TL;DR: Continuous chemical proxy data spanning the last eight glacial cycles from the Dome C Antarctic ice core constrain winter sea-ice extent in the Indian Ocean, Southern Ocean biogenic productivity and Patagonian climatic conditions and observe large glacial–interglacial contrasts in iron deposition, which is infer reflects strongly changing Patagonia conditions.
Journal ArticleDOI
Continuous record of microparticle concentration and size distribution in the central Greenland NGRIP ice core during the last glacial period
TL;DR: In this article, a laser microparticle detector used in conjunction with continuous sample melting has provided a more than 1500 m long record of particle concentration and size distribution of the NGRIP ice core, covering continuously the period approximately from 9.5-100 kyr before present; measurements were at 1.65 m depth resolution.
Journal ArticleDOI
DNA signature of thermophilic bacteria from the aged accretion ice of Lake Vostok, Antarctica: implications for searching for life in extreme icy environments
Sergey A. Bulat,Irina A. Alekhina,Michel Blot,Jean-Robert Petit,Martine de Angelis,Dietmar Wagenbach,Vladimir Ya. Lipenkov,Lada P. Vasilyeva,Dominika M. Wloch,Dominique Raynaud,V. V. Lukin +10 more
TL;DR: This article used 16S ribosomal genes to estimate the bacterial contents of Lake Vostok accretion ice samples at 3551 m and 3607 m, both containing sediment inclusions and formed 20000-15000 yr ago.
Journal ArticleDOI
Observations of atmospheric variability and soil exhalation rate of radon-222 at a Russian forest site Technical approach and deployment for boundary layer studies
Ingeborg Levin,Matthias Born,Matthias Cuntz,U. Langendörfer,Stefan Mantsch,Tobias Naegler,Martina Schmidt,Andrej Varlagin,Stefan Verclas,Dietmar Wagenbach +9 more
TL;DR: In this article, a monitor for continuous observations of the atmospheric 222 Rn daughter activity has been improved and successfully implemented in a field study in the European Taiga (Fyodorovskoye Forest Reserve).
Journal ArticleDOI
A seasonally resolved alpine ice core record of nitrate: Comparison with anthropogenic inventories and estimation of preindustrial emissions of NO in Europe
TL;DR: In this article, the impact of growing NO emissions on the mid-troposphere nitrate levels over Europe from 1925 to 1997 was investigated using high-resolution records from Col du Dome (CDD, 4250 m above sea level, French Alps) ice cores.
