    Paleobathymetry—the determination of ancient water depth (paleodepth)—is the paleoenvironmental interpretation most widely used in petroleum exploration because of its value in determining the depositional history of a basin. Benthic foraminifera are usually used for this blogorazzia.com: Web page. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. Cd/Ca, δ13C and Mg/Ca of six species of benthic foraminifera with different microhabitat were analysed from throughout the sediment mixed layer at three well-characterised sites in the Northeastern Atlantic: Cibicidoides wuellerstorfi, Uvigerina peregrina, Cibicides bradyi, Melonis barleeanum, Bulimina.

[Lisa E Osterman; Geological Survey (U.S.)]. Jul 23,  · The surface benthic foraminiferal data provide the modern baseline conditions of the bay and can be used as a reference for changing paleoenvironmental parameters recorded in the box cores.

The 14 sampling locations were chosen in the bay to cover the wide diversity of fluvial and marine-influenced environments on both sides of the shipping channel (fig. 1, table 1 [KB Excel file]). Census data on benthic foraminifers (> μm) in surface sediment samples from 49 box cores are used to define four depth-controlled biofacies, which will aid in the paleoceanographic.

Five grab samples from the southwestern part of the Indian ocean were collected by ORV Sagar Kanya during the third expedition to the southern Indian ocean in June The sediment samples have been analyzed and recorded 36 benthic foraminiferal species belonging to 21 genera and 3 suborders.

All the species were taxonomically identified, SEM photographed and illustrated. Overview of proxy methods based on benthic foraminiferal assemblage data Proxies of bottom water oxygenation Paleoproductivity proxies calibrated on the basis of a large dataset of recent or core-top samples.

Eight box-core samples were collected along the inner, middle, and outer parts of the continental shelf. Each box-core sample was divided into 10 subsamples, of 1- to 5-cm intervals, in order to investigate the foraminiferal microhabitat preferences.
