III. MANUSCRIPT VERIFICATION AND FORMAT: The manuscript submitted to the Vietnam Journal of Marine Science and Technology must not have been published before. This manuscript has not been reviewed for publication in another journal. All authors must approve the publication. If accepted, it will not be published elsewhere in the same form, in English, or in any other language (including the electronic file the author receives).
IV. SUBMISSION PROCESS: The manuscript submission must be completed online through the Journal’s homepage. The Vietnam Journal of Marine Science and Technology author will be guided on the submission process step by step through the creation and upload of the manuscript. The system will automatically allocate the ID to the original manuscript used during the review and editing processes and allocate the digital object identifier (DOI) to the article after publication. All the correspondence, notices of editors and authors, along with the comments of reviewers, will be archived on the system.
V. REVIEW PROCESS: Each submitted manuscript is usually reviewed and evaluated by two independent reviewers. Review time is within two months. The review will be sent to the author by the editor; the author needs to revise and improve the manuscript before publication. The time limit for the author to revise the manuscript is three months. The revised manuscript received after this time limit will be considered a new manuscript, and the review process will be performed from the beginning.
VI. MANUSCRIPT REVISION: When there are reviewers’ comments, the author is requested to make the manuscript revision, accompanied by a reply to all reviewers’ comments. The author should highlight changes in the manuscript so that the editor and reviewers can follow the revision.

The author’s tasks in the manuscript editing are as follows: The author will be requested to recheck the manuscript before the editor prepares the proof of the article. The author must recheck this proof to avoid any mistakes in the editing process. After the English proofreading, the author must verify the prepress proof once again before receiving the final article. Accordingly, the author should read the manuscript at least three times until the last article is completed. Authors will receive a printed copy after 20 days of electronic publication on the homepage of the Journal.
VIII. USE OF DIGITAL OBJECT IDENTIFIER (DOI): DOI can be used to cite and link to electronic documents. DOI consists of unique serial numbers assigned to a published paper. DOI is guaranteed to be unchanged; therefore, it is an ideal means for citing references, for example, an article published in the Vietnam Journal of Marine Science and Technology: http://dx.doi.org/10.15625/1859-3097/xxx
