Manganese nodules were selected from various areas of the Pacific, Indian and Atlantic ocean. They were analysed using a mercury vapour discharge technique. The minimum...

A selection of manganese nodules and crusts from he Australian marine region have been analysed for their metal content using atomic absorption spectroscopy. From 1983 until...

In 1978 during cruise CK-78(2) of the R/V Machias scattered manganese nodules were recovered from three stations in the Samoa Basin and abundant nodules from five stations in...

Fifteen manganese nodules from the Australian region have been analysed by the Bureau of Mineral Resources (BMR) from the Department of Minerals and Energy, Australia. These...

142 manganese nodules and crusts from sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). From 1983 until...

The manganese crust was retrieved from station 1052 during the 14th cruise of the R/V Dmitry Mendeleev. The station is located in Hess Deep in the axis of the Galapagos...

Uranium was measured in manganese nodules by alpha-ray spectroscopy after grinding and dissolution. The study included the separation of various rinds (layers) in the rind of...

This cruise was undertaken as part of the CCOF/SOPAC Work Programme CCSP-1/CK-1 (Sea bed investigation for manganese nodules in oceanic areas adjoining Cook Islands),...

16 manganese nodules and crusts from 11 sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using atomic absorption spectrophotometry (AAS). Samples...

23 manganese nodules and crusts from 17 sites in the Pacific Ocean were analyzed at Scripps Institution of Oceanography using X-ray emission spectrometry (XES). Samples were...

Iron-manganese crusts were chosen from existing collections in order to cover as wide an area and depth range as possible. Sampling was concentrated in the Central Pacific...

The study reported here involved the analysis of 12 rare earth and 13 minor elements in 13 nodules from the S.W. Pacific; 1 nodule from equatorial N. Pacific (DOMES Site C) as...

A gravelly sand deposit at 103 m depth on the summit region of Mount Palinuro, a seamount approximately 100 km off the Italian west coast, is made up of a mixture of manganese...

The continental slope and rise, east of Newfoundland, accommodates two distinct gravel populations. The upper slope (300-700 m depth) population is characterized by unstained,...

Analyses of the total alpha radioactivity distribution in 31 North Pacific manganese nodules yield an average growth rate of 6.8 ( 2) mm /m.y. Samples from a single box core...

Radiolarians from box cores and gravity cores indicate that Quaternary sediment covers the sea floor at DOMES Sites A, B, and C; however, at Sites A and B dissolution-resistant,...

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 September-October 1982, a joint German-French project to explore the Mazagan (El Jadida) escarpment and plateau was carried out with the French submersible sp 3000 Cyana ....

The aim of the sedimentological program of Leg ANT-X/2 was to densify the existing sample network in the area of the Weddell Sea and the Lazarev Sea, or fill the gaps in...

On a previous R/V Polarstern cruise ANT-VIII/5 (1989/90), a deep-sea area in the central Weddell Sea was investigated along geophysical and bathymetrical transects. As a result,...
