Marine Science

Marine Science publishes articles, short communications, and critical reviews that contribute to our scientific understanding of marine systems and the impact of human activities. The Journal serves as a foundation for scientific advice across the broad spectrum of management and conservation issues related to the marine environment. Oceanography, marine habitats, living resources, ecology and related management topics constitute the key elements of papers eligible for publication. Integrated studies that bridge gaps between traditional disciplines are particularly welcome. The scope of the journal also includes economic, social, and public administration studies to the extent that they are directly related to management of the seas and are of general interest to marine scientists. Papers of both fundamental and applied approaches are accepted.
