Lp. Madin et al., DISTRIBUTION AND VERTICAL MIGRATION OF SALPS (TUNICATA, THALIACEA) NEAR BERMUDA, Journal of plankton research, 18(5), 1996, pp. 747-755
Sampling near Bermuda by trawling and SCUBA diving yielded 16 species
of salps in August 1989 and March-April 1990. Several species occurred
in the surface waters only at particular times of the day, suggesting
diel vertical migrations on different schedules. At the time of sampl
ing. salps were present in low numerical abundances and constituted on
ly a small fraction of the total zooplankton biomass.
