Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Study of the isothermal equation of state and elastic properties for hcp-transition metals at high pressure

Chemical Physics Impact
A theoretical model of the equation of state based on Eulerian finite theory for high pressure has recently been reported by Singh et al. The adopted model successfully predicted the elastic properties of geophysical minerals and prototype solids and the

ISSM-SESAW v1.0: mesh-based computation of gravitationally consistent sea-level and geodetic signatures caused by cryosphere and climate driven mass change [PDF]

Geoscientific Model Development, 2016
A classical Green's function approach for computing gravitationally consistent sea-level variations associated with mass redistribution on the earth's surface employed in contemporary sea-level models naturally suits the spectral methods for numerical ...

Atypical Long Barrows in the Cöeby Neolithic Cemetery (Trédion, Morbihan, France)? The Contribution of Electrical Surveys

Archaeological Prospection, EarlyView.
ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.
