Summary: This study analyzed the mineralogical and chemical compositions of ferromanganese crusts collected from two seamounts in the Vietnam continental margin, central South China Sea. The results showed that the composition and morphology of the studied crusts were different from the Prime Crust Zone crusts in the Pacific Ocean and partially similar to the ferromanganese crusts and nodules from the northern South China Sea. The formation of the crusts was influenced by various mechanisms, including the input of detrital material, precipitation of iron and manganese oxides from seawater, upwelling, and high coastal primary productivity. The growth rate of the crusts was calculated to be 11 +/- 1 mm/Myr and 4.4 +/- 0.5 mm/Myr, indicating a formation period of around 1.5 million years ago.

Summary: This study elucidates the reaction processes of aqueous Fe(II) with ferromanganese nodules and discusses its impact on the exchange of Fe atoms and the formation of magnetite in the nodules. The observed Fe(II)-induced recrystallization of nodules is expected to play a significant role in influencing the geochemical behavior of elements in nodule-enriched soils.

Summary: The ferromanganese deposit is a marine mineral resource rich in Mn, Fe, Co, Ni, and Cu. Its growth process is influenced by the guyot environment and seawater geochemical characteristics. Studying the texture morphology, microstructure, mineralogical features, and geochemical features of the ferromanganese crusts deposits is important for understanding their formation process and properties.

Summary: The article discusses the credit for the discovery of ferromanganese nodules in the World Ocean, which has been firmly attributed to the Challenger expedition for a century. A counterclaim regarding the Nordenskiold expedition on Sofia in 1868 was brought up, but historical evidence and report analysis confirmed that the credit indeed belongs to the Challenger expedition in 1873.

Summary: This study characterizes the FeMn crusts of the Rio Grande Rise in the southwest Atlantic Ocean and demonstrates that they are composed of manganese oxides, iron oxyhydroxides, magnesian calcite, and carbonate fluorapatite. The results show that regions with thicker crust layers have a higher content of critical elements.

Summary: This study presents new major, trace, and REE data for ferromanganese nodules in the Central Indian Ocean Basin (CIOB) and explores their genetic aspects, classification, growth rate, nature of host sediments, and influence of REE in nodule formation. The study reveals that nodules in the CIOB are mainly hydrogenetic or diagenetic in origin, and their metal enrichment is primarily influenced by diagenetic processes.

Summary: The strain CW126-A03 increased ion concentrations of Fe, Mn, and other metal elements in solutions, accumulating metal ions on the cells' surface and forming ultra-micro sized mineral particles, even crystalline minerals. This highlights the potentially important role of biologically induced mineralization (BIM) in ferromanganese nodule formation and indicates the potential of microorganisms in nodule formation.

Summary: This paper reviews the research progress and achievements related to ferromanganese nodules (FMNs), including their formation mechanisms, variations in micromorphology, elemental contents and mineral compositions, and their effects on nutrient and heavy metal adsorption and fixation. The future research areas highlighted include determining the age and formation stages of FMNs using numerical dating techniques, establishing FMN evolution models, and investigating the processes and mechanisms of nutrient and heavy metal fixation and reactivation by FMNs through controlled experiments and isotope techniques.

Summary: This study reveals the enrichment mechanism of cobalt in Fe-Mn nodules and identifies its association with manganese and iron phases. The enrichment of iron favors the formation of Fe-Vernadite in cobalt-rich nodules, thereby facilitating higher cobalt contents.

Summary: The Andaman Sea has ferromanganese deposits as crusts and nodules formed by hydrogenetic and hydrothermal processes. These deposits are enriched in certain metal elements and have higher contents of Li, Ba, and some base metals in nodules compared to crusts. Some samples from Invisible Bank are ironstones enriched in Fe, Cr, Ni, and As formed by hydrothermal solutions. The rapid precipitation of Fe-Mn oxides is a result of metal ions from volcanic-hydrothermal sources and oxygen supply from intermediate waters.

Summary: This study investigated the relationship of Fe and Mn differentiation within nodules to their mineralogy, highlighting differences in mineralogy based on hydromorphic conditions. Nodules in shallow groundwater soils had more developed fabric and goethite prevailed, while nodules in flooded soils showed smaller size and a higher frequency of non-crystalline hydrous Fe oxides. The study suggests that different hydromorphic conditions may influence the Fe-oxyhydroxide mineralogy within nodules, particularly in the crystallization process.

Summary: The study analyzed 32 years of high-resolution atmospheric reanalysis data to determine the atmospheric responses to sea surface temperature (ST) fronts in the Bering Sea and Chukchi Sea. In the Chukchi Sea, the horizontal gradient and Laplacian of ST become noticeable in October and November, while an ST contrast develops in the winter in the Bering Sea. The study also demonstrated the pressure adjustment mechanism and confirmed the vertical mixing mechanism in both seas.

Summary: A comprehensive study of twelve ferromanganese nodules from the Philippine Sea depths of 4400 to 6000 m revealed different controls on element enrichments. Selective enrichment of metal elements in seawater is similar to typical hydrogenetic nodules, while enhanced supply of iron hydroxide due to calcite dissolution led to a dilution effect on Co, Ni, and Mn but an enrichment effect on REE + Y and Fe in nodules near topographic highs close to the carbonate compensation depth. Diagenetic Mn supply resulted in a dilution on Co and REE + Y but enrichment on Ni, Cu, Li, and Mn on seafloor nodules. Growth rate was found to be a major determinant for the correlations of Co and REE with Fe-oxyhydroxides in these Philippine Sea nodules, as confirmed by micro-layer analyses.

Summary: The distribution of rare-earth elements in ferromanganese deposits from the southeastern Laptev Sea is influenced by the composition and formation process of the deposits. The ore part of the deposits consists mainly of iron hydroxides, leading to deficiency in Ce and enrichment in middle REEs, while the (alumino)silicate part is related to bottom sediments and controls scandium content.
