Carbonate sedimentology: An evolved discipline
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

Polygonal tepee structures of Arabia
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Design, commissioning and performance of a device to vary the turbulence in a recirculating flume
Ambient turbulent flow structures are one of the key drivers that will determine the rate of wake recovery downstream of tidal turbines. For second and third generation arrays or farms such a parameter is critical for the determination of inter-device ...

We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation

Domed‐rim microbial polygons and their preservation potential
Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

ABSTRACT Since the 2011 Great East Japan earthquake, tsunami evacuation towers have been constructed in coastal regions based on worst‐case predictions to provide additional safety margins against unprecedented tsunamis. However, the extent to which such assumptions effectively reduce casualty risk remains unclear.
