We have no objective basis for identifying any of the experimental studies of sedimentation velocity as authoritative; none of the sampling apparatus were calibrated using standards (e.
The overall good fit between measured and predicted estimates of sedimentation velocity [ILLUSTRATION FOR FIGURE 5 OMITTED] provides a basis for some confidence in the measured values of Eisenhut (1961) and especially Durham (1946).
CONSEQUENCES OF MEASUREMENT UNCERTAINTY IN SEDIMENTATION VELOCITY
Estimates of sedimentation velocity for Quercus varied twofold, while those for Abies varied by a factor of 1.
2) for several important taxa (Picea, Pinus, Quercus, Betula, Alnus) owing to measurement uncertainties in sedimentation velocity [ILLUSTRATION FOR FIGURE 6 OMITTED].
Chamberlain and Chadwick (1972) observed that deposition velocity of Lycopodium spores to dry soil was similar to sedimentation velocity regardless of wind speed.
In canopies with high leaf-area index, high turbulence within the canopy at high wind speeds can cause increased transfer of particles to the lower canopy and ground level, resulting in greater sedimentation at these levels and greater deposition velocities than would be predicted from sedimentation velocity alone (Legg & Price, 1980).
