PHYSICAL, CHEMICAL AND BIOLOGICAL CONDITIONS OF THE SAGAVANIRKTOK RIVER AND NEARBY CONTROL STREAMS, SHAVIOVIK AND CANNING RIVERS
Biological, physical and chemical data were collected from 28 stations on the Sagavanirktok River and five of its tributaries, the Canning River, Shaviovik River, two tundra lakes and Galbraith Lake. These stations are located on the North Slope of Alaska and in the area impacted by the oil industry...
