EXTRACTION OF ICE SHEET LAYERS FROM TWO INTERSECTED RADAR ECHOGRAMS NEAR NEEM ICE CORE IN GREENLAND
Cryosphere Ice sheet layering Radar echo sounding Sub-glacial ice flow NASA IceBridge
2016/11/23
Accumulation of snow and ice over time result in ice sheet layers. These can be remotely sensed where there is a contrast in electromagnetic properties, which reflect variations of the ice density, ac...
Location of a new ice core site at Talos Dome (East Antarctica)
radio echo sounding radio glaciology ice thickness measurements internal layering
2015/9/8
In the frame of glaciology and palaeoclimate research, Talos Dome (72°48lS; 159°06lE), an ice dome on the East Antarctic plateau, represents the new selected site for a new deep ice core drilling. The...

Scientists deep ice core at the South Pole
2015/3/4
This winter, when many people’s imaginations were fixed on the North Pole, a small group of scientists has been working on the other side of the planet. In round-the-clock daylight and frigid temperat...
Rewriting the history of volcanic forcing during the past 2000 years A year-by-year record of volcanic eruptions from a comprehensive Antarctic ice core array（图）
The desert The South Pole. The volcano. Climate change Sulfur dioxide Sulfate Ice cores
2014/7/18
RENO – A team of scientists led by Michael Sigl and Joe McConnell of Nevada’s Desert Research Institute (DRI) have completed the most accurate and precise reconstruction to date of historic volcanic s...
Volcanic eruptions recorded in the Illimani ice core（Bolivia）：1918–1998 and Tambora periods
Volcanic eruptions Illimani ice core Tambora periods
2009/3/11
Acid layers of volcanic origin detected in polar snow and ice layers are commonly used to document past volcanic activity on a global scale or, conversely, to date polar ice cores. Although most catac...
Trace elements in South America aerosol during 20th century inferred from a Nevado Illimani ice core, Eastern Bolivian Andes（6350 m asl）
Trace elements South America aerosol Nevado Illimani ice core Eastern Bolivian Andes
2009/3/11
A 137 m ice core drilled in 1999 from Eastern Bolivian Andes at the summit of Nevado Illimani (16º 37' S, 67º 46' W, 6350 m asl) was analyzed at high temporal resolution, allowing a characte...
Radiocarbon analysis in an Alpine ice core: record of anthropogenic and biogenic contributions to carbonaceous aerosols in the past（1650–1940）
Radiocarbon analysis Alpine ice core anthropogenic and biogenic contributions carbonaceous aerosols
2009/1/21
Long-term concentration records of carbonaceous particles (CP) are of increasing interest in climate research due to their not yet completely understood effects on climate. Nevertheless, only poor dat...
The transport history of two Saharan dust events archived in an Alpine ice core
transport history Saharan dust event Alpine ice core
2009/1/4
Mineral dust from the Saharan desert can be transported across the Mediterranean towards the Alpine region several times a year. When coinciding with snowfall, the dust can be deposited on Alpine glac...
Constraints on N2O budget changes since pre-industrial time from new firn air and ice core isotope measurements
N2O budget changes pre-industrial time new firn air ice core isotope measurements
2008/12/31
A historical record of changes in the N2O isotope composition is important for a better understanding of the global N2O atmospheric budget. Here we have combined measurements of trapped gases in the f...
Ice thinning, upstream advection, and non-climatic biases for the upper 89% of the EDML ice core from a nested model of the Antarctic ice sheet
upstream advection EDML ice core Antarctic ice sheet
2008/11/7
A nested ice flow model was developed for eastern Dronning Maud Land to assist with the dating and interpretation of the EDML deep ice core. The model consists of a high-resolution higher-order ice dy...
Anomalous flow below 2700 m in the EPICA Dome C ice core detected using δ18O of atmospheric oxygen measurements
EPICA Dome C ice core atmospheric oxygen
2008/11/6
While there are no indications of mixing back to 800 000 years in the EPICA Dome C ice core record, comparison with marine sediment records shows significant differences in the timing and duration of...
To interpret new high resolution climate records it becomes more and more important to know about the succession of climate events. Such knowledge is hard to get especially when dealing with different...
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 ED...
“EDML1”：a chronology for the EPICA deep ice core from Dronning Maud Land, Antarctica, over the last 150 000 years
EPICA Dronning Maud Land Antarctica
2008/11/5
A chronology called EDML1 has been developed for the EPICA ice core from Dronning Maud Land (EDML). EDML1 is closely interlinked with EDC3, the new chronology for the EPICA ice core from Dome-C (EDC) ...
