The relevance of perfluoroalkyl substances (PFASs) fluxes to the deep sea and the role of deep continental margins and basins as their ultimate sink is assessed.The presence of PFASs in particles sinking to the deep northwestern Mediterranean Sea confirms the role of the latter as ballast for the transfer of pollutants to the deep sea.

Increased biogeochemical monitoring is an identified and pressing current need. Under PERSEUS new sensors were added to moorings and new bio-Argo floats as well as Continuous Plankton Recorder (CPR) monitoring initiated. This upgrade of the selected observatories in the SES is absolutely essential to improve the estimates of current ocean states and constrain model predictions, thus contributing to the proper implementation of GES as required by the MSFD.

Five months after the formation of a massive dense water on the continental shelf and in the deep basin of the Gulf of Lions the water of coastal origin created a distinct bottom layer up to a few hundreds of meters thick over the central part of the NW Mediterranean basin, which was overlaid by a layer of newly formed deep water produced by open-sea convection. These new observations highlight the role of intense episodes of both dense shelf water cascading and open-sea convection to the progressive modification of the NW Mediterranean deep waters.

This is an important area that is historically and chronically under-sampled; in conjunction with the JERICO TNA program 2 proto glider endurance lines were undertaken. This knowledge output contributes to the development of a glider network in the Southern European Seas (SES), to assess a wide range of scales of variability in the upper 1000m of the ocean, and allow accurate estimates (without aliasing effects due to mesoscale processes) of water transport and characterisation of the physical and biogeochemical properties of the surface and intermediate water masses.

Southern European Seas (SES) are analyzed for gaps on data and knowledge related to a list of key processes, pressures, and impacts. The Mediterranean Sea's hydrometeorological variability is well-described using a combination of existing databases and models; the availability and update of long time-series is stressed. Some of the gaps that have been found are; poor understanding of the Strait of Gibraltar's biogeochemistry, there is a complete lack of information for marine litter and noise there is a clear gap in the estimates of fluxes of N, P, and pollutants to the sea.

The abundance, spatial distribution and qualitative composition, of benthic marine litter, were investigated in five study areas from the Eastern Mediterranean and Black Seas. The size distribution of litter items showed that ?50% fall into medium size categories (10x10 cm, 20x20 cm) along with an elevated percentage of small-sized (<5x 5 cm) plastic litter items. The comparative analysis of the data highlighted the dependence of the marine litter problem on many local factors (human sources and oceanographic conditions) and the urgent need for specificactions.

Moreover a comparative assessment of the Initial Assessments of five Southern European Seas (SES) countries has been also independently is performed. The comparison between meta-analysis results and initial assesment shows similarities for coastal areas only. Major knowledge gaps have been detected for the biodiversity, marine food web, marine litter and underwater noise descriptors. The meta-analysis also allowed the identification of additional research themes targeting research topics that are requested to the achievement of GES.

Similar studies have been made for coastal areas and open waters of the Mediterranean and the Black Sea. This report presents the results of the economic and social analysis of the human activities which are exerting pressures on open waters of the Mediterranean and the Black Sea. The analysis has been done using existing available data on main marine activities such as fisheries, maritime transport, submarine cable and pipeline operations and marine hydrocarbon extraction. It makes the same analysis on marine coastal ecosystems of the Mediterranean and the Black Sea taking into account the main marine sectors such as fisheries and aquaculture, maritime transport and ports, recreational activities and coastal tourism, submarine cable and pipeline operations and marine hydrocarbon (oil and gas) extraction as well as on the main land-based activities impacting the coastal marine. The gap analysis in both open and coastal waters has shown that a significant part of required data to perform the economic and social assesment of human pressures assessments are missing or not publicly available, especially those needed to assess value added and employment wages as well as cost of degradation.

The hydrology of the Cretan Sea is studied by using T/S (temperature salinity) profile data derived from the first Argo float deployed in the area over a 2 year period (2010-2012) which was combined with time series data recorded from the POSEIDON E1-M3A multi-parametric instrumentation platform. The acquired datasets were enriched with available CTD (conductivity, temperature, depth) profiles taken on the mooring site during cruise maintenance surveys. The combined research activities resulted in a large dataset of physical properties allowing extended geographical coverage and an in-depth analysis of the Cretan Sea dynamics during the 2-year period.

Result description

An extensive analysis based on the joint signals provided by available historical fisheries records and data from remote sensors for surface currents, kinetic energy (KE), temperature and chlorophyll is performed. Based on this analysis, it is concluded that anchovy recruitment in the Alboran Sea is highly linked to the dynamics of the Atlantic Jet and the associated circulation features in the basin.

The oceanographic information management system provides user-friendly and fast access to physical, geochemical and biological data of the Mediterranean and Black Seas’ ecosystems. The database includes both data collected by PERSEUS (100 cruises or 8,000 CTD casts) and previous European projects such as SESAME, MyOcean, SeaDataNet and EMODnet. The database contains data for almost 8,000 cruises since December 2015. About 98% of the data is freely available to any user after online registration. Other data can be obtained through negotiation with data provider. (Data are held at http://isramar.ocean.org.il/perseus_data/)

The Adaptive Marine Policy Toolbox has been especially developed to assist policy makers to develop measures in order to achieve or maintain Good Environmental Status (GES) of costal and marine ecosystems in the Mediterranean and Black Sea basins. The purpose is to organize relevant scientific findings and resources into a user-friendly format to aid the decision-making process, thus saving time and frustration.

The role of Mixed Layer Depth (MLD) variations in shaping the phytoplankton phenology was explored in the Mediterranean Sea, a basin displaying contrasting phenological regimes. A database of MLD estimations was merged with ocean color chlorophyll concentrations to generate concomitant annual MLD and color chlorophyll concentration cycles. Several indices such as annual maximum of MLD and satellite surface chlorophyll-a concentrations were calculated to quantitatively analyze these cycles. It was found that two dominant phenological regimes coexist in the Mediterranean Sea. The first is marked by a typical spring bloom, as in temperate regions. The second displays a low seasonality and an absence of an intense satellite surface chlorophyll-a concentrations peak as in subtropical areas.

First indications of contaminant levels in deep sediment of different regions of the Mediterranean show they decrease rapidly when the distance increase from point sources; however, a large amount of coastal inputs is exported offshore. Attention should be paid to the fate and the impact of new emerging pollutants. At the basin scale, contaminant concentrations in biota show very different patterns depending on substances. For some substances, the biogeochemical background and the environmental conditions play a important role in the contamination of marine organisms.
