Note on the stratigraphic position of the Zonderschot sands member of the Berchem formation (Miocene, Belgium) [PDF]
, 1980 Planktonic foraminifera are recorded from three samples of the Zonderschot Sands Member of the Berchem Formation in the type locality at Zonderschot. Altogether 15 taxa are described.

Oxygen isotopic paleotemperatures across the Runangan-Whaingaroan (Eocene-Oligocene) boundary in a New Zealand shelf sequence [PDF]
, 1981 Oxygen isotopic compositions of the tests of mainly benthic foraminifera, from sections of conformable Late Eocene (Runangan) to Early Oligocene (Whaingaroan) shelf mudstones, at both Cape Foulwind and Port Elizabeth, western South Island, indicate that ...

Quantifying Atmospheric Humidity in the Western Mediterranean During the Iron Age and the Roman Era
Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract Atmospheric moisture is a key hydroclimatic parameter that influenced ancient societies, agriculture, and ecosystems. However, quantitative constraints on pre‐industrial atmospheric humidity values are rarely available. Here, the triple oxygen (17O/16O and 18O/16O) and hydrogen (2H/1H) isotope compositions of lacustrine gypsum are used to ...

Limnology and Oceanography, Volume 70, Issue 12, Page 3621-3633, December 2025.Abstract Carbonate coral sands are an integral part of the carbon and nutrient cycles in subtropical and tropical coastal environments. Recent studies indicate that nearshore carbonate sands may be hotspots for organic matter production and respiration, but the processes and their controls are poorly understood due to a lack of noninvasive in situ ...
