Bear Seamount (39° 55'N, 67° 30'W) is an extinct undersea volcano located inside the U.S. Exclusive Economic Zone south of Georges Bank. The fauna associated with the seamount...

The Th230/Pa231 activity ratio in 7 of 11 manganese nodules is less than 10.8, the theoretical production ratio of activities in the ocean. This finding indicates difierential...

Uranium concentrations in a large number of marine sediment samples of different types with world-wide spatial distribution have been determined using the rapid, precise and...

This report is Volume 1 in the series of reports entitled "Descriptions of W.H.O.I. rock dredge samples". This series represents a major effort to catalog and prepare initial...

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...

Kennecott Copper Corporation became interested in manganese nodules in part based on the publications of Dr. John Mero and work being done at Scripps Institution of...

Manganese nodules and crusts samples analyzed in this work were chosen to represent a range of marine environments both oceanic and epicontinental. They were analysed by...
