Boreas, EarlyView.Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Boreas, EarlyView.Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

Boreas, EarlyView.Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Boreas, EarlyView.Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (

International Journal of Sediment ResearchMany fluvial systems have undergone significant changes in their morphology due to base level fall since the last glaciation. Channels in such transient fluvial systems continuously adjust their morphology and may still be incising until reaching a new ...

Boreas, EarlyView.Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Morphosedimentary dynamics of ephemeral rivers affected by gravel mining: GIS mapping and geomorphic change detection [PDF]
, 2018 Mediterranean regions have a long history of human occupation and land uses, particularly centered next to fluvial courses. Environmental pressures along rivers increased as the population increased since late XIX century. In Spain, rivers are public spaces and only recently public administrations became sensible in regard of the environmental ...

Restoration Ecology, EarlyView.Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Restoration Ecology, EarlyView.Dam removals are increasing globally, yet ecological outcomes vary widely because biological recovery depends on post‐removal connectivity and access to source populations. We evaluated how multiple dam removals and remaining fragmentation influenced fish assemblage recovery in the Cuyahoga River (OH, United States), a historically polluted Great Lakes
