Intertidal sands are global hotspots of terrestrial and marine carbon cycling with strong hydrodynamic forcing by waves and tides and high macrofaunal activity. Yet, the relative importance of hydrodynamics and macrofauna in controlling these ecosystems remains unclear. Here we compare bacterial, archaeal, and…

The intertidal sediment environment is dynamic and the biofilm bacterial community within it must constantly adjust, but an understanding of the differences in the biofilm bacterial community within sediments of different types is still relatively limited. In this study, the structure of the bacterial community in…

'Morgan Hartley' 'Matthew Holden' 'David M. Paterson' 'Maura (Gee) Geraldine Chapman'] Intertidal systems are complex and dynamic environments with many interacting factors influencing biochemical characteristics and microbial communities. One key factor are the actions of resident fauna, many of which are regarded as…

'Shan Jiang' 'Biao Chen' 'Changi Wong'] There is limited information regarding the influence of mangrove growth on the morphological evolution of intertidal mudflats. In this study, Tan Phu Dong district, Tien Giang Province, Vietnam, was selected for investigating how mangrove growth influenced the morphological…

Relationships between concentrations of Potentially Toxic Elements (PTEs) in estuarine sediments and their impact benthic invertebrate communities are poorly understood. We sampled and analysed PTEs in sediments and benthic invertebrates from five sites surrounding the Skeena Estuary, including sites adjacent to an…

Seagrass meadows are globally distributed coastal ecosystems that provide habitats for diverse species and facilitate ecosystem services, such as carbon storage and nutrient cycling. However, factors linked to human activities and climate change are causing seagrass decline worldwide, thus impacting benthic community…

In many European estuaries, extensive areas of intertidal habitats consist of bare mudflats and sandflats that harbour a very high abundance and biomass of macrobenthic invertebrates. The high stocks of macrobenthos in turn provide important food sources for the higher trophic levels such as fish and shorebirds.…

'Christine Dupuy' 'Hans J. Hartmann'] In shallow macrotidal ecosystems with large intertidal mudflats, the sediment-water coupling plays a crucial role in structuring the pelagic microbial food web functioning, since inorganic and organic matter and microbial components (viruses and microbes) of the microphytobenthic…

Sea-level rise induced by climate change may have significant impacts on the ecosystem functions and ecosystem services provided by intertidal sediment ecosystems. Accelerated sea-level rise is expected to lead to steeper beach slopes, coarser particle sizes and increased wave exposure, with consequent impacts on…

Neoichnological observations help refine paleoichnological records. The present study reports extensive observations on the distribution, morphology, occurrence and association of burrows and fecal pellets of the polychaete Nereis diversicolor in the Kundalika Estuary on the west coast of India. Our holistic study of…

using A Portable Free-Fall Penetrometer Authors: ['Md. Rejwanur Rahman' 'Adrián Rodríguez-Marek' 'Nina Stark' 'Grace M. Massey' 'Carl T. Friedrichs' 'Kelly M. Dorgan'] The geotechnical evaluation of seabed sediments is important for engineering projects and naval applications, offering valuable insights into sediment…

'Mohammadfarid Ghasemi' 'Maryam Moradi'] The Ilam Formation (Cenomanian–Santonian in age) is considered one of the main rock reservoirs of the Bangestan Group in the southwest of Iran. This formation mostly consists of carbonate rocks. To examine the sedimentary environment, diagenesis, sequence stratigraphy, and…

Fifty million cubic meters of marine sediments are dredged each year in France in order to maintain harbor activities and sustain the economy of littoral territories. Because of anthropogenic activities in and around harbors, sediments can contain significant amounts of chemical and organic pollutants whose behavior…

The effects of turbidity and sedimentation stress on early life stages of corals are poorly understood, particularly in Atlantic species. Dredging operations, beach nourishment, and other coastal construction activities can increase sedimentation and turbidity in nearby coral reef habitats and have the potential to…

Extreme weather events increasingly threaten coastal water quality, yet the mechanisms by which tropical cyclones impair microbial conditions remain poorly quantified. We develop a Large Language Model–Assisted Microbial Source Tracking (LAMST) framework to trace the origins of microbial threats—fecal indicator…

'Joseph Calantoni'] The results of Direct Numerical Simulations of the oscillatory flow over a cohesionless bed of spherical particles, mimicking sediment grains, are described. The flow around the sediment particles is explicitly computed by using the immersed boundary method, which allows the force and torque acting…

The ubiquity of microplastics in the marine environment has been highlighted in recent years, yet the extent of microplastics pollution in coastal areas, especially off the coast of Japan, remains unclear. Here we provide a comprehensive dataset of microplastic pollution in surface water and sediment around coastal…

The combined effect of tidal forcing and aquifer heterogeneity leads to intricate transport patterns in coastal aquifers that impact both on solute residence times and mixing dynamics. We study these patterns through detailed numerical simulations of densitydependent flow and transport in a three-dimensional…
