Model Test and Hypothesis Examine how differences in Kh influence mid-lake estimates of whole-lake metabolism Hypothesis: At low Kh – mid-lake sensor = pelagic metabolism At high Kh – mid-lake sensor = whole-lake metabolism
Conclusions Over a range of likely mixing regimes, mid- lake sensors will detect a mixture of pelagic and whole-lake signals At some levels of mixing there will actually be an underestimate of even the pelagic signal Therefore there is a need to better understand the horizontal mixing regimes in small lakes
Further Study Examine how lake size influences the results Examine different ratios of pelagic-littoral metabolism Examine gas exchange affects
