Summary: Coastal areas are highly sensitive to sea-level change and play a crucial role in socio-economic activities. The future magnitude and rate of sea-level change are of great importance for coastal risk aversion and adaptation measures. Addressing this issue requires a transdisciplinary scientific community and close collaboration with local stakeholders.

Summary: Global sea level rise is primarily caused by heating of the ocean and the input of freshwater from melting ice. This study shows that trends in sea level rise can also be accurately tracked by observing changes in ocean salinity. The results highlight the importance of measuring ocean salinity for monitoring global sea level changes.

Summary: The design of coastal defense structures needs to consider the projected sea-level rise. Global annual maxima sea levels have been increasing primarily due to a rise in mean sea level. Non-stationary extreme value theory is applied to model sea levels with mean sea level as a covariate, showing that many locations will experience their present-day 100-year return level as a more frequent event in the future. By the end of this century, almost all locations examined will encounter their current 100-year return level on an annual basis.

Summary: The study reveals that areas most vulnerable to sea-level rise are mainly located in tropical regions, especially in tropical Asia. Even with a conservative estimate of 1 meter sea-level rise, the population in these areas is expected to increase significantly.

Summary: Global mean sea level rose by 15 mm over June 2014 - May 2016, with 80% of the rise attributed to a global ocean mass increase. The South American continent, specifically the Amazon basin, contributed significantly to this increase. These changes were influenced by two El Nino events, which affected precipitation patterns worldwide.

Summary: We provide the first global estimates of annual average exceedances of various flood levels under sea-level rise (SLR). Minor flooding will occur most days worldwide with a global SLR of 0.7 m, while moderate flooding occurs with the same frequency under 1.0 m SLR. The differences in flood thresholds, tidal ranges, and non-tidal variability among regions lead to variations in the SLR required for chronic flooding to occur. Our findings have implications for coastal flood hazard assessments and we have developed a framework called RAFFFTS to identify potential future tidal flooding hotspots using only 1-year observational records.

Summary: This study presents the first global estimates of annual average exceedances of minor, moderate, and major flood levels under sea-level rise. The findings demonstrate that chronic flooding can occur with less sea-level rise in areas with lower flood thresholds and smaller tidal ranges. The study also introduces a new assessment framework, RAFFFTS, which can identify potential future tidal flooding hotspots using only 1-year observational records.

Summary: The study utilized tide gauge data and information from tide, surge, and ocean models to calculate and validate the Gumbel scale parameters of extreme sea level distributions worldwide. Incorporating ocean model information led to significantly improved correspondence between observed and modelled scale parameters. This enhanced provision of scale parameters along the coastline allows for more complete investigations of sea level exceedance frequencies and provides coastal engineers with more reliable estimates for designing defenses to protect coastal populations.

Summary: Using GPS Imaging, we estimated rates and patterns of vertical land motion (VLM) globally. The assessment showed that the uplift and subsidence on land is mainly driven by loading from the terrestrial hydrosphere, with a global assessment of uplift and subsidence attributable to GIA and non-GIA sources.

Summary: The interaction between the ocean, cryosphere, and seafloor is vital for understanding processes such as deep ocean mixing, glacier dynamics, and sea-level rise. However, there is a critical knowledge gap in accurately mapping the seafloor in Polar regions, which needs to be addressed to improve predictions and understanding of these processes.

Summary: The Peninsular Malaysia Geodetic Vertical Datum 2000 (PMGVD2000) has deficiencies due to local datum offsets, levelling errors, land subsidence, and sea level changes. To address these issues and improve elevation assessments, a new height reference system called PMGVD2022 has been developed.

Summary: In this study, the contribution of different global geopotential models in geoid computation is examined using the remove-compute-restore approach. Gravity measurements were conducted in two test areas in Greece, and the measurements were used along with selected geopotential models to produce the reduced gravity field and derive the residual gravity field. These geoid models were validated with gravity/GNSS/leveling measurements, and the accuracy was influenced by the inclusion of non-recent data and the geopotential model used.

Summary: We provide a worst case scenario for extreme sea levels (ESLs) along the global coastline by 2100. Under these conditions, by 2100, the global coastline would experience ESLs above the global mean of 4.2 m, with some areas reaching up to 9-10 m. Future sea level rise is the main driver behind the increase in magnitude of ESLs, contributing to 90% of the increase.

Summary: The study analyzed the correspondence between land cover categories from the CLC2018 dataset and spectral information from various satellite images. Various statistical tests and classification methods were used, showing that wetlands and water bodies were prone to confusion with other categories, and Random Forest classification outperformed Linear Discriminant Analysis. PlanetScope data was found to be the most accurate.

Summary: A framework is developed in this study to classify the types of headland-bay beaches in Southeast Asia. The results show that dynamic bays are more common than stable bays. Dynamic bays are highly sensitive to low sediment supply, but become less sensitive as the sediment supply increases. The study also presents the development of sediment control and a combined method, demonstrated by a case study on stabilizing a dynamic unstable bay.
