This data set includes CO2 and CH4 records derived from three ice cores obtained at Law Dome, East Antarctica, from 1987 to 1993. Law Dome is a medium size, approximately circular, (200 km dia., 1390 ...

This data set presents centrifuge modeling of ground freeze and thaw processes. Its primary relevance is to geotechnical/civil engineering, with application to heave, thaw consolidation, and heave ...

This data set contains ice core chemistry, timescale, isotope, and temperature data analyzed by several investigators. In January 1998, the collaborative ice-drilling project between Russia, the ...

Arctic sea ice has likely reached its maximum extent for the year, at 14.33 million square kilometers (5.53 million square ...

Arctic sea ice extent appears to have reached its annual maximum on March 22, 2025. This is the lowest maximum in the 47-year ...

This data set consists of microparticle and chemistry data from Byrd Ice Core, the first ice core to reach bedrock in Antarctica. The core was drilled with a cable-suspended electromechanical rotary ...

This data set compares global atmospheric concentration of methane from ice cores taken on the ice sheets of Antarctica and Greenland. The data come from multiple ice cores on each continent, ...

As a condition of using these data, you must cite the use of this data set. Such a practice gives credit to data set producers and advances principles of transparency and reproducibility. Other ...

The global GFDL SPEAR large ensemble climate change simulations were produced by a 30-member ensemble over the period of 1921-2100. The SPEAR climate model was run using historical radiative forcing ...
