Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

Contemporaneous formation of self-secondaries and layered ejecta deposits on Mars
Self-secondaries are secondary craters formed in cogenetic ejecta deposits. Bearing important information on cratering mechanics and the applicability of remote age-determination technique using crater statistics, the spatial distribution of self ...

Forecasting volcanic ash dispersal and coeval resuspension during the April-May 2015 Calbuco eruption [PDF]
Atmospheric dispersion of volcanic ash from explosive eruptions or from subsequent fallout deposit resuspension causes a range of impacts and disruptions on human activities and ecosystems.

ABSTRACT This paper examines transport amphorae of Greek/Aegean types from the 7th–4th c. BCE imported to the Phoenician coastal settlement of Tell el‐Burak, Lebanon. We present a selection of 58 pieces analyzed by typological, chemical (NAA), and petrographic approaches.

A new chronology for the Moon and Mercury
In this paper we present a new method for dating the surface of the Moon, obtained by modeling the incoming flux of impactors and converting it into a size distribution of resulting craters.

Lunar cratering chronology: Statistical fluctuation of crater production frequency and its effect on age determination [PDF]
Abstract The crater frequency is often used to determine ages of planetary surfaces. In this study, we evaluate the statistical fluctuation of the crater frequency and its effect on age determination using a Monte Carlo simulation prior to the SELENE (KAGUYA) / Terrain Camera acquiring extensive high-resolution images over the entire Moon. We

Application of Data Assimilation Methods to Reconstruct the 3–5 December 2015 Etna Eruption
Abstract The assessment of volcanic hazards is crucial to develop effective emergency plans, especially for volcanoes close to urban areas or under air traffic routes. Impact assessment for expected scenarios relies on underlying numerical models that require eruption source parameters as inputs, and forecasts drastically depend on their robust ...

A review of late Quaternary silicic and some other tephra formations from New Zealand: their stratigraphy, nomenclature, distribution, volume, and age. [PDF]
The stratigraphic relationships and distribution of 36 named late Quaternary (≤c. 50 000 yr B P.) silicic tephra formations, erupted from 4 volcanic centres—Okataina, Taupo, Maroa, and Tuhua (Mayor Island)—are presented.

Abstract Igneous Plumbing Systems in sedimentary basins comprise a complex of interconnected intrusive bodies that lead to volcano formation, though their 3D distribution and dynamics are not fully understood. We characterized the post‐breakup igneous plumbing systems at the Santos and Campos Basins using wells and 3D high‐resolution seismic and ...
