A Comparative Study in Eutrophication

Linsley Pond, a small body of water, 14 m deep located in North Branford, Connecticut, has been the subject of investigation for some 30 years. Over the past years, like many lakes, it has suffered from steadily increasing pollution. During the year August, 1965, through August, 1966, the entire water column of 14 m was sampled weekly and temperature and oxygen data were simultaneously monitored, with the idea in mind of making as complete a geochemical study as possible of all detectable elements in the water and how they move in a thermally stratified lake.
