  abstract = {{P}revious studies have demonstrated the potential for the {L}i content of coral aragonite to record information about environmental conditions, but no detailed study of tropical corals exists. {H}ere we present the {L}i and {M}g to {C}a ratios at a bimonthly to monthly resolution over 25 years in two modern {P}orites corals, the genus most often used for paleoclimate reconstructions in the tropical {I}ndo-{P}acific. {A} strong relationship exists between coral {L}i/{C}a and locally measured {SST}, indicating that coral {L}i/{C}a can be used to reconstruct tropical {SST} variations. {H}owever, {L}i/{C}a ratios of the skeleton deposited during 1979-1980 do not track local {SST} well and are anomalously high in places. {T}he {M}g/{C}a ratios of this interval are also anomalously high, and we suggest {L}i/{C}a can be used to reconstruct tropical {SST} only when {M}g/{C}a data are used to carefully screen for relatively rare biological effects. {M}g/{L}i or {L}i/{M}g ratios provide little advantage over {L}i/{C}a ratios, except that the slope of the {L}i/{M}g temperature relationship is more similar between the two corals. {T}he {M}g/{L}i temperature relationship for the coral that experienced a large temperature range is similar to that found for cold water corals and aragonitic benthic foraminifera in previous studies. {T}he comparison with data from other biogenic aragonites suggests the relationship between {L}i/{M}g and water temperature can be described by a single exponential relationship. {D}espite this hint at an overarching control, it is clear that biological processes strongly influence coral {L}i/{C}a, and more calibration work is required before widely applying the proxy.},
