Estimation of stresses in atmospheric ice during aeolian vibration of power transmission lines [PDF]

open access: yes, 2010
Aeolian vibration in bare and iced cable was simulated using the theory of cable vibration. High frequency vibration creates stresses in the cable and consequently in the ice covering that cable, which may result in ice failure and eventually ice ...

Procurement of Senonian Flint for Bladelets Production at the Early PPNB Site of Nahal Zahal in the Northern Negev Established for the First Time Using Chemical Composition Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT The hypotheses of Senonian flint to be a prime source of prehistoric “chalcedony” flint artefacts from the Negev Desert (Israel) was not investigated in detail thus far. By combining trace‐element profiling with statistical interpretation, ten flint items from Nahal Zahal, an Early Pre‐Pottery Neolithic B site in the northern Negev, were ...

The Morphology and Evolution of Transverse Aeolian Ridges on Mars [PDF]

open access: yes, 2021
Transverse aeolian ridges (TARs) are enigmatic and largely relict bedforms on the surface of Mars. TARs are sparsely distributed but common on Mars, but their history, preservation, and past role in the sediment cycle is not well understood.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

open access: yesBoreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, 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.

Prioritizing site groups for intrinsic biodiversity assets using complementarity and not just rarity

open access: yesConservation Science and Practice, EarlyView.
Conservation practitioners rightfully focus on at‐risk species when valuing biodiversity assets and prioritizing spatial units. We compared and combined numbers of at‐risk species with four other community metrics using surveys of vascular plants at wetlands in a preserve network in Illinois, USA.

Volatile Conduits Beneath Vulcano Island (Italy) Revealed by High‐Resolution Nodal Local Earthquake Tomography During Volcanic Unrest

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Understanding shallow magmatic and hydrothermal systems at active volcanoes is essential for interpreting unrest and forecasting eruptions. We present the first high‐resolution three‐dimensional Vp $Vp$, Vs $Vs$, and Vp/Vs $Vp/Vs$ models of Vulcano Island, Aeolian Islands, Italy, derived from a dense nodal seismic network.

Summary of the Second International Planetary Dunes Workshop: Planetary Analogs — Integrating Models, Remote Sensing, and Field Data, Alamosa, Colorado, USA, May 18–21, 2010 [PDF]

open access: yes, 2010
The Second International Planetary Dunes Workshop took place in Alamosa, Colorado, USA from May 18–21, 2010. The workshop brought together researchers from diverse backgrounds to foster discussion and collaboration regarding terrestrial and extra ...

Underestimation of Planetary Contraction Due To Obscuration by Surface Roughness: The Case of Mercury

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Estimating Mercury's radial contraction is key to understanding the planet's geodynamic evolution. Contraction has been inferred from mapped shortening structures, whose heterogeneous distribution contradicts the isotropic contraction expected from global cooling.
