A continuous 500‐year sediment record of inundation by local and distant tsunamis in South‐Central Chile (40.1°S)

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1285-1310, November 2025.
Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

The performance of thin NaI(Tl) scintillator plate for dark matter search

open access: yes, 2006
A thin (0.05cm) and wide area (5cmX5cm) NaI(Tl) scintillator was developed. The performance of the thin NaI(Tl) plate, energy resolution, single photoelectron energy and position sensitivity were tested.

Climate warming disrupts zooplankton phenology and overwintering strategies

open access: yesLimnology and Oceanography, Volume 70, Issue 11, Page 3277-3291, November 2025.
Abstract Zooplankton are crucial for food webs and biogeochemical cycles. However, warming associated with climate change may alter their seasonal timing and reproductive strategies. This study investigated how long‐term warming impacted zooplankton (mainly copepods) phenology and overwintering strategies by comparing a Baltic Sea bay, heated by warm ...

New Insights Into the Proposed Geomagnetic Excursion Hilina Pali From High‐Resolution Lake Sediment Cores From the Polar Ural Mountains, Arctic Russia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract This study presents paleomagnetic records from three 24 m‐long sediment cores from the neighboring lakes Bolshoye Shchuch'ye and Maloye Shchuch'ye, located about 10 km apart in the Polar Urals in northern Russia. The age model, based on radiocarbon dating and varve counting, shows that the sediment sequences reach back up to about 23.5 ka cal.

Datació de Posidonia oceanica mitjançant 210Pb

open access: yes, 2021
La Posidonia oceanica és una fanerògama marina endèmica del Mediterrani. Es tracta d'una espècie molt important a les zones costeres, i en les últimes dècades la seva producció s'ha vist reduïda. En aquest estudi s'ha volgut demostrar la viabilitat d'utilitzar l'espècie Posidonia oceanica com a arxiu de contaminants al llarg del temps, alhora que s'han
