Interests: Roberta’s research interests focus on coastal ocean pollution, the coastal ocean carbon cycle, the occurrence and deposition of legacy and emerging contaminants in sediments, sediment geochemistry and Pb-210 dating. Her current projects are the EU COST action Ocean Governance for Sustainability (OceanGov) Working Group on ‘Ocean acidification and climate change’, and the EU Interreg AdriaClim on ‘Climate change information, monitoring and management tools for adaptation’.
Interests: Ana Carolina studies the sedimentary environment to evaluate the temporal trends of Global Change, by using Pb-210 dating and sediment geochemistry. Her current projects are related to blue carbon fluxes and stocks in the Mexican coastal zone, and the impact of contamination (trace elements, microplastics, POPs) and recent climate change on diverse aquatic ecosystems around the world.
Interests: Federico’s research interests are as follows: geology and environmental geochemistry, especially for carbon and biogenic flux analyses as proxies of primary production in the euphotic layer of the oceans and to the reconstruction of the late Holocenic climatic cycles. Geochemical studies of the marine particles in the water column and the processes of bottom sediment/water interaction. The use of environmental and paleoenvironmental proxies: total organic carbon, nitrogen biogenic silica and biogenic barium, and other trace metals (F, Al and Mn), radioisotopes (230Th, 234-238U, 10Be, 14C e 210Pb), stable isotopes (δ18O, δ13C e δ15N) and sedimentological characteristics of the sediment. Determination of the accumulation rate in the bottom sediments for time scales ranging from under years to thousand under years.
Interests: Stefano’s research interests are as follows: Sedimentology, biogeochemistry and dynamics of marine sediments and particles. Flux and mass balance calculations for carbon, as well as biogenic and terrigenous constituents, to understand the origins, transport pathways and fates of particles on continental margins. The study of organic matter in the sediment and of nutrient fluxes at the water–sediment interface. His current research interests are: (a) the vertical fluxes of particles and lateral transportation of materials from the continental shelf to deep basins in Arctic and Mediterranean Sea; (b) non-destructive core logging/scanning methods, including XRF Core Scanning.
Special Issue Information
Dear Colleagues,
Over the last few centuries, the environmental quality of coastal and marine ecosystems underwent a dramatic degradation driven by human activities and climate change. Anthropogenic impacts on these areas have multiple sources, including land use change, direct inputs and surface runoff of contaminated waters from human settlements and industrial facilities, leading to environmental problems such as the physical alteration and destruction of habitats, chemical contamination, eutrophication, deoxygenation and climate change.
Efforts to identify the sources and consequences of the increasing human-induced pressure on these highly sensitive environments have received a great deal of attention in recent decades. Bottom sediments, essential, integral, and dynamic parts of the coastal and marine ecosystem, can act as sinks for several chemicals compounds, and also as potential long-term secondary sources of anthropogenic contaminants.
Sediment cores are useful archives to reconstruct the history and trends of environmental changes in coastal and marine areas all over the world. Sedimentary records of geochemical elements, legacy and emerging compounds, biomarkers, and other indicators have made possible the study of background and post-industrial revolution conditions in the marine realm. If the sources and trends are identified, scientific information can guide management practices to control, or even reverse, the detrimental impacts on these ecosystems.

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. 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.
