A 40 m ice core was drilled on the Tsambagarav glacier in the Mongolian Altai in 2008. After pretreatment of the ice core at the KOPRI lab including ice melting, the ice melt samples were analyzed for water isotopes (δ18O and δD) using Wavelength-Scanned Cavity Ring Down Spectroscopy (Picarro, Canada). Stable water isotope composition is used as fundamental data for depth-to-age conversion in an ice core. It can also provide valuable information on water vapor source for the sampling site.
This dataset consists of high-precision GNSS observation data collected from January to May 2025 at King Sejong Station, King George Island, Antarctica. The data can be used for monitoring crustal movements, surface stability, and glacial displacement in polar geophysical research.
This dataset presents a new catalogue of active subglacial lakes beneath Thwaites Glacier, West Antarctica, identified using CryoSat-2 satellite radar altimetry. It details the boundaries, areas, and elevation changes of each lake, complete with 95% confidence intervals. The dataset also contains estimates of ice speed changes in the TG's grounding zone.

Seismic surveys were conducted over the southwestern continental slope of the Chukchi Rise, where physical gas hydrate samples have been recovered, and over adjacent seamount structures. The objective was to characterize the subsurface geological structures and to confirm the distribution of gas hydrates in the study area. To enable reliable interpretation of the seismic sections, data processing included noise attenuation and trace balancing. Strong vertical noise generated during ice-breaking operations and ice-avoidance maneuvering was suppressed. In addition, balancing procedures were applied to reduce interpretation uncertainty caused by lateral discontinuities and amplitude variations along the profiles.
