Species specific phytoplankton production rates during a spring diatom bloom in Yaquina Bay, Oregon

Creator:

McMurray, Gregory R., 1925-

Abstract:

A simplified autoradiographic method for estimating species-specific phytoplankton production rates in mixed natural communities was evaluated in the laboratory and employed in the field. Laboratory experiments were designed to test the reliability and variability of the simplified method. Assays of ¹⁴C uptake by liquid scintillation spectrometry were used to evaluate...

Effects of micro-nutrients and major nutrients on the growth and species composition of natural phytoplankton populations

Creator:

Frey, Bruce E.

Abstract:

Large-volume (20-liter) bioassays were carried out in order to assess the effects of major nutrients and micro-nutrients on natural phytoplankton populations in water collected from a site close to the mouth of Yaquina Bay, Oregon. Seven long-term experiments were conducted during the years 1975-1976. A stripping technique employing activated carbon...
