Consequences of a Global Slowdown in Seafloor Spreading for Sea Level and Mantle Heat Loss

Geochemistry, Geophysics, Geosystems
Variations in global mean sea level over millions of years originate from changes in both the climate and solid Earth systems. Most previous studies of the solid Earth contribution to sea level focused on the past 100 Myr or longer with a temporal ...

Deep Dark Futures: Foresighting Human Impacts on Mesopelagic Ecosystem Services

Fish and Fisheries, Volume 27, Issue 4, Page 876-894, July 2026.
This study uses foresighting to explore four plausible future scenarios of human activity affecting mesopelagic ecosystem services; provisioning, regulating, supporting and cultural. Using participatory scenario development, qualitative network modelling and indicator design, we assess systemic risks and early warning signals linked to harvest, climate

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Photosynthetic primary production in the Mesoproterozoic

New Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.

Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).

A Spreading‐Rate Dependence for Periodic Signals Embedded in Otherwise Aperiodic Abyssal Hills

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract I present evidence, through an empirical pre‐whitening analysis, that periodic signals are embedded in otherwise aperiodic abyssal hills across paleo‐spreading rates ranging from 1 to 9 cm/yr (half rate). Data are comprised of archival trackline and multibeam bathymetry profiles in north and south Atlantic Oceans, Pacific‐Antarctic Ridge ...

Unraveling the Source Locations of Short‐Period Secondary Microseisms

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Primary and secondary microseisms are generated by ocean wave interactions, with the latter occasionally split into short‐ and long‐period bands in some regions. The short‐period secondary microseism (SPSM) sources have traditionally been associated with nearby coastal segments, suggesting a more uniform distribution across shorelines.

Interactive Climate Projection via Conditional Generative AI

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Dynamical Earth System Models are extremely expensive, requiring ∼106 core‐hours for century‐scale simulations. This limits climate projections to only a few Shared Socioeconomic Pathways (SSPs) and leaves numerous policy trajectories unexplored.

Maximum Lifetime of the Vegetative Biosphere

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract We use a three‐dimensional model to calculate steady‐state climates at various intervals in Earth's future, across a parameter space of increasing insolation and decreasing CO2 ${\text{CO}}_{2}$ mixing ratio. Comparison with prior results shows an overestimation of warming by one‐dimensional models when solar constant is increased and CO2 ...
