Abstract

A record of foraminiferal shell weight across glacial-interglacial Termination I shows a response related to seawater carbonate ion concentration and allows reconstruction of a record of carbon dioxide in surface seawater that matches the atmospheric record. The results support suggestions that higher atmospheric carbon dioxide directly affects marine calcification, an effect that may be of global importance to past and future changes in atmospheric CO 2 . The process provides negative feedback to the influence of marine calcification on atmospheric carbon dioxide and is of practical importance to the application of paleoceanographic proxies.

  15. For weight analysis 20 to 24 individual shells were picked with care given to ensuring the highest degree of morphological consistency. The shells were weighed using a seven-place microbalance (precision = 0.1 μg) the mean weight being taken to represent that population. Size analysis of foraminiferal tests was performed on digital photomicrographs using OPTIMAS image analysis software. Two-dimensional analysis of individual sample populations allows measurement of mean major axis length ( L ) and cross-sectional area ( A ). These values may be used to normalize the mean weight of the sample to the average size for that sieve-size fraction. In this case normalized L = 436 μm and A = 0.113 mm 2 .

  20. [CO 3 2– ] values were calculated from TA TCO 2 T P S [PO 4 ] and [SiO 4 ] taken from the North Atlantic WOCE database (26) using the CO2SYS program (version 01.05) (27). Adjustment to preindustrial values was made by recalculation via CO2SYS using preindustrial P co 2 (= 0.8 × modern P co 2 ) values. Values of [CO 3 2– ] used in the calibration were calculated for a particular sample via the temperature (28) for June at 30-m water depth (assumed calcification season and depth of G. bulloides ) for the sample site.
  21. The CO 2 record used here is plotted on the time scale calculated by tuning Vostok δ 18 O to the June insolation curve at 65°N (29). Using this time scale allows for better correlation between ice-cores and marine records.
  22. Empirical values of K 0 1 2 in terms of T and S were taken from Millero (30). Carbonate alkalinity CA ([HCO 3 – ]+2[CO 3 2– ]) is considered equal to 96% of TA allowing for the contributions from borate and water (plus minor others) alkalinity. The value of 96% is taken from Zeebe and Wolf-Gladrow (31) as a typical seawater example (TA ≈ PA = 2300 μmol kg -1 DIC = 2000 μmol kg -1 T = 25°C S = 35).
