Deep Sea Minerals Volume 1CDeep Sea Minerals Volume 1C
A physical, biological, environmental, and technical review, examine the geology and associated biology of the three principal deep sea mineral deposit types found in the Pacific Region. They also look at the environmental and technical aspects related to deep sea mineral extraction.

Examples of exploration tools Examples of exploration tools
Exploration for ferromanganese crusts involves the identification, delineation and evaluation of deep sea mineral resources and generally requires sophisticated, multipurpose research vessels using advanced technologies such as deep sea mapping equipment, remotely operated vehicles, photographic and video systems, and sampling and drilling devices.

Sea-floor ferromanganese crust mining system and related sources of potential environmental impact. Sea-floor ferromanganese crust mining system and related sources of potential environmental impact.
The operation of sea-floor production tools will increase levels of introduced noise, vibration, and light. There can be direct damage to other animals, sessile benthic fauna will be particularly vulnerable.

Concentration of cobalt, nickel, and other metals of potential economic importance in ferromanganese crusts Concentration of cobalt, nickel, and other metals of potential economic importance in ferromanganese crusts
Cobalt, the trace metal of greatest economic interest, can be up to 2 per cent, but usually averages 0.5 to 0.8 per cent by weight. Ferromanganese crusts contain, among other metals, the highest concentrations of the rare tellurium, which is used in the solar cell industry to produce thin-film photovoltaics – the best material for converting sunlight into electricity

Formation of Fe-Mn crusts Formation of Fe-Mn crusts
A wide array of metals and elements dissolved in ocean water are adsorbed (meaning to adhere to a surface) in large quantities onto the manganese and iron oxides. The main source of nearly all metals dissolved in seawater is erosion of the continents. The exception is manganese, which derives primarily from hydrothermal sources and mixes throughout the global ocean.

Location of Seamounts Location of Seamounts
n the Pacific Ocean there are more than 11,000 seamounts (57% of the global total) and 41 000 knolls, and many more might exist in uncharted waters. Many seamounts are within the Exclusive Economic Zone (EEZs) of Pacific Island states. Bathymetric map of the Pacific showing the location of seamounts.
