... to the mining platform is planned to be carried out by airlifting up the water - ore slurry. Water, accompanying particulate matter and dissolved substances comprising the fluid-particle mixture tailings, is to be ejected back into the ocean. Environmental studies for impact evaluation were conducted for water...

... and extraterrestrial material were the main contributors to the Os in the ocean relative to terrestrial material from late Cretaceous to Paleocene; Thereafter, the terrestrial material input increased gradually; after Oligocene, the terrestrial material input increased rapidly and became the main contributor...

... and mineral resources in the world's ocean, including sulphide, crust and nodules. In our paper we will present latest modification of different samplers, drilling and geotechnical rigs and multidisciplinary bottom systems. INTRODUCTION During last 20 years SC "SEVMORGEO" has specialized in design of new...

... ABSTRACT: An increasing interest is taken in developing the resources of the world oceans. During the last century, however, human activities were not always rational and sustainable. In this context, the energy and metal resources are characterised with a due consideration on the uneven...

... of the elements and their relation to mineral phases and show a linear dependance on the Fe content which are incorporated in the Fe/Mn oxide enriched phase. The data set has been statisticaly evaluated and compared with analogic sample assays from other nodule fields of the Atlantic, Indian and Pacific Oceans...

... sensor, conductivity sensor, autopilot system and so on. OKPO-6000, which was designed to safely reach the sea bottom of 6.000 meters deep ocean, successfully explored 2,300 meters sea bed in May. 1996 near the " Dok-Do" island in the " East Sea" of Korea. The specifications, system schematic...

... solubility In non-hydrate region and phase equilibrium diagrams or CO 2 waters and methane-waters systems. This conclusion results in reconsideration of assessments for various CO 2 sequestration methods in the ocean where the solubility extrapolated from non-hydrate region has been used...

... and ore particles and extensive damage to the sea floor (Lavelle et aI., 1981j Lavelle et a1., 1982j Thiel, 1991). Depending on the technology, the discharges will take place in different depths and intensity. upstream oil & gas ocean simulation zielke thiel lavelle standard deviation...

... Abstract: Although manganese nodules are observed in all world oceans, known reserves cannot be only criterion in future mine sites selection and sizing. Detailed and accurate depth data IS another major prerequisite. With the advent of multibeam swath mapping systems, our knowledge...
