TLDR
The benthic foraminiferal assemblages of two cores from the late-Holocene, organic-carbon-rich and carbonate-poor, deep-sea sediments of the eastern depression of the Sea of Marmara have been studied.About:

Benthic foraminifera in oxygen-poor habitats
TL;DR: Present data from modern environments do not support the hypothesis that most dysoxic-su☐ic benthic foraminifers, regardless of their phylogeny, are characterized by a particular test morphology.

Spatial distribution of live benthic foraminifera in the Rhône prodelta: Faunal response to a continental–marine organic matter gradient
Meryem Mojtahid,Frans Jorissen,Bruno Lansard,Christophe Fontanier,Bruno Bombled,Christophe Rabouille +5 more
TL;DR: In this article, sediment cores were sampled at depths ranging from 20 to 100m and four distinct foraminiferal assemblages were determined in the study area, reflecting the geographical distribution of the impact of river supply.

Late Glacial to Holocene benthic foraminifera in the Marmara Sea: implications for Black Sea–Mediterranean Sea connections following the last deglaciation
Michael A. Kaminski,Ali E. Aksu,Matthew Box,Richard N. Hiscott,Sorin Filipescu,Sorin Filipescu,Muna Al-Salameen +6 more
TL;DR: Benthic foraminifera were studied from four gravity cores that penetrated Holocene marine sediments in the Marmara Sea, and morphogroup and assemblage analyses reveal that the Holocene sea-level rise did not result in a catastrophic flooding event as proposed by W.B.F. Ryan and others, whereby well-oxygenated, saline Mediterranean waters rapidly inundated a low-lying low salinity ‘Black Sea Lake’ at V7.15 ka (popularly known as the ‘Noah’s Flood Hypot

Benthic foraminiferal response to changes in bottom-water oxygenation and organic carbon flux in the eastern Mediterranean during LGM to Recent times

TL;DR: In this paper, a high-resolution study of benthic foraminiferal abundances in 4 cores from the central Aegean and NE Levantine Seas, spanning the interval from 30-ka BP to the present, is presented.

Climatic forcing of eastern Mediterranean deep-water formation and benthic ecosystems during the past 22 000 years
Gerhard Schmiedl,Tanja Kuhnt,Werner Ehrmann,Kay-Christian Emeis,Yvonne Hamann,Ulrich Kotthoff,Peter Dulski,Joerg Pross +7 more
TL;DR: In the early Holocene, oxygen levels decreased exponentially with increasing water depth, suggesting a basin-wide shallowing of vertical convection superimposed by local signals as discussed by the authors, and the recovery of benthic ecosystems during the terminal phase of S1 formation is controlled by subsequently deeper convection and reventilation over a period of approximately 1500 years.

Anoxic Environments and Oil Source Bed Genesis
TL;DR: The anoxic aquatic environment is a mass of water so depleted in oxygen that virtually all aerobic biologic activity has ceased as discussed by the authors, where the demand for oxygen in the water column exceeds the supply.

Microhabitats of benthic foraminifera within deep-sea sediments
TL;DR: In this article, an analysis of living (stained) benthic foraminifera within the upper 15 cm of deep-sea sediments, which reveals species-specific microhabitat preferences, with distinct morphological features found with epifaunal and infaunal species.

Evolutionary and ecologic significance of oxygen‐deficient marine basins
Donald C. Rhoads,John W. Morse +1 more
TL;DR: The basin model has been used to reconstruct a Lower Cambrian oxygen level of 0.1 P.L.A. (present atmospheric level). This value is tenfold that proposed in the Berkner-Marshall hypothesis as discussed by the authors.

The Black Sea--Geology, Chemistry, and Biology

TL;DR: The study of marginal seas has been a long-term interdisciplinary study area, and the Black Sea, being the largest anoxic basin in the world, is intriguing both chemically and geologically.
