Deposition of Metalliferous Sediment Beneath a Brine Pool in the Atlantis II Deep, Red Seaovered to date on the seafloor and the only site given serious consideration for economic exploitation in the near future. The metalliferous deposit in the Atlantis II Deep is very different from other known submarine massive sulfide deposits forming on seafloor spreading centers. The Atlantis II de

Technologies for Geophysical Exploration on the Ocean Bottomhe ocean bottom are measured with a nuclear precession magnetometer deployed from a deeply towed vehicle. They reveal fine-scale crustal magnetization indicating geomagnetic field reversals and zones of varying lithology. Gravity anomalies of the ocean bottom are measured with a gravimeter placed on

Seafloor Electromagnetic Exploration Methods brief review of seafloor electromagnetic exploration principles and techniques is given, with an emphasis on the midocean ridge environment. The physical processes governing the electrical conductivity of rocks are discussed. Two types of seafloor electromagnetic exploration systems are then descri

An Electric Drill for Deep-Sea Coringdrills were hydrostatically powered and were principally employed on the Mid-Atlantic Ridge. However, these drills have been replaced by a deep-water version of an electric rock-core drill originally designed for continental shelf work. Part of the design philosophy behind these drills is operabilit

The whole length of the ridge is within 200 nautical miles of the United States and therefore falls within the recently proclaimed U.S. Exclusive Economic Zone. The recent discovery of hydrothermal sulfides at several locations along the
