A number of other functions have been proposed that relate piston velocity to wind speed. These are shown along with the Liss and Merlivat [59] relationship in Fig. 5. On the basis of TTO data from measurements in the Equatorial Atlantic using the radon deficiency method, Smethie et al. [62] proposed a linear relationship between wind speed and gas exchange. Wanninkhof [26] proposed a quadratic function and noted the effect of using an average wind speed when the dependence of exchange on wind speed is nonlinear. The relationship is for steady winds or short-term winds and was determined from the data for bomb 002 and the wind speed distribution around the global mean wind speed. The model predictions of Deacon [28], also shown in Fig. 5, are appropriate only to low wind speeds. 

In a rock from the mid-Atlantic rise, the atomic ratio Pb/ U (corrected for Pb not generated by in the rock) is 1.128. (a) For every 1 mole of now present in the rock, how many moles were present when the rock was formed (b) Calculate the age of the rock, (c) See Fig. 25.5 (page 538). Does the leakage of radon from uranium minerals introduce a positive or a negative error in the age of the mineral ...
