Journal of Quaternary Science, EarlyView.ABSTRACT Submarine caves are cryptic, climatically sensitive habitats with long‐term ecological dynamics that are poorly understood. We present the first palaeoecological analysis of bryozoans from Daidokutsu Cave (Okinawa, Japan), based on a sediment core spanning approximately the last 7000 years.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology
Archaeometry, EarlyView.ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Archaeometry, EarlyView.ABSTRACT This study presents a systematically integrated, multiproxy characterisation of Iron Age ceramics from Tyre (Lebanon). Ninety‐nine ceramic samples from stratified Iron Age contexts on Tyre's Acropolis, together with a small Late Bronze Age and raw‐clay reference set, were analysed using petrography, microfossil identification, X‐ray ...

Sedimentology, EarlyView.ABSTRACT Seismic‐scale features such as deeply incised submarine valleys and mounded drifts together with ichnological features indicative of discontinuous sedimentation and erosional episodes have recently been documented from the Upper Cretaceous chalk in the southern Baltic Sea area.

Sedimentology, EarlyView.ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Seasonal data on Rose Bengal stained foraminifera in the head of Kongsfjorden, Svalbard
Data in Brief, 2019 Current ‘Atlantification’ of the Arctic Ocean affects benthic communities leading to the changes in their structure and abundance. Such areas as Svalbard that are seasonally affected by Atlantic and Arctic water masses may give a possibility to ...

Microfacies Analysis of the Reefal Limestone, Marah Formation, East Borneo, Indonesia
Iraqi Geological Journal, 2023 Miau Baru, Kongbeng in East Borneo is a relatively narrow area with complex geological features. The abundance of larger benthic foraminifera shows diversity in the carbonate succession of the Marah Formation but previously has less attention ...

Downcurrent variation in submarine channel‐fill architecture from the shelf to upper slope
Sedimentology, EarlyView.ABSTRACT The transition between the shelf and the upper slope is often considered an area of sediment bypass, where steeper gradients increase flow velocities and maintain particles in suspension. In addition to transferring sediments into deeper basins, upper‐slope areas can also host channelised submarine deposits.
