Seamless is a H2020 project aimed at improving the current European capability to simulate and predict the state of marine ecosystems. The project focuses on state indicators that are linked to the ocean “health” (e.g. to oxygenation, acidification, eutrophication), “services” (e.g. to sustainable aquaculture) and “response” to climate change (e.g. to the transfer of carbon in the ocean depths).

The 2nd edition of the Copernicus Marine Service Ocean State Report (OSR 2) published in 2018 provides information on changes and variations in the ocean over the past decades, with a focus on changes in the marine environment during the year 2016. It is written by nearly 100 scientific experts from more than 30 institutions and draws from the marine monitoring capabilities of the Copernicus Marine Service.

Cover: In Rosati et al. (, Rosati et al. found elevated concentrations of Hg and MeHg in the euxinic waters of the Black Sea.

By integrating observations from the GEOTRACES cruise and 1D biogoechemical modeling along the extended redox gradient of the Black Sea, the work highlights that the bulk of MeHg is produced in situ in anoxic sulfidic waters, and inputs from external sources (i.e. rivers, sediment and the Mediterranean Sea) are negligible.

In the frame of the continuous improvement strategy of the Copernicus Marine Service, OGS and LOV won a tender (issued by Mercator Ocean) that supports a 2-year project on leading Science and Technological development, aimed at ensuring the evolution of the service and being potentially implemented operationally within 3 years.
Mediterranean and Baltic Seas are somehow two different worlds in term of biogeochemical dynamics, but some challenges they face are common, especially those related to toxic pollutants and harmful algal blooms that may affect ecosystem, aquaculture and tourism. Toxicity can be linked to algal blooms, which are operationally monitored by different research teams, usually by ships. Satellites may instead provide a more informative synoptic view, that can be also assimilated by the forecast modelling systems, as that one managed by OGS within the CMEMS-MED-MFC.
