Science / Tides and Currents / Apparent Secular Trend: The non-periodic tendency of sea level to rise, fall, or remain stationary with time. Technically, it is frequently defined as the slope of a least-squares line of regression through a relatively long series of yearly mean sea-level values. The word 'apparent' is used since it is often not possible to know whether a trend is truly non-periodic or merely a segment of a very long oscillation (relative to the length of the series).
