The planktonic young drift freely in the ocean's pelagic zone. These clouds drift over the land and produce rain. During the winter, ice floes may drift south or north, depending upon the tides. Fertilized eggs drift with ocean currents and develop into larvae ("fry"). Sediment is transported along the coast in the direction of the prevailing current (longshore drift). Juveniles drift or swim freely, while adults are stationary. Does it not drift away from the bigger picture? This property confers resistance to melting on the ice of glaciers and drift ice. So does drift in the baseline signal over time. Often removal of linear drift can be sufficient. "steering" by the background environmental wind and "beta drift". For most species, the eggs drift on the surface. Its frequency increased as a consequence of high genetic drift within this population. The GPS calculated positions would quickly drift into error, accumulating to . An attribute will drift over time from Exciting to performance and then to essential.
