Okpoka Creek of the Upper Bonny Estuary in the Niger Delta is a tidal creek receiving organic anthropogenic effluents from its environs. The study investigated the influence of tides (low and high) on the species composition, diversity, abundance, and distribution of phytoplankton. The surface water and phytoplankton samples were collected monthly from May to April at both tides from Cited by: 8. Introduction Recent studies on the Gulf of California have shown it to be a very productive area having a considerable diversity of species (Alvarez-Borrego , AlvarezBorrego and Lara-Lara ). There have been numerous works on phytoplankton of the Gulf of California, especially devoted to planktonic diatoms and dinoflagellates (a review was provided by HernandezBecerril ). Regarding. Analysis of diatoms, pollen, and the carbon-isotopic composition of a sediment core from a brackish marsh in the northern part of the San Francisco Estuary has provided a paleosalinity record that covers the past yr. Changes in marsh composition and diatom frequencies are assumed to represent variations in freshwater in-ﬂow to the estuary. using planktonic foraminiferal biostratigraphy, microfacies analysis, and sequence stratigraphy. An, 29 m outcrop consisting of limestone and marl was measured, and four planktonic foraminiferal biozones were identified spanning the boundary. Planktonic foraminiferal extinction across the K/Pg boundary was catastrophic and Size: 4MB.

THE DISTRIBUTION OF EPIPHYTIC DIATOMS IN YAQUINA ESTUARY, OREGON INTRODUCTION Estuaries are characterized by water with a salinity range vary-ing between that of sea water and that of freshwater.
Tidal exchange freshwater inflow contribute to this salinity variation as well as to the turbulence which mixes the water mass (Hedgpeth, ), and.

In a series of papers, Cooper has documented the diatom community structure changes in relation to land-use changes over approximately the past 2, years (Cooper, ; Cooper, a; Cooper.
Diatoms are a major group of algae, and are one of the most common types of phytoplankton. Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water by: 2.
Hence, planktonic centric diatoms were selected as a possible biomonitoring tool. This study reports the findings of a year-long study which examined patterns of diatom (Chaetoceros, Ditylum, Rhizosolenia, Coscinodiscus, Guinardia, Dactyliosolen, Odontella and Lithodesmium) succession in Offatts Bayou, an embayment of Galveston Bay, Texas (Fig.

The literature was examined to relate ambient silica concentrations to numerical dominance of specific freshwater planktonic diatoms. Mean silica concentrations (mg/liter) during dominance are: Stephanodiscus astraea, ; Tabellaria flocculosa asterionelloides, ; Asterionella formosa, ; Melosira granulata, The concentration at time of dominance and patterns of diatom periodicity Cited by: The abundance, distribution, and diversity of ichthyoplankton in the Puget Sound estuary and San Juan Islands during early spring Adam J.
