White was not involved in retrieving the ice core. But he said the ice has the potential to yield a great deal of information “about the fundamental dynamics of climate change on our planet, and ...
The team, with members from 12 European scientific institutions, drilled and retrieved a 9,186-foot-long (2,800-meter) ice core from the Antarctic ice sheet. The sample extended so deep that ...
The study, conducted under ONA head Andrew Marshall, modeled its prospective climate change on the 8.2 kiloyear event, precisely because it was the middle alternative between the Younger Dryas and the milder Little Ice Age. [29]
A portion of the core. Studies of nuclear isotopes and various atmospheric constituents provide detailed records of climate change over 100,000 years. From the analysis of the oxygen isotope ratio of the GRIP core excavated in 1992, it became clear that abrupt climate change occurred in Greenland during the last glacial period.
Ice core sample taken from drill. An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier.Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years.
The post is wrong about Arctic sea ice and climate change. On Dec. 21, 2024, the Antarctic sea ice extent was higher than on Dec. 21, 2016, but the Arctic sea ice extent was lower on that date in ...
The EPICA and Vostok cores compared. This site (, 3233 m above sea level, 560 km from Vostok Station) was chosen to obtain the longest undisturbed chronicle of environmental change, in order to characterise climate variability over several glacial cycles, and to study potential climate forcings and their relationship to events in other regions
The ice core was transported to the National Ice Core Laboratory in Denver, Colorado where it was sampled and portions were distributed to 33 institutions for analysis. The analysis included the physical, chemical and isotopic properties of the gases trapped in the ice, the soluble and insoluble material in the melted ice, and the water from ...
