A critical comparison of methods for the determination of phytoplankton chlorophyll

Creator:

Salinas, John T.

Abstract:

The concentration of chlorophyll in natural bodies of water is commonly determined as a means to rapidly estimate the phytoplankton biomass. The literature gives numerous warnings, however, as to the problems involved with accurately determining chlorophyll concentrations. The author's work at Crater Lake, Oregon enticed him to explore critically the...

Phytoplankton in Upper Willamette Reservoirs Dataset

Creator:

Murphy, Christina A., Pollock, Amanda M. M., Arismendi, Ivan, and Johnson, Sherri L.

Abstract:

Phytoplankton samples were collected from 5 upper Willamette Basin reservoirs in variable months during years 2013-2016 and 2019. Samples were collected from Blue River Reservoir, Cougar Reservoir, Fall Creek Reservoir, Lookout Point Reservoir, and Hills Creek Reservoir. The phytoplankton were identified and enumerated by Jim Sweet at Aquatic Analysts. Density...

Metabolism of periphyton communities in two small streams

Creator:

Lane, Charles Bertell

Abstract:

A technique for estimating gross primary production and respiration of periphyton communities, in situ, in small turbulent streams was developed using a photosynthesis-respiration chamber in a modified "light and dark bottle" method. Trays containing portions of the substrate bearing the benthic community were embedded in the stream, level with the...
