Therefore, we omit proloculus from our model and construct the arrangement from the second chamber. Seasonal temperatures in the euphotic zone. Planktic foraminifera are single-celled marine eukaryotes characterized by having calcareous shells. 35 ential palaeo-carbonate chemistry on Mg=Ca-derived reconstructions is rarely noted for planktic foraminifera, although a carbonate ion correction is routinely applied to some benthic foraminifera species (Sosdian and Rosenthal, 2009; Yu and Broecker, 2010). Spero HJ (1987) Symbiosis in the planktonic foraminifer, Spero HJ (1988) Ultrastructural examination of chamber morphogenesis and biomineralization in the planktonic foraminifer. A multitude of ecological conditions have been linked to size changes in planktic foraminifera, including pCO 2, SST, stratification, salinity, and nutrient levels (Schmidt, Thierstein, & Bollmann, 2004). The diversity of planktic foraminifera in polar oceans is lower than in mid- and low latitude settings, ... For example, first order differences in relative foraminifera abundances are seen in stratigraphically coeval sections of LOMROG12-7PC and AO16-5PC, particularly between the D B and the peach colored clay layer (PL) . It is small when the foraminifera has formed by sexual reproduction, but large when reproduction has been asexual.

Their biology, diversity, and shell chemistry are sensitive to changes in the oceanic environment, and therefore their carbonate shells are useful climatic tracers of temperature, water mass, and other chemical indicators of global change. For example, the distribution area of transitional and subpolar planktic foraminifera in the northern North Atlantic and Arctic oceans shifted further south during the last glacial maximum (LGM) (Kucera et al., 2005; Kucera, 2007) (Fig. Species abundance varies according to seasons, water masses, and water depths.

Ontogenetic stable isotope trends in some Late Cretaceous planktonic foraminifera. The small benthic foraminifera, which have simple internal structures, and the larger benthic foraminifera, which have complicated internal structures and occur abundantly in the shelf regions of most tropical and subtropical shallow marine, carbonate-rich environments (Boudagher-Fadel and Price, 2013). Not logged in Planktic foraminifera are normally observed to reproduce sexually in culture (6, 7, 13).

Little is known about Recent planktic foraminifera of Nigerian Continental Shelf. Planktic foraminifera have been studied for their stable isotopic signals since the pioneering work of Urey [1947, 1948] and Emiliani [1954, 1955] and have since evolved into the primary carriers of paleoclimate data in marine environments.

It is believed that they had evolved from one and/or some benthic foraminiferal lineages by the results of morphological analysis (e.g. Planktic foraminifers are absent in shallow marginal seas, for example, the North Sea. Benthic foraminifera have been used for palaeobathymetry since the 1930's and modern studies utilise a variety of techniques to reconstruct palaeodepths.
