Opis

"Polar Seas Oceanography" describes a new tool called the Generic Model System for simulations and assessment of potential radioactive spreading in the Arctic regions, through rivers, estuaries, regional seas and the Arctic and Atlantic basin. It considers the present and future potential for spreading of radionuclear pollution from sources, such as from the major Russian processing plants through Siberian rivers as well as from European sources such as the UK Sellafield plant. The book provides support for decision making involving risk prevention, forecasting and readiness for probable crises, alerting and detection, relief and mitigation and damage assessment. The book combines the expertise of professionals from the radionuclear and climate-change sciences.
