Chapter Seven Paleoceanographical Proxies Based on Deep-Sea Benthic Foraminiferal Assemblage Characteristics
Publisher Summary This chapter focuses on the paleoceanographical proxies based on deep-sea benthic foraminiferal assemblage characteristics, and presents the following three proxy relationships that
Live benthic foraminiferal faunas from the Bay of Biscay: faunal density, composition, and microhabitats
The exported flux of organic matter appears to be the main parameter controlling the composition and the vertical distribution of benthic foraminiferal faunas below the sediment-water interface.
Stable oxygen and carbon isotopes of live benthic foraminifera from the Bay of Biscay: Microhabitat impact and seasonal variability
We determined the stable oxygen and carbon isotopic composition of live (Rose Bengal stained) benthic foraminifera (N150 Am size fraction) of seven taxa sampled along a downslope transect between 140
A dynamic concept for eastern Mediterranean circulation and oxygenation during sapropel formation
We propose that intermittent bottom water ventilation occurred throughout periods of sapropel deposition, and that the recently reported sapropel ‘interruptions’ represent centennial-scale episodes
Seasonal and interannual variability of benthic foraminiferal faunas at 550 m depth in the Bay of Biscay
Abstract Live benthic foraminiferal faunas were sampled 10 times between October 1997 and April 2000 at a 550 m depth open-slope station in the Bay of Biscay. Duplicate cores for 5 samplings allow
Timing of massive ‘Fleuve Manche’ discharges over the last 350 kyr: insights into the European ice-sheet oscillations and the European drainage network from MIS 10 to 2
Continuous high-resolution mass accumulation rates (MAR) and X-ray fluorescence (XRF) measurements from marine sediment records in the Bay of Biscay (NE Atlantic) have allowed the determination of
Circulation changes and nutrient concentrations in the late Quaternary Aegean Sea: A nonsteady state concept for sapropel formation
sapropel-forming conditions, we identify the start of ‘‘seasonal’’ stratification and highlight a lag in d 18 O response of the planktonic foraminifer N. pachyderma to termination T1b as identified
Spatial distribution of live benthic foraminifera in the Rhône prodelta: Faunal response to a continental–marine organic matter gradient
Benthic foraminifera were collected in the Rhone prodelta (Gulf of Lions, Mediterranean Sea), an enriched zone with high organic matter content. In June 2005, sediment cores were sampled at depths
Tracking rainfall in the northern Mediterranean borderlands during sapropel deposition
The role of mid-latitude precipitation in the hydrological forcing leading to the deposition of sapropels in the Mediterranean Sea remains unclear. The new GDEC-4-2 borehole, East Corsica margin
Live (stained) benthic foraminifera in the Whittard Canyon, Celtic margin (NE Atlantic)
Living (Rose Bengal stained) benthic foraminifera were investigated at 18 deep-sea stations sampled in the Whittard Canyon area (NE Atlantic). The stations were positioned along 4 bathymetric
