摘要: We present core top Mg/Ca, Sr/Ca and delta O-18 measurements for Cibicidoides wuellerstorfi Hoeglundina elegans from the Timor Sea Makassar Strait, which span a bottom water temperature (BWT) range 2 to 18 degrees C In both species Mg/Ca ratios are positively significantly correlated with BWT, while anti-correlated BWT Comparison of calcification temperatures derived yield comparable results closely match LW-measured temperatures. integrate our previously published data sets Atlantic, Indian Pacific Oceans provide calibration equations over 12 H. 0 10 C. wuellerstorfi. found geographical differences in relation benthic BWT: shows sensitivity 19% increase per Atlantic Ocean 15% Oceans. 16% 14% variability appears be mainly driven by carbonate ion saturation, whereas is linked compiled (C) 2015 Elsevier B.V.
