Summary: The study reveals that a mid-Holocene sea-level highstand and subsequent sea-level fall occurred on the southwest coast of the Arabian-Persian Gulf, possibly due to the Earth crustal response to meltwater load. Analysis and modeling of sea-level indicators indicate that the highstand occurred 6.7-6.0 ka, followed by shoreline migration in line with the sea-level fall until around 3 ka.

Summary: Analyzing nearly 30 years of satellite altimetry data reveals distinct seasonal and long-term trends in sea level in the Arabian Gulf, which are opposite to changes observed in the adjacent Red Sea. Projections suggest a continued rise in sea level in the region, with potential implications for coastlines and coastal areas.

Summary: By dating coastal sediments from different tectonic zones of the Arabian Peninsula, it was found that there have been complex sea level fluctuations since the mid-Holocene. These findings are crucial for understanding future flood risks and the impacts of climate change on the Arabian coastline.

Summary: Constructing geocellular models of carbonate rocks is challenging due to the unpredictable distribution of rock properties and strong influence of diagenetic processes. This study successfully created a geocellular model using integrated sedimentological, petrophysical, diagenetic, and structural information, demonstrating a workflow for accurately representing flow controlling facies and diagenetically altered poroperm and fracture networks.

Summary: The Arabian Gulf is one of the world's most unique and fragile marine ecosystems, vulnerable to climate change due to its shallow depth and arid location. This study analyzes sea surface temperature (SST) variability in the Gulf using empirical orthogonal function (EOF) decomposition analysis from 1982 to 2020. The results indicate that SST variability in the Gulf is influenced by the El Niño-Southern Oscillation (ENSO), Atlantic Multi-decadal Oscillation (AMO), and Indian Ocean Dipole (IOD) climate modes. Additionally, the study reveals a warming trend in the average SST in the Gulf over the past four decades, despite indications of overall heat loss at the air-sea interface.

Summary: The most abundant coccolithophore species found in the eastern Arabian Sea is Gephyrocapsa oceanica, which showed malformation in low pH waters during the Southwest Monsoon. Satellite data indicates a high abundance of coccolithophores in recent years, especially during warm El Nino years. This highlights the need for a better understanding of the fate of coccolithophores in high-CO2 and warmer oceans.

Summary: The northern-eastern Arabian Sea is strongly influenced by land-ocean-climate interactions. It supplies large amounts of dissolved and particulate materials and nutrients through eolian and fluvial supply, which play important roles in biogeochemical processes. This study reconstructs past surface water Nd isotope composition and sediment provenance using eNd and geochemical records, revealing the significant influence of eolian over fluvial inputs during the mid-Holocene and its implications for nutrient supply and biogeochemical processes in the Arabian Sea.

Summary: This study was conducted in Phuket, which contributes 15% of the nation's GDP from tourism industry. Shoreline changes in beach areas were analyzed using the CoastSat open-source software and satellite imagery API. Future shoreline recession was projected based on field observation data and sea level rise scenarios. The study found mild erosion in eight locations from 2013 to 2021, with average shoreline change ranging from -4.10 to 5.47 m/year. The projection also indicated possible complete loss of 20 and 32 beaches under SSP1 2.6 and SSP5 8.5, respectively. Human activities such as coastal urbanization and development of structures along the coast were found to influence beach morphology. The study discusses the effectiveness of current coastal protection structures and proposes future management strategies.

Summary: Beach ridges are important in studying past sea-level variations and sediment dynamics in the Gulf of Thailand, but systematic studies on them are lacking. Satellite images show the presence of beach ridges in the Chanthaburi Province, divided into landward ridges and seaward ridges separated by an estuary. Luminescence dating indicates that the landward ridges formed around 3500 years ago, while the seaward ridges formed between 2100-1200 years ago, including the modern active beach.

Summary: The intensive land-sea interactions and brilliant Neolithic Cultures in the South Hangzhou Bay of eastern China have been shaped by the Holocene geomorphological evolution inherited from the Late Pleistocene. The coastal progradation and formation of estuaries played a crucial role in facilitating the settlement of foragers and the development of Neolithic cultures in the region. The diverse geomorphological processes, modulated by sea-level changes, sediment input, and local topography, have influenced the gradual transition from hunting-gathering to rice farming in the Neolithic period.

Summary: A new relative sea level curve for the Holocene Gulf of Aqaba is presented based on U-Th ages of corals. The study suggests a coeval rise of sea levels in the Indo-Pacific oceans during the early to mid-Holocene, likely due to ice melting.

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: The nations on the Arabian/Persian Gulf are the largest users of desalination technologies, but concerns have been raised about the long-term effects of increased salinity on marine ecosystems. Current desalinated freshwater production is relatively small, but projections suggest it could reach 10% of net evaporation by the end of the century. However, climate scenarios indicate that increased air temperature and potential changes in precipitation could mitigate the effects of desalination. Additionally, the circulation of high-salinity waters through the Strait of Hormuz limits basin-wide salinity increases.

Summary: This study provides detailed descriptions of intertidal pools and their thrombolite and stromatolite structures in Abu Dhabi, suggesting a model for their formation and evolution. Erosion of laminated microbial mats initiated the development of pools, which were subsequently colonized by cyanobacteria leading to the formation of stromatolites and thrombolites. The model highlights the interplay of erosion, abiotic lithification, and microbial processes in the formation of microbialites.

Summary: The Middle Ordovician phosphatic ironstone in the Welsh Basin provides new insights into the significance of ironstone and Ordovician ocean chemistry. Deposition occurred in a back-arc basin with storm-dominated shelf and coastal upwelling, creating various lithofacies associations. Large Fe grains with carbonate fluorapatite, hematite, and chamosite layers record changes in pore water E-h related to upwelling intensity and storm reworking. This study supports a model for Ordovician ironstone deposition and its impact on paleoenvironments during the Great Ordovician Biodiversification Event.

Summary: Different pathways of precipitation and diagenetic replacement can lead to similar carbonate fabrics. It is important to distinguish the underlying mechanisms for a given carbonate fabric for both environmental and diagenetic interpretations. The study of botryoidal and spherulitic aragonite associated with microbial mats reveals two distinct formation mechanisms, highlighting the relevance of these structures in paleoenvironmental interpretations.
