AbstractTwo practical problems in the use of time-lapse photography for the measurement of speed were encountered during the recent surge of West Fork Glacier in the central Alaska Range, Alaska, U.S.A. The first is severe rotational camera instability; we show how natural, unsurveyed features on the valley wall can be used to make the necessary corrections. The second problem is the computation of absolute speed when many different, unsurveyed glacier-surface features are used as targets. We give a method for connecting the data obtained from different targets, and for determining the scale using limited information obtained by surveying. Severe systematic errors can occur unless the angle between the axis of the lens and the direction of horizontal motion is determined.

The endogenous activity rhythm of the estuarine amphipod Corophium volutator has been studied by direct observation and with the use of time lapse photography. The rhythm persists under constant conditions having a free running period of between 12 and 13 h, and with activity maxima occurring during the early ebb. Freshly collected animals show a rhythm which is modulated on a semi-lunar basis, the activity maxima being attenuated during the neap tide periods, and the rhythm has also been found to vary in definition throughout the year. The activity pattern is most clearly denned in early summer and autumn, the population becoming arrhythmic during the winter months. The rhythm is relatively unaffected by the ambient light intensity and temperature of the recording conditions, and is evident in all post-natal stages of development. The possibility of mutual entrainment is discussed.

Time Lapse Photography

Time-lapse photography—the extremely accelerated recording and projection of an event taking place over an extended duration of time—is almost as old as the movies themselves. (The first known use of time-lapse dates from 1898.) In the early decades of the twentieth century, cineastes, not to mention scientists, artists, and poets, waxed eloquently on the promise of time-lapse photography as a means for revealing “things we cannot see,” and expanding human perception. This essay examines time-lapses tremendous initial imaginative appeal for such figures as Ernst Mach, Germaine Dulac, Jean Epstein, Rudolf Arnheim, Laszlo Moholy-Nagy, and Collette, and speculates about the possible reasons for its diminution over the course of the century.

Time Lapse Photography

The use of time-lapse photography in combination with sonar as a means of observing the sockeye salmon (Oncorhynchus nerka) smolt migration in a large lake is discussed. A description of the gear used is given with some examples of the type of information that can be derived from this technique.The scanning rate of the sonar equipment used, combined with time-lapse photography, resulted in a compression of time to [Formula: see text] when scanning at a range of 400 ft and to [Formula: see text] at a range of 800 ft. A 24-hr period may thus be viewed on film in respectively S and [Formula: see text] when projected at a speed of 24 frames/sec. This speeded-up process facilitates separation of moving targets from stationary ones, even in the clutter of surface and/or ground echoes.Although subject to all the usual vagaries of target identification which accompany use of all echo-sounding gear, analysis of the movies with a time-motion projector appears to give meaningful information on such parameters as the speed and direction of migration or movement, and the distribution of migratory activity throughout a 24-hr period.
