Summary: The melting of permafrost in the Arctic is reshaping landscapes and threatening infrastructure, cultural sites, and natural resources. This process also impacts the delivery of organic carbon to Arctic nearshore environments, which in turn affects coastal processes, food webs, and marine resources. Future increases in runoff and permafrost thaw may further alter carbon turnover rates and OC distributions, potentially impacting coastal carbon budgets and ecosystem structure.

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: Regular monitoring of coastal areas is crucial for mitigating erosive disasters. The erosion along Ghana's coastline, like other countries in the Gulf of Guinea, is a persistent issue. This study used multiple data collection methods, including drones, cameras, satellite images, and a dumpy level, to assess shoreline changes in Elmina Bay, Ghana. The results identified the causes and areas of erosion at a fine scale and highlighted the effectiveness of local video cameras and drones for monitoring shoreline changes. Satellite imagery, although a potential alternative, has limitations in temporal resolution for detecting daily or event-based beach changes.

Summary: Approximately 11 million people, or 17% of the population, in Thailand live along the coast, facing issues such as coastal erosion, sea level rise, and land subsidence. Thailand has invested in restoration and protection efforts for coastal mangroves and beaches. This study utilized the Coastsat toolkit to digitize shoreline positions from satellite images taken between 1990 and 2019 along 560 km of coastline in Krabi and Nakhon Si Thammarat provinces. The analysis revealed varying rates of shoreline change, suggesting a linkage between extreme weather conditions and coastal erosion in Nakhon Si Thammarat, while the linkage was less clear in Krabi. The CoastSat tool provides crucial and accurate shoreline data for coastal managers and researchers, especially during travel restrictions caused by COVID-19.

Summary: Currently, coastal territories worldwide are experiencing erosion due to both natural and anthropogenic factors. This issue is particularly relevant in the Mediterranean region, including the Calabria region in southern Italy. This study focuses on the Gallico fiumara as a case study affected by hydraulic regulations and investigates the effects of engineering control measures on shoreline changes. The results show that the check dam system has influenced shoreline evolution, especially in the lower part of the watershed. The study suggests considering the conversion or removal of check dams in areas closest to the coast where engineering control has already reduced the natural riverbed slope.

Summary: Mercury in the Arctic primarily originates from emissions at lower latitudes and is related to polycyclic aromatic hydrocarbons (PAHs) in sediments. This study examined the contamination gradient of mercury from a land-based coal mine, finding higher concentrations at the mine compared to reference sites. While a clear correlation was found between Hg and PAH concentrations in sediment, marine biota were less suitable for tracing the exposure radius of the local land-based Hg source due to low contamination levels and variable PAH profiles. Close monitoring of changes in input of PAHs and Hg from land-based sources to the marine system is necessary in the warming Arctic.

Summary: Alkalinity generation from rock weathering has a significant impact on Earth's climate on geological time scales. This study finds that erosion rate plays a crucial role in determining riverine alkalinity, along with carbonate proportion, mean annual temperature, catchment area, and soil regolith thickness. Climate warming will significantly alter the weathering flux to the ocean by 2100, with the potential for a strengthening or weakening effect on the oceanic CO2 buffer, depending on emissions scenarios.

Summary: Arctic coasts are facing increasing erosion and flooding due to decreasing sea ice, thawing permafrost, and rising sea levels. This review examines the changes in Arctic coastal morphodynamics and discusses their broader impacts on Arctic systems. Climate change has a significant impact on Arctic coasts, including the loss of permafrost, sea ice, and glaciers, as well as rising sea levels. However, assessing the influence of anthropogenic warming on Arctic coastal dynamics is challenging due to limited availability of data. Despite this challenge, understanding these changes is critical as the majority of permafrost coasts are erosive, and erosion and flooding are projected to intensify.
