Marine Infrastructure Detection with Satellite Data—A Review

A rapid development of marine infrastructures can be observed along the global coasts. Offshore wind farms, oil and gas platforms, artificial islands, aquaculture, and more, are being constructed without a proper quantification of these human activities. Therefore, effective monitoring is required to maintain transparency towards environmental standards, marine resource management, inventorying objects, and global security. This study reviews remote sensing-based approaches to offshore infrastructure detection over the past 12 years. We analyzed 89 studies from over 30 scientific journals, highlighting spatial and temporal trends, methodological approaches, and regional and thematic research foci. Our results show a significant increase in research interest, especially since 2019. Asia, and especially China, is the predominant focus region in terms of first authorship, funding, and areas of investigation. Aquaculture is the most studied infrastructure, followed by platforms, offshore wind farms, and artificial islands. Gaofen, Sentinel, and Landsat are the most used satellite sensors for detection. The apparent shift towards automated detection methods, especially Deep Learning algorithms, reflects advances in computer vision. This study highlights the key role of earth observation in the field of off-shore infrastructure detection, which can contribute towards outlining effective monitoring practices for marine activities, as well as highlighting important knowledge gaps.

Blue Economy from Perspective of Al-Qur'an

This research concludes that from the Al-Qur'an perspective, the maritime concept with a blue economy perspective is an integral approach, where the utilization of marine resources, which are referred to as al-Bahr and al-yam in the Al-Qur'an, needs to integrate several aspects interrelated maritime affairs. Reduction of one maritime aspect can result in ineffectiveness in dealing with the complexity of maritime problems as a whole.The framework used in this research includes the following aspects:First, Aqidah: Humans are seen as caliphs who are responsible for the universe that Allah rules. Second, Sharia: Maritime natural resource utilization activities must be in accordance with the principles of Islamic law. Third, Morals: Improvement with adaptive innovation for the efficiency of natural resources, fair distribution, and consumption that does not damage or waste natural resources.This research supports the views of several figures such as Robert Maltus, Langdon Gilkey, Seyyed Hossein Nasr, Donella H. Meadow, Arne Naess, Edith Brown Weiss, and Gunter Pauli, who emphasize the need for wise management of natural resources for sustainability. The research method used is a qualitative method with the Tafsir Maudū'i (thematic) interpretation method.This research differs from the views of several figures, such as Hugo Grotius, Adam Smith, David Ricardo, Immanuel Kant, and Garret Hardin, who have different views regarding natural resource management. Thus, this research proposes a holistic approach based on Islamic values in viewing and managing marine resources to achieve economic and environmental sustainability.

MuLA-GAN: Multi-level attention GAN for enhanced underwater visibility

The underwater environment presents unique challenges (color distortions, reduced contrast, blurriness) hindering accurate analysis. This work introduces MuLA-GAN, a novel approach leveraging Generative Adversarial Networks (GANs) and specifically adapted Multi-Level Attention for comprehensive underwater image enhancement. MuLA-GAN integrates Multi-Level Attention within the GAN architecture to prioritize learning discriminative features crucial for precise image restoration. These relevant features encompass information on local details within image regions leveraged by spatial attention and features at various scales across the entire image captured by multi-level attention. This allows MuLA-GAN to identify and enhance objects, textures, and edges obscured by underwater distortions while also reconstructing a more accurate and visually clear representation of the underwater scene by analyzing low-level information like edges and textures, as well as high-level information like object shapes and global scene information. By selectively focusing on these relevant features, MuLA-GAN excels at capturing and preserving intricate details in underwater imagery, which is essential for various marine research, exploration, and resource management applications. Extensive evaluations on diverse datasets (UIEB test, UIEB challenge, U45, UCCS) demonstrate MuLA-GAN's superior performance compared to existing methods. Additionally, a specialized bio-fouling and aquaculture dataset confirms the model's robustness in challenging environments. On the UIEB test dataset, MuLA-GAN achieves exceptional Peak Signal-to-Noise Ratio (PSNR) (25.59) and Structural Similarity Index (SSIM) (0.893) scores, surpassing Water-Net (24.36 PSNR, 0.885 SSIM). This work addresses a significant research gap in underwater image enhancement by demonstrating the effectiveness of combining GANs with specifically adapted Multi-Level Attention mechanisms. This tailored approach offers a novel and comprehensive framework for restoring underwater image quality, providing valuable insights for accurate underwater scene analysis. The source code for MuLA-GAN is publicly available on GitHub at https://github.com/AhsanBaidar/MuLA_GAN.git

The Role of UNCLOS 1982 in Maintaining and Protecting the International Marine Environment

The disposal of nuclear waste in the Sea of Japan is a complex and controversial issue where it involves aspects of international law and the international environment. Japan, as one of the largest nuclear waste-producing countries, has faced pressure to manage that waste in a way that complies with international legal principles and environmental norms. International law, such as the United Nations Convention on the Law of the Sea (UNCLOS), provides a framework for the management of marine resources, including waste disposal issues. However, the lack of clarity in international regulations regarding nuclear waste creates challenges in determining the limits of state responsibility and obligations. From an international environmental perspective, nuclear waste disposal can have long-term detrimental impacts on marine ecosystems and human health. Sustainability and sustainability of marine ecology must be a primary consideration in decisions regarding nuclear waste disposal. Meanwhile, various international conventions and agreements such as the Espoo Convention and the Aarhus Convention emphasize the importance of public participation in environmental decision-making. Therefore, the involvement of civil society in the decision process regarding the disposal of nuclear waste in the Sea of Japan is essential to ensure representation of public interests and concerns. This research aims to find out and analyze Japan's actions in dumping nuclear waste into the Pacific Ocean. The problem formulation in this research is: what is the role of UNCLOS 1982 in maintaining and protecting the international marine environment? This research was written using the normative juridical research type, which includes examining legal conflicts, legal vacancies, or vague norms.

Larval dynamics suggest phenological strategies and positive effect of marine protected areas controlling indigenous and non-indigenous crab populations

The early life of most decapod crustaceans takes place in the water column as larvae before they settle in benthic habitats. The spatial and temporal variability in the settling of larval stages offers valuable insights into the potential recruitment of natural populations. To explore this, we studied megalopa assemblages at various segments of coastline on El Hierro and Lanzarote islands, both within and outside the Marine Protected Areas (MPAs) of each island. The study spanned four consecutive oceanographic periods in the Canary Islands (NW Africa), employing light traps for sample collection. The low number of recorded species suggested that light traps exhibit selectivity, particularly for megalopae belonging to Portunidae and Grapsidae. El Hierro, which experienced warmer sea surface temperatures, displayed higher megalopa abundance values than Lanzarote and distinct larval assemblages was observed between these two islands. Similarly, we identified significant variations in abundance and species composition between stratified and mixing seasons. These seasonal differences were influenced by the dominance of Achelous hastatus, Percnon gibessi, and Cronius ruber during the stratified season. In Lanzarote, C. ruber was not recorded during the mixing season, suggesting that the colder conditions there may constrain its reproduction. Interestingly, we observed that species traditionally harvested from the intertidal zone for human consumption (Plagusia depressa) or used as bait for recreational fishing (Pachygrapsus spp. and P. gibessi) exhibited higher megalopa abundances within the MPAs. In contrast, we noted lower megalopa densities of the non-indigenous species C. ruber within the protected areas. These results indicate a positive effect of MPAs controlling indigenous and non-indigenous crab populations. Moreover, the study provides novel data, showing that light traps are suitable for monitoring the temporal occurrence, abundance, and spatial distribution of non-indigenous and commercially exploited species. This is key for adopting an ecosystem-based approach to manage marine resources.

Mapping the distribution and dynamics of coastal aquaculture ponds using Landsat time series data based on U2-Net deep learning model

ABSTRACT The extraction of coastal aquaculture ponds from remote sensing images is affected by the effect of ‘same object with different spectrums’ and ‘different objects with same spectrums’. The U2-Net deep learning network is able to capture more contextual information from different scales to solve this problem and is suitable for salient object detection. This study proposed a remote sensing information extraction model of coastal ponds based on U2-Net deep learning network, completed the remote sensing information extraction of coastal aquaculture ponds in Zhoushan Archipelago from 1984 to 2022, analyzed the spatiotemporal evolution of coastal aquaculture ponds in Zhoushan Archipelago. The results showed that the developed model was more accurate with a precision rate of 96.12%, a recall rate of 95.43%, and an F1-measure of 0.96. During the study period, the area of the aquaculture ponds in the Zhoushan Archipelago demonstrated an increasing trend, expanding from 471.21 hm2 in 1984–3668.55 hm2 in 2022. In addition, over half of the aquaculture ponds had been active for more than 10 years. The method developed in this study is capable of rapidly and accurately mapping coastal aquaculture ponds, and thus is significant for the management of marine resources and promoting sustainable development.

Power and participation: A systematic review of marine protected area engagement through participatory science Methods

Marine Protected Areas (MPAs) are a critical part of the marine resource management community’s toolbox in seeking a sustainable and vibrant global ocean system. The processes of community engagement with MPAs, however, are rooted in pre-existing power dynamics inherent in environmental governance systems and influenced by historical contexts of colonialism. Marine governance has historically operated in a top-down manner, imposing exclusionary forms of conservation on local communities without affording them equitable power in the process. Meaningful engagement of community members in MPAs has been suggested as one of the key enabling conditions that drive successful marine protection. Specifically, participatory science methods have the potential to engage local communities, elevate local voices and expertise, and strengthen both local communities and scientific learning. This systematic scoping review assesses the peer-reviewed literature to understand the quality and nature of participatory science methods that have been used to engage communities in MPAs. The review highlights that, while participatory science methods are not uncommon in MPAs, they seldom challenge existing power dynamics. The results of this review show that power in MPA processes related to participatory science is generally retained by conventional researchers and MPA managers. Based on these findings, the authors provide recommendations to marine resource management researchers and practitioners to help the ocean governance community support greater power sharing with local communities through equitable and locally appropriate participatory science methods.

Different roles of the Amazon-Orinoco barrier on the genetic structure of two sardine genera from the Western Atlantic Ocean

Three sardine species of Harengula and one of Opisthonema (Clupeiformes, Clupeidae) are known in the Western Atlantic, where the Amazon-Orinoco plume has been recognized as a major biogeographic barrier, albeit permeable to larger and generalist species. Here we used mitochondrial cox1 gene DNA sequences to check the lineage delimitation of both genera, testing the influence of the Amazon-Orinoco barrier (AOB) and marine provinces on their phylogeographic structure. Results indicate that the two genera are differently affected by the AOB, including cryptic speciation in Harengula and population structure in Opisthonema. Harengula show a broad distribution in the Brazilian Province (BRA) distinct from H. clupeola and H. jaguana from the Greater Caribbean Region (GCR). Divergence time between Harengula from the GCR vs. BRA was estimated as about 2.4 Mya, which coincides with the period of increasing sediment and freshwater discharge of the Amazon River in the Atlantic. Results also indicate the existence of a single species of Opisthonema, albeit with population structuring related to the marine provinces. Since species of both genera are relevant to artisanal fisheries and the maintenance of oceanic ecosystems, these results may help in fisheries management of these important marine resources.

Advancing Sustainable Marine Exploration: Highly Efficient Photonic Radar for Underwater Navigation Systems under the Impact of Different Salinity Levels

The exploration of underwater environments for applications like environmental monitoring, scientific research, and surveillance has propelled the significance of underwater wireless navigation. Light waves have emerged as a promising solution, offering the potential to achieve the required data rates and propagation speeds. However, underwater optical wireless navigation faces challenges, particularly limited range. This research investigates a novel FMCW (frequency-modulated continuous wave)-based photonic radar system’s efficacy in detecting underwater vehicles across diverse salinity levels and distances. Numerical simulation evaluations reveal distinct signal-to-noise ratios (SNR) and detected power peaks corresponding to varying salinity levels, demonstrating the system’s sensitivity. At 5 g/L salinity, the detected power peaked at −95 dBm, decreasing to −105 dBm at 15 g/L. SNR analysis indicates robust detection within a 4 m range, with challenges emerging at extended ranges and higher salinity. Despite these challenges, the system shows promise for near-range underwater navigation, contributing to sustainable marine exploration by enhancing the accuracy and efficiency of underwater monitoring systems. This advancement aligns with the goals of sustainable development by supporting the protection of marine ecosystems, promoting scientific understanding of underwater environments, and aiding in the sustainable management of marine resources.

Fine‐scale diet data reveal spatial variation in predator–prey interactions in Norwegian fjords

Abstract Predator–prey interactions in time and space determine stock productivity, making them an important consideration when managing marine resources, rebuilding stocks or considering reopening a fishery. We analysed fine‐scale diet data from surveys conducted in 2009–2010 and 2018–2019 in three fjords in northern Norway with geostatistical models investigating how predation varied in space, time and between predator species. Our focus prey species was northern shrimp (Pandalus borealis), valuable both as a commercial resource and a major food source for other important species like Atlantic cod (Gadus morhua). Diet composition of fish predators differed clearly between fjords. While predator species and size were good predictors of shrimp predation, the relationships with bathymetry, prey density and geospatial variables were complex. Our study indicates that predation of forage species, such as shrimp, varies spatially in heterogenous fjord ecosystems. Shrimp consumption was not highest in the fjord with highest predator density, indicating a higher dependency of cod on shrimp in specific areas. Realized predation is a complex combination of predator and prey densities and predator ecology that differed in each of the three fjords. Synthesis and applications. Ignoring spatial variations in predator–prey interactions may lead to an inaccurate perception of stock productivity, suboptimal management and possibly unsustainable management targets. We recommend spatially explicit assessment and management for fish stocks where predator–prey interactions vary substantially in space, such as fjords and reefs.

Analysis of Policy Strategy for Empowerment of Fisherman in Teluk Village, Labuan Sub-District, Pandeglang Regency

The community empowerment approach is sought to provide guidance for the sustainability of the livelihoods and lives of the fishing communities of Teluk Village, Labuan District, Pandeglang Regency, especially after being hit by the tsunami (22/12/2018) and the Covid-19 pandemic. Ecosystem preservation also requires commitment from stakeholders. The policy strategy is the government's task that needs to be analyzed, while the community has strong social capital, as a form of survival in facing opportunities, challenges and threats in the management of marine and fishery resources. This study aims to analyze the policy strategy for empowering fishermen in Teluk Village, Labuan District, Pandeglang Regency. The key theory used is the concept of strategy according to Hunger-Wheelen (2003: 9), through observing the external environment to describe opportunities and threats, then observing the internal environment of the organization to describe strengths and weaknesses known as Strengths, Weaknesses (weaknesses). Opportunities (opportunities), and Threats (threats). The approach used in this research is descriptive qualitative. Through this approach it is intended to be able to take a full picture of various phenomena that aim to describe, summarize various conditions, various situations or various social realities of empowering the fishing community in Teluk Village, Labuan District, Pandeglang Regency. The results of the study show that the policy strategy for empowering fishermen in Teluk Village refers to strengthening the internal and external sources of the Pandeglang Regency Maritime Service organization, including efforts in the field of empowering fishermen by carrying out various fisheries business development programs, carrying out fishermen technical guidance for business groups with fishermen. Furthermore, monitoring and evaluation, as well as carrying out reports. The suggestion that the researchers put forward is to increase various efforts to empower fishermen in the Bay Village by encouraging fishermen's involvement in accessing various institutional fishermen empowerment programs and revitalizing various facilities and infrastructure that require development and repair due to the tsunami disaster.

Sequential Treatment Application Robot (STAR) for high-replication marine experimentation

Marine organisms are often subject to numerous anthropogenic stressors, resulting in widespread ecosystem degradation. Physiological responses to these stressors, however, are complicated by high biological variability, species-specific sensitivities, nonlinear relationships, and countless permutations of stressor combinations. Nevertheless, quantification of these relationships is paramount for parameterizing predictive tools and ultimately for effective management of marine resources. Multi-level, multi-stressor experimentation is therefore key, yet the high replication required has remained a logistical challenge and a financial barrier. To overcome these issues, we created an automated system for experimentation on marine organisms, the Sequential Treatment Application Robot (STAR). The system consists of a track-mounted robotic arm that sequentially applies precision treatments to independent aquaria via syringe and peristaltic pumps. The accuracy and precision were validated with dye and spectrophotometry, and stability was demonstrated by maintaining corals under treatment conditions for more than a month. The system is open source and scalable in that additional treatments and replicates may be added without incurring multiplicative costs. While STAR was designed for investigating the combined impacts of nutrients, warming, and disease on reef-building corals, it is highly customizable and may be used for experimentation involving a diverse array of treatments and species.

Mitochondrial genome structure and composition in 70 fishes: a key resource for fisheries management in the South Atlantic

BackgroundPhylogenetic gaps of public databases of reference sequences are a major obstacle for comparative genomics and management of marine resources, particularly in the Global South, where economically important fisheries and conservation flagship species often lack closely-related references. We applied target-enrichment to obtain complete mitochondrial genomes of marine ichthyofauna from the Brazilian coast selected based on economic significance, conservation status and lack of phylogenetically-close references. These included sardines (Dorosomatidae, Alosidae), mackerels (Scombridae) croakers (Sciaenidae), groupers (Epinephelidae) and snappers (Lutjanidae).ResultsCustom baits were designed to enrich mitochondrial DNA across a broad phylogenetic range of fishes. Sequencing generated approximately 100k reads per sample, which were assembled in a total of 70 complete mitochondrial genomes and include fifty-two new additions to GenBank, including five species with no previous mitochondrial data. Departures from the typical gene content and order occurred in only three taxa and mostly involved tRNA gene duplications. Start-codons for all genes, except Cytochrome C Oxidase subunit I (COI), were consistently ATG, whilst a wide range of stop-codons deviated from the prevailing TAA. Phylogenetic analysis confirmed assembly accuracy and revealed signs of cryptic diversification within the Mullus genus. Lineage delimitation methods using Sardinella aurita and S. brasiliensis mitochondrial genomes support a single Operational Taxonomic Unit.ConclusionsTarget enrichment was highly efficient, providing complete novel mitochondrial genomes with little sequencing effort. These sequences are deposited in public databases to enable subsequent studies in population genetics and adaptation of Latin American fish species and serve as a vital resource for conservation and management programs that rely on molecular data for species and genus-level identification.

Presence of microplastic in target species of small scale fisheries and possible social implications on the local communities

Microplastic ingestion by marine fishes has been of particular interest, as many species are the target of commercial fisheries and, thus, have a strong connection with human health. Consumption of microplastic thru seafood is likely to have harmful effects on people globally but mainly on social groups that highly depend on fisheries for self-consumption. Here, we first aim to characterize the presence of microplastics in species targeted by small-scale fishers; and explore if the fish consumption of microplastic particles is associated with biological factors. Second, we applied semi-structured interviews to small-scale fishers to investigate, from a socio-environmental perspective, the potential social and environmental impacts of contamination by microplastics on the local communities. We found that commercially important fish families regularly contained microplastics in their tissues, and the consumption of microplastics by fish caught through traditional fishing gear depends on traits such as species mobility but the microplastic load also depended on the type of fishing gear used. Species with a wide home range had a higher load of microplastics than fish with a small home range but also seemed to be related to the fishing method. The observed differences in microplastic content on target species are likely to be transferred to humans in a non-random fashion. This work implies that microplastic pollution in commercial fish might represent an environmental and social issue that is not well understood by the fishing community in the Mexican Caribbean, with potential ramifications for marine resource management.

Harnessing economic tools for Indigenous climate resilience: Insights from Arctic marine resources

Economic tools remain under-used in addressing multiple challenges faced by indigenous communities in the rapidly changing Arctic. While there are multiple explanations for this under-use, perceptions that economic principles diverge from indigenous value systems and are rooted in Western paradigms limit the uptake of these tools to bolster resilience in the face of climate change. Nevertheless, Indigenous communities are expected to integrate their traditional systems with the historically imposed colonial systems of resource extraction to sustain their economies and community wellbeing that are challenged by environmental shifts and socioecological transitions. These changes manifest in resource use, availability and management and affect the ways Indigenous knowledge has traditionally guided resource exploitation decisions and practices. Using select examples, this paper argues that economic approaches to the management of marine resources have the potential to improve the well-being and resilience of indigenous Arctic communities. While more work is needed to tailor economic tools to the specific needs of indigenous people, the integration of resource economics and traditional approaches to resource management holds promise for strengthening Indigenous resilience in the face of the profound challenges posed by climate change.
