| Abstract | Zooplankton tows and hydrographic observations were made in to bays on the Oregon coast. Five stations were sampled weekly in Yaquina Bay from May, 1969 through September, 1970. Three stations were sampled weekly weekly in Netarts Bay from October, 1969 through January, 1961. Zooplankton collections were made with a Clarke-Bumpus sampler towed in a series of oblique steps. A #6 mesh (.239 mm aperture) net was used. A one year period from October, 1969 through September, 1970 was used to make a comparison of location and succession of zooplankton populations in the two bays... (from the Abstract) |
| Notes | The "two dissimilar marine embayments" were Yaquina and Netarts Bays. Sampled zooplankton weekly in Netarts Bay from Oct.1969-Jan.1971 and compared results with samples from Yaquina Bay from May 1969-Sept.1970. Discusses differences in populations between the bays. "During the summer when upwelling caused higher food availability animal numbers were very high in both bays. The bulk of these numbers were contributed by a small number of species and summer diversity was low. During the winter diversity increased as new species were carried into Oregon waters from the south by the Davidson current. Numbers of animals in all categories were low during the winter." (from the Abstract) Major professor was H. F. Frolander. |
