The OMG RG has multidisciplinary expertise in monitoring and numerical modelling of the physical and geological processes of the coastal and deep sea, addressing environmental problems in the perspective of climate change impacts and societal needs. The main research activities are focused on research and forecasting of hydrodynamic processes at different scales, from the large scale (N Atlantic), to coastal (Upwelling Iberian ecosystem) and small scale (estuaries and shoreline) systems. Key problems addressed comprise the understanding of the mechanisms of open ocean and coastal circulation with emphasis on the links between these two, problems of larval dispersion and connectivity. Extensive studies of estuarine systems along the Iberian coast are being carried out, including physical-biology interactions, the development of innovative monitoring and advanced modelling of systems for coastal environmental sustainability assessment. Observations and modelling of gravity waves and sediment transport are developed in close connection with the morphodynamics of the near shore. Additionally, OMG RG conducts research on coastal and deep sea geological processes, mineral and energy resources, hazards, and their impacts on ecosystems and populations. Research on geological hazards is focused on coastal erosion and shoreline retreat, and the characterisation of areas of high seismic risk. Research on marine mineral and energy resources includes sand and gravel in the continental shelf, Co-rich polymetallic crusts and nodules, hydrocarbons (oil gas and gas hydrates), and assessment of impacts of offshore exploitation/dredging activities.
