Abstract:

The aim of the study is to identify and record the taxonomic notes on species of Genus <em>Globigerinoides</em> from the study area located in Kafe field of the offshore western Niger Delta area of Nigeria. 550 ditch cuttings samples were retrieved at 18.29 metres intervals from the five wells studied (Kafe-1, Kafe-2, Kafe-4, Kafe-5 and Kafe-6). The standard micropaleontological preparation technique for foraminiferal samples was employed. The foraminiferal contents were identified under binocular microscope and recorded. The species of the Genus <em>Globigerinoides </em>identified are <em>Glo

A rich planktonic foraminiferal assemblage including two new species, Globorotalia sinuososuturalis n. sp. and Paragloborotalia lefkaraensis n. sp., have been recorded in the uppermost part of the sedimentary cover of Troodos Massif, exposed in Northern Cyprus. The continuity of chalk and marl deposits throughout the Aquitanian-Langhian time interval, with an abundant and well diversified assemblage, has provided to establish a detailed biostratigraphic framework which can be generally comparable with the recent standard and regional zonations.

The stable isotope composition of planktonic foraminifera correlates with evidence for pulses of terrigenous sediment in a sediment core from the upper continental slope off northeastern Brazil. Stable oxygen isotope records of the planktonic foraminiferal species Globigerinoides sacculiferand Globigerinoides ruber(pink) reveal sub-Milankovitch changes in sea-surface hydrography during the last 85,000 yr. Warming of the surface water coincided with terrigenous sedimentation pulses that are inferred from high XRF intensities of Ti and Fe, and which suggest humid conditions in northeast Brazil.

Abstract:

Abstract. The detailed test morphology of the type suite of specimens for the planktonic foraminifer Globigerinoides sacculifer (Brady) is illustrated for the first time since the species was identified in 1877. Fossil representatives of this species are a key index for oceanographic reconstruction of the Neogene and Quaternary tropics. The types of G. sacculifer, sourced from a loose ‘chalk’ block on a beach in New Ireland, Papua New Guinea, all bear a sac-like terminal chamber and are heavily calcified. They have undergone gametogenesis. Scanning electron microscopy identifies calcite fabric

Abstract:

Abstract. Synchronised reproduction offers clear benefits to planktonic foraminifera – an important group of marine calcifiers – as it increases the chances of successful gamete fusion. Such synchrony requires tuning to an internal or external clock. Evidence exists for lunar reproductive cycles in some species, but its recognition in shell flux time series has proven difficult, raising questions about reproductive strategies. Using spectral analysis of a 4-year time series (mostly at weekly resolution) from the northern Gulf of Mexico, we show that the shell flux of Globorotalia menardii, Glo

Abstract:

A foraminiferal biostratigraphy and paleoenvironmental studies were carried out on fifty (50) ditch-cut samples retrieved from the MASA-01 well, western offshore region, Niger Delta, Nigeria. The studied intervals ranged from 6810 feet (2076 m) to 8310 feet (2533 m) and were analyzed at intervals of 30 feet (9 m). The samples were subjected to foraminiferal and lithostratigraphy analyses to determine the biozonation and paleoenvironment of deposition. Standard foraminiferal preparation techniques completed with strata-bug software analysis were employed. Lithological studies indicate that the

Abstract:

Abstract Habitat patterns of subtropical and tropical planktic foraminifers in the Caribbean Sea were obtained from plankton samples collected in spring 2009 and 2013. The spatial distribution in surface waters (3.5 m water depth) and depth habitat patterns (surface to 400 m) of 33 species were compared with prevailing water-mass conditions (temperature, salinity, and chlorophyll-a concentration) and planktic foraminiferal test assemblages in surface sediments. Distribution patterns indicate a significant relationship with seawater temperature and trophic conditions. A reduction in standing st

Abstract:

Abstract Three anomalous zones of (i) Low planktonic foraminifera; (ii) High agglutinated foraminifera and (iii) Low-Globorotalia (Menardella) menardii and no-Bathysiphon filiormis are identified in the Exclusive Economic Zone off Godavari delta to Puri. The deviation from Wright-van Marle model of zone (i) can most probably be due to the non-production of Neogloboquadrina dutertrei and Globigerinoides ruber in the top water layers owing to a higher salinity zone probably created by the current patterns. The counter currents of low salinity are probably responsible for the Bathysiphon filiform

Abstract:

Abstract. Shell fluxes of planktonic Foraminifera species vary intra-annually in a pattern that appears to follow the seasonal cycle. However, the variation in the timing and prominence of seasonal flux maxima in space and among species remains poorly constrained. Thus, although changing seasonality may result in a flux-weighted temperature offset of more than 5° C within a species, this effect is often ignored in the interpretation of Foraminifera-based paleoceanographic records. To address this issue we present an analysis of the intra-annual pattern of shell flux variability in 37 globally

Abstract The foraminiferal contents of the lower–middle Miocene succession exposed in three sections in north Nur Abad on the northwestern side of the High Zagros Thrust Belt were studied. Assemblages of larger foraminifera from these sections can be referred to Zone SBZ 25 (and the Miogypsina globulus and Miogypsina intermedia subzones), which correlates with the Burdigalian Stage. For the first time, planktonic foraminifera documented from the Nur Abad area document Lang-hian deposits in the High Zagros, the upper 20 metres of the upper Sayl Cheshmeh section being characterised by the occurr
