The dead zone case study answers
Dead Zones: VIMS Journal Articles | Virginia Institute of Marine Science
Dead zones are hypoxic low- oxygen areas in the world's oceans and large lakes. Once DO declines below 0. With such low concentration of DO, these bodies of water fail to support the aquatic life living there. However, in the s, oceanographers began noting increased instances and expanses of dead zones. These occur near inhabited coastlines , where aquatic life is most concentrated. In March , when the recently established UN Environment Programme published its first Global Environment Outlook Year Book GEO Year Book , it reported dead zones in the world's oceans where marine life could not be supported due to depleted oxygen levels. Some of these were as small as a square kilometre 0.
My house feels like a dead zone – a case study
A mal-operation case of busbar protection caused by a dead-zone protection abnormality in the Brazilian Midwest Grid on September 19th, , is briefly described. The operation process of pilot distance, automatic re-closure, busbar differential and dead-zone protection, and the emphasis on the logic scheme of dead-zone protection are analyzed. The differences in dead-zone protection logic between Brazil and China are discussed. A test platform was constructed in the laboratory, and a site simulated experiment was also performed. Possible causes are suggested and test activities are carried out to verify them.
A case study involving an integrated and sustainable research and management approach is focusing on Narragansett Bay in Rhode Island, including its watershed and air shed. Researchers are investigating how changes in nitrogen release into water bodies and climate impact watersheds and water quality. The research will be used to help restore and protect watersheds and highly valued water resources. Researchers are. The management approaches and computational tools developed based on this research will be adaptable for use in other threatened water systems across the country.
