Vertical distribution of Euchaeta media female from day and night tows taken over (solid lines) and away from (dashed lines) the seamount Fieberling Guyot (32°25'N, 127°47'W).

Cumulative sums of nonseasonal anomalies from the long-term means of copepod abundance .
A negative slope indicates a period of below-average anomalies; a positive slope indicates a period of above-average anomalies. Abrupt changes in slope indicate step changes. Step changes are marked with arrows (downward -pointing for decreases).
The October 1966 cruise (prior to the increase in sampling depth), March 1976 cruise (prior to the 1976-77 climatic regime shift), and October 1988 cruise (prior to the hypothesized 1989 climatic regime shift) are marked with vertical lines. |
