In conclusion, technological advances in remote sensing and GIS, AUVs, and data integration and modeling are significantly contributing to our understanding of the spatial and temporal dynamics of marine ecosystem structures in tropical oceans. These innovations are providing valuable insights and tools for the effective monitoring, conservation, and management of marine resources. 8 Challenges and Future Directions 8.1 Methodological challenges The study of spatial and temporal dynamics in marine ecosystems faces several methodological challenges. One significant issue is the integration of diverse data types and scales into cohesive models. For instance, the development of a spatial-temporal data framework to drive food web models with external data highlights the complexity of achieving model interoperability. This approach, part of the NF-UBC Nereus Program, aims to bridge the gap between ecosystem modeling tools and geographic information systems (GIS) technology, but it requires a flexible and modular software approach to separate technical and scientific challenges (Steenbeek et al., 2013). Additionally, the use of reaction-diffusion equations to model phytoplankton-zooplankton interactions demonstrates the difficulty in capturing the inherent patchiness and self-organized spatial patterns in marine environments (Chakraborty and Manthena, 2015). These challenges underscore the need for advanced modeling techniques and computational tools to accurately represent the dynamic nature of marine ecosystems. 8.2 Knowledge gaps and research needs Despite advancements in modeling and data collection, significant knowledge gaps remain in our understanding of marine ecosystem dynamics. One critical area is the impact of human activities and climate change on coral reef communities. Studies have shown that the degradation of coral reef habitats and changes in species composition may be linked to human-induced environmental modifications, but the extent and predictability of these changes are still uncertain (Pandolfi, 2002). Furthermore, the need for detailed information about habitat properties and their variation across spatial and temporal scales is crucial for effective ecosystem management. Modern 3D mapping technologies, such as drone-derived photogrammetry and terrestrial laser scanning, have begun to address this need by providing high-resolution data on biogenic reef structures, but more research is required to fully understand the implications of these findings (Jackson-Bué et al., 2021). 8.3 Emerging trends and innovations Emerging trends and innovations in the study of marine ecosystems are promising steps toward overcoming existing challenges and filling knowledge gaps. The integration of remote sensing data with food web models, as demonstrated in the NF-UBC Nereus Program, enhances the predictive capabilities of these models and provides a more accurate reflection of species population trends and distributions. Additionally, the application of modern 3D mapping technologies to characterize spatial and temporal dynamics in biogenic reef habitats offers new insights into ecosystem biodiversity (Figure 3), function, and resilience. These technologies have revealed previously undocumented patterns in reef accretion and erosion, highlighting the potential for advanced tools to enhance our understanding of ecosystem dynamics across scales (Gissi et al., 2019). Continued innovation in data collection, modeling, and analysis will be essential for addressing the complex and interconnected challenges facing marine ecosystems in the future. The figure illustrates the changes in species composition of different intertidal coral reefs and benthic communities over the course of a year. Capturing and analyzing these communities through 3D imaging technology provides an emerging research trend that allows scientists to observe and monitor biodiversity with unprecedented detail and precision. This innovative approach not only improves the efficiency and accuracy of data collection, but also provides valuable insights into the response of biological communities to environmental changes, thereby advancing the development of marine ecology research. 9 Concluding Remarks The research on the spatial and temporal dynamics of marine ecosystem structures in tropical oceans has revealed several critical insights. Firstly, the study of phytoplankton-zooplankton interactions using reaction-diffusion
