voyages: the Australian-led Sea Ice Phys ...

South Pole glacial climate reconstruction from multi-borehole laser particulate stratigraphy

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The IceCube Neutrino Observatory and its prototype, AMANDA, were built in South Pole ice, using powerful hot-water drills to cleanly bore >100 holes to depths up to 2500 m. The construction of these particle physics detectors provided a unique opportunity ...

Recent warming at Summit, Greenland: Global context and implications

Konrad Steffen

Observations at Summit, Greenland suggest that the annual mean near-surface air temperature increased at 0.090.01 degrees C/a over the 1982-2011 climatology period. This rate of warming, six times the global average, places Summit in the 99th percentile of ...

Eemian interglacial reconstructed from a Greenland folded ice core

Jérôme Chappellaz

The analysis of air bubbles trapped in polar ice has permitted the reconstruction of past atmospheric concentrations of CO2 over various timescales, and revealed that large climate changes over tens of thousands of years are generally accompanied by change ...

Measurement of South Pole ice transparency with the IceCube LED calibration system

Matthias Wolf, Shirit Cohen, Mathieu Ribordy, Xiaoxia Bai

The IceCube Neutrino Observatory, approximately 1 km(3) in size, is now complete with 86 strings deployed in the Antarctic ice. IceCube detects the Cherenkov radiation emitted by charged particles passing through or created in the ice. To realize the full ...

On the relationship between total ozone and atmospheric dynamics and chemistry at mid-latitudes - Part 2: The effects of the El Nino/Southern Oscillation, volcanic eruptions and contributions of atmospheric dynamics and chemistry to long-term total ozone changes

Anthony Christopher Davison, Linda Frossard

We present the first spatial analysis of "fingerprints" of the El Nino/Southern Oscillation (ENSO) and atmospheric aerosol load after major volcanic eruptions (El Chichon and Mt. Pinatubo) in extreme low and high (termed ELOs and EHOs, respectively) and me ...

Two-phase change in CO 2, Antarctic temperature and global climate during Termination II

Jérôme Chappellaz

Methane measurements along the Vostok ice core reveal substantial changes over the past 160,000 years which are associated with climate fluctuations. These results point to changes in sources of methane and also show that methane has probably contributed, ...
