Archaeal and bacterial communities in deep-sea hydrogenetic ferromanganese crusts on old seamounts of the northwestern Pacific.

PLoS ONE, 2017
Deep-sea ferromanganese crusts are found ubiquitously on the surface of seamounts of the world's oceans. Considering the wide distribution of the crusts, archaeal and bacterial communities on these crusts potentially play a significant role in ...

Jurassic Fe-Mn macro-oncoids from pelagic swells of the External Subbetic (Spain) : evidences of microbial origin [PDF]

, 2010
Ferromanganesiferous macro-oncoids are distinctive from the External Subbetic Zone (Betic Cordillera, SE Spain) in relation to a major heterochronic unconformity, with a Middle Bathonian-Lower Oxfordian minimum hiatos and a Lowest Bathonian-Lowest ...

Integrated geochemical and biomarker signature of fast-growing Fe-Mn nodules from the Gulf of Finland, Baltic Sea

Frontiers in Marine Science
Ferromanganese (Fe-Mn) nodules, characterized by rapid growth and diverse morphologies, are widespread on the Baltic Sea seafloor. This study provides a comprehensive analysis of the bulk elemental composition, internal structures, and organic matter (OM)

Potential mitigation and restoration actions in ecosystems impacted by seabed mining [PDF]

, 2018
Mining impacts will affect local populations to different degrees. Impacts range from removal of habitats and possible energy sources to pollution and smaller-scale alterations in local habitats that, depending on the degree of disturbance, can lead to ...

The Formation of Ferromanganese Crusts From the Western Mariana Ridge and Implications for Deep‐Water Environment Since the Late Pliocene

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 5, May 2025.
Abstract Pacific Deep Water (PDW) plays a crucial role in the dynamics of the global thermohaline circulation. Understanding the evolution of the PDW is significant to reveal the global carbon cycle and its climatic responses. We present a comprehensive study of ferromanganese crusts from the Western Mariana Ridge (WMR), which includes mineralogical ...

Mechanisms for Growth of Marine Ferromanganese Nodules.

Oceanography in Japan, 1996
Megascopically, nodules are composed of nuclei and concentric shell layers. The hard surface of nuclei is necessary for the start of nodule formation. The concentric shell layers are formed by cyclic embedding of nodules in the sediment. During their embedding, 10 A manganates are precipitated diagenetically from interstitial water, which are rich in ...
