Summary: In this study, the researchers used acoustic Doppler current profilers to investigate the mechanisms of water and sediment transport in Onsan Bay. They found that water circulation in the bay was influenced by freshwater discharge from the river and exchange with the open sea, as well as by wind-induced currents. The sediment transport within the bay was mainly controlled by estuarine residual circulation, and frequent resuspension events contributed to an increase in sediment concentration. Considering the prevailing winds in the area, sedimentation is expected to persist in Onsan Bay.

Summary: This study reveals the mechanism for the movement of secondary turbidity maximum (STM) and sediment resuspension in a microtidal estuary. The strength of the residual estuarine current is influenced by a combination of factors such as tidal currents, wind, and precipitation. The study found that suspended sediments in the estuary are more influenced by the residual currents than tidal currents, creating a mobile sediment pool. When down-estuary winds are applied to the sediment pool, the sediments are readily resuspended to form a turbidity maximum. The STM moves up-estuary due to persistent high residual currents and down-estuary due to intermittent low residual currents.

Summary: This study aims to assess changes in estuarine and coastal hydrodynamics due to the construction of long jetties at the Patos Lagoon inlet in Brazil. A three-dimensional numerical model was used to evaluate hydrodynamic changes before and after the jetties construction. The presence of jetties resulted in reduced current velocities, decreased salt transport capacity, and lower salinity values in the channel, but intensified current velocities in the plume jet and increased continental water offshore. This study highlights the importance of evaluating ecological, sedimentary, and morphological aspects prior to coastal constructions and investigating past human-induced impacts for future sustainable development.

Summary: The sources and transformation of carbon in estuaries were studied using mass balance and ecosystem metabolism data. The study found that the physiographic setting of the estuaries influenced the forms and fluxes of carbon. Contrary to expectations, the highest retention of organic carbon occurred during periods of high river discharge. In summer, internal cycling of carbon was large compared to external forcing.

Summary: This study demonstrates the correlation between the strength of hydrologic sensitivity (HS) under El Nino-Southern Oscillation (ENSO) and HS in the context of climate change. The findings suggest that central Pacific ENSO events are a better predictor of HS under future warming. GCMs with greater HS exhibit a weakening of the atmospheric circulation and expansion under ENSO.

Summary: This study examined the contribution of the Pacific decadal oscillation (PDO) to the record-breaking drought in the Korean Peninsula from 2013 to 2017. The study found that the positive phase of the PDO during the mid-2010s led to a precipitation deficit, resulting in 5 years of meteorological drought. The enhanced atmospheric heating anomalies over the Pacific, caused by PDO-related sea surface temperature warming, played a key role in reducing precipitation over the Korean Peninsula.

Summary: The researchers investigated four adjacent vegetated coastal habitats in Cadiz Bay, South Spain, and found that subtidal seagrass Cymodocea nodosa had the highest organic carbon and total nitrogen stocks, followed by upper intertidal salt marsh Sporobolus maritimus, subtidal rhizophytic macroalgae Caulerpa prolifera, and lower intertidal seagrass Zostera noltei. They also observed that sedimentation and organic carbon burial rates increased with elevation. Overall, this study emphasizes the importance of using habitat-specific carbon and nitrogen stocks and burial rates to predict the sequestration capacity of vegetated coastal habitats at the seascape level.

Summary: The study reveals the transport and accumulation of mercury in the water column and abyssal sediments of the Eastern Mediterranean. Atmospheric deposition, including Saharan dust, is the main source of mercury, and lateral advection contributes to higher mercury fluxes in the mid-depth and near-bottom water layers. In the deep sediment, mercury concentrations are relatively low, but localized high concentrations are observed due to organic matter preservation. Historical accumulation rates of mercury show an increase during the late Iron Age, the Roman period, and the Industrial Era.

Summary: This study analyzed sediment from Cienfuegos Bay, Cuba to examine the occurrence of organic pollutants from 1990 to 2015. The results showed the presence of regulated contaminants such as PCBs, OCPs, and PBDEs, with a decline in PCB contamination since 2007. Emerging contaminants, including PAEs, OPEs, and aHFRs, showed sharp increases, possibly due to the growing global usage of flame retardants and plasticizer additives. Local sources, such as a plastic recycling plant and urban waste outfalls, may contribute to these trends. Further research is needed to understand the influx of these emerging contaminants.

Summary: This study examines the variability in soil organic carbon storage and burial rates in intertidal estuarine habitats of the Atlantic European coast and its relationship to biotic and abiotic drivers. The results show higher soil organic carbon stocks in high-marsh communities compared to low-marsh communities, seagrass meadows, and tidal flats. The study also found that soil organic carbon stocks and burial rates decrease from inner to outer estuarine sections, reflecting the decrease in river influence.
