Unusual Circulation Patterns and Inverted Thermocline in Lake Erie
High-resolution measurements obtained during the International Field Years on Lake Erie have shown that the layer of rapid temperature change in the lake (thermocline) is deeper offshore than at the coast due to large-scale wind variability and associated water circulation.
Dr. Ram Yerubandi in Environment Canada’s Water Science and Technology Directorate, is part of the binational team that made the discovery of the unusual thermocline and circulation patterns in Lake Erie. This finding describes the mechanism for the observed depressed thermocline, which is responsible for amplifying deep-water summer hypoxia and thus reducing the oxygen available to lake-bottom plants and animals.
The findings are published in Geophysical Research Letters. Since its publication, this research appeared prominently in newsletters such as American Geophysical Union Editors online spotlights and as an Eos research spotlight. A brief synopsis of this article was also published as notable research in the July issue of EARTH Magazine.
