Abstract Although the North Pacific Subtropical Gyre (NPSG) is among the most oligotrophic regions, its vast expanse means that small productivity shifts can alter the global carbon budget. We quantified net community production (NCP) from high‐resolution O2 ${\mathrm{O}}_{2}$/Ar measurements and gross primary production (GPP) from 18O incubations in ...

Mesoscale and Submesoscale Variability in the Indian Ocean
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

The Milankovitch Theory Revisited to Explain the Mid-Pleistocene and Early Quaternary Transitions
The theory of orbital forcing as formulated by Milankovitch involves the mediation by the advance (retreat) of ice sheets and the resulting variations in terrestrial albedo. This approach poses a major problem: that of the period of glacial cycles, which

Abstract The Atlantic Meridional Overturning Circulation (AMOC) plays an important role in regulating Earth's climate through inter‐hemispheric heat transport and has undergone substantial variations during past climate transitions. Sedimentary 231Pa/230Th is widely used to reconstruct AMOC strength, yet its application is complicated by its ...

Forces Shaping Diversity of Hydrogen Peroxide Detoxification Potential in Ocean Microbial Ecosystems
Marine microbes which lack catalases, like Prochlorococcus, depend on ‘helpers’, like catalase‐positive Alteromonas, for hydrogen peroxide detoxification. Our results indicate diverse and distinct distributions of catalases (katG, katE and manganese catalase) among community members.

Nature of Plastic Marine Pollution in the Subtropical Gyres
The abundance and distribution of plastic debris in the marine environment show patterns of near- and offshore generation, migration toward and accumulation in the subtropical gyres, fragmentation, and redistribution globally. Ecological impacts in the subtropical gyres include invasive species transport and rampant ingestion and entanglement; yet ...

ABSTRACT Snakes are experiencing global population decline due to habitat loss, environmental degradation, pollution and climate change, yet effective conservation is often hindered by their cryptic behaviour and low detectability. In this study, we conducted targeted surveys and estimated detection probabilities for the endangered grey snake ...

The impact of resolving western boundary currents and mesoscale eddies on a carbon circulation simulation for the North Pacific Ocean is investigated to evaluate the merits of using high‐resolution ocean biogeochemical models for climate projections ...

Microbial mats in dinosaur ichnocoenoses
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.
