The dataset summarizes various in-situ measurements collected during the ARA16A cruise, which include optical properties of the ocean surface, physical properties of sea ice cores, and aerial photographs of sea ice taken from helicopter.
KOPRI and AWI jointly conducted a radiosonde campaign at Ny-Ålesund, increasing the balloon launch frequency from once to twice daily for about one month during early winter in the period 2023–2025. The purpose of this campaign was to carry out an Observing System Experiment (OSE) to investigate how enhanced upper-level atmospheric observations in early winter over the Barents Sea region—where Arctic sea ice has undergone significant melt during the cold season—affect weather forecasting and subseasonal-to-seasonal (S2S) prediction performance in downstream regions of Eurasia.
Wind Doppler Lidar was operated during the first leg of the IBRV Araon's Arctic research expedition at the center of 4 Deck of the vessel. This instrument continuously collected vertical profiles of three-dimensional boundary layer winds (u, v, w) at every second. The installed environment on the vessel limits its operation in the near vertical PPI mode (80~90 degrees).
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.

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.
The tidal observation equipment at the King Sejong Station in Antarctica was installed by the Korea Hydrographic and Oceanographic Agency in December 2019. The equipment measures tidal waves at 1-minute intervals by measuring changes in water pressure according to sea level height in harsh Antarctic environments such as sea ice.
