Multichannel seismic (MCS) data were acquired on the outer continental shelf of the Canadian Beaufort Sea during expeditions ARA04C (2013) and ARA05C (2014). These seismic lines are used to calculate the base of submarine permafrost based on the depth of the seismically detected base of the gas hydrate stability zone (BGHSZ). This repository contains processed MCS lines ARA04C-01,-02,-03,-05,-06,-07,-08,-09,-10,-11,-12 and ARA05C-01,-03,-04,-05,-06,-07,-08,-11,-14,-14T,-16,-16T,-17 as time-migrated sections, the interpreted picks of the BGHSZ as txt-file as well as a Matlab code used for calculating the base of permafrost from the depth of the BGHSZ. All MCS lines are available as conventional amplitude data. In addition, lines 05-03, -07 and -17 are provided as diffraction strength – the squared envelope of diffractions that were separated beforehand – with and without multiple attenuation processing applied.

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. For citation purposes, refer to the article by B-H Kim, C-K Lee*, K-W Seo, W S Lee, and J-W Park, 'New Catalogue of Thwaites Glacier Subglacial Lakes and Their Activity Revealed by CryoSat-2 Altimetry,' currently under revision for the Journal of Geophysical Research: Earth Surface.

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.
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.
