Impact/Purpose:
During the 2015 Lake Michigan CSMI effort we collected continuous undulating tow and autonomous glider data including conductivity, temperature, depth, fluorescence, and backscatter across the northern half of Lake Michigan. During the same period, we also collected discreet vertical water column profiles from our research vessel the Lake Explorer II at point locations spread along four spatially coincident transects. Although the discreet vertical profiles are informative we found the continuously collected data to be much more informative especially in terms of identifying wind and weather related upwelling’s, and their effect on lake thermal stratification. For this reason we developed visualization techniques for continuously collected data like that collected by the autonomous glider and our towing efforts. This information and graphics will likely be used by Indiana-Illinois SeaGrant to “tell the story” of the 2015 Lake Mi CSMI and the data collected. Further developing and refining these types of data visualizations will be important as we collect more and more types of continuously collected data.

Although the discreet vertical profiles are informative we found the continuously collected data to be much more informative especially in terms of identifying wind and weather related upwelling’s, and their effect on lake thermal stratification. We’ll discuss comparisons among the discreet and continuous water column profiles and the perspectives gained from each type of data.
