Feasibility of a wave logger for freshwater nearshore applications / by Amanda Caskenette, Andrea Kneale, Sarah Glowa, and Eva C. Enders. : Fs97-6/3397E-PDF

"Wave action generates a wide variety of nearshore physical processes that contribute to acute behavioural and structural changes of nearshore ecosystems. Wave action is difficult to measure however, and most available devices are either expensive or inappropriate for short term deployments in shallow waters. A wave logger designed for shallow water use was deployed in Lake Winnipeg, Canada for five rounds at three sites to examine the ability of the wave logger to appropriately represent underwater forces. There was no relationship between wind speed and wave frequency. There was a significant positive relationship between wind speed and the 95% and mean instantaneous angle of displacement (IAD), which is a measure of force, dependent on site and wind direction. Deployments with a faster recording rate are needed to determine if the device can be used to measure wave frequency. The wave logger was useful when measuring the magnitude of underwater forces created by the waves and thus, there is potential for this device to quantify the role wave action plays in structuring nearshore communities"--Abstract, page vi.
