Nandan, Secretary‐General, International Seabed Authority I am pleased to be here this morning and to see you attending this important workshop. Exploration, mining and processing technologies for developing polymetallic nodules resources in the Area have long been recognized as key components in their commercialization. We have assembled here in this beautiful city of Chennai for a workshop to take stock of the present status of the mining technology and the challenges that lie ahead. Last year when I visited NIOT and later had discussions in Delhi with Dr. P. S. Goesl, Secretary, Ministry of Earth Sciences and Dr. S. K. Das, advisor to the ministry and former member of the LTC and an active contributor to the work of the Authority, the idea of a workshop on technology development was raised. Since then we agreed to hold this meeting. I thank the government of India for inviting the International Seabed Authority to hold this workshop in India, and particular in Chennai, and for agreeing to host the event at NIOT. It is the untiring efforts of the Ministry of Earth Science and the group at the NIOT which have resulted in this workshop becoming a reality. I would like to thank the Minister of Earth Science, Dr. Kapil Sibal; the Secretary of the Ministry, Dr. P. S. Goesl; Dr. S. K. Das and their colleagues in Delhi and here at the NIOT. I would like to thank Dr. Kathiroli, whom you just heard, he is the Director of the National Institute Of Ocean Technology; also Dr. M. A. Atmanand, he is in charge of technology development of seabed mining and their colleagues at NIOT. All of them have contributed to making this workshop possible. Ladies and gentlemen this is not the first time we have met to discuss the state of seabed mining technology. In January 1994 the preparatory commission for the ISA and for the International Tribunal for the Law of the Sea convened a meeting of a group of technical experts to review the state of deep seabed mining and to make an assessment of the time when commercial production might be expected to commence. In discharging its mandate the group of technical experts took into account information notes submitted by five of the registered pioneer investors at that time: India; IFREMER of France; Yuzhmorgeologia (of the Soviet Union at the time), now Russia; DORD of Japan; IOM ‐ Inter Ocean Metal ‐ based in Poland. We took into account the annual periodic reports submitted by the six pioneer investors at the time and the publicly‐available information. The Committee was of the view that the developments in the field of visual and actual sampling for nodules have been adequate to assess the resources. However, the technology needs to be adequately upgraded to get to the commercialization stage. The experts also concluded that in the field of deep seabed mining two of the basic design concepts have been abandoned or shelved; the continuous line bucket dredge and the shuttle system. The two systems that were being envisaged and developed in parts, included the collection 4 of polymetallic nodules by either a towed system or self‐propelled collector system and the lifting of nodules through a 5 km long vertical riser pipe utilizing using centrifugal pump or airlift. The collector system, to be operational in a high pressure and low temperature environment, while operating on soil of poor strength demanded special equipment components and material which needed to be tested in the actual deep seabed environment. However, it was noted that an integrated mining system, even on a pilot scale of long duration, has not yet been demonstrated. The expert committee also took stock of the nodule processing technology and concluded that though the progress in hydro and biometallurgy

    9. GEOCHEMICAL EXPRESSION OF EARLY DIAGENESIS IN MIDDLE EOCENE-LOWER OLIGOCENE PELAGIC SEDIMENTS IN THE SOUTHERN LABRADOR SEA, SITE 647, ODP LEG 1051 M. A. Arthur,2 W. E. Dean,3 J. C. Zachos,2 M. Kaminski,4 S. Hagerty Rieg,2 and K. Elmstrom2 ABSTRACT Geochemical analyses of the middle Eocene through lower Oligocene lithologic Unit IIIC (260-518 meters below seafloor [mbsf]) indicate a relatively constant geochemical composition of the detrital fraction throughout this deposi­ tional interval at Ocean Drilling Program (ODP) Site 647 in the southern Labrador Sea. The main variability occurs in redox-sensitive elements (e.g., iron, manganese, and phosphorus), which may be related to early diagenetic mobility in anaerobic pore waters during bacterial decomposition of organic matter. Initial preservation of organic matter was me­ diated by high sedimentation rates (36 m/m.y.). High iron (Fe) and manganese (Mn) contents are associated with car­ bonate concretions of siderite, manganosiderite, and rhodochrosite. These concretions probably formed in response to elevated pore-water alkalinity and total dissolved carbon dioxide (C02) concentrations resulting from bacterial sulfate reduction, as indicated by nodule stable-isotope compositions and pore-water geochemistry. These nodules differ from those found in upper Cenozoic hemipelagic sequences in that they are not associated with methanogenesis. Phosphate minerals (carbonate-fluorapatite) precipitated in some intervals, probably as the result of desorption of phosphorus from iron and manganese during reduction. The bulk chemical composition of the sediments differs little from that of North Atlantic Quaternary abyssal red clays, but may contain a minor hydrothermal component. The silicon/ aluminum (Si/Al) ratio, however, is high and variable and probably reflects original variations in biogenic opal, much of which is now altered to smectite and/or opal CT.

  • ECONOMIC ASPECTS of NODULE MINING Although Deep-Sea
    CHAPTER 11 ECONOMIC ASPECTS OF NODULE MINING J. L. MERO INTRODUCTION Although deep-sea manganese nodules were discovered over a'century ago by scientists of the HMS Challenger expedition, few analyses of the nodules for the economically significant elements such as nickel, copper, cobalt and molybdenum were made in those early days and no consideration was given to these deposits as a possible commercial source of metals until the early 1950's when the mining of the nodules was advocated as a possible source of manganese (Mero, 1952). As the result of a haul of nodules taken in relatively shallow water (900 m) about 370 km east of Tahiti on the western edge of the Tuamoto Plateau during the 1957-58 International Geophysical Year (the nodules contained about 2% of cobalt, a valuable metal at that particular time), a study was initiated by the Institute of Marine Resources of the University of California to determine if it might be economic to mine and process the nodules for their cobalt, nickel and copper contents. The results of that study were favourable' with respect to the technical and economic factors involved in mining and processing the nodules. All the research and development in this matter dates from the release of the report describing the results of that study (Mero, 1958). To the present time (1975) over $150 million* has been expended in the exploration of the nodule deposits and in the development of mining and processing systems. An additional $100 million is to be spent in the next few years in these activities.

Fac. Sci., Hokkaido Univ., Ser. IV, vol. 23, no. 1, July., 1991, pp. 41 -51 STUDY OF THE STRUCTURE MODEL OF TODOROKITE by Hiroyuki Miura (with 5 text-figures and 3 tables) Abstract The X - ray diffraction study of todorokite from Japan was carried out and appropriate struc­ tural model was calculated by Rietveld method. The calculation of the theoretical diffraction pattern was done for a layer structural model and the calculated results show that the layer model can explain the observed diffraction data. Some of the properties of todorokite such as superstructure or shrinkage of c-axis on heating can be explained by the layer model which con­ tains random H 20 between the [MnOs] layers. Introduction Todorokite is a manganese oxide mineral having H 20 in its structure. It was reported first from the Todoroki gold mine, Hokkaido, Japan (Yoshimura, 1934) . This mineral occurs as aggregate of fine acicular crystals. It also contains H20, Ca, Ba and Mg. The X -ray powder diffraction data of todorokite clearly show diffraction peaks of 9.6, 4.8, 3.2, 2.45 and 1.42 A. Since 1934 there has been many reports of todorokite like minerals from all over the world (Frondel, 1953; Frondel et aI. , 1960; Ljunggren, 1960; Straczek et aI., 1960; Faulring, 1961 ; Larson, 1962; Radtke et aI., 1967; Lawrence et aI., 1968; Harada, 1982; Siegel and Turner, 1983) .

  • Chennai District Origin of Chennai
    DISTRICT PROFILE - 2017 CHENNAI DISTRICT ORIGIN OF CHENNAI Chennai, originally known as Madras Patnam, was located in the province of Tondaimandalam, an area lying between Pennar river of Nellore and the Pennar river of Cuddalore. The capital of the province was Kancheepuram.Tondaimandalam was ruled in the 2nd century A.D. by Tondaiman Ilam Tiraiyan, who was a representative of the Chola family at Kanchipuram. It is believed that Ilam Tiraiyan must have subdued Kurumbas, the original inhabitants of the region and established his rule over Tondaimandalam Chennai also known as Madras is the capital city of the Indian state of Tamil Nadu. Located on the Coromandel Coast off the Bay of Bengal, it is a major commercial, cultural, economic and educational center in South India. It is also known as the "Cultural Capital of South India" The area around Chennai had been part of successive South Indian kingdoms through centuries. The recorded history of the city began in the colonial times, specifically with the arrival of British East India Company and the establishment of Fort St. George in 1644. On Chennai's way to become a major naval port and presidency city by late eighteenth century. Following the independence of India, Chennai became the capital of Tamil Nadu and an important centre of regional politics that tended to bank on the Dravidian identity of the populace. According to the provisional results of 2011 census, the city had 4.68 million residents making it the sixth most populous city in India; the urban agglomeration, which comprises the city and its suburbs, was home to approximately 8.9 million, making it the fourth most populous metropolitan area in the country and 31st largest urban area in the world.

Received 1 December, 2018; Accepted 11 February, 2019 In the Southern Indian ‘State of Tamil Nadu’, the traditional Jallikattu sport involving young men competing against bulls is described as one of the ancient living sports in the modern era. Based on petitions by animal rights groups, the Supreme Court of India banned the ancient sport of Jallikattu in 2014 on the grounds of animal cruelty. The ban of this traditional sport ignited protests culminating in a large-scale 15-day movement across the state from January 8 to 23, 2017 with a massive mobilization on the world’s second longest beach, the Marina in the state capital of Chennai. Largely propelled by the youths, the ban was perceived as an attack on Tamil culture and identity. The anger was directed at foreign animal rights activism and an unstable political situation gained momentum with media attention. This resulted in the promulgation of a central Act to overturn the ban and facilitate conduct of the sport. This paper examines the role of social media rallying the public and activism against the Jallikattu ban.

  • Petrogenesis of Ferromanganese Nodules from East of the Chagos Archipelago, Central Indian Basin, Indian Ocean
    ELSEVIER Marine Geology 157 (1999) 145±158 Petrogenesis of ferromanganese nodules from east of the Chagos Archipelago, Central Indian Basin, Indian Ocean Ranadip Banerjee a,Ł, Supriya Roy b, Somnath Dasgupta b, Subir Mukhopadhyay b, Hiroyuki Miura c a Geological Oceanography Division, National Institute of Oceanography, Dona Paula, Goa 403004, India b Department of Geological Sciences, Jadavpur University, Calcutta, 700032, India c Department of Geology and Mineralogy, Faculty of Science, Hokkaido University, Sapporo, 060, Japan Received 28 May 1997; accepted 24 July 1998 Abstract Deep-sea ferromanganese nodules occur over a large area and on many different sediment types of the Central Indian Basin, Indian Ocean. Selected samples were studied to determine their chemical and mineralogical compositions and microstructural features. Repeated laminations of variable thickness, alternately dominated by todorokite and vernadite, are characteristic of these nodules. These laminae show, on electron microprobe line scans, corresponding interlaminar partitioning of Mn±Cu±Ni and Fe±Co. The bulk chemical compositions of these nodules plot in both the hydrogenetic and early diagenetic ®elds on the Fe±Mn±(Ni C Cu C Co) ð10 ternary diagram. The binary diagram depicting the covariation of Mn C Ni C Cu against Fe C Co shows two distinct parallel regression lines, one delineated by nodules from terrigenous, siliceous ooze and siliceous ooze±terrigenous sediments and the other by nodules from red clay, siliceous ooze±red clay and calcareous ooze±red clay. An increasing diagenetic in¯uence in the nodules with the nature of the host sediment types was observed in the sequence: terrigenous ! siliceous ooze and red clay ! siliceous=calcareous ooze±red clay.
