Sediment dispersal of the Yukon and Kuskokwim Rivers.
Description
United States Geological Survey, Menlo Park, California. Chief Scientist: Hans Nelson. Data (VanDornbottle, Secchidisc, grab) of field activity D-1-72-BS in Kuskokwim Bay, Bering Sea, Alaska from 08/30/1972 to 09/07/1972
Location
Kuskokwim Bay, Bering Sea, Alaska
Summary
Grab samples were collected with Van Dorn bottles and the filter handling and weighing procedure was after Winneberger, Austin and Klett (1963). The Kuskokwim data was synoptic; it was collected throughout the lower estuary from a helicopter on the day of the ERTS imagery. Kuskokwim and Yukon River sediment plumes were interpreted from multispectral scanner band 4 imagery of the Earth Resources Technology Satellite *ERTS-1), collected between the hours 1100-1200 Bering Standard Time during mid to late ebb tides, except for plume areas along the western shoreline of the Yukon subdelta where mid to late flood tides were occurring. ERTS imagery MSS band 5 for Kuskokwim River sediment plume was made on August 31, 1972, and MSS band 4 for Yukon River sediment plume was made on August 11, 1973. Grain-size composition of suspended and bottom sediments of the lower Kuskokwim River and upper Kuskokwim Bay was collected on August 30 and 31, 1972. Weight percent of the 0.62 mm size fraction by sieving at 0.062 mm for sand and at 2 mm for gravel. Visibility depths of 25 cm Secchi disc in lower Kuskokwim River and upper Kuskokwim Bay were made on August 30 and 31, 1972.
Info derived
Measurements of salinity and temperature, water turbidity, grain size and concentration of suspended sediment, and grain size of bottom sediment.
