Design of a Marine Sediments Resistivity Measurement System Based on a Circular Permutation Electrode

Marine sediments are rich in mineral resources, organic resources, and microbial life. The study of marine sediments is of great significance for the development and utilization of marine resources and understanding the life process. Resistivity is the overall characteristic of the electrical conductivity of marine sediments. Measuring the resistivity of marine sediments is helpful to ascertain the marine geological structure, study the distribution of marine mineral resources, and evaluate the marine soil environment. Measuring the resistivity of marine sediments is of great significance to promote marine exploration. At present, the resistivity measurement device on the market can be directly used to measure soil and water on land, but if used to measure marine sediments, it will be disturbed by seawater temperature and pressure, resulting in large errors. In this paper, a high-precision pressure-maintaining transfer system of marine sediment resistivity measurement instrument based on circular permutation electrode is designed, which can measure the resistivity of marine sediment samples after pressure-maintaining transfer. At the same time, a new type of circular permutation electrode measurement method is proposed, which makes the resistivity value more accurate, reduces the length of the probe appropriately, and saves the cost. By measuring the resistivity of marine sediments, the type of sediments can be inverted, which provides a way of thinking about the promotion of the research and development and utilization of marine resources.

Lower Silesia

The Lower Silesia area in SW Poland is characterized by a geological structure that is conducive to mining activity. The exploitation of rock raw materials plays an important role in this sector of the economy. By the end of 2017, there were in total approximately 400 current concessions for the exploitation of rock raw materials in the analysed area (Polish Geological Institute, MIDAS database—Management and Protection System of Polish Mineral Resources). The conducted mining activity results in waste, which in the greatest amount occurs in the process of obtaining crushed road and construction aggregates, natural aggregates, carbonate raw materials for the cement and lime industry, as well as stone elements for construction and road engineering. At the end of 2016, the mining plants accumulated 26,569,600 Mg of waste. As part of the European Regions Toward Circular Economy (CircE) project, research was conducted on the volume and composition of the mining waste of rock raw materials in the years 2010–2016 within Lower Silesia. This research used the methods of statistical, descriptive and spatial analysis to identify mining plants with the highest potential for using their wastes. In the course of this study, 6 mining plants with the highest potential of using their waste for industrial production purposes were selected. In order to objectively select these plants, the methodology of qualitative multi-criteria analysis was developed, and 7 criteria were selected for assessing the economic potential of using waste from the mining of rock raw materials. An additional result of this research is a database and graphical presentation of changes in the spatial distribution of generated waste in the Lower Silesia region in the years ranging from 2010 to 2016.

AbstractMicroorganisms in marine sediments play major roles in marine biogeochemical cycles by mineralizing substantial quantities of organic matter from decaying cells. Proteins and lipids are abundant components of necromass, yet the taxonomic identities of microorganisms that actively degrade them remain poorly resolved. Here, we revealed identities, trophic interactions, and genomic features of bacteria that degraded 13C-labeled proteins and lipids in cold anoxic microcosms containing sulfidic subarctic marine sediment. Supplemented proteins and lipids were rapidly fermented to various volatile fatty acids within 5 days. DNA-stable isotope probing (SIP) suggested Psychrilyobacter atlanticus was an important primary degrader of proteins, and Psychromonas members were important primary degraders of both proteins and lipids. Closely related Psychromonas populations, as represented by distinct 16S rRNA gene variants, differentially utilized either proteins or lipids. DNA-SIP also showed 13C-labeling of various Deltaproteobacteria within 10 days, indicating trophic transfer of carbon to putative sulfate-reducers. Metagenome-assembled genomes revealed the primary hydrolyzers encoded secreted peptidases or lipases, and enzymes for catabolism of protein or lipid degradation products. Psychromonas species are prevalent in diverse marine sediments, suggesting they are important players in organic carbon processing in situ. Together, this study provides new insights into the identities, functions, and genomes of bacteria that actively degrade abundant necromass macromolecules in the seafloor.

AbstractThe marine ecosystem has become the hotspot for finding antibiotic-producing actinomycetes across the globe. Although marine-derived actinomycetes display strain-level genomic and chemodiversity, it is unclear whether functional traits, i.e., antibiotic activity, vary in near-identical Streptomyces species. Here, we report culture-dependent isolation, antibiotic activity, phylogeny, biodiversity, abundance, and distribution of Streptomyces isolated from marine sediments across the west-central Philippines. Out of 2212 marine sediment-derived actinomycete strains isolated from 11 geographical sites, 92 strains exhibited antibacterial activities against multidrug-resistant Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. The 16S rRNA and rpoB gene sequence analyses confirmed that antibiotic-producing strains belong to the genus Streptomyces, highlighting Streptomyces parvulus as the most dominant species and three possible new species. Antibiotic-producing Streptomyces strains were highly diverse in Southern Antique, and species diversity increase with marine sediment depth. Multiple strains with near-identical 16S rRNA and rpoB gene sequences displayed varying strength of antibiotic activities. The genotyping of PKS and NRPS genes revealed that closely related antibiotic-producing strains have similar BGC domains supported by their close phylogenetic proximity. These findings collectively suggest Streptomyces' intraspecies adaptive characteristics in distinct ecological niches that resulted in outcompeting other bacteria through differential antibiotic production.

Abstract The geological structure and the occurrence of mineral resources in the Silesian Upland in a significant way influenced the development of industry and caused transformation of every landscape element, among others changes in relief and therefore the formation of anthropogenic landforms. The paper focuses on environmental aspects of relief transformation in the Silesian Upland. The author described aesthetic, geomorphological, hydrological, climatological, pedological and biological aspects on the base of representatives of two groups of landforms–consciously created by human being and being an unintentional effect of human activity (of secondary character). All analysed landforms are new elements in relief, in majority of cases being in disharmony with their neighbourhood. They are alien to the landscape and disturb the equilibrium in the nature. It was proved that they strongly influence water and climatological conditions and soil cover. But sometimes the anthropogenic landforms can be perceived as advantageous for the nature, especially in case of subsidence depressions because of development of aquatic and hydrophilous species and in case of spoil tips due to spontaneous development of vegetation cover. The nature easily adapts to new environmental conditions (process of natural succession and independent introduction of species for new habitats). In these terrains the increase in biodiversity was observed.

Rare earth metals are an important strategic resource. Due to scarce reserves, and large consumer demand, it is facing the crisis of resource depletion. Marine are the largest deposits sites in the world. In the long growth history, marine autogenic sedimentary mineral, such as polymetallic nodules, crusts with large quantities, not only contain the enrichment of Mn, Fe, Co, Cu, Ni and other valuable metals, but also contain extremely rare earth elements (REE) in the crust. Thus, in the process of developing marine mineral resources, Mn, Fe, Co, Cu, Ni and other metals are used, while it is possible for the development and utilization of the associated rare earth mineral. Marine may become a new field of rare earth resources development.

Mineral resources are the material basis of national economic construction and people's living standards, In China more than 80% of the energy and industrial raw materials from the mineral resources, and its total ranked third in the world, while the per capita amount is less than half the world average, and is very resource scarce countries. Its reserves of mineral resources are limited, supply is limited, is a non-renewable resource. With the continuous development and utilization constantly dropped, it has exhaustible. Under certain technical conditions, continued exploitation of resources of a mineral resource reserves will gradually approaches zero. In other words, when the abundance of minerals continue to reduce, development costs continue to rise, so that the quantity demanded tends to zero, the state reached exhaustion.
