Increased CO

emissions into the atmosphere lead to increased concentration of dissolved CO

in the ocean. Chemical reactions
between the dissolved CO

and seawater transform the dissolved CO

into HCO

and produce H+ ions. These
ions increase the acidity of seawater and decrease pH. Increased acidity and decreased availability of calcium and magnesium
ions affect carbonate and aragonite production by marine calcifiers in the Pacific Ocean. Large benthic foraminifera, such as
Marginopora vertebralis Quoy and Gaimard, 1830, produce calcite with high magnesium (Mg) content and have an important
role in sand building on Pacific Islands. It is thus important to better understand the biomineralization processes in foraminifers
for predicting their calcification response to ocean acidification. To assess the response of benthic foraminifer to changing
carbondioxide levels,we cultured Marginopora vertebralis Quoy and Gaimard, 1830 at three different pH levels (pH 7.5,pH 7.8
and pH 8.1(ambient seawater).The fluorescent compound calcein ( 40 micromoles/litre) was added to the culturing tanks to
mark the calcite growth during the culturing period. The specimen grown in the laboratory were analysed using laser ablation-
inductively coupled plasma mass spectroscopy (LA-ICPMS) and electron probe micro analyser (EPMA) to measure elemental
compositions and (B/Ca, Mg/Ca and Sr/Ca) ratios. Results indicate that the shell weight decreased with decreasing pH level. The
elemental ratios also decreased with decreasing pH.
