dc.description.abstractData from more than 1000 locations in the Central Indian Ocean Basin (CIOB) where both bulk nodule chemistry and abundance were determined and utilized to study the relationship between grade and abundance of manganese nodule deposits. Grade is expressed as percentage nickel plus percentage copper (by weight), whereas the abundance of nodules on the seafloor is expressed as kg/m2. At each station 5-7 freefall grabs were deployed and the nodule recoveries in the samples were averaged arithmetically to arrive at an abundance value for that station. Similarly, samples 0.5 kg/m2 abundance were analysed for bulk chemistry and an average grade value (Ni + Cu) for the station is arrived at. Correlation coefficients were calculated between chemical variables and abundance
