Proceedings of the Black-footed Ferret & Prairie Dog Workshop, September 4-6, 1973
Both State and Federal agencies have been working with the black-footed ferret and prairie dog during the past few years. Much of the work is not extensive enough for publication in scientific journals and is, therefore, not reported. The objective of this Workshop was to bring workers together for discussion of the current status of the two species. Each of the Conservation Departments in the sta

Thermal characteristics of Lake Michigan, 1954-55
The thermal regime of Lake Michigan is described on the basis of the analysis of 1,671 bathythermograph casts made in 1954 and 1955. The beginning, duration, geographic extent, and ending of thermal stratification were determined from 51 thermal profiles from all areas of the open lake. The lake gained heat for about 5 months (mid-March to mid-August) and lost heat over the rest of the year. It wa

Seasonal variation of nitrogen, phosphorus, and chlorophyll a in Lake Michigan and Green Bay, 1965
Total and dissolved phosphorus, nitrate, and chlorophyll a were measured at four stations in northern Lake Michigan (inshore Michigan, offshore Michigan, offshore Wisconsin, and inshore Wisconsin) and one station in southern Green Bay during 16 sampling periods in 1965. The nutrients were measured at depths of 2, 5, and 10 meters and chlorophyll a at 2 meters. In Green Bay total phosphorus (33.7 p

Production of superheated steam from vapor-dominated geothermal reservoirs
Vapor-dominated geothermal systems such as Larderello, Italy, The Geysers, California, and Matsukawa, Japan yield dry or superheated steam when exploited. Models for these systems are examined along with production data and the thermodynamic properties of water, steam and rock. It is concluded that these systems initially consist of a water and steam filled reservoir, a water-saturated cap rock, a
