| "We examined interannual change in several physical environmental indexes to isolate the main scales of variation previously reported—the high (~5–7 years), decadal-bidecadal (~20–30 years), and very low frequency (~50–75 years)—in the California Current system. We employed smoothing filters for the purpose of isolating the scales, using their spectral frequencies to analyze their adequacy. In the case of the decadal-bidecadal scale, we tested the coherence between the series against that of random number series. Later, we extracted the first principal component from all series at each scale of variation and compared this to published information, to the physical mechanisms, and to their effects on biological indexes associated with each. We suggest that all the examined frequencies of interannual variation are related to two opposing states of the system, one state associated with relaxed flow of the California Current; intensification of the Aleutian Low, the Alaska Current, and the California countercurrent; increased coastal sea-surface temperatura and sea level; frequent mesoscale eddies formation and persistence; and northward advection of southern fauna; the other state associated with the contrary." | |
