Minimal size of a barchan dune

, 2007
Barchans are dunes of high mobility which have a crescent shape and propagate under conditions of unidirectional wind. However, sand dunes only appear above a critical size, which scales with the saturation distance of the sand flux [P. Hersen, S. Douady,

Improving seed‐based restoration in Eelgrass (Zostera marina) in combined aquarium and field experiments

Restoration Ecology, EarlyView.
Abstract Introduction Seagrass restoration efforts are being implemented globally to accelerate the slow natural recolonization success. Among the various existing methods, seed‐based approaches offer the greatest scalability for species like Zostera marina, yet these methods remain undeveloped for a number of sub‐tidal systems like the Baltic Sea ...

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

Sedimentology, EarlyView.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

Morphological Response of Coastal Dunes to Typhoons and Winter Monsoons on Pingtan Island, China

Journal of Marine Science and Engineering
Wind plays a crucial role in the formation of coastal dunes, and in China, these dunes are shaped by the combined effects of typhoons and winter monsoons. However, the unique characteristics of Chinese coastal dunes impacted by these forces remain poorly

Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, EarlyView.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Reducing the impact of wave attack: dunes as natural buffers [PDF]

Coastal dune systems, with their self-regenerating capacity after storm erosion, represent natural defense zones against flooding of the hinterland. Condition: the total dune volume exceeds a certain minimum value related to the safety standard. As such,
