Response to ultraviolet (UV-B) radiation by attached assemblages of estuarine diatoms

Creator:

Brooker, Deborah L.

Abstract:

Global atmospheric pollution from chlorofluorocarbons has the potential of causing significant reductions in the concentrations of stratospheric ozone. If the production of chlorofluorocarbons were to continue into the future at the rate prevalent in 1977, the steady state reduction in total global ozone could be between five percent to ten...

effort to measure the effect of UV-B radiation on the colonization of new substrates by benthic diatoms
Response of estuarine diatom assemblages to ultraviolet-B radiation (290-320 nm)

Creator:

Brooker, Deborah L., Worrest, Robert C.,, and Oregon State University

Abstract:

Artificial substrates colonized by diatoms from Yaquina Estuary, Oregon, were exposed to solar visible radiation and three levels of ultraviolet radiation (UV-B, 290-320 nm). Flow-through microcosms were constructed inside a glasshouse to serve as chambers for the artificial substrates. The artificial substrates were sampled during three spring/summer experiments. Chlorophyll a...
