Limnological Methods

The purpose of this volume is to present the essentials of those basic methods necessary for (a) entry into the subject of limnology, (b) limnological surveys of lakes and streams, and (c) fundamental information upon which specialized researches depend. No attempt is made to assemble all of the different methods in current use. The writer has deliberately selected certain of those which, for the most part, long have been used in his field and laboratory programs and which provide, when properly used, satisfactory results.
