Summary: This study investigates the morphologic response of the Alaskan Beaufort Shelf (ABS) to increasing wave energy and suggests that coastal changes in response to the growing Arctic wave climate may be dependent on shelf morphology and even mitigated in some regions by morphologic adjustment.

Summary: The study found that an abrupt shift to well-oxygenated oligotrophic conditions led to a collapse of primary productivity in the epicontinental sea ecosystem during the CTBE. This phenomenon was likely associated with anomalous nutrient cycling in Earth's oceans, resulting in significant loss of biologically reactive nitrogen.

Summary: This study explores the geomorphological expression and geological context of a normal fault scarp in a stable continental region and provides improved estimates of its displacement, length, and other aspects. Understanding this feature is of international interest due to the rarity of large normal faulting events in stable continental regions. The analysis is based on a high-resolution digital elevation model and sheds light on the origin and relationship to the regional geology of the fault scarp.

Summary: The study explores the role of biogeochemical sulfur cycling during the Eocene-Oligocene transition, reporting a decline in seawater sulfate isotope values. Quantitative modeling suggests a significant reoxidation of sulfide from shelf sediments, affecting marine pH and alkalinity. The numbers are similar in magnitude to those observed during Pleistocene glaciations.

Summary: This study presents a geomorphological characterization of the Vacacai River Hydrographic Basin based on different scales of analysis and cartographic products. The classification is based on Ross's methodology with adaptations and automation of cartographic products, resulting in 4 levels of analysis. The results show predominance of sedimentary structures in the Peripheral Depression, morpho sculptures in the Jacui River Depression, and smooth hills in sedimentary areas. The methodology proved to be efficient and can be used for spatial organization actions.

Summary: As one of the foremost global forcings, tidal circulation exerts a pervasive influence on biological and physical processes in the world's oceans. This research identified an 18.6-year periodic variation in the lunar orbital plane and its potential ecological implications. The study used satellite data and numerical modeling to demonstrate the influence of the 18.6-year nodal lunar cycle on diurnal tidal currents in the coastal regions of the Northwest Atlantic shelf.

Summary: Mud depocenters (MDCs) are major sinks for fine-grained terrigenous material, carbon, and contaminants on modern continental shelves. Several physical processes control MDC development, including bottom transport of suspended mud, interaction with density gradients, and resuspension and dispersal by internal waves. Three conceptual paradigms for MDC development have been identified, with case studies often emphasizing processes associated with one of the paradigms.

Summary: The projected sea level rise in the China Seas for the 21st century is expected to be similar to the global average, with mass contributions being the main factor driving the increase. Local steric adjustments play a minor role in the projected sea level rise.

Summary: Seascape mapping is crucial for understanding and managing areas with economic potential. Ethnomapping can complement marine cartography by incorporating local knowledge. An integration of artisanal fishermen's knowledge with scientific data validated the mapping process and highlighted the importance of local participation in coastal conservation and management activities.

Summary: By studying the fault geometry and dynamics of the M15 block in the Andaman Sea using 3D seismic data, we have identified the presence of eight sequence interfaces, large scale extensional strike-slip faults, and normal faults. The F1 and F2 faults, which control the regional structure, are influenced by the collision between the Indian plate and the Eurasian plate. The analysis of fault development history suggests that the Miocene is a significant period for plate collision enhancement and fault generation.

Summary: The morphology of divergent continental margins is shaped by rift processes, the interaction of oceanic, continental, and transitional crust, and sedimentary processes. Classifying margin components into shelf, slope, rise, and abyssal plain segments can be challenging due to complex geomorphologies. This study aims to develop a methodology to better identify and understand the rise component.

Summary: This study investigates the effects of wave and tidal interactions on sediment resuspension and transport on continental shelves, finding that wave-tide interactions dominate in most areas under energetic conditions. The interactions between waves and tides significantly affect sediment transport modes and seabed morphology in wave-dominated or tide-dominated regions.

Summary: In this study, the offshore Egadi Islands in Italy were analyzed using high-resolution bathymetric, seismo-acoustic, and sedimentological data to map their physiography, geomorphological features, and sedimentary bedforms. The study area has a wide continental shelf separated by a linear incision called the Marettimo Channel, with erosional and depositional features identified and mapped along it. Sedimentary prograding wedges were detected on the shelf margin, indicating sea-level fall and lowstand stages during the last glacio-eustatic cycle. Various types of sedimentary bedforms were found across the continental shelf, indicating a high hydrodynamic regime. Erosive and depositional features related to bottom currents were also identified in the Marettimo Channel. These findings provide important insights into the morpho-sedimentary evolution of the Egadi Islands offshore and support the management of conservation priority habitats.

Summary: A study combining new and published pollen data from coastal wetlands in the United States found that most pollen chronohorizons were consistent with other age markers, but inconsistencies may be due to local factors such as sediment mixing or misidentification of pollen signals. Overall, using pollen chronohorizons in models led to increased precision in some cases, but also highlighted the need for careful consideration of potential inaccuracies in age-depth models.

Summary: This study investigated the sedimentation of the West Gironde Mud Patch (WGMP) on the Bay of Biscay continental shelf. Results showed that organic carbon (OC) burial rates increased seaward at most sites. Sedimentary structures indicated episodic sandy inputs at proximal sites and continuous sedimentation at seaward locations.

Summary: The study found that most wetlands in the Albemarle-Pamlico Peninsula are at risk of future inundation due to the rapid rate of sea level rise. If wetlands have room to migrate and transition from forest to marsh, the potential for sea level rise-induced loss of C and N accumulation will be 2-20%, compared to 35-88% when not accounting for wetland transitions.

Summary: On September 16, 2015, an Mw 8.3 earthquake in north-central Chile triggered a tsunami, leading to the discovery of sedimentary evidence of the 2015 tsunami and a previous one at Pachingo marsh in Tongoy Bay. The older tsunami deposit was thicker and produced by higher flow speeds and depths than the 2015 tsunami, indicating a continuing tsunami hazard in the region.

Summary: This study demonstrates the impact of hurricane season on microbial community dynamics within the barrier island system. The passage of energetic hurricanes resulted in shifts in bacterial communities but not in archaeal communities, and only in surface waters. The hurricane season also led to decreased microbial community evenness and diversity, as well as increased abundance of copiotrophic microbes. Functional genes associated with carbon and nitrogen cycling pathways were also affected by the storm season.

Summary: This study examines the long-term ecosystem impacts of a beach nourishment project conducted in 2014 on an ocean beach in North Carolina. The findings suggest that the fill sands used in the nourishment project eventually became similar in size to the native sediments, but the evidence only supports a circumstantial causation argument.
