“…Characteristic species found in this interval include C. oolina, F. wuellerstorfi, Uvigerina sp., Gyroidinoides sp., and Globocassidulina subglobosa, together with a diverse group of elongated foraminifers belonging to genera such as Stilostomella, Plectofrondicularia, Pleurostomella, Siphonodosaria, and Crysalogonium. The presence of species that occupy a wide microhabitat range (F. wuellerstorfi, C. pachyderma, and C. oolina) might suggest a bathyal environment with low to moderate flux of organic carbon and suboxic to anoxic conditions present at the time the deeper sediment layers were deposited (Gooday and Rathburn, 1999;Corliss, 1985).…”

“…Benthic foraminifera are shellproducing meiofauna in marine sediments. They inhabit a variety of subenvironments within the sediments under higher flux of organic carbon [Corliss, 1985;Gooday, 1986;Bernhard, 1992;Loubere et al, 1993]. However, in environments where food availability is limited, they tend to concentrate in the surface layers of the sediments.…”

Abstract. We present a quantitative method, based on the relative abundances of benthic foraminifera in deep-sea sediments, for estimating surface ocean biological productivity over the timescale of centuries to millennia. We calibrate the method using a global data set composed of 207 samples from the Atlantic, Pacific, and Indian Oceans from a water depth range between 2300 and 3600 m. The sample set was developed so that other, potentially significant, environmental variables would be uncorrelated to overlying surface ocean productivity. A regression of assemblages against productivity yielded an ? = 0.89 demonstrating a strong productivity signal in the faunal data. In addition, we examined assemblage response to annual variability in biological productivity (seasonality). Our data set included a range of seasonalities which we quantified into a seasonality index using the pigment color bands from the coastal zone color scanner (CZCS). The response of benthic foraminiferal assemblage composition to our seasonality index was tested with regression analysis. We obtained a statistically highly significant r 2 = 0.75. Further, discriminant function analysis revealed a clear separation among sample groups based on surface ocean productivity and our seasonality index. Finally, we tested the response of benthic foraminiferal assemblages to three different modes of seasonality. We observed a distinct separation of our samples into groups representing low seasonal variability, strong seasonality with a single main productivity event in the year, and strong seasonality with multiple productivity events in the year. Reconstructing surface ocean biological productivity with benthic foraminifera will aid in modeling marine biogeochemical cycles. Also, estimating mode and range of annual seasonality will provide insight to changing oceanic processes, allowing the examination of the mechanisms causing changes in the marine biotic system over time.

In order to study the fossil contents of the Ziarat-kola section for biostratigraphical purposes the 212 meters was sampled at Central Alborz. The sequence is mainly made up of monotonous grey-green to light grey marl. Based on Planktonic foraminifera age of Maastrichtian-Danian is determined to the section.Four zone were determined by the benthic foraminifera morphogroup for showing oxygen and productivy change. The approximate Low oxygen and high food supply has been indicates zone of one that increase infauna to epifauna morphotype percent is low(nearness 60% infouna , 40% epifauna). In zone two, with due attention to equal percent of Epifauna ratio to infauna , intermediate oxygen and food supply is anticipated .The decrasing epifauna foraminifera and increasing infauna demonstrates low oxygen and high food supply condition at zone of three. In zone four, increasing epifauna (approximate 90 percent) that are indicated high oxygen condition and low food supply. Analysis of planktonic foraminifera assemblage at this section with Cretaceous biostratigraphical provinces is indicating a close similarity with Tethyan provinces.
