Late Quaternary climatic variability in the Eastern Mediterranean recorded in Hermes Cave, Corinth Rift, Greece

Journal of Quaternary Science, EarlyView.
ABSTRACT The Greek peninsula lies at the intersection of major atmospheric circulation systems, making it a key location for reconstructing past climate variability in the Eastern Mediterranean. In this study, we present a new high‐resolution multi‐proxy speleothem record from Hermes Cave, located on the shoulder of the Corinth Rift in southern Greece.

Reconstruction of Petermann glacier velocity time series using multi-source remote sensing images

International Journal of Applied Earth Observations and Geoinformation
Glacier velocity is one of the crucial parameters in the research of glacier dynamics. Synthetic aperture radar (SAR), as an active microwave sensor, represents a common method to monitor glacier velocity.

Eco‐Friendly Surfactants From Pithecellobium dulce: Extraction, Characterization and Surface Activity

Journal of Surfactants and Detergents, EarlyView.
Schematic representation of the comprehensive analysis of saponins extracted form of Pithecellobium dulce (Roxb.) Benth. ABSTRACT The widespread use of synthetic surfactants in industrial and domestic applications has raised environmental concerns due to their biodegradability and ecological issues.

Ferulic acid‐impregnated sodium alginate–pectin biopolymer film for active packaging and shelf‐life extension of potato chips

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study explores the development of active films incorporating ferulic acid (FA), a natural antioxidant, at concentrations of 0 (F1), 2.5 (F2), and 5 g L−1 (F3) into sodium alginate (SA; 13 g kg−1) and pectin (P; 10 g kg−1) matrix.

Northern Eurasia Future Initiative (NEFI): facing the challenges and pathways of global change in the twenty-first century [PDF]

, 2017
During the past several decades, the Earth system has changed significantly, especially across Northern Eurasia. Changes in the socio-economic conditions of the larger countries in the region have also resulted in a variety of regional environmental ...

Does Palsa Thaw in Northern Finland Contribute to Remobilisation of Metals Accumulated in Peat Into Surface Waters?

Land Degradation &Development, EarlyView.
ABSTRACT Permafrost is rapidly degrading in the sporadic zone, including palsa mires in Scandinavia. Peatlands in the area have likely accumulated heavy metals from atmospheric deposition of industrial contaminants in the wider region. As the palsa mire chemical composition is not well known, and in other permafrost regions the permafrost thaw may ...

Remote-sensing characterization of surging glaciers in High Mountain Asia in the past two decades

Frontiers in Earth Science
Glacier surge represents a special glacier behavior with abnormally high flow speeds, which can trigger catastrophic events, such as high-speed ice avalanches and glacial lake outburst floods, transforming landforms in the mountain cryosphere and ...

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids

Lipids, EarlyView.
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...

A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped
