The serial coverage and indexing policies of Aquatic Sciences and Fisheries Abstracts (ASFA), Oceanic Abstracts, Biosis, and Georef were compared. Analyses indicated considerable overlap in serial sources in marine biology for ASFA, Oceanic Abstracts, and Georef. Biosis appeared to include the largest amount of material relevant to marine biology and Georef the largest relevant to marine geology. Oceanic Abstracts and Georef provided the most extensive general subject indexing, Biosis the most complete taxonomic indexing, and ASFA and Georef the easiest systems for geographic retrieval.

In recent years, China's marine industry has maintained rapid growth in general, and marine-related economic activities have continued to improve. The purpose of this research is to analyze the basic situation of China's marine economy development, identify the problems therein, forecast development trends and propose policy recommendations accordingly.

This research conducts a comprehensive and detailed analysis of the development of China's marine economy with rich data in diversified aspects. The current situation of China's marine economy development is analyzed from the perspective of scale and structure, and the external and internal development environment of China's marine economy is discussed. With the application of measurement and prediction method such as trend extrapolation, exponential smoothing, grey forecasting and neural network method, the future situation of China's marine economy development is forecasted.

In a complex environment where uncertainties at home and abroad have increased significantly, China's marine economy development suffers tremendous downward pressure in recent years. As China has achieved major achievements in the prevention and control of the COVID-19 epidemic, the marine economy development will gradually return to normal. It is estimated that the gross marine production value in 2022 will exceed 10 trillion yuan. China's marine economy will continue to maintain a steady growth trend in the future, and its development prospects will remain promising.

This research explores the current situation and trends of China's marine economy development and puts forward policy recommendations to promote the steady and health development of China's marine economy accordingly.

This is the fifth article on Science, Technology and Medicine (STM) databases in a continuing series of articles summarising and commenting on new database products. Two companion articles, one covering Social Science, Humanities, News and General (SSH) (Online & CDROM Review, vol. 19 issue 2), and the other covering Business and Law (BSL) (Online & CDROM Review, vol. 19 issue 3) will appear in the next two issues of this journal. The articles are based on the newly appearing database products in the Gale Directory of Databases. The Gale Directory of Databases (GDD) was created in January 1993 by merging Computer‐Readable Databases: A Directory and Data Sourcebook (CRD) together with the Directory of Online Databases (DOD) and the Directory of Portable Databases (DPD).

In our August issue we reviewed AERIAL SYNTHESIS, one of a series of films sponsored by the Department of Education and Science to interest school children in science as a possible career. In this issue we look at the other six films in the series, intended mainly for the thirteen‐ to fifteen‐year olds; films designed not to identify specific careers, but to show something of the breadth and fascination of scientific research as seen through the work of government research establishments.

Drought and salinity intrusion aggravated by climate change threaten agricultural livelihoods in Viet Nan's Mekong Delta. In response, authorities have built water management infrastructure for irrigation and salinity protection. This study assessed the impact of one such project, the Ba Lai dam in Ben Tre province, on the livelihoods of aquaculture farmers.

This study uses the Sustainable Livelihoods Framework to assess the impact of the Ba Lai dam on the livelihood capitals of 18 farming households in four communes, located both upstream and downstream of the dam.

The authors find that, apart from some positive effects, the dam has also brought negative environmental consequences, such as increased water pollution. The authors also find that farmers have responded to the changes by adapting their livelihood practices.

The samples were relatively small, encompassing four communes in Ben Tre province. On the other hand, this case study is instructive to the many ongoing infrastructure projects in the Vietnamese Mekong Delta.

The project have caused an increase in water-related social conflict.

The case of the Ba Lai dam provides a cautionary example for infrastructure-based water management plans, both in Viet Nam and more broadly. The study suggests the need to strengthen community participation and prioritize impacts of farmers' capital assets when constructing water management infrastructure for climate change adaptation.

Describes The Northampton Environmental Legacy Program, which links studies of the historic culture of Eastern Shore life with an awareness and understanding for the importance of environmental quality in this region. Over the six years’ duration of this pilot program, instructors have found that when this unique environmental/cultural instruction process is superimposed on an interdisciplinary blend of traditional high school teaching (math, science, language, literature, history, etc.), the students’ learning experiences are put into a context much more aligned to their life experiences. Program results have been significant. Because of the success of this program, a strong message is being sent to institutions of higher education. In preparation of future teachers, college/university curricula will need to offer an opportunity for developing exceptional skills in interdisciplinary teaching, so that new teachers can move seamlessly into high school programs already developed along the lines of the sustainable education model described here, and equally important will be the training of future teachers who can develop these new programs of education in sustainability at the high school level, where they do not yet exist.

This paper aims to demonstrate the principle and practical applications of hyperspectral object detection, carry out the problem we now face and the possible solution. Also some challenges in this field are discussed.

First, the paper summarized the current research status of the hyperspectral techniques. Then, the paper demonstrated the development of underwater hyperspectral techniques from three major aspects, which are UHI preprocess, unmixing and applications. Finally, the paper presents a conclusion of applications of hyperspectral imaging and future research directions.

Various methods and scenarios for underwater object detection with hyperspectral imaging are compared, which include preprocessing, unmixing and classification. A summary is made to demonstrate the application scope and results of different methods, which may play an important role in the application of underwater hyperspectral object detection in the future.

This paper introduced several methods of hyperspectral image process, give out the conclusion of the advantages and disadvantages of each method, then demonstrated the challenges we face and the possible way to deal with them.

Only 1% of the presently available 5000 database titles are relevant to marine biology and biotechnology. Nearly 60% of these are bibliographic in nature. There are almost no textual and numeric databases, which are the prime need of researchers. This paper presents a review of the major databases related to marine biology and biotechnology, with a discussion on the scope for textual and numeric databases.

Higher education system has a critical role to play in educating environmentally aware and participant citizens about global climate change (CC). And, as shown by the 21st Conference of the Parties of the UN Convention on Climate Change – COP 21, held in Paris in December 2015, there is still a path to be followed regarding the role played by universities in the negotiations and in influencing decision-making on a matter of such global importance. The purpose of this first study conducted within Portuguese (Europe), Mexican (Spanish-speaking North America University) and Mozambican (Africa) universities is to investigate higher education system students’ perceptions on CC.

The data were collected through a questionnaire aiming at characterising students from the socio-demography, and from their perceptions, motivations, attitudes and knowledge relating to the topic of CC. Statistical analysis was used to compare and characterise the three national groups under study.

This study did not show significant perception differences among the analysed subsamples, although there was a tendency for Mexican students to express lesser belief that CC was happening, and for Mozambicans to show a greater belief in CC issues and motivation to mitigate its effects which may be related to the specifics contexts. The results show that relevant differences among nationalities mostly concerned the magnitude of choices (e.g. most respondents of each nationality expressed interest in CC issues, but the magnitude of this expression differed according to nationality). The principal component analysis (second and third components) clearly embodied nationality profiles (discussed in the context of different cultures, educational structures and CC impacts).

Further research is warranted to understand the integration of CC into higher education curriculum to improve and target educational efforts to suit students’ needs.

How CC perceptions vary cross-nationally and how research studies that examine the integration of CC into higher education curriculum are areas for which more research is needed.

The results highlight the importance of socio-cultural dimensions of each country in relation to the understanding or perception of CC issues, namely, in what concerns aspects related with gender roles, age, active learning and citizenship. This study’s data evidenced that despite the surveyed students being familiarized with CC phenomena, this knowledge does not translate necessarily into concrete mitigation practices and behaviours.
