Coastal Marine Carbon and Air‐Sea Fluxes Quantified From pH Sensors on an Extended AUV Deployment

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
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

Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, Volume 109, Issue 2, Page 693-714, August 2026.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.
