Water Resources Research, Volume 61, Issue 12, December 2025.Abstract Groundwater dating studies rely on environmental tracers to estimate residence times, but most available reliable tracers cover either short (days to decades; e.g., 222Rn, 3H/3He, 85Kr) or extended timescales (millennia to millions of years; e.g., 4He, 36Cl, 81Kr). This leaves a critical gap in age information for intermediate residence times (

Ostracod assemblages indicating a low water level episode of Lake Peipsi at the beginning of the Holocene [PDF]
Estonian Journal of Earth Sciences, 2009 Three sediment cores from the northern part of Lake Peipsi in eastern Estonia were analysed for their ostracod content. The investigated sediments consist of late Weichselian glaciolacustrine varved and homogeneous clay, lake marl, and gyttja. Altogether

Liming Enhances Soil Phosphorus Cycling in Long‐Term Agricultural Fields
European Journal of Soil Science, Volume 76, Issue 6, November–December 2025.ABSTRACT Liming enhances both organic phosphorus (P) mineralization and the precipitation of inorganic phosphates with calcium (Ca) cations. To better understand how P storage and cycling in soil profiles are regulated by the interaction of long‐term P fertilization and liming, we collected soil samples from three German arable long‐term field ...

An aminostratigraphy of the northern Upper Rhine Graben, Germany
Journal of Quaternary Science, Volume 40, Issue 7, Page 1147-1175, October 2025.ABSTRACT The northern Upper Rhine Graben (Germany) contains a complex, quasi‐continuous Quaternary record, but constraining its chronology is challenging. This study presents the first application of amino acid geochronology for this region using Bithynia opercula to establish a relative dating framework.

Journal of Quaternary Science, Volume 40, Issue 7, Page 1212-1229, October 2025.ABSTRACT Numerous cryptotephra layers originating from Icelandic volcanoes and further afield have reached Northern Europe during the Holocene. Refining the precise timing and the relative frequency of local and distal eruptions requires well‐resolved continuous sediment archives. Lake Nautajärvi is located in central‐southern Finland (61°48′ N, 24°41′

Late Quaternary environmental changes recorded in the Danish marine molluscan faunas: Appendices 1-6 [PDF]
Geological Survey of Denmark and Greenland Bulletin, 2004 Late Quaternary, marine deposits in Denmark have yielded 247 subfossil species of molluscs. The sites are presented, and comparisons are made between the subfossil mollusc assemblages and the 278 shell-bearing mollusc species presently living in the ...

Sediments of MIS 5e age suggested by new OSL dates from the Skilvika section, west Svalbard
Polar Research, 2018 The sediment succession at Skilvika, west Svalbard, represents one of the key stratigraphic records of the Late Quaternary palaeoenvironments and glaciation history of the Svalbard/Barents Sea area.
