A Novel Approach for Autonomous Densely Spaced Acquisition of Buried Objects in Intertidal Environments—Field Examples From Avaldsnes, Norway

Archaeological Prospection, Volume 32, Issue 1, Page 59-76, January/March 2025.
ABSTRACT Underwater archaeology relies on expensive and time‐consuming invasive methods for identifying and excavating objects buried in the seabed or identifying layers in shallow and intertidal environments. Especially shallow and intertidal environments are challenging due to locally high levels of sedimentation that offer good conditions for ...

Spatial Distribution of Thaw Depth in Palsas Estimated From Optical Unoccupied Aerial Systems Data

Permafrost and Periglacial Processes, Volume 36, Issue 1, Page 22-36, January/March 2025.
ABSTRACT Maximum seasonal thaw depth, referred to as active layer thickness (ALT), is one of the key parameters used to monitor permafrost conditions. ALT maps based on interpolation of point measurements or derived from coarse or moderate spatial resolution satellite data often hide small‐scale spatial variations in thaw depth resulting from ...

Paving the Way for Low‐Carbon Shipping Fuels in Long‐Haul Trade Routes

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
In 2023, the International Maritime Organization strengthened its ambition, aiming at net‐zero greenhouse gas (GHG) emissions by 2050. This goal depends on the replacement of oil‐derived fuels by alternative fuels and motorizations that bring the risk of technological lock‐in and increasing global trade costs. The establishment of low‐carbon (LC) trade

Near‐Real‐Time Identification of the Source of Ionospheric Disturbances

Journal of Geophysical Research: Space Physics, Volume 129, Issue 11, November 2024.
Abstract The ionosphere is characterized by a large number of disturbances generated in response to a wide range of phenomena, including natural hazards, space weather and man‐made events. Identification of the origin of ionospheric disturbances (ID), especially in real or near‐real‐time (NRT), is an extremely difficult task, and it is one of the most ...

Ionospheric Nowcasting Over Italy Through Data Assimilation: A Synergy Between IRI UP and IONORING

Space Weather, Volume 22, Issue 5, May 2024.
Abstract An accurate modeling of the ionosphere electron density is pivotal to guarantee the effective operation of communication and navigation systems, particularly during Space Weather events. Despite the crucial contribution of empirical models like the International Reference Ionosphere (IRI), their limitations in predicting ionospheric ...
