Wetlands as environments of early human occupation: A new classification for freshwater palaeowetlands

open access: yesThe Depositional Record, EarlyView.
A new classification for inland freshwater palaeowetlands to be used in the field or core laboratory by sedimentologists, providing examples from the Guadix Basin (southern Spain). Abstract Present wetlands have proven to be delicate, biodiverse ecosystems, that are natural sinks for CO2 and act as good indicators for climate changes.

Fifty years of research on the Joulters ooid sandbody—Impact on carbonate sedimentology and diagenesis and lessons learned from an invaluable analogue

open access: yesThe Depositional Record, EarlyView.
The Joulters ooid sandbody of northern Great Bahama Bank is a vast expanse of muddy ooid sands partly rimmed by clean ooid sands and formed into a relatively thick layer of significant extent. Knowledge of the development of depositional and diagenetic patterns in the Joulters example has forwarded our general understanding of carbonate sedimentology ...

Light propagation in inhomogeneous and anisotropic cosmologies [PDF]

open access: yesarXiv, 2015
The standard model of cosmology is based on the hypothesis that the Universe is spatially homogeneous and isotropic. When interpreting most observations, this cosmological principle is applied stricto sensu: the light emitted by distant sources is assumed to propagate through a Friedmann-Lema\^itre spacetime.

Discovery of Late Holocene‐aged Acropora palmata reefs in Dry Tortugas National Park, Florida, USA: The past as a key to the future?

open access: yesThe Depositional Record, EarlyView.
Emblematic of global coral‐reef ecosystem decline, the coral ecosystem‐engineer Acropora palmata is now rare throughout much of the western Atlantic. We report for the first time, a significant record of late‐Holocene A. palmata populations that existed from ~4500 to 375 years before present in the Dry Tortugas, FL, USA.

The expensive son hypothesis [PDF]

open access: yes
In its initial form, the expensive son hypothesis postulates that sons from male-biased sexually dimorphic species require more food during growth than daughters, which ultimately incur fitness costs for mothers predominantly producing and rearing sons.

The role of refluxing deep hypersaline brines and evaporite precipitation dynamics in the Castile Formation and marginal carbonate strata (Delaware Basin, USA)

open access: yesThe Depositional Record, EarlyView.
The Upper Permian Castile Formation of the Delaware Basin, a 515.3 m (1690.6 ft) thick deep‐water evaporitic sequence dominated by anhydrite and halite, is the focus of this study. This study's sedimentological and geochemical analysis of cores from the basin's centre and margin reveals that dynamic reflux of deep hypersaline brines significantly ...
