Therefore, continuous tracking and management of marine animals, as well as understanding their behavior patterns, have to study for effectively managing the marine ecosystem. This paper aims to design and implement a responsive system that can manage and support marine ecosystems by analyzing the home range and visualizing data of marine animals, including their location information. To achieve this objective, we developed an algorithm that utilizes open-source R-based methods such as minimum convex hull polygon and kernel density to estimate home range. Additionally, a Shiny-based reactivity web application was implemented to visualize the results on a map. As a result, researchers in the field of marine animals and marine ecology were able to analyze behavior patterns using attribute conditions such as the type and location information transmission time of marine animals without a separate GIS analysis program. In addition, the analysis results were visually presented on a map to enable a clear and intuitive comprehension of the movements of marine animals. If the system is continuously developed through research in the future, we expect to efficiently manage the marine ecosystem and provide even more insightful information. [ABSTRACT FROM AUTHOR]

Choi, H.-J.; Cho, S.-J.; Kim, T.H., and Nam, J., 2023. Assessment of Marine Use Zones (MUZs) in the spatial planning of Jeonbuk sea waters (southwestern Korean peninsula). In: Lee, J.L.; Lee, H.; Min, B.I.; Chang, J.-I.; Cho, G.T.; Yoon, J.-S., and Lee, J. (eds.), Multidisciplinary Approaches to Coastal and Marine Management. Journal of Coastal Research, Special Issue No. 116, pp. 338-342. Charlotte (North Carolina), ISSN 0749-0208. The Korean government has adopted marine spatial planning as a new policy tool for integrated marine space management and has designated nine Marine Use Zones (MUZs) on all sea water areas. To designate MUZs, it is necessary to conduct a Marine Spatial Assessment (MSA) to identify the scope and level of core activities and spatial conflict potential between MUZs. This paper covers the MSA method for Jeonbuk waters and discusses the limitations and implications of the current MSA for the effective designation of the MUZs. Marine spatial planning (MSP) for Jeonbuk considers various demands for use and development, such as leisure, marine energy development, and the Saemangeum construction project, as well as the protection of excellent ecology and scenery, such as tidal flats and islands. Thus, MSA was conducted to designate MUZs that reflect these regional characteristics well according to relevant guidelines. The MSA procedure consists of preparation, data collection and processing, characteristic evaluation, and conflict analysis. Specifically, data on marine use and those pertaining to resources of the target sea were collected and transformed into grid-based (3'x3') GIS data. Based on these results, the MUZs in the target area were designated and managed. This study had several limitations and implications. First, there were difficulties in defining core activities according to the accessibility and availability of input data for MSA. Hence, methods and techniques such as data fusion and their spatial interpolation are required to overcome these limitations. Second, a future study (e.g., ecosystem services) should be conducted to quantitatively evaluate and visualize the value of benefits provided by marine ecosystems. Third, location-based AIS and fishing boat data are likely to prove useful for identifying the characteristics of dynamic activities such as fishing and shipping. Finally, it is necessary to apply simulation model to reflect not only the recent behavior pertaining to the use of marine space and resources, but also potential future behavior relating to MUZs.
