  abstract = {{T}he oxygen isotope composition (delta {O}-18) of diatoms is commonly used for paleoclimate reconstruction. {T}here is, however, no consensus regarding the equilibrium isotopic fractionation factor between diatom silica and the water in which it is precipitated. {W}e re-examined the temperature-dependent relationship between delta {O}-18(diatoms) and delta {O}-18(lake water) from {L}ake {A}nnecy ({F}rance). {A} temperature coefficient of -0.16a{E}uro degrees/{A} degrees {C} ({R} (2) = 0.51) was determined, supporting findings from previous calibration studies. {H}owever, regression lines obtained from different calibration studies, though displaying similar slopes, were shifted. {I}n this manuscript, we propose that several factors, including selected variables (temperature, delta {O}-18(lake water)), analytical techniques, the impact of diagenetic processes and biological effects, may influence the silica-water fractionation factor for diatom silica. {T}he similar magnitude of the diatom-temperature coefficients determined across studies is promising, supporting its use as a valuable tool for interpreting variations in delta {O}-18 values from fossil lacustrine diatoms in temperate lakes. {W}ith respect to paleoclimatic applications, the temperature-dependent relationship yielded uncertainties of +/- 3{A} degrees {C} on reconstructed temperatures and +/- 0.5a{E}uro degrees on delta {O}-18(lake water).},
