Contents Notes
Temperature surveys were made across an east-west transect of Lake Superior during the 1973, 1974, 1975, and 1976 winter seasons and the 1976, 1977, 1978, and 1979 autumn seasons. A portable bathythermograph recorder measured water temperatures along the transect to a maximum depth of 200 m. There were 46 temperature surveys made, with an average of 24 temperature profile measurements per survey. This report presents tabulations of 39 of the 46 temperature surveys, along with isothermal contour charts portraying the thermal structure of the lake and station position charts showing the location of each temperature profile for all 46 surveys. Temperature tabulations from the 1973 and 1974 winters were published in a previous report.
