The European Project for Ice Coring in Antarctica (EPICA) is a multinational European project for deep ice core drilling in Antarctica.Its main objective is to obtain full documentation of the climatic and atmospheric record archived in Antarctic ice by drilling and analyzing two ice cores and comparing these with their Greenland counterparts (GRIP and GISP) The EPICA (European Project for Ice Coring in Antarctica) Dome C drilling in East Antarctica has now been completed to a depth of 3260 m, at only a few meters above bedrock. Here we present the new EDC3 chronology, which is based on the use of 1) a snow accumulation and mechanical flow model, and 2) a set of independent age markers along the core. These are obtained by pattern matching of.
Die Station Dome Concordia (kurz Dome C) ist eine seit 2005 von Italien und Frankreich betriebene wissenschaftliche Forschungsstation, gelegen auf dem Eisdom Dome Charlie im Polarplateau und im Wilkesland der Ostantarktis.Sie liegt 3233 m über Meereshöhe und ist etwa 950 km von der nächsten Küste (Banzare-Küste) entfernt.Die Station liegt auf 123° östlicher Länge und 75°06' südlicher.

Epica entstand aus der Band Sahara Dust, die Mitte 2002 von Mark Jansen (Grunts, Gitarre) zusammen mit Helena Iren Michaelsen (), Ad Sluijter (Gitarre), Coen Janssen und Iwan Hendrikx gegründet wurde.Nachdem Helena Iren Michaelsen und Iwan Hendrikx die Band bereits Ende 2002 wieder verließen, stießen Simone Simons (Gesang) und Jeroen Simons (Schlagzeug) hinzu . Dans les années 1970, le site fut l'objet de nombreux prélèvements de carottes glaciaires par plusieurs géologues de diverses nationalités. Il fut appelé Dôme Charlie par les forces de secours de la marine des États-Unis en raison du code international utilisé pour la lettre C. Past Antarctic temperatures can be estimated from measurements of water stable isotopes along the EPICA Dome C ice core over the past 800 000 years. Here we focus on the reliability of the relative intensities of glacial and interglacial periods derived from the stable isotope profile. The consistency between stable isotope-derived temperature and other environmental and climatic proxies.

Two deep ice cores had been drilled within the European Project for Ice Coring in Antarctica (EPICA). The first core from Dome C reached a depth of 3260 m covering a time period of about 800,000 years. The second core from Dronning Maud Land (DML), drilled at Kohnen-Station, reached 2774 m depth with an estimated age of approximately 300,000 years. Measurements of stable isotopes (oxygen-18.

Climate models show strong links between Antarctic and global temperature both in future and in glacial climate simulations. Past Antarctic temperatures can be estimated from measurements of water stable isotopes along the EPICA Dome C ice core over the past 800 000 years. Here we focus on the reliability of the relative intensities of glacial and interglacial periods derived from the stable. The two cores drilled at the Dome C site in East Antarctica (elevation 3233 m, mean annual temperature, - 54.5 o C) in the frame of the European Program for Ice Coring in Antarctica, now provide a continuous deuterium profile covering the last 800 ky back to marine stage . Measurements have been performed on 55 cm samples with a precision of either ± 0.5 or ± 1.5 per mill depending of the. from the EPICA Dome C (EDC) ice core covering the period between 300 and 800ka (thousands of years before present). The samples stored at −25 C show clear gas loss affecting the precision and mean level of the δO2/N2 record. Two dif-ferent gas loss corrections are proposed to account for this effect, without altering the spectral properties of the original datasets. Although processes at. A detailed ionic component record was performed on EPICA Dome C ice core (East Antarctica) to a depth of 3190 m using Ion Chromatography and Fast Ion Chromatography (FIC). At depths greater than 2800 m, the sulfate profile shows intense, sharp spikes which are not expected due to the smoothing of sulfate peaks by diffusion processes. Moreover, these spikes show an anomalous chemical. E. W. Wolff1, P. C. Tzedakis2, M. Crucifix3. 1. Department of Earth Sciences, University of Cambridge, UK; 2.

EPICA Dome C 1 (EDC1), the first hole at Dome C, ended on 20 December 1998 at 783m depth when the drill was deemed irretrievably stuck after several attempts to free it. In November 1999, all surface equipment was moved 10m north from its original location. A new hole, EDC2, was started from the surface on 11 December 1999. By 31 January 2001, a depth of 1458m had been reached. Three more. Dome C, also known as Dome Circe or Dome Charlie, located at Antarctica at an altitude of 3,233 m or 10,607 ft above sea level, is one of several summits or domes of the Antarctic Ice Sheet.Dome C is located on the Antarctic Plateau, 1,100 km inland from the French research station at Dumont D'Urville, 1,100 km inland from the Australian Casey Station and 1,200 km inland from the Italian.

Temperature change (light blue) and carbon dioxide change (dark blue) measured from the EPICA Dome C ice core in Antarctica (Jouzel et al. 2007; Lüthi et al. 2008). Other paleoclimate proxies help us understand the role of the oceans in past and future climate change. The ocean contains 60 times more carbon than the atmosphere, and as expected, the changes in carbon dioxide in the atmosphere. EPICA (European Project for Ice Coring in Antarctica) ist ein Gemeinschaftsprojekt, an dem zehn europäische Länder beteiligt sind. Im Rahmen dieses Programms finden zwei Eiskerntiefbohrungen statt. Die eine an Dome C hat bereits das älteste Eis (älter als 800.000 Jahre) erbohrt. Die jetzige Bohrung an der Kohnen Station wird nicht so altes Eis erbohren, dafür aber eine bessere zeitliche. Here we present new deuterium data from the EPICA Dome C ice core, documenting at decadal resolution temperature changes occurring over the East Antarctic plateau during the warmer-than-today last interglacial. Expanding previous evidence of instabilities during the last interglacial, multicentennial subevents are identified and labeled for the first time in a past interglacial context. A.

So far, the Antarctic Vostok and EPICA Dome C ice cores have provided a composite record of atmospheric carbon dioxide levels over the past 650,000 years. Here we present results of the lowest 200 m of the Dome C ice core, extending the record of atmospheric carbon dioxide concentration by two complete glacial cycles to 800,000 yr before present. From previously published data and the present. Abstract. Ice sheets provide exceptional archives of past changes in polar climate, regional environment and global atmospheric composition. The oldest dated deep ice core drilled in Antarctica has been retrieved at EPICA Dome C (EDC), reaching ∼ 800 000 years. Obtaining an older paleoclimatic record from Antarctica is one of the greatest challenges of the ice core community NOAA Climate.gov, based on EPICA Dome C data (Lüthi, D., et al., 2008) provided by NOAA NCDC Paleoclimatology Program. Source of sensitivity estimates and their limitations. Broadly speaking, climate scientists infer sensitivity by looking at the correlation between global concentrations of carbon dioxide and global average surface temperature. They look at the correlation using modern.
Here, we investigate the older part of this interval by presenting a high-resolution record of CO 2 mole fractions covering a full glacial-interglacial cycle from 330 to 450 ka BP [i.e., marine isotope stage (MIS) 9e to MIS 12a ], measured on samples from the European Project for Ice Coring in Antarctica (EPICA) Dome C (EDC) ice core using an improved dry-extraction technique 10Be evidence for the Matuyama-Brunhes geomagnetic reversal in the EPICA Dome C ice core.

Author information: (1)Centre de Spectrométrie Nucléaire et de Spectrométrie de Masse, IN2P3-CNRS-Université de Paris-Sud, Bât. 108, 91405 Orsay, France. email@example.com An ice core drilled at Dome C, Antarctica, is the oldest ice core so far. Measurements of the two water stable isotopes (dD and d 18 O) along EPICA (European Project for Ice Coring in Antarctica) Dome C ice core are combined with simple isotopic modelling (distillation models) to reconstruct the variability of both the site temperature (East Antarctica) and the moisture source temperature (nowadays probably the subantarctic Indian Ocean)
