Correlations between fish abundance and other proxy records for age-based pairs.

The number of significant (Sig., p < 0.05) correlations are listed for each available proxy record vs. all fish abundance records at the same site. Of these, the number of positive (i.e. r > 0) regression coefficients are indicated in the ‘Sig.+ve’ column, and the percentage of significant correlations among the total pairs tested is given in the ‘Sig.%’ column. The ‘dt’ columns show the corresponding values for the linearly-detrended records.
