Fig. 8. Drag coefficient (CD) versus water velocity
for all Chondrus. The line is CU, the exponential
decay function describing CD from 0.2 to 2.0 m
s1 (Eqn 5). Model parameters (±95% confidence
intervals) are: C
=0.75±0.03,
CR=0.87±0.12, ßC=0.42±0.08 m
s1 and R2=0.59.
Ucrit,C (1.56 m s1) is noted by the
arrow.
