A Passive Probe for Subsurface Oceans and Liquid Water in Jupiter's Icy Moons

, 2014
We describe an interferometric reflectometer method for passive detection of subsurface oceans and liquid water in Jovian icy moons using Jupiter's decametric radio emission (DAM).

First Disk-Resolved Millimeter Observations Of Io's Surface And SO2 Atmosphere [PDF]

, 2008
Aims. In spite of considerable progress in the last two decades, Io's atmosphere remains poorly understood. The goal of this work is to improve our understanding of its spatial distribution, temperature and dynamics. Methods.

Passive Microwave Radiometry and Active Radar Sounding as Complementary Tools for Geophysical Investigations of Icy Ocean Worlds

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Juno Microwave Radiometer (MWR) observations of Europa and Ganymede offer critical insights into the icy shells of these moons ahead of NASA's Europa Clipper and ESA's JUpiter ICy moons Explorer (JUICE) missions. Both missions are equipped with active radar sounders designed to address key unknowns such as ice shell thickness, thermal state ...

Ammonites and magnetostratigraphy of the Berriasian–Valanginian boundary deposits from eastern Crimea

Geologica Carpathica, 2017
Euthymi, Crassicostatum and Callisto ammonite subzones, correlable with Paramimounum, Picteti, and Alpillensis subzones and probably with the Late Berriasian Otopeta Subzone of the Boissieri Standard Zone have been recognized in calcareous clays of the ...

Eclipses of the inner satellites of Jupiter observed in 2015

, 2016
During the 2014-2015 campaign of mutual events, we recorded ground-based photometric observations of eclipses of Amalthea (JV) and, for the first time, Thebe (JXIV) by the Galilean moons.

Asymmetric Crater Relaxation on an Ice‐Rich Ceres Driven by Insolation

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Ceres has a high ice content within its crust and is the closest dwarf planet to the sun. The resultant high insolation levels at Ceres' surface (in comparison to the outer solar system) leads to high variations in surface temperature, which is dependent on both latitude and orientation of the slope (i.e., equatorward‐ or poleward‐facing).

Targeted Application of Herbicides in Maize (Zea mays L.) Using a Camera‐Controlled Boom‐Sprayer

Weed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Targeted application technologies combine imaging systems for weed detection with single nozzle control for herbicide application. The potential of herbicide saving using targeted application is very high because weeds are usually distributed heterogeneously in agricultural fields.

Genetic Analysis of the Brown Bear Sub-Population in the Pindos Mountain, Central Greece: Insights into Population Status and Conservation

Animals
Habitat fragmentation poses a significant threat to the existence and reproduction of large carnivores, such as brown bears, as it affects the genetic connectivity of populations and, consequently, their long-term viability.

Pitch Angle Distributions of Energetic Electrons Near Ganymede: Galileo EPD Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Galileo flew‐by Ganymede six times between 1996 and 2000. The Energetic Particles Detector (EPD) performed energy resolved, directional electron measurements, and together with the magnetometer data, pitch angle distributions (PADs) could be derived.

Temporal Changes in Europa's Ice Shell Thickness: Insights From Models of Convection

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Europa is characterized by a thin ice Ih shell overlying a subsurface ocean and a large solid core. Estimates of the outer ice shell's thickness range from a few kilometers to several tens of kilometers, with strong implications for Europa's thermal and geological history.
