Abstract Understanding the ventilation of the deep ocean, where most ocean carbon is stored, is essential to understanding how changes to ocean carbon budgets contribute to climate change. In the Arctic Ocean, shifts in ice cover, stratification and temperature are likely to impact carbon sequestration in the ocean interior.

ABSTRACT Although recent developments have improved clarity on the characteristics of high‐quality risk science, there is recognition that many of those characteristics relate to specific tasks taken by the risk analyst. However, the effectiveness of risk analysis and management often relies on both internal risk team activities and other external ...

Adaptive Responses of Tropical Crops: A Multi‐Scale Omics Integrated Perspective
Tropical crops integrate genomic, morphological, physiological, and ecological adaptations to thrive under extreme and variable environments. This review highlights how natural selection, domestication, and breeding shape stress resilience, resource‐use strategies, and productivity in sugarcane, banana, cassava, rubber and oil palm, offering new routes

Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment
Abstract For the first time, the Autosub Long Range (ALR) completed a fully autonomous, long‐distance (2,000 km) scientific mission, delivering new insight into coastal carbonate dynamics and air‐sea CO2 ${\text{CO}}_{2}$ fluxes. Equipped with a suite of oceanographic sensors, including a Lab‐on‐Chip (LOC) pH sensor and a Sea‐Bird SeaFET pH sensor, the
