Lakes Findley, Chester Morse and Sammamish, Washington, are characterized
by one major outburst of phytoplankton productivity and biomass (mainly
diatoms) with usually no or low fall activity. Vernal outbursts were
often delayed in the monomictic lakes by inadequate light because of
unfavorable climate and/or a lack of thermal stratification. Strong...
Lakes Findley, Chester Morse and Sammamish, Washington, are characterized
by one major outburst of phytoplankton productivity and biomass (mainly
diatoms) with usually no or low fall activity. Vernal outbursts were often
delayed in some lakes and years probably by unfavorable climate (snow cover
and cloudy rainy conditions). Mean spring-summer productivity...
Sample collection to define the phytoplankton biomass and productivity in Lakes Findley, Chester Morse, and Sammamish was conducted according to the schedule In Figure 1. Methods and procedures are the same as those
used in 1972 (Welch et al. 1972). The purpose of such sampling is to provide validation data...
Detailed mapping and geochemical analysis of Oligocene to early
Pliocene volcanic rocks in the Little Walker volcanic center, Mono
County, California have revealed a complex eruptive history. After
eruption of widespread rhyolitic ash flows of the Valley Springs
Formation in the Oligocene, Miocene to early Pliocene volcanism of
the western...
