1982年6月至1983年7月，在密歇根湖安装了15个系泊装置，在15米和50米深度处安装了流速计。6个系泊围绕南部盆地约75平方英尺，6个紧密间隔的系泊横贯湖中脊和邻近的山谷，3个系泊占据南部和北部盆地的中心。在盆地南部，月平均海流在6月和7月为弱反气旋，其余时间为气旋，3月最强。温度和每日平均电流都显示出最严重（4&y周期）涡型振荡的影响。季节性温跃层在1983年（6月初）比1982年（8月中旬）建立得更早。
An array of 15 moorings, supporting current meters at 15 and 50 m depth, was in place in Lake Michigan from June 1982 to July 1983. Six moorings surrounded the southern basin on about the 75 m&bath, six closely spaced moorings transected the mid-lake ridge and adjacent valley, and three moorings occupied the centers of the southern and northern basins. In the southern basin, monthly-averaged currents are weakly anticyclonic during June and July, cyclonic during the rest of the year, and most intense during March. Temperatures and bidaily-averaged currents both show the effects of the gravest (4&y period) vortex-mode oscillation. Also, it is shown that the seasonal thermocline became well established much earlier in 1983 (early June) than in 1982 (middle August).
