GLM and GLMM final model results.

The letter c denotes centered variables. Ice cover is given as a fraction of cover from 0 to 1, large crustacean represents a percent composition, and both 10 kHz and 40 kHz are given in dB re 1 µPa2/Hz. The random intercept for site in the GLMM has a standard error of 0.0001 and residual standard error of 0.871. The explanatory variable large crustacean does not meet significance selection criteria (p<0.01), however is included due to the significance of its interaction term with ice cover.
GLM and GLMM final model results.

字母c用于指代中心化变量（centered variables）。冰盖覆盖率以0到1之间的分数值表征；大型甲壳动物类群的组成占比以百分比计；10 kHz与40 kHz的量值均以参考1微帕平方每赫兹的分贝（dB re 1 µPa²/Hz）为单位。广义线性混合模型（Generalized Linear Mixed Model, GLMM）中样地的随机截距项标准误为0.0001，残差标准误为0.871。解释变量大型甲壳动物类群未达到显著性筛选标准（p<0.01），但由于其与冰盖覆盖率的交互项具有统计学显著性，故仍将其纳入模型。
