Resolving the Interpretation of Magnetic Coercivity Components From Backfield Isothermal Remanence Curves Using Unmixing of Non‐Linear Preisach Maps: Application to Loess‐Paleosol Sequences

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 6, June 2024.
Abstract Unmixing of remanent magnetization curves, either isothermal remanent magnetization (IRM) or backfield IRM, is widely used in rock magnetic and environmental magnetic studies to discriminate between magnetic coercivity components of different origins. However, the wide range of physical properties of natural magnetic particles gives rise to an

Role of bottom water chemistry in the formation of fibrous magnesium calcite at methane seeps in the Black Sea

open access: yesSedimentology, Volume 71, Issue 4, Page 1193-1213, June 2024.
ABSTRACT Climate change poses a significant challenge for life on Earth. Different climate modes have been shown to come along with changes of the magnesium/calcium (Mg/Ca) ratio of seawater, and such changes are believed to control the primary mineral phase of marine authigenic carbonates.

Monitoring plant diversity in wind farm areas: An approach to early detection of alien plant species

open access: yesConservation Science and Practice, Volume 6, Issue 4, April 2024.
Although the establishment of alien species in disturbed habitats is a well‐studied subject, so far few studies have investigated the contribution of wind farms to their spread around wind turbines. To fill this knowledge gap, we conducted a multiyear presence‐only survey of plant communities from wind farms located within protected areas to test the ...
