This volume consists of eight reviews of topics in oceanography and marine biology: the use of visual imaging for marine biological and ecological research; the ecology of macro and microtidal estuaries; concepts, definitions, and assessment of habitat complexity for demersal marine fish; biodiversity and ecosystem consequences of the proliferation of artificial structures in the sea; the ecophysiological responses of corals to environmental stressors; the ecological impacts of marine disposal of mine tailings; the ecological roles of exploited sea cucumbers; and multidecadal spatial and temporal variation in phytoplankton diversity in south-eastern Australia.
