Ocean noise Ocean noise, stemming from human activities, disrupts crucial natural sounds essential for marine animals. In recent years, heightened awareness of marine environmental conservation has spurred extensive research on this issue. Many studies not only investigate noise sources but also assess its impact on marine organisms' communication, behavior, and physiology. Researchers employ metabolomics and bioscience techniques, along with passive acoustic monitoring that minimally affects marine life, to understand physiological changes in marine organisms, biodiversity, distribution, the soundscape, and trends in marine noise alterations. Brandon L. Southall (2024) notes significant progress in understanding how noiseexposure context affects behavioral responses, enhancing our knowledge of anthropogenic noise's impact on individual and group behavior. Methodological advancements have broadened the spatial and temporal scales of disturbance studies for various exposure scenarios in local populations. However, combined data from acute and chronic noise events suggest that 'all-or-nothing' thresholds are inadequate and inconsistent with avaiable contextual data. Significant differences between species, individuals, situational contexts, and temporal and spatial scales of exposure necessitate developing criteria for long-term, broad-scale impact assessments. Chiu et al. (2024) highlight that low-molecular-weight metabolites and metabolomics offer unprecedented insights into the physiological changes in marine organisms due to noise exposure. Metabolomics bridges the understanding of underwater noise as an environmental stressor and dissects the complexities of marine life responses. Integrating metabolomics with genomics and proteomics provides a multi-layered understanding of biological responses, allowing precise identification of genes, proteins, and metabolic pathways affected by noise. Emerging bioinformatics tools enhance data analysis, visualization, and interpretation, offering innovative insights into the subtle yet profound effects of underwater noise.
