“…Laboratory measurements on the symbiont-barren planktonic foraminifer Globigerina bulloides show a decrease of δ 13 C foram by 0.11‰ per temperature increase of 1°C (Bemis et al, 2000), which is twice as large and opposite in sign compared to our results. Bemis et al (2000) hypothesise though that increasing temperatures induce higher respiration rates, which, in turn, introduce more depleted δ 13 C CO 2 near the shell. After conversion from CO 2 to HCO 3 − and CO 3 2− , this carbon is subsequently taken up during calcification, thus lowering δ 13 C foram .…”

The δ 13 C value measured on benthic foraminiferal tests is widely used by palaeoceanographers to reconstruct the distribution of past water masses. The biogeochemical processes involved in forming the benthic foraminiferal δ 13 C signal (δ 13 C foram ), however, are not fully understood and a sound mechanistic description is still lacking. We use a reaction-diffusion model for calcification developed by Wolf-Gladrow et al. (1999) and Zeebe et al. (1999) in order to quantify the effects of different physical, chemical, and biological processes on δ 13 C foram of an idealised benthic foraminiferal shell. Changes in the δ 13 C value of dissolved inorganic carbon (δ 13 C DIC ) cause equal changes in δ 13 C foram in the model. The results further indicate that temperature, respiration rate, and pH have a significant impact on δ 13 C foram . In contrast, salinity, pressure, the δ 13 C value of particulate organic carbon (δ 13 C POC ), total alkalinity, and calcification rate show only a limited influence. In sensitivity experiments we assess how combining these effects can influence δ 13 C foram . We can potentially explain 33 to 47% of the interglacial-to-glacial decrease in δ 13 C foram by changes in temperature and pH, without invoking changes in δ 13 C DIC . Furthermore, about a quarter of the −0.4‰ change in δ 13 C foram observed in phytodetritus layers can be accounted for by an increase in respiration rate and a reduction in pH.

“…The observed Q 10 for respiration, 3.18, and the T A of 10,293uK are slightly higher than for tintinids (Verity 1985), microflagellates (Caron et al 1986), copepods (Vidal 1980), appendicularians (Lombard et al 2005), or euphausiids (Ross 1982); the Q 10 for these typically ranges between 1.5 and 2.8 in this temperature range. Our direct Q 10 estimates are also higher than previous ones calculated for foraminifera from indirect methods (based on the d 13 C of the shells), which give a Q 10 for respiration of between 2 and 2.75 (Ortiz et al 1996) and a Q 10 of ,1.6 for photosynthesis (Bemis et al 2000). Growth observations on foraminifera also give estimates of Q 10 of about 1.75 for O. universa (Caron et al 1987), and these estimates range from 2 to 9 for G. ruber, G. sacculifer, and O. universa (Bijma et al 1990).…”

Respiration and photosynthesis of the planktonic foraminifera Globigerinoides ruber, Orbulina universa, and Globigerinella siphonifera and their symbiotic algae were calculated from measured dissolved oxygen gradients using microelectrodes, using different temperatures in dark and light (250 mmol photon m 22 s 21 ) conditions. At one temperature (24uC) the respiration rate increased as a power function of the foraminiferan organic carbon mass with a 0.57 6 0.18 exponent. The effect of temperature on respiration was quantified in two ways: by normalizing the rates to the organic carbon mass and by normalizing the observed rates to a constant temperature (24uC). This latter normalization was also used for photosynthesis. The respiration rates increase as a function of temperature for all species and can be described either with a Q 10 5 3.18 (60.27) or with an Arrhenius temperature of T A 5 10,293uK (6768uK). Similar calculations for net photosynthesis yielded a Q 10 5 2.68 (60.36) and a T A 5 8766uK (61203uK), and calculations for gross photosynthesis yielded a Q 10 5 2.76 (60.29) and a T A 5 9026uK (6926uK). For the species studied, the photosynthesis : respiration ratio varied from moderate for G. siphonifera (0.58) to very high (13) for O. universa. The high ratios indicate that photosynthesis is much higher than the carbon requirements for both foraminifera and symbiont growth. This excess carbon might be the source of organic exudates.

“…The high δ 13 C DIC values found close to the sea surface are assumed to be caused by high primary production, resulting in enrichment in 13 C (Fogel and Cifuentes, 1993): as 12 C is taken for photosynthesis, the water becomes enriched in 13 C. However, if no other processes would affect the incorporation of carbon into the calcite shells, the tests should also show the enrichment in 13 C. One possible explanation for the deviation in the upper ∼ 75 m could be the effect of high (near-surface) temperatures on the carbon isotope incorporation of the tests. Laboratory (Bemis et al, 2000) and field experiments (Jonkers et al, 2013) have shown that foraminiferal δ 13 C linearly decreases with increasing temperatures. However, in our data set the offsets measured between δ 13 C DIC and δ 13 C foraminifera have no correlation with in situ water temperatures.…”

Abstract. The upper 500 m of the water column and the sediment surface along an E-W transect in the Fram Strait were sampled for recent planktic foraminifera. The δ 18 O and δ 13 C values of the tests are compared to the stable isotope composition of the water samples taken from the same depths, and related to the characteristics of the water column. The polar species Neogloboquadrina pachyderma clearly dominates the species assemblage in the Fram Strait in the early summer, while the subpolar Turborotalita quinqueloba accounts only for 5-23 %. In this area the average depth of calcification of N. pachyderma lies between 70-150 m water depth, T. quinqueloba shows a similar range with 50-120 m water depth. The δ 18 O values of N. pachyderma show an average vital effect of about −1.5 ‰ compared to calculated equilibrium calcite values. Except for the upper ∼ 75 m, the vertical profiles of δ 13 C of the net-sampled shells are nearly parallel to the values measured in the water column with an average offset of −1.6 ‰ and −3.6 ‰ for N. pachyderma and T. quinqueloba, respectively. The discrepancy found in the upper ∼ 75 m might indicate an influence of the "carbonate ion effect" on the carbon isotope incorporation in the tests. Oxygen and carbon isotopes from the sediment surface yield higher values than those from the water column for both species. This may be because specimens from the water column reflect a modern snapshot only, while tests from surface sediments record environmental parameters from the past ∼ 1000 years.
