Marine Policy

Marine Policy is the leading journal of ocean policy studies. Submissions to Marine Policy must contribute to the formulation and understanding of marine policy, and must be of interest to a broad audience of academics, stakeholders and officials. Marine Policy offers researchers, analysts, stakeholders and policy-makers a unique combination of analyses in the principal social science disciplines relevant to the formulation of marine policy. Articles represent perspectives from fields such as marine affairs, marine economics and resource management, political science, marine science, human ecology, international law, geography, normative theory, anthropology and similar disciplines. Focal areas include, but are not limited to: international, regional and national marine policies; institutional arrangements for the management and regulation of marine activities; conflict resolution; marine pollution and environment; conservation and use of marine resources. We are not a technical journal and will recommend that overly-technical papers are transferred to other more relevant journals. We will consider policy papers that do include a technical analysis, but only if this directly informs a policy analysis or discussion. We request that authors minimise the inclusion of formulas and model details needed to explain the methods and analysis in the main text. Detailed formulae and calculations should be included in an appendix or supplementary materials, and summarised in the main text.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
