Interactive comment on “Variation in stable carbon and oxygen isotopes of individual benthic foraminifera: tracers for quantifying the vital effect” by T. Ishimura et al

چکیده
The paper entitled “Variation in stable carbon and oxygen isotopes of individual benthic foraminifera: tracers for quantifying the vital effect” by Ishimura San et al. deals with the applicability of inter-individual delta13C and delta18O distributions (Standard Deviation within species) to reconstruct the bottom water isotopic signatures. This work is based on live and dead (assumed as modern) foraminifera that were sampled at 4 deepsea sites, off Japan. Different species and genera, with different individual weights (i.e. size), were analyzed individually and their isotope signatures were compared with bottom water delta13CDIC and delta18Oe.c.. Within a species, lower delta13C and

متن کاملInteractive comment on “A reappraisal of the vital effect in benthic foraminifera on Mg/Ca ratios: species specific uncertainty relationships” by J. C. Wit et al
This paper focuses on inter-individual variability and temperature sensitivity of Mg incorporation in calcite shells of the benthic foraminifer Bulimina marginata. The manuscript is well-written; in particular, the Discussion section is well-thought-through. The topics attract many readers interested in biocalcification and paleo-temperature reconstructions. However, I consider this paper needs...

P4948 L7: I do not think Mg/Ca values correlate “well” with temperature because of R2=0.28. L18-21: The sentences give a vague impression. Better to rewrite more specifically.
متن کاملAnomalous shifts in tropical Pacific planktonic and benthic foraminiferal test size during the Paleocene–Eocene thermal maximum
Paleocene–Eocene warming and changes in oceanic hydrography should have significantly impacted the ecology of marine microorganisms, both at the surface and on the seafloor. We analyzed several key characteristics of foraminifera from two Shatsky Rise (ODP Leg 198) cores spanning the P/E boundary including the maximum test diameters of the largest calcareous trochospiral benthic foraminifera an...
متن کاملPartial collapse of the marine carbon pump after the Cretaceous-Paleogene boundary
The impact of an asteroid at the end of the Cretaceous caused mass extinctions in the oceans. A rapid collapse in surface to deepocean carbon isotope gradients suggests that transfer of organic matter to the deep sea via the biological pump was severely perturbed. However, this view has been challenged by the survival of deep-sea benthic organisms dependent on surface-derived food and uncertain...
