Abstract
In July 1977 the Great Lakes Environmental Research Laboratory installed a lightweight, solar powered research tower in Lake Michigan. The tower, located 2 km offshore from Muskegon, Michigan, in 16 m of water, provided a stable platform for two levels of anemometers and air temperature sensors, a surface water temperature sensor, and an array of four wave staffs to measure meteorological and directional wave variables. Solar power was successfully used to provide power for tower instrumentation. The measurements, while short-lived due to a guy wire failure in October 1977, comprise over 1300 well-documented hourly wind and wave data for further detailed studies. This report presents a detailed description of the instrumentation, data collection, and data reduction systems. The results show that the triangular array of wave staffs provides reasonable wave direction information, although nearshore waves appear to have a larger onshore component of momentum than would be indicated by prevailing winds. Further detailed studies of wind and wave processes are in progress.
