Marine invertebrate surveys

Collaborators: Wilma Blom (Auckland War Memorial Museum); Fred Brook (Whangarei); Brett Stephenson (Whakatane)

This programme was jointly co-ordinated by Bruce Hayward and Margaret Morley (now deceased). The goal of this "hobby" research programme is to document the biodiversity and biogeography,and map the ecological distribution of the intertidal biota and inner shelf subtidal soft sediment benthos around the coast of northern New Zealand. All phyla are covered with emphasis on the molluscs, seaweeds, and echinoderms.
