摘要

The primary objective of this survey was to estimate absolute abundance ofseveral dolphin stocks. The secondary objective was to collect physical and biological oceanographic data in the area inhabited by these stocks. The oceanographic data are collected and analyzed to provide information about the effects of large-scale environmental variation on changes in estimated dolphin abundance. Oceanographic and other environmental variables, including chlorophyll a, nutrients, temperature salinity, zooplankton biomass and the occurrence of seabirds and other animals, are sampled concurrently with the dolphin sighting survey.
