Sedimentary biogeochemical provinces in the northern limit of the oxygen minimum zone from the northeastern Mexican Pacific

open access: yesSedimentology, Volume 73, Issue 5, Page 1403-1420, August 2026.
ABSTRACT Continental margins are reservoirs of materials of terrestrial and marine origin, and they play a crucial role in understanding the spatial and temporal variability of biogeochemical cycles. This, in turn, provides insights into the development and intensity of oxygen minimum zones (OMZs).

Tree‐Ring Oxygen Isotope Values During the Last Glacial Maximum and Insights to Future Changes in Climate

open access: yesTerra Nova, Volume 38, Issue 4, Page 259-265, August 2026.
ABSTRACT Annual tree‐ring oxygen‐isotope values were measured from sections of two fossil logs of Picea mariana (black spruce) recovered from last glacial maximum proglacial sediment in Illinois, USA. Collectively, the specimens date from ca. 25,130 to 24,720 cal years BP.

Enhanced Orbital‐Forcing Sensitivity of Northern High Latitude Temperatures in the Late Cretaceous Relative to Modern Geography

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Orbital forcing is a primary driver of paleoclimate change, but its influence on deep time climates, particularly in the polar regions of the Late Cretaceous, is poorly understood. Here, we conduct climate simulations with an atmosphere‐ocean‐vegetation coupled model, MIROC4mV, to investigate the response of northern high latitude temperature ...

Invisible Ship Tracks Produce Mean‐State Cloud Microphysics Perturbation in Tropical Trade Cumulus

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Aerosol effects in cumulus‐topped boundary layers remain relatively unconstrained and drive uncertainty in climate modeling. We assess the impacts of shipping aerosol on trade cumulus, combining satellite retrievals and large eddy simulations (LES).

Dansgaard‐Oeschger Events Recorded in Low‐Latitude Marine Sediments and Teleconnection With High‐Latitude Climate Variations

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Dansgaard‐Oeschger (D‐O) events are millennial‐scale high‐latitude climate oscillations with abrupt climate transitions between stadial and interstadial conditions, which are well recorded in and outside of high northern latitudes. However, their signal propagation mechanisms from high to low latitudes are uncertain.
