Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract Assessing seismic and tsunami hazards along coastlines requires understanding past earthquakes and their recurrence along active submarine faults. Subaqueous paleoseismology commonly relies on sediment cores and seismic reflection data, but these methods may be limited by local site conditions or data quality.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record
Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated

Environmental DNA, Volume 8, Issue 3, May–June 2026.Sedimentary ancient DNA study revealed 138 years of hidden microsporidian (unicellular eukaryotic parasite) diversity and host–parasite dynamics in a freshwater lake. A major community shift in the 2000s, linked to anthropogenic pressures, shows how paleogenomics reveals the diversity and long‐term ecological trajectories of these previously overlooked

Bayesian improvements to 210Pb dating
, 2021 <p>Dating with <sup>210</sup>Pb has been instrumental in providing chronologies for sedimentary deposits back to around 100-150 years ago &#8212; a key period for recent environmental events such as increased pollution caused by industry developments.

A multi-year study of radioactivity in surface air and its relation to climate variables in Belgrade, Serbia [PDF]
Nuclear Technology and Radiation Protection, 2013 Activities of 7Be and 210Pb were monitored in surface air in Belgrade, Serbia, from 2004 to 2012. The measurements were taken from two locations, in an open field of a city suburb and in the central city area.
