Historical logic and maritime cultural foundation of China's initiative of building a m... - 0 views

  •  
    Building a "Maritime Community with a Shared Future" (MCSF) is a maritime development concept with Chinese characteristics proposed by Chinese President Xi Jinping in 2019. It is based on the rich cultural tradition and unique historical value of China's maritime civilization. It aims to solve real ocean problems and has outlined the future direction of human ocean development from the perspective of China. The essence of the MCSF is an issue of both ocean cultural and development concepts. It is a conceptual issue that transcends specific national boundaries and regions and is based on how all of humankind, with common interests and common values, can develop in harmony with the oceans. It is not a covert discourse strategy adopted by China in order to realize its "maritime power" ambition, as occasionally described by some Western countries. Starting with an analysis of the essential nature and implications of maritime culture by Chinese researchers, this article clarifies and summarizes the interaction, exchange, and integration of Chinese maritime culture in East Asia from a historical perspective, and extracts the unique characteristics and values of Chinese maritime culture. From the perspective of human-sea interactions, the three historical stages, as well as the existing problems of transforming and upgrading human-ocean culture, are analyzed. The article also contrasts Chinese and Western maritime cultures and proposes to absorb the outstanding achievements of both Chinese and Western maritime civilizations into a common framework in order to fundamentally reverse the antagonistic human-sea relationship that has existed historically. Finally, we propose giving full play to the fundamental role of marine cultural exchange and integration and, through international cooperation on specific issues in the field of global ocean international relations, propose specific and feasible practical pathways to promoting the realization of the MCSF.

Anchor boxes adaptive optimization algorithm for maritime object detection in video sur... - 0 views

  •  
    With the development of the marine economy, video surveillance has become an important technical guarantee in the fields of marine engineering, marine public safety, marine supervision, and maritime traffic safety. In video surveillance, maritime object detection (MOD) is one of the most important core technologies. Affected by the size of maritime objects, distance, day and night weather, and changes in sea conditions, MOD faces challenges such as false detection, missed detection, slow detection speed, and low accuracy. However, the existing object detection algorithms usually adopt predefined anchor boxes to search and locate for objects of interest, making it difficult to adapt to maritime objects' complex features, including the varying scale and large aspect ratio difference. Therefore, this paper proposes a maritime object detection algorithm based on the improved convolutional neural network (CNN). Firstly, a differential-evolutionary-based K-means (DK-means) anchor box clustering algorithm is proposed to obtain adaptive anchor boxes to satisfy the maritime object characteristics. Secondly, an adaptive spatial feature fusion (ASFF) module is added in the neck network to enhance multi-scale feature fusion. Finally, focal loss and efficient intersection over union (IoU) loss are adopted to replace the original loss function to improve the network convergence speed. The experimental results on the Singapore maritime dataset show that our proposed algorithm improves the average precision by 7.1%, achieving 72.7%, with a detection speed of 113 frames per second, compared with You Only Look Once v5 small (YOLOv5s). Moreover, compared to other counterparts, it can achieve a better speed-accuracy balance, which is superior and feasible for the complex maritime environment.

Unification and Coordination of Maritime Jurisdiction: Providing a Judicial Guarantee f... - 0 views

  •  
    Maritime jurisdiction plays an important role in international trade and marine transport. It involves special kinds of rules that vary among different countries and legal systems. Thus, in international maritime jurisdiction, the coordination and settlements of jurisdictional conflicts are vital for the uniformity of international maritime law. This study provides a comparative analysis of maritime jurisdiction in international trade and marine transport. First, it introduces the concept, category, and legal characteristics of maritime jurisdiction based on historical sources. Then, we conduct a comparative analysis of the civil law system, common law system, international conventions, and Chinese maritime jurisdiction provisions, focusing on their differences and the existing legal problems. Among other suggestions for the improvement of the rules of maritime jurisdiction, this study proposes the unification and coordination of maritime jurisdiction, which could impact international trade and marine transport.

  •  
    Women constitute a mere 1.28 % of currently active seafarers. This is despite the concerted international efforts over the years to promote female participation in the maritime industry. Previous studies have identified several causal factors for the dismal representation of women in this sector. However, the current disruptions in the maritime workplace, mainly caused by the introduction of digital technologies and automation, have created a novel environment that limits the relevance of several previous research findings. This study aims to address that gap by investigating the factors impacting women seafarers' participation in the transition period leading to a technology-rich, highly automated future in the maritime industry. This paper is part of a larger qualitative study that looks at workplace participation and learning by seafarers. The data for this study was collected through semi-structured interviews and focus-groups conducted among seafarers and other maritime stakeholders. The thematic analysis of the data identified some physical, social, and psychological barriers that impede the workplace participation of women seafarers. Additionally, our analysis shows that the progressive adoption of Maritime Autonomous Surface Ship (MASS) and Shipping 4.0 will play an important role in improving women's participation in the shipping sector. However, to facilitate this, maritime policy makers and educators need to ensure a level playing field by providing gender-neutral access and opportunities to acquire skills and competences essential in a highly digitalised future workplace. Improving gender diversity is an essential step to align the maritime industry with the United Nations' Sustainable Development Goal 5.

The rule of law for marine environmental governance in maritime transport: China's expe... - 0 views

  •  
    Maritime transport is a major source of pollution of marine environment, which is the essential object in a series of international maritime legislations and various countries' domestic laws. Focused on protecting the marine environment, China has spent over 40 years developing the rule of law for marine environmental governance in maritime transport, including efforts made in legislation, law enforcement, and the judiciary. In this article, we attempt to examine China's experience and practice in the marine environment, explain the logic and consideration in relevant practices, and summarize China's paradigm for the rule of law for such governance. China has sought to resolve two major issues: the relationship between domestic and international law and the balance of interests between flag, coastal, and port states, offering a vivid model of marine environmental governance on which other countries can base their own legal systems. The findings reveal that with following and enforcing the international law of the sea, now China's domestic laws have form lawful authority on binding foreign vessels. China is continually strengthening the construction of its legislative system to harmonize inconsistencies and keep pace with international marine environmental law. To eliminate administrative inefficiency resulting from cumbersome procedures, China has reformed its maritime enforcement system by consolidating multiple administrations. China's independent maritime judicial system is meeting the demand to develop environmental specialization, enabling further exploitation of its profession in solving maritime environment cases and implementing environmental legislation.

Marine Observing Applications Using AIS: Automatic Identification System - @FrontMarineSci - 0 views

  •  
    The Automatic Identification System (AIS) is a real-time network of transmitters and receivers that allow vessel movements to be broadcast, tracked, and recorded. Though traditionally used for real-time maritime applications related to keeping track of vessel traffic for collision avoidance, there is increasing interest in using AIS data and the AIS platform for maritime safety planning, resource management, and weather forecasting. AIS data are being made tractable for alternative non-real-time applications like determining trends and patterns in vessel traffic and helping to prioritize where modern bathymetric surveys are needed to ensure safe maritime transit. The AIS is also being used for widespread transmission of critical environmental conditions information, such as sea state and weather, to mariners, forecasters, and emergency response providers. Several pilot projects are underway that demonstrate the capacity and promise of AIS data and the AIS platform to serve multiple purposes, providing overall maritime domain awareness while maintaining its most important objective of tracking vessels to aid safe, secure, efficient and environmentally sound maritime operations.

Ocean highways in the Western Mediterranean: Which are the areas with increased exposur... - 0 views

  •  
    Many marine megafauna taxa are tied to the sea surface for breathing which makes them vulnerable to vessel collisions. Sea turtles have developed efficient mechanisms to reduce surface time for breathing to a few seconds, but they can extend their surface periods to rest or to rewarm after diving into deep and colder waters. However, knowledge of collision occurrences is limited to data of turtles stranded along the coastline worldwide, whereas events occurring offshore go likely underestimated due to the sinking of carcasses. Here we performed a spatially explicit assessment to identify, for the first time, oceanic areas of higher exposure for sea turtles from maritime traffic in the Tyrrhenian Sea, Western Mediterranean. Satellite-tracking data were used to estimate utilization distributions of loggerhead turtles using Brownian bridge kernel density estimation. Maritime traffic density maps based on Automatic Identification System (AIS) data were extracted from open-access data layers, provided by the European Maritime Safety Agency, summarized, and used for the exposure analysis. Turtle occurrences were also investigated in response to vessel densities and seasonal patterns by fitting a generalized additive model to the data. Our results demonstrated that loggerhead turtles are potentially exposed to maritime traffic across the entire basin, especially in the easternmost part. The exposure varies among spring/summer and autumn/winter months. Highest turtle occurrences were found in regions primarily subjected to cargo, tanker, and passenger transportation. This study represents the first-ever effort to characterize the exposure of oceanic loggerhead turtles to maritime traffic and highlights oceanic areas of higher exposure where research and conservation efforts should be directed to understand the effective impact of this stressor on the species.

Verification and Modeling of the Maritime Channel for Maritime Communications and Navig... - 0 views

  •  
    This paper presents a geometric stochastic channel model designed for analyzing maritime communication and navigation services between moving ships using the C-band or sub-6 GHz spectrum, which aligns with the focus of emerging 5G networks on land. The channel model is validated through channel measurements conducted both on the sea and land. A software tool has been developed to integrate and analyze these measurements, which is included with this publication. The main challenge in developing the channel model for maritime services lies in the dynamic nature of the sea surface, leading to constantly changing reflection conditions due to varying reflectors and scatterers on the water. Additionally, the motion conditions of the transmitter and receiver on ships change in all three dimensions, depending on the sea state. To address these complexities, data from several measurement campaigns in diverse areas were collected. The analysis involved examining the propagation conditions over the sea with variations in sea surface roughness, antenna heights, and used bandwidths. Moreover, additional propagation conditions over nearby land were also taken into account. The study demonstrates that the changing antenna height on the ship, influenced by sea conditions, significantly affects the reflection and scattering conditions. The research aims to develop reliable, high-data rate, and broadband marine communication systems. Therefore, a measurement bandwidth of 120MHz was employed to derive the propagation model. This model not only offers absolute timing information but can also be used for time-based ranging or positioning systems. The proposed geometric stochastic channel model provides valuable insights into the complex maritime communication and navigation environment. By accounting for the continuously evolving sea surface and its impact on antenna height, the model offers a robust framework for studying and optimizing marine communication systems.

    Oceans are indispensable to our survival. Covering nearly 70 per cent of the planet, oceans feed us, provide us with jobs, and serve as the engine for much of the economy. But their vastness provides an opportunity for transnational organized crime to operate. As noted by Ghada WALY, "All countries, coastal and landlocked, rely on the security of the world's oceans." Ensuring maritime security is key to advancing sustainable development. Ahead of World Maritime Day on 28 September - and nearly two years after the opening of the first Port Control Unit (PCU) in Namibia, supported by the United Nations Office on Drugs and Crime (UNODC) - UNODC met one of the people on the frontlines of maritime law enforcement in Namibia, Officer Fransiskus NEGUMBO. Fransiskus is a Detective Warrant Officer with the Commercial Crime Unit, currently seconded to the Container Control Program in Walvis Bay, Namibia.

Maritime greenhouse gas emission estimation and forecasting through AIS data analytics:... - 0 views

  •  
    The escalating greenhouse gas (GHG) emissions from maritime trade present a serious environmental and biological threat. With increasing emission reduction initiatives, such as the European Union's incorporation of the maritime sector into the emissions trading system, both challenges and opportunities emerge for maritime transport and associated industries. To address these concerns, this study presents a model specifically designed for estimating and projecting the spatiotemporal GHG emission inventory of ships, particularly when dealing with incomplete automatic identification system datasets. In the computational aspect of the model, various data processing techniques are employed to rectify inaccuracies arising from incomplete or erroneous AIS data, including big data cleaning, ship trajectory aggregation, multi-source spatiotemporal data fusion and missing data complementation. Utilizing a bottom-up ship dynamic approach, the model generates a high-resolution GHG emission inventory. This inventory contains key attributes such as the types of ships emitting GHGs, the locations of these emissions, the time periods during which emissions occur, and emissions. For predictive analytics, the model utilizes temporal fusion transformers equipped with the attention mechanism to accurately forecast the critical emission parameters, including emission locations, time frames, and quantities. Focusing on the sea area around Tianjin port-a region characterized by high shipping activity-this study achieves fine-grained emission source tracking via detailed emission inventory calculations. Moreover, the prediction model achieves a promising loss function of approximately 0.15 under the optimal parameter configuration, obtaining a better result than recurrent neural network (RNN) and long short-term memory network (LSTM) in the comparative experiments. The proposed method allows for a comprehensive understanding of emission patterns across diverse vessel types under vari

Learning degradation-aware visual prompt for maritime image restoration under adverse w... - 0 views

  •  
    Adverse weather conditions such as rain and haze often lead to a degradation in the quality of maritime images, which is crucial for activities like navigation, fishing, and search and rescue. Therefore, it is of great interest to develop an effective algorithm to recover high-quality maritime images under adverse weather conditions. This paper proposes a prompt-based learning method with degradation perception for maritime image restoration, which contains two key components: a restoration module and a prompting module. The former is employed for image restoration, whereas the latter encodes weather-related degradation-specific information to modulate the restoration module, enhancing the recovery process for improved results. Inspired by the recent trend of prompt learning in artificial intelligence, this paper adopts soft-prompt technology to generate learnable visual prompt parameters for better perceiving the degradation-conditioned cues. Extensive experimental results on several benchmarks show that our approach achieves superior restoration performance in maritime image dehazing and deraining tasks.

The Worldwide Maritime Network of Container Shipping: Spatial Structure and Regional Dy... - 1 views

  •  
    Port and maritime studies dealing with containerization have observed traffic concentration and dispersion throughout the world. Globalization, intermodal transportation, and technological revolutions in the shipping industry have resulted in both network extension and rationalization. However, lack of precise data on inter-port relations prevent the application of wide network theories to global maritime container networks, which are often examined through case studies of specific firms or regions. This paper presents an analysis of the global liner shipping network in 1996 and 2006, a period of rapid change in port hierarchies and liner service configurations. While it refers to literature on port system development, shipping networks, and port selection, it is one of the only analyses of the properties of the global container shipping network. The paper analyzes the relative position of ports in the global network through indicators of centrality. The results reveal a certain level of robustness in the global shipping network. While transhipment hub flows and gateway flows might slightly shift among nodes in the network, the network properties remain rather stable in terms of the main nodes polarizing the network and the overall structure of the system. Additionally, mapping the changing centrality of ports confirms the impacts of global trade and logistics shifts on the port hierarchy and indicates that changes are predominantly geographic.

Declining Vigilance Threatens to Increase Martime Piracy - @Piracy_OBP - 0 views

  •  
    Despite reduced activity in the Western Indian Ocean Region in recent years, pirate networks responsible for the original Somali piracy crisis have sustained themselves through small-scale attacks and involvement in an array of maritime crimes. The spate of attacks over the last few months off the Horn of Africa, apparently triggered by perceived vulnerability in vessels transiting the area, may point to an elevated risk for a return of piracy. This is a key issue raised in the State of Maritime Piracy 2016, published today by Oceans Beyond Piracy (OBP). This annual reportanalyzes the human and economic impacts of maritime piracy and robbery at sea off the Horn of Africa, in the Gulf of Guinea, Asia, and for the first time, Latin America.
