Extreme Wave Climate
                           Characterization, Forecast, and Warning
        The Apostle Islands lakeshore in Lake Superior is a world-class destination for sea kayaking, luring paddlers with scenic wilderness, ancient geology and a rich cultural history. Some of the most popular attractions are the sea caves located at several spots around the archipelago. The water environment in the Apostle Islands is undoubtedly quite complex and dynamic due to the interactions of winds, currents, and the surrounding 22 islands at the site. Waves generated in Lake Superior can diffract and reflect when they encounter the islands and may combine to form extreme waves in a process known as geometric focusing. This process is applied to determine local regions of energetic wave fields for use in wave power generation around the world. In addition, significant energy and momentum transfers can occur during the wave and current interaction, yielding extreme waves that can affect the navigation and kayakers' safety. To date information of wave climate in Lake Superior is very little. Currently we are developing an in-situ Real-Time Wave Observation System (RTWOS) that can be accessed through any portable wireless device. Furthermore a real-time INFOS-Apostle is currently developed to provide real-time wave climate in the Apostle Islands. Outreach efforts (see Wisconsin State Journal Article has been continuously paid to address the community and society needs. An energy efficient push button Real-Time Wave Kiosk System (RTWKS) is also designed, built, and installed at the Meyers Beach, WI, where most kayakers/boaters enter water in Lake Superior.  The benefit of providing certain conditions in favor of the occurrence of dangerous extreme waves/freak waves is critical for the warning kayakers and boaters in Great Lakes. Recent articles related to the freak waves and RTWOS can be found at UWMadScience and Sea Grant News.
