期刊介绍:
A bilingual open-access publication, Ciencias Marinas (CM) is an international peer-reviewed journal that contains original research findings in all areas of marine science. It is published quarterly by the Autonomous University of Baja California, Mexico, and all its contents are publicly available on our journal website. Though a limited number of copies are still printed, the journal is mainly distributed in its electronic format.
CM was conceived in 1973 as part of an academic project aimed to entice local researchers to publicly disclose their findings by adopting the culture of peer-review publishing. This academic project evolved into an international journal after accepting papers from researchers in the United States and, eventually, other parts of the world. Because of the diversity in authorship, CM issues were initially published in either Spanish or English, and occasionally in both languages. It was not until 1984 when CM included both language versions of all its contents, and it then became the fully bilingual journal it still is today. At CM we believe our inclusive format allows us not only to address a wider range of submissions from international authors but also to make published findings available to a wider international audience.
So whether you are looking for information on the redfish in Icelandic waters or the physical and biological properties of the Gulf of California, feel free to peruse CM contents. You may find them to provide source material for your research.
