Analysis by pXRF of Prehistoric Obsidian Artifacts From Several Sites on Ustica (Italy): Long-Distance Open-Water Distribution From Multiple Island Sources During the Neolithic and Bronze Ages

open access: yesOpen Archaeology, 2020
The small island of Ustica was a regular part of the obsidian distribution network in the central Mediterranean, despite its location more than 50 km north of western Sicily.

Investigating the influence of climate and volcanic surface aging on fluvial erosion: A case study of Réunion Island, Indian Ocean

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 4, April 2026.
Réunion Island is marked by gradients in both precipitation and surface age. Analyzing correlations between metrics related to precipitation, age, and drainage basin morphology, we demonstrate how volcanic surface age impacts the effects of average precipitation and precipitation variability on fluvial erosion.

The Early and Middle Bronze Age Textile Tools from the Aeolian Islands (Italy)

open access: yesFasciculi Archaeologiae Historicae, 2018
The Aeolian ceramic textile tools dated to the advanced Early and Middle Bronze Age (c. 1600-1250 BC) comprise the only evidence for textile manufacture and are a unique source of information about the technology of textile production used in the Early ...

Challenges and Opportunities for National‐Scale Projections of Future Coastal Landscape Change

open access: yesEarth's Future, Volume 14, Issue 4, April 2026.
Abstract Local to global scale projections of future coastal landscape change are essential to improve land and resource management decisions that aim to prepare for and reduce risk exposure to impending coastal hazards. However, the availability of actionable knowledge is often limited due to the complexity of drivers of change, their consequences ...

Fluids mobilization in Arabia Terra, Mars: depth of pressurized reservoir from mounds self-similar clustering

open access: yes, 2019
Arabia Terra is a region of Mars where signs of past-water occurrence are recorded in several landforms. Broad and local scale geomorphological, compositional and hydrological analyses point towards pervasive fluid circulation through time.

Evidence of crustal melting events below the Island of Salina (Aeolian Atc, Southern Italy) [PDF]

open access: yes, 2004
Quartz-rich xenoliths hosted in the basaltic-andesitic and andesitic lavas of Monte dei Porri, in the island of Salina, contain fluid and melt inclusions whose study makes it possible to trace back the magma ascent path of this volcano; moreover, they ...

Upper Ocean Cycling of Iron South of the Polar Front: Biological Patterns and Processes

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Samples from the upper 300 m along the 52°S band, south of the Antarctic Polar Front in the Atlantic sector of the Southern Ocean, including a 3‐week monitoring of a persistent bloom, were analyzed to advance our understanding of iron cycling and supply to recurrent phytoplankton blooms.

Iron and Manganese Cycling in the Atlantifying Barents Sea: Concentrated Inputs and Emerging Limitations

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Dissolved iron (dFe) and manganese (dMn) are essential micronutrients required in marine primary production; however, their low availability limits productivity and impacts the efficiency of the biological carbon pump. Therefore, it is crucial to elucidate their sources, sinks, and internal cycling.
