| [1] In this paper, we compile the current surface seawater C(37) alkenone unsaturation (U(37)(K')) measurements ( n = 629, - 1 to 30 degrees C temperature range) to derive a global, field-based calibration of U(37)(K') with alkenone production temperature. A single nonlinear "global'' surface water calibration of U(37)(K') accurately predicts alkenone production temperatures over the diversity of modern-day oceanic environments and alkenone-synthesizing populations (T = - 0.957 + 54.293(U(37)(K')) - 52.894(U(37)(K'))(2) + 28.321(U(37)(K'))(3), r(2) = 0.97, n = 567). The mean standard error of estimation is 1.2 degrees C with insignificant bias in estimated production temperature among the different ocean regions sampled. An exception to these trends is... |
