Characterization of organic matter quality and content in Columbia River suspended particulate matter by cupric oxide oxidation

Creator:

Alleau, Yvan M.

Abstract:

The organic content of the Columbia River suspended particulate matter (SPM) results from the input of autochthonous (phytoplankton) and allochthonous (terrestrial vascular plants) production. The contribution of these two sources appears seasonal and responds to factors such as rainfall, runoff, river flow, light and nutrients availability. While numerous studies have...

An examination of the form and variability of manganese oxide in Columbia River suspended material

Creator:

Covert, Paul Allister

Abstract:

Suspended particulate matter (SPM) in the Columbia River is a mixture of particles of several origins having varying physical and biogeochemical properties. The relative abundances of these freshwater particles changes with season and apparently also with tide. Prior investigation has quantified seasonal variation of organic material in both the Columbia...
