Abstract

Dissolved oxygen concentrations in a lake are integral to its ecosystem as they control biogeochemical functions. Our lab has found that a Hudson valley lake, Minnewaska, has been oscillating between low and high levels of dissolved oxygen at its bottom for at least the past 5 years. This is significantly different from two nearby lakes: one, Awosting, that always has high oxygen at the bottom of the lake; another Mohonk, that typically goes anoxic at the bottom of the lake each summer. These fluctuations of oxygen concentrations coupled with the nearby comparison lakes have posed a unique opportunity to observe how hypoxia and anoxia spatially affect the nutrient concentrations in Minnewaska.
