Summary: The study suggests that the North American and Eurasian Ice Sheets were the primary contributors to the rapid global sea-level rise event, Meltwater Pulse 1A, during the last deglaciation. The results based on sea-level constraints align with field-based ice-sheet reconstructions, supporting the idea that the freshwater causing the sea-level rise mainly came from North America and Eurasia.

Summary: This study investigates uplift variation and sea-level changes in Barbados, and shows that abrupt mass unloading caused a change in uplift rate. The reconstructed sea-level curve reveals jumps and stagnation periods. The findings are of significance for understanding past climate changes and sea-level variations.

Summary: Ice mass and sea-level changes induce glacial isostatic adjustment (GIA) at different timescales. The solid Earth is usually treated as a Maxwell viscoelastic solid for long-term GIA predictions and as an elastic solid for short-term events. However, experimental results suggest that transient deformation occurs at intermediate timescales, which cannot be captured by existing models. By using experimentally constrained viscoelastic models, this study explores transient deformation in GIA and sea-level change predictions, specifically focusing on Meltwater Pulse 1A (MWP-1A). The results reveal significant deviations from the Maxwell model and emphasize the need to revisit the source of MWP-1A and similar events.

Summary: The geological structure and post-glacial coastal evolution history of Babitonga Bay in Santa Catarina, Brazil were studied, revealing two distinct incised valleys formed at different geological periods, and the formation and development of the valleys were confirmed through relevant stratigraphic and seismic-stratigraphic research. With the rise and fall of sea level, coastal lagoons and sandy spits appeared in the bay, and the sedimentary environment in the estuarine mouth constantly changed. This study broadens our understanding of the response of similar estuary/coastal sedimentary system environments to sea level changes.

Summary: By creating a paleogeographic map and analyzing whole-genome sequencing data, this study investigates the impact of sea-level rise on human demography in Southeast and South Asia. The results show that sea-level rise reduced land area and led to the segregation of local populations. Population pressure driven by rapid sea-level rises forced the migration of Malaysian Negritos into South Asia. This research provides the earliest documented evidence of forced human migration caused by sea-level rise.

Summary: Forecasting biogeomorphological conditions for barrier islands is crucial for sea-level rise planning. This study combined probabilistic models to predict the changes and implications of sea-level rise on Fire Island, New York. The results showed that Fire Island may become flatter, narrower, and more prone to storm overwash. Beach ecosystems would dynamically respond to sea-level rise and migrate with the shoreline, while marshes would experience the most significant loss in area. However, storms could potentially create suitable conditions for nesting piping plovers, despite slight declines in their habitat due to shoreline change.

Summary: The study investigates the Holocene coral reef development in the northern South China Sea through a drill core, showing that the reef initiated around 7800 years BP and stopped vertical accretion at 3900 years BP due to sea level changes. The research suggests a rapid rise in relative sea level in the region between 7800 and 6000 years BP, followed by a slower rise and stabilization around 2 meters above the present mean sea level by 3900 years BP.

Summary: Coastal beach ecosystems are important habitats for many species, but they are vulnerable to sea level rise. Our study suggests that using simultaneously collected land cover and elevation data can provide more accurate predictions of the impact of sea level rise on beach habitats.

Summary: GIA-corrected sealevel data from the western Baltic Sea show a rapid 18 m rise in relative sea-level during the first phase of the Littorina transgression, with a rise rate of 31.5 mm/year in the time period of 8.57 to 8.0 ka BP. The relative sea-level rose from 28 m below the mean relative sea level to 10 m below it in less than 600 years. This phase documents the last major meltwater pulse resulting from the decay of the Laurentide ice sheet and additional meltwater sources from Antarctica.

Summary: Barrier islands are naturally low-lying features that can retreat upslope in response to sea level rise, but not necessarily at a constant rate. Long-term retreat occurs through a punctuated motion comprising steady retreat alternating with accelerated steps. This complex behavior is driven by cycles between two morphologies, with periodic overwash playing a key role in the barrier island's behavior during a transgression.

Summary: Geomorphic features from the southern Red Sea coasts provide valuable indicators of past sea-level change, with water loading being the primary factor influencing the spatial and temporal variability of the mid-Holocene highstand. Sea-level indicators from two locations on the As-Salif Peninsula suggest a mid-Holocene highstand of -0.5-1 m above present mean sea level.

Summary: This study compiles and analyzes 1099 Holocene relative shore-level indicators around the Baltic Sea, with a focus on data points related to the last marine stage. Results show that regions with negative RSL tendencies dominate, while transitional regions exhibit shifts from positive to negative tendencies in the mid-Holocene. Comparisons with GIA predictions highlight the need for improvements in ice-sheet and Earth-structure models, demonstrating the potential benefits of this new compilation for future studies.

Summary: In this study, water level-related depositional profiles around the Selin Co basin from the central Tibetan Plateau were investigated using luminescence dating techniques, providing insights into the Holocene history of lake-level fluctuations. The results showed a stable highstand between 10 ka and 7 ka, followed by a significant lake-level decline, potentially influenced by changes in Indian summer monsoon intensity. The study highlights the importance of meltwater input from glaciers and permafrost in driving Holocene high lake levels, particularly during warm periods on millennial timescales.

Summary: In this study, a multi-decadal record of polynya area at Pine Island Glacier (PIG) was generated using satellite imagery. The results showed significant interannual variability in polynya area, with the largest polynya occurring at the western edge of PIG just before a large iceberg calved. This suggests that polynya size and position may influence iceberg calving.

Summary: This study investigates the sedimentary sequences in estuaries in north west Nelson region of central New Zealand to determine the timing of the end of the Post Glacial Marine Transgression. The study reveals that the Parapara Inlet infilled due to lateral flood tide, fluvial delta progradation, and central basin infill at a consistent rate during the mid to late Holocene periods. Similarities in sea level curves for the end of the post glacial marine transgression at stable sites in northern New Zealand suggest a true eustatic signal for the New Zealand archipelago.

Summary: This study examines the impact of antecedent substrate on barrier island migration in response to rising sea levels. The results show that the slope of antecedent substrate plays a central role in barrier morphodynamic behavior, influencing migration rates and overwash fluxes. The study also explores future responses of specific barrier islands to varying rates of sea-level rise.

Summary: Coastal cliff erosion rates are influenced by sediment cover and storm events, with retreat rates varying spatially and temporally. Short-term erosion rates are affected by sediment cover on the shore platform, while the time scale for a return to a smooth shoreline following a storm event is approximately 24 years.

Summary: Barrier coasts, including barrier islands and beach-ridge plains, exhibit diverse morphologies over multi-decadal scales, with modern sea-level rise and sediment availability playing critical roles in shaping their evolution. This study explores the quantitative thresholds controlling barrier system behavior, revealing that subtle changes in sediment fluxes could significantly impact barrier morphology. The research suggests that the balance between relative sea-level rise and sediment flux largely determines the transitions between different barrier states, highlighting the importance of understanding these dynamics in the face of rising sea levels.
