Description During the first stage of the project work on the Indian Deep-Sea Environment Experiment (INDEX), the abundance and distribution of deep-sea benthos were surveyed in the Central Indian Basin for the collection of baseline data. The deep-sea community of the sediment was characterized by a moderately high standing crop and diverse fauna. The macrofaunal component was dominated by polychaetes (100% prevalence) and peracarid crustaceans, whereas the meiofauna was dominated by nematodes and harpacticoid copepods. The results of this study conform to the general distribution reported elsewhere. The macrofaunal abundance showed an inverse relation to the abundance of polymetallic nodules. However, the relation between meiofaunal vertical distribution and the vertical profile of the total organic matter and total labile matter was positive
