Western Stump Lake, a major canvasback staging area in eastern North Dakota
H.A. Kantrud
1986, Prairie Naturalist (18) 247-253
Large numbers of waterfowl, especially canvasback (Aythya valisineria), used Western Stump Lake as a staging area during most of October 1985. Selection of the lake as a conditioning site by this species likely is caused by extensive, shallow-water beds of sago pondweed (Potamogeton pectinatus) and lack of human disturbance. A...

Estimation of distributional parameters for censored trace level water quality data: 1. Estimation techniques
Robert J. Gilliom, Dennis R. Helsel
1986, Water Resources Research (22) 135-146
A recurring difficulty encountered in investigations of many metals and organic contaminants in ambient waters is that a substantial portion of water sample concentrations are below limits of detection established by analytical laboratories. Several methods were evaluated for estimating distributional parameters for such censored data sets using only uncensored observations....
Evaluation of gas data from high-temperature fumaroles at Mount St. Helens, 1980-1982
T.M. Gerlach, T. J. Casadevall
1986, Journal of Volcanology and Geothermal Research (28) 107-140
The Mount St. Helens fumarole gases show linear composition trends during periods of noneruptive degassing between September 1980 and October 1981. The trends are characterized by increasing H2O and decreasing CO2 and sulfur. Maximum fumarole temperatures also show a linear decrease during this period. High-temperature fumarole gases collected from the...
