Abstract : Given a non-isothermal sounding, a lake is partitioned systematically into layers. The temperatures at their vertical midpoints are taken as representative for each layer. The hypsometric data are fitted to a simple power profile such that the actual and approximating basins have equal volumes. By the use of these simple functions, the integral which defines heat content is easily evaluated in cosed form. The two-layer method is tested on 46 open-season soundings for nine temperate North American lakes. The method lends itself readily to FORTRAN computer programming. (Author)
