We also found that large-scale climate indicators are good proxies demonstrate that the ocean climate, the timing of the bloom and the abundance of a key for the timing of the bloom and the abundance of Calanus finmarchicus, a key zooplankton species for the ecosystem. [...] The scorecard at the bottom of the figure shows the colour-coded numerical values of the NLCI. [...] Time series of the standardized anomalies of the initiation of the spring bands in panels a and b) represent the climatological (1998-2020) bloom in 3LNO from Modis and SeaWiFS sensors (orange curve) and the timing of 3. [...] capelin spawning after 1991 (Murphy et al., 2021) may have exacerbated the mis-match between this key species for the ecosystem and food availability, The NLCI and the timing of the bloom are and thus promoted the continued low productivity of the stock and of the NL good predictor of the biomass of Calanus ecosystem as a whole since the early 1990s. [...] The fluctuations of the NL climate, and thus the timing of the bloom and the abundance of this key zooplankton species, vary on decadal time scales.
