Stratification, Currents, and Upwelling in Lake Ontario, Summer 1982

Abstract

A description is presented of physical measurements carried out on Lake Ontario during the summer of 1982. Seasonal variations of stratification and circulation are illustrated by monthly averages of temperature and current distributions in a north–south cross section of the lake. Day-to-day variations of temperature and currents are presented for three periods coinciding with biochemical investigations along the same transect of the lake. A wind-induced upwelling event followed by alongshore propagation of a warmwater wave is described and the dynamics involved are discussed.
