Remote Sensing in Lake Superior Studies

An investigation was made of surface water transport in the extreme western arm of Lake Superior from July 25 to September 15, 1972. Temperature and water velocity profile measurements were made to determine the nature of currents at the tip of the lake. Bathythermographs and thermistor probes were used for these measurements. From the end of July to August 9, no pronounced steady stratification took place. A series of days with variable winds produced, under N.E. winds, warm water pileup at the tip of the lake, which was subsequently driven out by westerly winds. Some evidence of upwelling was indicated by cold surface waters near the shore. After August 9 considerable stratification with slight upwelling was noted.
