Table S6. Pearson correlation coefficients for comparisons between metric time series derived from the Scottish West Coast Groundfish Survey (SWCGS) undertaken in the first (Q1) and fourth (Q4) quarters of the year in the southwestern sector of the Scottish Continental Shelf sub-region. In columns headed 1y lag, a plus one-year lag was introduced to the Q4 survey time series. The row marked “No years” indicates the number of years overlap between the two series in the correlation analysis. Coefficients in bold are statistically significant (P<0.05) in a one-way test (only positive relationships considered significant).

Table S7. Pearson correlation coefficients for comparisons between metric time series derived from the International Bottom Trawl Surveys (IBTS) undertaken in the first (Q1) and third (Q3) quarters of the year in the northwestern sector of the Scottish Continental Shelf sub-region. In columns headed 1y lag, a plus one-year lag was introduced to the Q4 survey time series. The row marked “No years” indicates the number of years overlap between the two series in the correlation analysis. Coefficients in bold are statistically significant (P<0.05) in a one-way test (only positive relationships considered significant).

Figure S1. Trends in fifteen metrics quantifying different aspects of the composition, structure and functioning of the demersal fish assemblage in the Northern North Sea sub-region. Metrics are applied to data derived from ICES co-ordinated International Bottom Trawl Surveys carried out in the first (Q1) and third (Q3) quarters of the year. See Table 1 (in main body of report) for explanation of metrics (y axis labels).
