    Introduction to Part II: National Case Studies

    No full text
    This book (Part II of a volume on “Oil Pollution in the Mediterranean Sea”) presents a review of knowledge on oil pollution in the Mediterranean Sea, through a series of national and regional case studies. Making use of a range of data on oil extraction and production activities, oil transportation, satellite technology, aerial surveillance, in situ monitoring, oil spill sampling and oil fingerprinting, for example, it presents a picture of trends in oil pollution in various areas of the region over many years. It examines national practices in a number of Mediterranean Sea states. A range of legislative measures are in place to protect the marine environment of the region. For example, the Mediterranean Sea and its various regions, such as the Adriatic Sea, have Special Status for the prevention of pollution by oil from ships under the International Convention for the Prevention of Pollution from Ships and its Protocols (MARPOL 73/78 Convention). At the same time, the Convention for the Protection of the Mediterranean Sea Against Pollution (Barcelona Convention, 1976) and its various protocols provide a legislative framework under which countries in the region can work together to cooperate in preventing pollution from ships, for example, and work together to combat pollution in the event of an emergency. National contingency planning and oil pollution preparedness and response activities and the work of the Regional Marine Pollution Emergency Centre (REMPEC) for the Barcelona Convention’s contracting parties are also discussed within various national case studies. This book brings together the work of scientists, legal and policy experts, academic researchers and specialists in various fields relating to marine environmental protection, satellite monitoring, oil pollution and the Mediterranean Sea

    Introduction to Part I: The International Context

    This book (Part 1 of a volume on Oil Pollution in the Mediterranean Sea) presents a review of knowledge on oil pollution in the Mediterranean Sea, through a series of chapters at an international level. The chapters consider various sources of oil entering the marine environment, activities such as numerical modeling of oil pollution in the Eastern and Western Mediterranean Basins, oil spill beaching probability assessment, and oil spill intervention activities. They also examine legislative measures in place to protect the marine environment of the Mediterranean from oil pollution, including the role of the Convention for the Protection of the Mediterranean Sea Against Pollution (Barcelona Convention, 1976) and its various protocols, in providing a framework under which nations across the region can work together to cooperate in preventing pollution from ships and from offshore exploration and exploitation activities or in the event of an emergency. The work of the Regional Marine Pollution Emergency Response Centre for the Mediterranean Sea (REMPEC), established under the Barcelona Convention to enhance collaboration and cooperation between national contracting parties, is also examined, including its role in national contingency planning and oil pollution preparedness and response activities. The International Maritime Organization has a role in protecting the Mediterranean Sea and its various regions through the International Convention for the Prevention of Pollution from Ships and its Protocols (MARPOL 73/78 Convention) and sets limits on discharges of oil from ships, while the European Maritime Safety Agency supports oil spill detection activities through satellite surveillance across the region. This book brings together the work of scientists, legal and policy experts, academic researchers and specialists in various fields relating to marine environmental protection, satellite monitoring, oil pollution, and the Mediterranean Sea

    History, Sources and Volumes of Oil Pollution in the Mediterranean Sea

    No full text
    This chapter presents a brief review of history, sources and volumes of oil pollu-tion in the Mediterranean Sea. Historical records show 16 major oil spills oc-curred between May 1966 and September 2017, and resulted in oil spills ranging between 6,000 and 144,000 tonnes; the largest spill came from the MT Haven tanker after an explosion on board on April 11, 1991. Sources of oil pollution are typical for other seas and include shipping, oil and gas platforms, ports and oil terminals, land-based sources, military conflicts, natural oil seeps, and even at-mospheric inputs. Shipping activities are the main cause for oil pollution in the Mediterranean Sea because oil and gas production and exploration is not so im-portant, unlike in the Gulf of Mexico or the Caspian Sea. If we exclude major oil spill accidents from ships, which are very rare events in the Mediterranean, dif-ferent expert reports and estimates provide total volumes of oil pollution ranging from 1,600 to 1,000,000 tonnes per year. The 625 times difference in values means that we still do not know the real volume of oil pollution entering the Mediterranean Sea and this is a big problem that should be addressed

    A model for production, perception, and acquisition of actions in face-to-face communication

    No full text
    The concept of action as basic motor control unit for goal-directed movement behavior has been used primarily for private or non-communicative actions like walking, reaching, or grasping. In this paper literature is reviewed indicating that this concept can also be used in all domains of face-to-face communication like speech, co-verbal facial expression, and co-verbal gesturing. Three domain-specific types of actions, i.e. speech actions, facial actions and hand-arm actions are defined in this paper and a model is proposed that elucidates the underlying biological mechanisms of action production, action perception, and action acqui¬sition in all domains of face-to-face communication. This model can be used as basic concept for embodied conversational agents and thus for specific human-computer interaction technologies
