The multichannel seismic survey was conducted in the Mackenzie Trough of Candian Beaufort Sea to investigate the characteristics and distribution of the gas hydrate-related BSR. In this paper, thfree final migrated seismic data (BF09, BF10 and BF12) lines were presented. The seismic velocity model by iterative migration velocity analysis (IMVA) methods and the saturation model of the gas hydrate and free gas using the effective medium theory (EMT) model were constructed. All dataset is provided to standard segy format.
Each six sequences were newly determined in this study. Molecular data from over 56 taxa of the Bangiales worldwide including previously published sequences, indicated that monophyly for the genera Bangia and Porphyra is not supported, as in previous molecular studies. Nuclear SSU rDNA, plastid rbcL and mitochondrial cox1 gene sequences were investigated for the Bangiales from the Antarctica and its adjacent waters.

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.

In order to understand the role of CDW (Circumpolar Deep Water) in controlling the hydrodynamics and related biochemical processes on the continental shelf of the Ross Sea, 4 moored lines along with CTD sensors, current profilers for the long-term observation were deployed at 4 different position in Little American Basin to entrance of continetal shelf during 2020-21 Antarctic Cruise(ANA11A). Series of salinity-conductivity probes and acoustic doppler current profilers(ADCPs) were attached to each line depending on the depth and location. Those moorings were recovered during 2022-23 Anatarcic Cruise(ANA13B) in Februery, 2023, successfully. Recovered data covered approximately 2 years period(Dec. 2020 - Feb. 2023).
