Sonar image quality evaluation using deep neural network

Sonar technology plays an important role in the development of marine resources and military strategy. Due to the bad quality of underwater acoustics channels, the sonar images collected by sonar technology equipment are easily affected by various kinds of distortions. To obtain high-quality sonar images, the authors devise a novel dual-path deep neural network (DPDNN) to measure the quality of sonar images. In these two paths, the authors use a batch normalization layer to reduce the training time and use the skip operation to speed up the feature extraction . Based on the above two operations, the authors extract the microscopic and macroscopic structures of sonar images, respectively. Finally, a global average pooling layer and a fully connection layer are used to connect the above two paths. Experiments show that the authors' DPDNN achieves significant improvements in prediction performance and efficiency. The source code will be published in the near future.

小尺度海域空间评价单元划分技术研究——以福建省东山湾为例

科学合理的海域空间评价单元划分是各类海洋空间监测、评价、规划和管理的基础工作，对于保护海洋生态环境，实现海洋资源的可持续开发利用具有重大现实意义。然而，海洋的流动性、开放性、边界模糊性等特征，导致海洋空间评价单元划分较陆地而言更为复杂、困难。以福建省东山湾为例，提出一种适用于小尺度海域的空间评价单元划分技术方案，通过从化学属性、物理属性、生物学属性三个方面构建海域空间生态属性划分指标体系，进行空间分类评价，运用插值、叠加分析等GIS技术将东山湾划分为67个基本空间评价单元。研究结果不仅能为进一步划定东山湾海洋空间规划提供技术支持，同时为其他小尺度海域生态监测、评价、规划和管理提供科学参考。;For the sustainable development and utilization of marine resources, and protection of marine ecological environment, coastal countries have successively implemented marine spatial planning (MSP). MSP is considered as an important marine management tool, which is an indispensable part of marine ecological civilization construction in China. Scientific and reasonable division of marine spatial units is the basic work of marine spatial monitoring, evaluation, planning and management, which is of great practical significance for the protection of marine ecological environment and the sustainable development of marine resources. However, the characteristics of the ocean, such as mobility, openness and boundary ambiguity, make the division of marine spatial units more complex and difficult than that of land. In this study, we collect a large number of data from environmental monitoring sites in Dongshan Bay. Based on the comprehensive and detailed data which can capture ecological environment status, we propose a technical scheme of spatial evaluation units division which is suitable for fine-scale sea areas. The scheme constructs the index system for the division of marine spatial evaluation units based on the physical, biological and chemical elements. Combined with GIS technology such as interpolation and spatial overlay analysis, Dongshan Bay is divided into 67 basic spatial evaluation units, which is a more accurate and scientific division of marine spatial units. On the basis of marine spatial units, local government can carry out the marine spatial monitoring, evaluation, planning and management. The marine environmental protection strategies and marine exploitation activities can be formulated for the sea areas with different environmental endowments by considering the local conditions. This division approach can not only provide technical support for the MSP of Dongshan Bay, but also can be a supplement of spatial units division approach for marine spatial monitoring, evaluation, planning and management. This division approach is suitable for fine-scale sea areas, but it is also applicable to large and medium-scale sea areas where complete and detailed environmental monitoring data can be obtained. The technical scheme of marine spatial units division proposed in this study has a wide application prospect.

Evaluation and Driving Force Analysis of Marine Sustainable Development Based on the Grey Relational Model and Path Analysis

With the rapid development of the marine economy, the demand for marine resources development and the pressure on marine environmental protection are gradually increasing. It is critical to evaluate and analyze the driving forces of marine sustainable development in order to promote the coordinated development of the marine economy, resources and environment. Taking Jiangsu Province of China as an example, this paper constructs an evaluation index system for marine sustainable development from the three aspects of marine economy, resources and environment, and calculates the weight of the variation coefficient for each indicator. Based on the grey relational model, the average value of the relational degree, calculated by the average value method of correlation coefficients and the weighting method, is then used to evaluate the status of marine sustainable development in this province. The comprehensive index model is used to analyze the dynamic trend of the evolution of marine sustainable development. The driving forces of marine sustainable development are analyzed by the path analysis method combined with the average values of the grey relational degree for each indicator. This analysis found that the marine sustainable development in 2016 and 2012 was good, the situation in 2007 was bad, and the remaining years were intermediate. Compared with the previous years, the optimal conditions of 2008 and 2012 were obvious. The main driving factors of marine sustainable development are cargo throughput of coastal ports, economic losses caused by storm surges in coastal areas, the area of marine nature reserves in coastal areas, coastal wind power generation capacity, and marine biodiversity.

Isolation and characterization marine bacteria capable of degrading lignin-derived compounds.

Lignin, a characteristic component of terrestrial plants. Rivers transport large amounts of vascular plant organic matter into the oceans where lignin can degrade over time; however, microorganisms involved in this degradation have not been identified. In this study, several bacterial strains were isolated from marine samples using the lignin-derived compound vanillic acid (4-hydroxy-3-methoxybenzoic acid) as the sole carbon and energy source. The optimum growth temperature for all isolates ranged from 30 to 35°C. All isolates grew well in a wide NaCl concentration range of 0 to over 50 g/L, with an optimum concentration of 22.8 g/L, which is the same as natural seawater. Phylogenetic analysis indicates that these strains are the members of Halomonas, Arthrobacter, Pseudoalteromonas, Marinomonas, and Thalassospira. These isolates are also able to use other lignin-derived compounds, such as 4-hydroxybenzoic acid, ferulic acid, syringic acid, and benzoic acid. Vanillic acid was detected in all culture media when isolates were grown on ferulic acid as the sole carbon source; however, no 4-hydroxy-3-methoxystyrene was detected, indicating that ferulic acid metabolism by these strains occurs via the elimination of two side chain carbons. Furthermore, the isolates exhibit 3,4-dioxygenase or 4,5-dioxygenase activity for protocatechuic acid ring-cleavage, which is consistent with the genetic sequences of related genera. This study was conducted to isolate and characterize marine bacteria of degrading lignin-derived compounds, thereby revealing the degradation of aromatic compounds in the marine environment and opening up new avenues for the development and utilization of marine biological resources.
