In January 1989 we observed submarine eruptions on the summit of Macdonald volcano during a French-German diving programme with the IFREMER submersible Cyana. Gas-streaming of large amounts of CH4, CO2 and SO2 from summit vents, inferred from water c

Recent geochemical studies on ferromanganese deep-sea nodules have shown that the relationship between Mn and Fe allows us to differentiate between a diagenetic type (Mn/Fe ≥ 2.5) and a hydrogenetic type (Mn/Fe ≤ 2.5)1–7. Diagenetic and the low

Based on the analysis and comparison of metal content and growth rate determination by the 10Be method an empirical law has been developed to calculate the growth rate. Evaluating after 520 chemical analyses we have shown that the flux of Co into fer

Ferromanganese seamount crusts cover large areas of hard substrates of sea-floor edifices in the Central Pacific. They can be distinctly enriched in Pt and show Pt/Pd ratios which are several orders of magnitude greater than those orders of magnitude

The metal composition of oceanic ferromanganese deposits occurring in seamount regions (Line Islands chain and Mid-Pacific Mountains) varies with water depth and age. The results of metal determinations of carbonate plankton samples suggest that carb

The southeastern extension of the Austral Islands volcanic chain terminates near 29°S, 140°W at the active Macdonald Seamount. The ‘hotspot’ region near Macdonald consists of at least five other volcanic edifices each more than 500 m high, incl

Hydrogenetic ferromanganese deposits from seamount areas of the Central Pacific Basin should be seriously evaluated as sites for economic development. MIDPAC exploration cruises in 1981 and 1984 have shown that crust thickness varies between 0.5 and
