Characterization of Organic Matter in Marine and Freshwater Environment

Dear Colleagues,

Organic matter in marine and freshwater environments has a complex chemical composition and physico-chemical properties that depend on its source, interactions, and possibilities for biogeochemical transformation and preservation. The influence of the living world, from the smallest phytoplankton and microbes to larger zooplankton, as well as the geology of the aquatic system are crucial to understanding the role of organic matter in water and the possible role of oceans, seas, and lakes in carbon sequestration. Organic molecules play a role in the distribution of carbon by influencing the global carbon cycle and the associated climate changes. On the other hand, organic matter changes when exposed to different types of environmental stressors, such as changes in temperature, pH, and salinity, anthropogenic pollution, and atmospheric contributions. Changes in organic matter in waters have an impact on other chemical components of water and thus indirectly affect water quality. Qualitative and quantitative characterization of heterogeneous natural organic matter remains a major challenge for chemists and oceanographers around the world and requires the development of new separation methods and highly sensitive analytical methods.

The aim of this Special Issue is to publish high-quality original research papers and review articles addressing recent advances in the characterization of global or local natural organic matter, the use of new methods, and/or developments in monitoring.

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 250 words) can be sent to the Editorial Office for assessment.

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. Water is an international peer-reviewed open access semimonthly 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.
