Zach Writes News Column on Lake Effects of Early Spring

Zach Wood has started writing a public interest column on aquatic ecology and other themes for the Bangor Daily News!  Check out his first article on implications of this year’s early spring for Maine’s lakes.  In this article Zach explains how an early spring can change lake dynamics by causing longer and stronger lake stratification. During stratification, a lake divides into two layers, an upper (warm) and lower (cold) layer, with the latter being essentially sealed off from the atmosphere. Developing anoxia in the lower layer can release phosphorus from the lake bottom, which eventually can mix throughout the entire lake leading to algae blooms and lowered water quality.
