The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, Volume 37, Issue 1, Page 317-355, November 2026.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Net Carbon Transfer From Ocean to Land During the Last Deglaciation Synchronous With Sea Level Rise and Lagging Atmospheric CO2 by Several Millennia

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The sequence of events in the global carbon cycle during deglaciations is not entirely understood. Here, we analyze mean ocean δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O in an updated compilation of foraminiferal stable isotope data comprising 902 time series from 381 sediment cores, with individual records covering intervals within the ...

Sandy Turbidity Current Acts as a Rusty Carbon Pump at the Shelf Edge

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Sandy turbidity currents (STCs) efficiently sequester organic carbon (OC) through rapid burial. Yet our understanding of OC preservation within STC deposits remains far less constrained, especially considering STC deposits as an inferred major sink for iron‐bound OC (Fe‐OC), a long‐term stabilized form of OC.

Millennial‐Scale Deoxygenation in the Southern California Oxygen Minimum Zone Over the Last Glacial Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Past variability of oxygen minimum zones (OMZs) provides key insights into future ocean deoxygenation. However, California margin OMZ records remain temporally limited, restricting evaluation of mechanisms across full glacial–interglacial cycles.

Zero & N‐Inflated Overdispersed Binomial Models for Sum‐Constrained Poisson Count Processes

Environmetrics, Volume 37, Issue 7, October 2026.
ABSTRACT Ecological monitoring programmes and palaeoecological analyses play a key role in understanding how biodiversity, including plants and wildlife, respond to environmental factors such as climate change or biotic competition. Such data are typically compositional in nature, and a common challenge in the analysis of ecological compositional data ...
