Diagenetic Effect on Planktic Foraminiferal Mg/Ca Records in the Arctic Ocean

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Mg/Ca ratios in planktic foraminifera have long been used as a thermometer to reconstruct the past climate. However, this study revealed that in certain intervals, the Mg/Ca ratios of the planktic foraminifer Neogloboquadrina pachyderma, a widespread species in the Arctic Ocean, displayed anomalously high values which could severely bias paleo‐

Plate Interactions and Mantle Flows Beneath the Caribbean and Adjacent Regions Revealed by P‐Wave Anisotropic Tomography

open access: yesTectonics, Volume 45, Issue 3, March 2026.
Abstract We determine the first P‐wave azimuthal and radial anisotropy tomography beneath the Caribbean and its adjacent regions. The Cocos and Atlantic Plates are imaged as high‐velocity (high‐V) zones down to ∼1,600 km depth and they have subducted independently beneath the Caribbean Plate.
