Topic Information

Dear Colleagues,

This Topic will cover various aspects such as deep earth resource extraction, underground space utilization, deep sea resource development, and deep sea environment monitoring. Firstly, we will analyze the difficult problems encountered by deep earth engineering in resource extraction and underground space utilization, such as the mechanical properties of rocks under high-temperature and high-pressure environments, the stability of underground space structures, etc., and discuss the corresponding theoretical innovations and technological solutions.

Secondly, in the area of deep sea engineering, another important research direction, we will focus on the technical challenges in deep sea resource development, such as deep sea drilling, deep sea mining, deep sea energy development, etc., and introduce the related technological advances and theoretical innovations. Meanwhile, we will also discuss the importance of deep sea environmental monitoring, including the protection of deep sea ecosystems, early warning of deep sea geohazards, etc., and share the latest research results and application cases.

Black carbon, a short-lived climate forcer, has the dual impact of intensifying global warming and polluting the atmosphere. The further opening of Arctic shipping routes has resulted in a severe issue of black carbon emissions in this fragile region. The use of fuel, especially heavy fuel oil, in international shipping has generated enormous black carbon emissions, posing a serious threat to the climate in the Arctic and beyond. As the international community continues to pay attention to air pollution control and greenhouse gas emissions reduction, the need for effective global governance of black carbon emissions from Arctic shipping has become increasingly evident. This issue has emerged as a critical part of the broader effort to address ocean and climate governance through the lens of international law. Despite the efforts made by both the International Maritime Organization (IMO) and the Arctic Council (AC) to reduce black carbon emissions, the current international legal framework remains fragmented, with weak enforcement mechanisms and limited capacity for coordinated governance. The findings of this research underscore the importance of strengthening international legal instruments aimed at reducing black carbon emissions from Arctic shipping. In particular, there is a pressing need for the development of a dedicated international treaty with enhanced binding force to mitigate the ecological degradation in the Arctic, address global warming, and realize sustainable development goals.

Dense polymetallic nodule fields are found in different areas of the Pacific and Indian Oceans. However, limited knowledge exists about microbial diversity, processes and functions in deep-sea polymetallic nodule sediments. This study investigated microbial diversity, composition and function in sediments from various locations and depths in a western Pacific polymetallic nodule province. Sediment cores were collected, DNA extracted, and the V3–V4 regions of the 16S rRNA gene were sequenced using Illumina MiSeq. The test results show that the abundance and diversity of microbial communities in sediments from different sites vary significantly. The dominant microbial communities at the family level in the three sediment samples were all mainly Marinobacteraceae and Alcanivoracaceae. Sediment samples from core 1 had similar microbial structures and microbial community functions. Surface sediment had higher species richness, diversity and evenness than the middle layer. The dominant phylum at different depths was consistent. There was significant spatial heterogeneity in the microbial community within sediments from polymetallic nodule regions. This study expands on our knowledge of the spatial and vertical distribution of microbial community diversity beneath polymetallic nodules in deep-sea settings. Full article

The severe global hazards posed by marine microplastics must be given attention. This study evaluated the current international legal framework, and offers forward-looking recommendations for enhancing international law. The analysis began by examining the unique characteristics and profound impacts of marine microplastics, underscoring the necessity of a corresponding international regulatory regime. Through a thorough review of the existing global and regional legal instruments—both soft and hard laws—we identified key issues and challenges in the international legal response to marine microplastics, particularly in terms of legislation and enforcement mechanisms. The study emphasizes the urgent need for strengthened international legislation, including the potential development of a specialized international treaty, and calls for the enhancement of compliance mechanisms to effectively combat marine microplastic pollution and support the broader goal of sustainable development.

The energy of a focused acoustic field is quite concentrated, and the ability of an acoustic vortex formed by a concave focusing transducer array to capture objects in a flowing medium remains to be investigated. In this paper, the focused pressure distributions generated by an acoustic lens and a concave focused transducer array are firstly simulated, and the analyzed results show that the focusing effect of the latter is significantly better than that of the former. The acoustic gradient force and orbital angular momentum density distributions of the focused transducer array were investigated. A focused acoustic vortex tiny object capture system was built by simulating the hydrothermal column that forms in the seafloor hydrothermal zone. It was discovered that the forces affecting microorganisms and other small objects primarily consist of acoustic gradient force, viscous force, and additional mass force. The non-destructive capture of tiny seafloor objects was accomplished by adjusting the focused acoustic vortex’s propagation direction and the transducer array’s emitted power, thereby enabling more potential applications in ocean equipment.
