Dear Colleagues,

The ocean, along with the atmosphere, cryosphere, and soil, is a key component of the Earth climate system. Primarily, it serves as an accumulator of climate variability contributing to the formation of the Earth climate. The world ocean and its water areas play an important role in economic activity: transport, fishing, hydrocarbon production on the shelf, recreation, etc. Therefore, it is important to have the most complete information possible on the state of the oceans and seas to deliver scientific and practical needs.

There are a number of practical techniques for obtaining such information, which are mainly direct or indirect measurements of oceanographic characteristics. Thus, modern satellite observations make it possible to obtain information on sea surface height and temperature, while buoys and profilers provide information on the velocity of currents, temperature, and salinity in the seawater column. However, as a rule, these data are fragmented due to being spatiotemporal tracks with the partial or total absence of data in the deep ocean and/or in polar regions. An alternative way to examine the world ocean waters is the development of mathematical models of circulation, together with their practical implementation and the design of computational experiments. This approach has its errors since it is impossible to describe complex systems completely by models which always have various limitations. It is well known that the best results in reproducing marine and oceanic characteristics can be obtained using a combination of numerical modeling with the assimilation of observational data. Moreover, the most accurate predictions of the marine environment state require the application of numerical simulation.

This issue aims to cover different aspects of oceanic and marine circulation in the context of numerical simulation and analysis of observations, and, most desirably, combination of these two approaches. The authors can focus on original numerical methods, techniques of data collection and processing, as well as implementation of all these tools for the investigation of physical processes with possible scientific results. Moreover, problems around climate and climate change can be considered with respect to the ocean as the most inertial and accumulative element of the Earth climate system. Further, sea ice is a very important part of the cryosphere concerning the ocean, and we welcome papers on different aspects of sea ice studies.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
