Summary: The study introduces the methodology of the UK Radionuclide National Data Centre to address the detection and source identification of radioxenon, using automated analysis of radiometric data and atmospheric transport simulations. The research estimates the detectability of radioxenon isotopes from North Korea and other selected regions, providing insights into the detection capabilities across different areas.

Summary: The origins and development of rice cultivation are crucial aspects in studying agricultural and environmental changes in East Asian prehistory. Stable isotope analysis shows that rice cultivation remained stable for around 1500 years, with rice having higher nitrogen stable isotope values than dry crops, potentially due to bacteriologic denitrification in anaerobic paddy soil.

Summary: The study on decaying post-seismic deformation on the Korean Peninsula indicates that crustal movement is gradually returning to its pre-earthquake motion, with the recovery pattern influenced by regional geologic structures and time.

Summary: Understanding subtidal coastal sea level fluctuations is crucial for sustainable coastal use. This study compared modeled phase speeds with observed propagation speeds and found them to be consistent, although there was some underestimation. The study also highlighted the impact of non-CTW origin subtidal sea level fluctuations on the model.

Summary: This study developed a regional tide-tsunami interaction model to investigate the dynamic tide-tsunami interaction and its influence on tsunami propagation and amplification. The results show that the dynamic interaction generally amplifies the water level and velocity as the tsunamis approach the coastal regions. However, due to the complexity of the topography, the impact of the dynamic interaction on water elevation and velocity is inconsistent.

Summary: This study investigated the impact of the Tohoku-Oki earthquake on South Korea using GNSS measurements. The research found that during the earthquake, there were significant displacements and deformation. After the earthquake, the South Korean Peninsula experienced extensional deformation and an effective rotational change.

Summary: The study reveals that the dynamic ground motions induced by the 2011 Tohoku-Oki megathrust earthquake in the Korean Peninsula are mainly composed of elastogravity waves and seismic waves. The large and slow dynamic ground motions of this megathrust earthquake have caused significant peak ground displacements and velocities at far-regional distances, with variations depending on source radiation pattern and continental ray paths.

Summary: By using otolith microchemistry, this study investigated the stock structure and migratory trends of Pacific cod around the Korean Peninsula, identifying two distinct stocks and supporting natal philopatry in the species. Analysis of elemental signatures revealed clear ontogenetic migration trends in the first 2 years of life.

Summary: This study examined the use of regression residual kriging method to fill the gaps in satellite sea surface temperature images, resulting in improved accuracy. By removing outliers and building a multiple linear regression model, the method was able to generate gap-filled values that closely matched the in situ measurements.

Summary: Improving estimations of long-term trends in global and regional sea level rise is crucial for climate change mitigation and adaptation. Satellite altimetry data, widely used for this purpose, often suffer from significant aliasing effects in regions with strong tidal motions unless accurately corrected using ocean tide models. Long-term trends estimated from altimetry data are also influenced by regional circulation changes and inconsistencies between satellite missions.

Summary: This study investigated the importance of aerosol optical depth for deriving clear sky irradiance in radiative transfer models and examined its viability in a universal or community model for public use. The results confirm that the clear sky model using gridded datasets of aerosol optical depth is suitable for use as a universal or community model.
