Digital Twins in the Marine Industry

The ocean holds abundant resources, but the utilization of those resources for the marine economy presents a complex and dynamic industrial situation. Exploring sustainable development in this industry is of practical value, as it involves the rational use of marine resources while protecting the environment. This study provides an innovative review of the current application status of Digital Twins Technology (DTT) in various sectors of the marine industry, including the ship-building industry (SBI), Offshore Oil and Gas Industry, marine fishery, and marine energy industry. The findings reveal that DTT offers robust support for full life cycle management (LCM) in SBI, including digital design, intelligent processing, operation, and error management. Furthermore, this work delves into the challenges and prospects of DTT application in the marine industry, aiming to provide reference and direction for intelligent systems in the industry and guide the rational development and utilization of marine resources in the future.

Preface

Impact of whale-watching vessels on humpback whale calling behavior on an Icelandic foraging ground during the Covid-19 pandemic

Whale-watching vessels contribute to elevated ambient sound levels in marine habitats. The reduction in maritime tourism activities during the Covid-19 pandemic provided an unprecedented opportunity to study the acoustic response of marine mammals to noise associated with whale-watching activities. In this study, we used acoustic recordings, visual observations, and Automatic Identification System data to determine the changes in humpback whale Megaptera novaeangliae calling behavior associated with whale-watching vessels on a foraging ground in Skjálfandi Bay, Iceland. We compared pre-pandemic summer months (2018) with pandemic (2020) conditions to quantify reductions in vessel activity and determine changes in calling behavior. Broadband ambient sound pressure levels were low in both years (median ~90 dBRMS (25-1300 Hz) re 1 µPa). During the Covid-19 pandemic (2020), the number of whale-watching trips was reduced by 68.6%. The number of humpback whale call detections increased nearly 2-fold. Ambient sound pressure levels stayed the same. We found that humpback whales reduce their calling effort in the presence of vessel sound independent of the overall ambient sound. As whale-watching vessel traffic rebounds and continues to grow, demonstrating behavioral responses should inform management plans such as vessel codes of conduct and marine spatial planning.

Traditional Knowledge of Marine Resources and Their Relations to the Coastal Community's Economic Well-Being in Peninsular Malaysia

This study was conducted to analyse the practice of associated use of traditional knowledge (TK) on marine resources as new sources of wealth to enhance the economic well-being of the coastal communities. This study employed a qualitative research approach with a total of 117 respondents in Peninsular Malaysia. Convenience and purposive sampling methods were used to identify potential respondents and thematic analysis for the data analysis. The data was gathered through telephone interviews during the Movement Control Order (MCO) in Malaysia due to the COVID-19 pandemic. The results of the study reveal that the associated use of traditional knowledge on marine resources does play an essential role in the economic well-being of coastal communities. This was assessed through the perspective of living standards and livelihood improvement. The potential of TK based on marine resources illustrates the opportunity for this practice to become a valuable economic resource and create employment opportunities among coastal communities to generate a sustainable source of income. This study can also change modern society's perception of the importance and benefits of TK based on marine resources. The implications of this study can be viewed from the theory, practice, and policy. Future studies could be expanded to the Borneo region of Malaysia to gather different perspectives, and a quantitative approach could be used to gather more extensive opinions. © 2022 WITPress.

Implementing SDG 14 Under Principles, Ethical Values, and Environmental and Economic Justice for Small-Scale Artisanal Fishermen in Costa Rica

In Costa Rica, as in other countries, vulnerability and marginalization experienced by small-scale artisanal fishermen, fisherwomen, and mollusk collectors are the result of the absence of a human rights‐based approach to marine conservation and development in the coastal areas. Usually non-formality, absence of tenure and access rights, bad health services, and low education compared to other productive sectors are part of what fisherfolks experience. This commentary shares how working in a long-term and integral way with these communities and incorporating a human rights‐based approach strengthens the contributions that the sector provides toward the sustainable use of the fishing resource of their marine territories with dignity, equity, and justice, especially in the context of SDG 14, the Ocean Decade, and 2022 as the International Year of Artisanal Fisheries and Aquaculture. Born during the COVID pandemic, the initiative of a fair and equitable Sea Market for the fishing products of these small-scale communities supported by CoopeSoliDar RL and the Marine Responsible Fishing areas and marine territories of life network in Costa Rica is today a concrete example of how a fair and just market can contribute positively to the objectives of sustainable development and the fundamental elements contained in the Convention on Biological Diversity, preservation of the natural environment, sustainable use, and fair and equitable distribution of benefits.

Reference collection amidst COVID-19 pandemic: fish, crustacea, and mollusc of rumphius expeditions deposited in Ambon, Indonesia

Due to COVID-19, many scientists have to work remotely and have limited access to physical reference collections. This situation has highlighted that providing online digital content is considered one of the most effective solutions. To make materials of reference collection more accessible to scientists or researchers, we here report the Rumphius expeditions (1973 – 1980) materials to Indonesia that still remain at the Ambon Research Station or now become reference collection of Centre for Deep-Sea Research, LIPI-Ambon, Indonesia. The morphological analyses of fish, crustacea, and mollusc collected during the Rumphius expeditions revealed: 34 species from 23 different genera of fish;21 species from 19 different genera of crustacea;and 60 species from 42 different genera of mollusc. This study demonstrates the value of reference collections as a resource in marine biology science and the important role of archivists in this current pandemic situation.

Transport Systems for Sustainability: Policy, Planning and Exploitation

There are several SDG targets directly linked to transport, including SDG 3 on health (increased road safety), SDG 7 on energy, SDG 8 on decent work and economic growth, SDG 9 on resilient infrastructure, SDG 11 on sustainable cities (access to transport and expanded public transport), SDG 12 on sustainable consumption and production (ending fossil fuel subsidies) and SDG 14 on oceans, seas and marine resources. The authors concluded that the construction of the new artery by the city centre, using appropriate technical solutions and traffic organization (tunnel, noise barriers, roundabouts, speed limit) likely contributed to an overall reduction in NO2 concentrations. Tsakalidis, Gkoumas, Grosso and Pekár present an overview of TRIMIS and its benefits as an integrated analytical tool that provides support to sustainable transport governance and decision-making. [...]it provides insights on current technology trends in the road transport domain with a focus on smart innovation and identifies emerging trends with a potential future impact through a dedicated case study, combining a techno-economic assessment with findings of a horizon scanning exercise. [...]we have four papers that focus on specific modes of transport—road and maritime:

It Is a Balancing Act: The Interface of Scientific Evidence and Policy in Support of Effective Marine Environmental Management

The marine environment is a complex system, and with growing human demand, the sustainable use of multiple marine resources is continually challenged. The increasing complexity of overlapping marine activities causes pressures on the environment. Here, we review the fundamental aspects for effective marine management, particularly the role of science and scientific evidence to inform marine policy and decision making. The outcomes of internal expert workshops were used to analyse currently applied marine management practices in the UK using four marine sectors in English waters based on the expertise: environmental impact assessments;dredge and disposal operations;marine protected areas;and offshore renewable energy. Strengths, weaknesses, and commonalities between these sectors were assessed in terms of their effectiveness for marine management. Finally, we make recommendations based on the outputs to better inform effective yet sustainable marine management. The importance of increasing accessibility to data, hypothesis-driven environmental monitoring, streamlining funding opportunities and ensuring effective dissemination of data to ensure scientific outcomes and achieve increased robustness of assessments is emphasised. We also recommend that assessment drivers align with the outputs and approaches should be holistic and engage with the public to ensure a shared understanding and vision.

Potentials of associated traditional knowledge on marine resources for economic and general well-being among coastal communities in Terengganu, Malaysia

This study was conducted to explore the potential of associated traditional knowledge on marine resources for the sustainability of economic and general well-being among coastal communities in Terengganu. Using a qualitative study, twenty-six interviews were conducted. The study used convenience and snowball sampling to identify the other potential participants who had knowledge and experience about the topic. The study used thematic analysis to identify the required themes according to the objectives. Drawing upon sustainable livelihood theory for data interpretation, the findings indicate that traditional knowledge of marine resources plays an essential role in achieving economic well-being for the coastal community in Terengganu. This is viewed from the aspect of increased living standards and improved health quality. Although exploration of traditional knowledge on marine resources is limited among the modern generation, the implications of this study highlight that identification of certain marine resources as traditional medicine for health problem solutions, selling fresh marine resources, and production of processed food from marine resources could offer ways to improve the economy of coastal communities. The study was carried out during the Covid-19 pandemic, which had limited the number of participants interviewed. Therefore, the sample size obtained is relatively small to find more significant results. Future studies can be expanded through quantitative approach methods among traditional medicine practitioners and other communities in different regions that use marine resources in their daily life. © 2021 The Authors.
