IntroductionOffshore wind energy development (OWED) has been identified as a major contributor to the aspired growth in Norwegian renewable energy production. Spatially explicit vulnerability assessments are necessary to select sites that minimize th

Seabirds breed in high density colonies, but the factors determining colony position aren't clear. Here, Sandvik et al. show that small-scale coastal topography is related to likely variation in fish larval abundance, which predicts the distribution
