“…Chamber addition continued in steps until all chambers were added. G. ruber typically adds between 15 and 17 chambers (Parker, 1962), so a terminal chamber count of 16 was used in all models (Table 2).…”

Size-dependent response of foraminiferal calcification to seawater carbonate chemistry

Abstract. The response of the marine carbon cycle to changes in atmospheric CO 2 concentrations will be determined, in part, by the relative response of calcifying and non-calcifying organisms to global change. Planktonic foraminifera are responsible for a quarter or more of global carbonate production, therefore understanding the sensitivity of calcification in these organisms to environmental change is critical. Despite this, there remains little consensus as to whether, or to what extent, chemical and physical factors affect foraminiferal calcification. To address this, we directly test the effect of multiple controls on calcification in culture experiments and core-top measurements of Globigerinoides ruber. We find that two factors, body size and the carbonate system, strongly influence calcification intensity in life, but that exposure to corrosive bottom waters can overprint this signal post mortem. Using a simple model for the addition of calcite through ontogeny, we show that variable body size between and within datasets could complicate studies that examine environmental controls on foraminiferal shell weight. In addition, we suggest that size could ultimately play a role in determining whether calcification will increase or decrease with acidification. Our models highlight that knowledge of the specific morphological and physiological mechanisms driving ontogenetic change in calcification in different species will be critical in predicting the response of foraminiferal calcification to future change in atmospheric pCO 2 .

“…Foraminifera were least abundant at sites 722 and 758 where one-half to all of the specimens were picked for analysis. Individual specimens were identified to species level, generally following the taxonomy of Parker (1962Parker ( , 1967 and Blow (1969) with modifications (Dowsett and Robinson, 2007), and glued to a 60-square micropaleontological slide. 709, 716, 722, 754, 757, 758, and 763 described in this study and mean mid-Piacenzian planktic foraminifer species distribution at those sites.…”

“…In total there are 16 343 modern specimens: 15 355 macroperforate and 988 microperforate (Table 2). Buckley mainly used the taxonomy of Parker (1962) and was able to identify 33 morphospecies in the collection, which are well spread throughout the phylogeny of planktonic foraminifera and cover all recognized ecogroups (Aze et al 2011).…”

The Henry Buckley Collection of Planktonic Foraminifera at the Natural History Museum in London (NHMUK) consists of 1665 single-taxon slides housing 23 897 individuals from 203 sites in all the major ocean basins, as well as a vast research library of Scanning Electron Microscope (SEM) photomicrographs. Buckley picked the material from the NHMUK Ocean-Bottom Deposit Collection and also from fresh tow samples. However, his collection remains largely unused as he was discouraged by his managers in the Mineralogy Department from working on or publicizing the collection. Nevertheless, Buckley published pioneering papers on isotopic interpretation of oceanographic and climatic change and was one of the first workers to investigate foraminiferal wall structure using the SEM technique. Details of the collection and images of each slide are available via the NHMUK Data Portal (http://dx.doi.org/10.5519/0035055). The Buckley Collection and its associated Ocean-Bottom Deposit Collection have great potential for taxon-specific studies as well as geochemical work, and both collections are available on request
