Deep-sea mining: Current status and future considerations
(Springer, 2017)
Deep-sea minerals such as polymetallic nodule, hydrothermal sulphides, and ferro-manganese crusts have for long attracted attention as an alternative source of metals to terrestrial deposits. The occurrence of many of these ...
Alkaline phosphatase: An appraisal of its critical role in c-limited deep-sea sediments of central Indian Basin
(Taylor & Francis Group, 2017)
Alkaline phosphatase (ALP) is a hydrolase that releases phosphate, a crucial nutrient supporting formation of many macromolecules. The oligotrophic sediments of Central Indian Basin (CIB) were examined for the extent of ...
Bacterial activity in hydrogenetic ferromanganese crust from the Indian Ocean: A combined geochemical, experimental and pyrosequencing study
(Springer, 2017)
The Afanasiy-Nikitin Seamount (ANS) in the Equatorial Indian Ocean harbors hydrogenetic ferromanganese (Fe-Mn) crusts. It was hypothesized that the bacteria associated with the crust catalyze the precipitation of metal ...
Changes in depositional environment for the past 35 years in the Thane Creek, central west coast of India: Inferences from REEs, metals and magnetic properties
(Springer, 2017)
The role of diagenetic processes in influencing the behaviour of metals (Fe, Mn, Cu, Ni, Zn), rare earth elements (REEs) and environmental magnetic parameters in two sediment cores from a polluted creek environment (the ...
Discriminating the biophysical impacts of coastal upwelling and mud banks along the southwest coast of India
(Elsevier, 2017)
Coastal upwelling and mud banks are two oceanographic processes concurrently operating along certain stretches of the southwest (Kerala) coast of India during the Southwest Monsoon period (June-September), facilitating ...
Understanding heavy mineral dynamics using magnetic fingerprinting technique: A case study of North Maharashtra Coast, India
(Springer, 2017)
Environmental magnetic and grain size measurements were carried out on sand samples collected from nine sand pits along a 20-km coastal stretch of Arnala Beach, North Maharashtra, India. This study sets out to identify the ...
Assessment of distribution characteristics of polymetallic nodules and their implications on deep-sea mining
(Springer, 2017)
This chapter looks at the distribution characteristics of nodules and associated seafloor features so as to provide this information to the industry for designing a suitable mining system. Further, it also looks at different ...
Suspended sediment dynamics in Cochin estuary, West coast, India
(Springer, 2017)
An observational study was conducted in Cochin estuary to examine the relative impacts of tidal and river runoff forcing upon suspended sediment dynamics at different time scales. Time series measurements of salinity and ...
