The influence of a cooling water system on waterbird habitat use in a coastal environment

open access: yesIbis, Volume 168, Issue 3, Page 1148-1158, July 2026.
This study investigated the impact of a cooling water system at a nuclear power plant in northern Europe on coastal waterbird habitat use. In winter, the cooling water system provided preferential areas for waterbirds with warm productive waters, and, more importantly, with ice‐free areas.
