Marine scientists broadly agree on which major threats influence the sustainability of marine environments worldwide. Recent studies argue that such shared perceptions crucially shape scientific agendas and are subject to a confirmation bias. To investigate this issue, our paper takes stock of the shared understanding in marine science of the most pertinent, worldwide threats and impacts that currently affect marine environments. Additionally, we show disciplinary differences in the perception of the global, marine environmental change. Finally, we discuss what the findings imply for further improvement of interdisciplinary marine science. – Boonstra et al. 2015
