The source‐to‐sea nexus between water and ocean law: An international and EU perspective

Review of European, Comparative &International Environmental Law, EarlyView.
Abstract The source‐to‐sea (S2S) approach provides a systemic framework for analysing the governance of naturally interconnected freshwater and marine ecosystems. This paper examines the extent to which the S2S approach is reflected in key international and EU water and ocean law instruments, as well as the legal and governance implications of said ...

Monitoring Groundwater Pumping Using Time‐Lapse Tomography From Ambient Seismic Noise

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Management of water resources will be of critical importance as the effects of climate change accelerate. This implies the need to monitor water resources with high spatial and temporal resolution. One way to meet this need could be passive seismic methods using ambient seismic noise. In this study, we present a novel approach using time‐lapse
