Riverine Biogeochemical Exports From Major Watersheds to the Northwest Patagonian Estuarine Network

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract River discharge considerably influences marine ecosystems through hydrological and biogeochemical drivers. Measuring baseline variability of riverine inputs, and their relation to anthropogenic land‐use impacts and global climate stressors affecting watersheds is therefore crucial for managing coastal marine ecosystems.

PRESSURE PREDICTION AND UNDERBALANCED DRILLING IN THE DEEPWATER NIGER DELTA [PDF]

, 2012
The mechanisms that cause overpressure can be broadly classified into two categories: loading and unloading. This study looks at eight wells from the deepwater Niger Delta; the wells were evaluated with three aims in mind. The first aim was to determine

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters

Global Change Biology, Volume 32, Issue 8, August 2026.
Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.
