Seasonal Characteristics of Two Saline Lakes in Washington

摘要: The limnology of two highly saline lakes in Washington was studied relation to the physical and chemical conditions which influence growth distribution phytoplankton. were sampled at frequent intervals for a period more than year 1950 1951. Morphometric determined, routine sampling included measurements temperature, transparency, oxygen, pH, alkalinity, phosphate, chlorophyll, quantitative samples Lake Lenore, less (T.D.S. 14 g/liter), is shallow unstratified during investigation. Dissolved nutrients high showed erratic variations summer. phytoplankton population taxonomically simple made up mainly species diatoms—Amphora sp. formed spring bloom, Chaetoceros elmorei late summer bloom. Soap relatively deep, meromictic, 35 g/liter). Temperature dichothermic, nutrient content high, especially monimolimnion. A winter maximum minimum observed population, change biota has been noted dilution lake recent years. Indication grazing by zooplankton found both lakes.
