Predicting drivers and distributions of deep-sea ecosystems: A cold-water coral case study
Little is yet known about species distribution patterns and physical drivers in deep-sea environments due the expensive and time consuming sampling effort. The increasing need to manage and protect vulnerable marine ecosystems, such as cold-water corals, has motivated the use of predictive modelling...

Little is yet known about species distribution patterns and physical drivers in deep-sea environments due the expensive and time consuming sampling effort. The increasing need to manage and protect vulnerable marine ecosystems, such as cold-water corals, has motivated the use of predictive modelling tools, which allow assessment of potential species or habitat distribution on larger spatial scales and resolution than traditionally accomplished by individual surveys. Advances in acoustic remote sensing, oceanographic modelling and sampling technology now provide high quality datasets, facilitating species distribution modelling with high spatial detail. In this study, we used high resolution data (250 m grid size) from a newly developed hydrodynamic model to explore linkages between key physical drivers and occurrences of the cold-water coral Lophelia pertusa in selected areas of the NE Atlantic (Mohn et al., 2014).
