Abstract Fossil remnants of benthic foraminifera consist of carbonate tests and their organic linings. The macromolecular and stable isotopic composition of these benthic foraminiferal organic linings was characterized to evaluate their potential use as paleoclimate proxies. Using Curie point pyrolysis–GC–MS (Py–GC–MS) we show that benthic foraminiferal organic linings consist of protein and polysaccharides, bound together in a complex macromolecular structure. Both chitin derivatives and… Expand
Foraminiferal organic linings: Functional and phylogenetic challenges
Abstract Foraminifera are commonly applied as essential tools for relative time control and reconstructions of paleo/environmental conditions. These single-celled organisms leave in the sedimentaryExpand

Element banding and organic linings within chamber walls of two benthic foraminifera
Evaluated and synthesized models of underlying mechanisms responsible for trace and minor element partitioning during calcification in foraminifera show that Mg, Na, Sr and K are co-located within shells, and occur in bands that coincide with organic linings but extend further into the calcite lamella.

Correlation between the carbon isotopic composition of planktonic foraminifera-bound organic matter and surface water pCO2 across the equatorial Pacific
Abstract For times prior to those represented by the air trapped in Antarctic ice core records, the concentration of CO2 in the atmosphere must be reconstructed using geochemical proxies. The δ13C ofExpand
Sulfur in foraminiferal calcite as a potential proxy for seawater carbonate ion concentration
Abstract Sulfur (S) incorporation in foraminiferal shells is hypothesized to change with carbonate ion concentration [ CO 3 2 − ], due to substitution of sulfate for carbonate ions in the calciteExpand
Double Trouble : Foraminiferal calcification in a changing ocean
Within the project ‘Double Trouble: Foraminiferal Calcification in a Changing Ocean’, I tried to illuminate mechanisms determining element incorporation in foraminifera with different calcificationExpand
Chemical Heterogeneity of Mg, Mn, Na, S, and Sr in Benthic Foraminiferal Calcite
The chemical composition of fossil foraminiferal shells (tests) is widely used as tracers for past ocean chemistry. It is, therefore, important to understand how different (trace) elements areExpand
Microbial Alteration of Carbonate Archives
Marine biogenic carbonates are comprehensive archives of paleoenvironmental conditions. The main environmental variables that can be deduced from carbonate elemental- and isotopic composition areExpand
Manganese incorporation in living (stained) benthic foraminiferal shells: a bathymetric and in-sediment study in the Gulf of Lions (NW Mediterranean)
Abstract. Manganese geochemistry in deep-sea sediments is known to vary greatly over the first few centimeters, which overlaps the in-sediment depth habitats of several benthic foraminiferal species.Expand


Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes
Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic organisms, 18O/16OExpand
Ecological significance of benthic foraminifera: 13C labelling experiments
The ability of foraminifera in taking up freshly deposited algal carbon in intertidal estuarine sediments and the significant contribution of foraminaifera to meiobenthic abundance and biomass suggest that foraminifiera play an important role in the carbon cycle in these sediments. Expand
