Elasmobranchs inhabiting depths beyond 200 m are extremely susceptible to overexploitation but are extracted by fisheries around the world either as target species or as bycatch. There is little information available to formulate management strategies to reduce elasmobranch-fishery interactions in the deep sea. In European Union waters, prohibiting...

This work presents a new high-resolution multibeam bathymetric map of a segment of active deep sea-floor spreading in the Atlantic Ocean, the northern Mid-Atlantic Ridge (MAR) at 45–46º N. New high-resolution bathymetry data were acquired using an Atlas multibeam echosounder onboard the research vessel Sarmiento de Gamboa during the EXPLOSEA-2 surv...

This work presents the preliminary result of the multidisciplinary cruise EXPLOSEA2 surveying the northern Mid-Atlantic Ridge and Azores Archipelago from 46° 30′ N to 38° 30′ N aboard the R/V Sarmiento de Gamboa and ROV Luso over 54 days (June 11 to July 27, 2019). In this cruise report, we detail the geophysical, hydrographic, geological, oceanogr...

Water quality models are in great demand to complement studies about the status of estuarine waters. However, local models do not perform well when boundary conditions are not properly defined and when biogeochemical processes are not described with adequate detail. This chapter presents advanced modeling applications to perform water quality studi...

The integration of multiple information layers from different regions in a common framework is particularly relevant when dealing with interregional and transnational pollution problems, very common in the Atlantic area. An integrated framework for the support of modeling fate and behaviour of oil and inert spills was designed in EASYCO, ARCOPOL an...

A new approach on bathing water quality management was given by the New Bathing Water Directive (NBWD), enforcing the implementation of alert and prediction systems in order to avoid bathers exposure to short-term pollution events. This paper focus the study of Portuguese bathing waters located in Estoril Coast, that can be exposed to short term po...

In the framework of the Lenvis project, a web service infrastructure able to provide professional users with field data and model results in real time was developed. One of the web services developed (web service model) executes a particle tracking model to simulate the dispersion of sewage discharges. This web service is comprised of a web client...

The new European Bathing Water Directive (2 006/7/EC) enforces "active management" of water quality instead of simple "monitoring" as in the previous Directive. Therefore, responsible authorities have an important task ahead to develop bathing water profiles, detect potential contamination sources, and forecast their impact on bathing water quality...
