Special Issue Information

Dear Colleagues,

Benthic biogeochemical cycling occurs in the benthic boundary layer and plays a critical role in regulating the fluxes of carbon and nutrients between the sediment and bottom water. This process involves the degradation and transformation of organic matter into inorganic nutrients and carbon, which benthic organisms facilitate through organic matter degradation. Understanding the biogeochemistry of sediments and the role of benthic organisms is central to this process.

It is important to consider the impact of human activities, such as coastal eutrophication and deep-sea mining, on benthic biogeochemical cycling. Research on this topic is essential to gain a comprehensive understanding of the biogeochemical processes involved, including the oxidation of organic matter, the cycling of nitrogen and phosphorus, and the production and consumption of various biogenic gases. In situ measurement methods are also used to study this process.

To provide a comprehensive overview of the current state of knowledge in this field, a Special Issue on “Benthic Biogeochemical Cycling of Ocean Nutrients and Carbon” will highlight the latest advances in our understanding of this topic. This Special Issue will serve as an essential resource for researchers and students interested in marine biogeochemistry, oceanography, and environmental science.

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.

This study assessed the impact of intensive human activities on organic matter (OM) and heavy metal cycles in Shihwa Lake, South Korea. Sediment oxygen demand (SOD), benthic nutrient flux (BNF), and benthic heavy metal flux were estimated using in situ benthic chambers. The combined analysis of sediment trap and SOD showed that the vertical supply of OM was a major controlling factor for benthic respiration. The BNF accounted for 35–144% and 32–184% of the N and P required, respectively, for primary production (PP) in the water column. The higher SOD may have also accelerated the release of Mn, Fe, Co, and Ni from the sediment. Benthic fluxes of Cr, As, Cd, Pb, Cu, and Zn were highest near the industrial complex, with ranges of 1.3 ± 0.9, 6.4 ± 4.9, 0.2 ± 0.1, 0.5 ± 0.4, 7.7 ± 1.4, and 452 ± 133 μmol m−2 d−1, respectively. Mn, Fe, Co, As, Pb, Ni, and Cu contributed more than 10% of the sediment to the current standing stock at Shihwa Lake. Full article
