Vertical Distribution of Benthic Foraminifera within Sediments (Preliminary Report)

Benthic foraminifera distribution in high polluted sediments from Niterói Harbor (Guanabara Bay), Rio de Janeiro, Brazil.

Dockyards and harbors are recognized as being important locations where sediment-associated pollutants can accumulate, which constitutes an environmental risk to aquatic life due to potential uptake and accumulation of heavy metals in the biota. The aim of this paper is to assess the concentrations and the effects of some heavy metals in the benthic foraminifera assemblage in Niterói Harbor. Lo...

Distribution, Diversity and Abundance of Benthic Foraminifera of the Northwstern Persian Gulf

During ROPME Winter Cruise 2006, twenty six surface sediment samples taken from the Northwestern part of the Persian Gulf at depths of 13-77m were analyzed for their foraminifera content. A total of 93 species of benthic foraminifera were found in the study area. The foraminifera assemblages were dominated by Ammonia beccarii, Spiroloculina excavata, S. depressa, Quinqueloculina dimidiata,...

Systematic Paleontology, Distribution and Abundance of Cenozoic Benthic Foraminifera from Kish Island, Persian Gulf, Iran

Abstract Foraminifera are one of the most important fossil microorganisms in the Persian Gulf. During micropaleontological investigations in 5 sampling stations around the Kish Island, 14 genera and 15 species of dead Cenozoic benthic foraminifera were determined and described. Next to these assemblages, other organisms, such as microgastropods and spines of echinids were also looked into. In ...

Ba incorporation in benthic foraminifera

Barium (Ba) incorporated in the calcite of many foraminiferal species is proportional to the concentration of Ba in seawater. Since the open ocean concentration of Ba closely follows seawater alkalinity, foraminiferal Ba /Ca can be used to reconstruct the latter. Alternatively, Ba /Ca from foraminiferal shells can also be used to reconstruct salinity in coastal settings in which seawater Ba con...
