Innovations in marine technology and potential needs for Arctic governance

The Arctic is a region of major significance in the Earth system,particularly important for global climate and international maritime governance.As human activity,relying on manufactured equipment,steadily increases in the Arctic,technological innovations for marine equipment must support the gradually more stringent requirements for future Arctic governance.In this review,four categories of innovations are analyzed,namely:innovations driven by traditional thinking,innovations for environmental protection,innovations for practical application,and innovations for observing information systems.Two examples of international regulations,the Polar Code(adopted in 2014)and the International Standard for Arctic offshore structures of the International Organization for Standardization(ISO 19906,first published in 2010),are selected to illustrate successful international cooperation efforts for Arctic marine innovation.This work provides a basis for discussion on technology development,governance efficiency,and international cooperation in the Arctic.

Coordination Mechanism and Empirical Research on Marine Science Technology Innovation and Marine Eco-civilization:A Case Study of Coastal Areas of China

Marine science technology innovation provides power and guarantees for marine eco-civilization construction,which provides direction and material support for marine science technology innovation.Therefore,the coordinated development of the two is of great significance to the marine economy sustainable development in China’s coastal areas.On the basis of clarifying the connotations of marine science technology innovation and marine eco-civilization in China’s coastal areas from 2006 to 2019,the mechanism for their coordinated development was analysed.A comprehensive indicator system based on the connotation of the two was constructed,and the coordinated development relationship was empirically tested using the coupled coordination model and the panel vector autoregressive(PVAR)model.The results show that:1)the level of China’s coastal marine science technology innovation continues to improve,gradually forming the core of the development of marine science technology innovation in the north,east and south of Shandong,Shanghai and Guangdong;the level of marine eco-civilization development fluctuating upward trend,showing obvious spatial differentiation characteristics.2)The degree of coordination of marine science technology innovation and marine eco-civilization is growing over time.There is no causal relationship between marine science technology innovation and marine eco-civilization in the northern marine economic circle,but there is a two-way causal relationship between the two in the eastern and southern marine economic circles.3)Marine eco-civilization shows a significant positive and continuous impact on marine science technology innovation,and marine science technology innovation shows a long-term,continuous,fluctuating,and lagging impact on marine eco-civilization.The overall role of marine eco-civilization on marine science technology innovation is dominant,and there are significant differences in the impact effects of the two major marine economic circles.

Technical development of operational in-situ marine monitoring and research on its key generic technologies in China

In China,operational in-situ marine monitoring is the primary means of directly obtaining hydrological,meteorological,and oceanographic environmental parameters across sea areas,and it is essential for applications such as forecast of marine environment,prevention and mitigation of disaster,exploitation of marine resources,marine environmental protection,and management of transportation safety.In this paper,we summarise the composition,development courses,and present operational status of three systems of operational in-situ marine monitoring,namely coastal marine automated network station,ocean data buoy and voluntary observing ship measuring and reporting system.Additionally,we discuss the technical development in these in-situ systems and achievements in the key generic technologies along with future development trends.

Empirical Research on the Influence of Marine High-end Human Resources on Marine Knowledge Innovation——With Organizational Incentive and Technological Innovation as Mediating Variable

The main purpose of this paper is to explore the intermediary role of policy incentives and marine technological innovation in marine high-end human capital promoting marine knowledge innovation.Previous studies on the impact of marine high-end human capital on marine knowledge innovation mainly focused on the direct impact of marine high-end human capital on marine knowledge innovation,while ignoring the role of intermediary variables.Based on 512 sample survey data from 138 organizations in 16 coastal cities of China,this paper uses structural equation model to examine the relationship between high-end human capital and policy incentives,technological innovation and marine knowledge innovation.The research shows that marine high-end human capital has an impact on marine knowledge innovation through policy incentives and marine technology innovation.Policy incentives and marine technology innovation play a full intermediary role in the relationship between marine high-end human capital and marine knowledge innovation.

Decarbonizing in Maritime Transportation: Challenges and Opportunities

As global warming caused by greenhouse gases grows (GHGs) into a global environmental threat, carbon dioxide emissions are drawing increasing attention in these years. Among all emission sources, transportation is a major contributor to climate change because of its high dependence on fossil fuels. The International Maritime Organization (IMO) has therefore been promoting the reduction of fuel usage and carbon emissions for container ships by such measures as improving shipping route selection, shipping speed optimization, and constructing clean energy propulsion systems. In this paper, a review of the impact of carbon dioxide emissions on climate change is presented;the current situations of carbon dioxide emissions, decarbonizing methods, IMO regulations, and possible future directions of decarbonizing in the maritime transportation industry are also discussed. Based on the result, it is found that in the case that non intelligent ships still occupy the vast majority of operating ships, the use of new energy as the main propulsion fuel has the defects of high renewal cost and long effective period. It is more likely to achieve energy conservation and emission reduction in the shipping industry in a short period of time by using intelligent means and artificial intelligence to assist ship operation. .
