Undamaged deep-sea manganese nodules were retrieved from a box core from the central North Pacific and quickly preserved in formaldehyde solution. Light and scanning electron...

In Costa Rica the manganese deposits are an integral part of the Nicoya ophiolite complex. They contain both primary mineralization and, due to weathering, small residual...

The results are discussed of a geophysical survey undertaken by R.R.S. Discovery II early in 1962 in an area centred on 29° 15'N, 25° 5'W at the western extremity of the...

Phosphorites with P2O5 contents up to 33% have been recovered from the eastern Atlantic between 6°N and 9°N. Formed from the replacement of shallow-water reef limestones of...

The cruise represented a continuation of our DoE research programme on oceanic radioactive waste disposal. A new instrument to be tried this time was the IOS deep-towed sonar...

he three-site Leg 64 Deep Sea Drilling transect at the tip of the Peninsula of Baja California straddled the transition from continental to oceanic crust. The outer site, 474,...

The objectives of RRS Discovery Cruise 156 was to provide a qualitative and quantitative description of the midwater and benthic ecosystems at a site on the Madeira Abyssal...

The main objective of the cruise was to study the sediments and sedimentary processes in an area known as Great Meteor East (GME) - part of a feasibility study into the ocean...

One of the main objectives of the International Phase of Ocean Drilling (IPOD) of the Deep Sea Drilling Project was to determine the geological, geochemical, and geophysical...

The objectives of RRS Discovery Cruise 153 were to provide information related to the testing for an oceanic disposal of high-level radiocative waste, to obtain a photographic...

SONNE 80a was a multidisciplinary expedition to map and sample intraplate volcanic activity associated with the proposed Easter "hotline" and its relation to the Orongo...

The SO-84 cruise from Las Palmas to Cape Town studied the underwater volcanism associated with the St Helena hotspot. Wide-spaced grid mapping of a region south and west of St...

Seven Alvin dives (14 km total) and numerous deep-towed camera traverses using ANGUS and NOAA camera systems provide dense coverage of a 12-km2 portion of the eastern wall of...

In addition to the large nodules of manganese dioxide that pave some regions of the ocean floor, much finely divided (<1 mm) manganese dioxide occurs within the sediment...

A detailed geophysical and geological survey of the Mariana Trough, an actively extensional back-arc basin, was conducted in 1976 and 1977 to provide data for selection of...
