Purpose
|
|
Sediment dispersal of the Yukon and Kuskokwim Rivers.
|
|
|
Information to be Derived
|
|
Measurements of salinity and temperature, water turbidity, grain size
|
|
and concentration of suspended sediment, and grain size of bottom sediment.
|
|
|
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 fractions was
|
|
determined by the hydrophotometer method of Jordan, Freyer, and Hermen (1971)
|
|
and 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.
