An in-situ experiment on the effects of zooplankton grazing and nutrient regeneration on the phytoplankton of Yaquina Bay, Oregon

Creator:: Deason, Ellen Elizabeth
Abstract:: Natural populations of phytoplankton from Yaquina Bay, Oregon, were incubated in large polyethelene bags in- situ, with and without the natural assemblage of zooplankton. Samples were taken daily for two weeks in April, 1974. The biomass of phytoplankton in the bag without grazers reached values two to three times the...

Abstract:: The shallow water benthic habitat of the SW Beaufort Sea is frequently gouged by the keels of ice pressure ridges. This natural physical disturbance was hypothesized to be an important factor affecting the structure of the benthic community.

Prokaryotes associated with marine crust

Creator:: Mason, Olivia Underwood
Abstract:: Oceanic crust covers nearly 70% of the Earth's surface, of which, the upper, sediment layer is estimated to harbor substantial microbial biomass. Marine crust; however, extends several kilometers beyond this surficial layer, and includes the basalt and gabbro layers. In particular, the basalt layer has high permeabilities which allows for...
