This chapter discusses current ecosystem responses to the input of whale detritus. It then estimates the effects of industrial whaling on the production of dead whales and speculates on the consequences of these changes for marine ecosystems. Finally, it proposes an experimental approach to test some of these speculations. Whale carcasses are end members in the spectrum of marine detritus, constituting the largest, most energy-rich organic particles in the ocean. Most great-whale carcasses sink essentially intact to the deep-sea floor, where they are recycled by a succession of scavenger, enrichment-opportunist, and sulfophilic assemblages. Although the flux of organic carbon in whale falls is small compared to total detrital flux, the massive energy concentrated in a whale fall can support a diverse deep-sea community.
