Summary of top two cov values for each pair-wise cross-covariance analysis.

Initial variables are listed in columns and include shallow temperature (ShTemp), deep temperature (DpTemp), shallow salinity (ShSal), deep salinity (DpSal), stratification (Δσ), shallow Chl a fluorescence (ShChl), mid-column Chl a fluorescence (MidChl), total scattering (Sv), small crustaceans (SmCrust), medium crustatceans (MdCrust), large crustaceans (LgCrust), weak resonant scatterers (WkReson), strong resonant scatterers (StReson), unclassified scatterers (Unclass). Ice extent (% Ice) and thickness (cmIce) were also used. Comparison variables yielding the highest absolute cov values are listed under “Variable” in each year. Lags are indicated in days, Positive lag values indicate a lag of the comparison variable (column) relative to the initial variable (row); negative values indicate a lead of the comparison value (column) relative to the initial variable (row).Summary of top two cov values for each pair-wise cross-covariance analysis.
