在第103页“计算”副标题下，“经验换算系数是按Ducklow和Hill(1985)建议的修正导数法计算的”应改为：经验换算系数是用综合法计算的。我们在早期版本的手稿中使用了衍生方法，但最终决定使用综合方法。尽管提供了正确的公式和数据，但我们忽略了如上所示对文本进行适当的更改。关于综合方法的主要批评是，在计算中只使用了生物体积曲线的两个点(第一个B0和最后一个Bt)。导数法通常受到青睐，因为它考虑了整条曲线。然而，如果参数是从非线性回归曲线确定的(使用Systat等统计软件而不是在Excel中)，则可以使用综合法使用所有点。我们认为这是一种比导数法更精确的方法，导数法通过投影到对数数据的y轴来确定初始参数。
On page 103, immediately under the subheading “Calculations,” the phrase "The empirical conversion factor was calculated by the modified derivative method as suggested by Ducklow and Hill (1985)” should read: The empirical conversion factor was calculated by the integrative method. We had used the derivative method in an earlier version of the manuscript but, ultimately, decided to use the integrative approach. Although the correct equation and data are presented, we neglected to make the appropriate change to the text as shown above. The main criticism regarding the integrative approach is that only two points of the biovolume curve (the first, B0, and the last, Bt) are used in the calculation. The derivative method is often favored because it considers the entire curve. However, it is possible to use all points with the integrative method if parameters are determined from nonlinear regression curves (done with statistics software such as Systat, not in Excel). We believe this is a more precise approach than the derivative method, which determines the initial parameters by projection onto the y axis of the logarithmic data.
