Abstract With the rapid economic development, increase of human activities in coastal areas, continuous discharge pollutants from land-based sources into sea, and protection offshore by sea-related management departments, judgment early warning level marine ecosystems is therefore great significance. The article based on survey monitoring data Ocean A 2022-2023 utilizes MNDWI Otsu to extract multimodal remote sensing data. Then, environmental status ocean analyzed. By constructing indicator system ecosystem P-R-S model exploring integrated analysis method BP ANN ecosystem, condition was warned, results were show that 2020 2023, degree sustainable development will be state “light warning”-a strong development.

Harmful algal blooms (HABs) present severe risks to marine ecosystems, wildlife, human health and economies globally. This study investigates the diversity abundance of primary HAB group-dinoflagellates-in Hervey Bay, Queensland, Australia, a region notable for its ecological uniqueness high susceptibility HABs. By employing DNA metabarcoding targeting 18S rRNA V8-V9 regions, we aimed provide comprehensive overview dinoflagellate communities across various substrates locations, identifying both toxic non-toxic species. Our findings revealed 66 distinct genera, including known toxin producers such as Alexandrium, Gambierdiscus, Karenia Prorocentrum, with some species detected in Australian waters first time. Additionally, assessed these examined influence environmental factors on their occurrence. emphasises importance ongoing monitoring assessments manage impacts vulnerable coastal areas Bay.

ABSTRACT This study assessed the impacts of anthropogenic and climate change on harmful algal blooms (HABs) in Dongzhang Shanzai Reservoirs from 1990 to 2023, focusing land use cover (LULCC) analysis. Through supervised classification Landsat imagery, examined changes cropland, forest, shrub, grassland water, barren built‐up areas watersheds both reservoirs monitor HABs events. The catchment saw forest increase 72.0% 75.3% 2010 before decreasing 71.7% 2022, while cropland fluctuated. Similarly, Shanzai's declined 94.4% 1996 91.4% with increasing. Significant HAB events Reservoir peaked 1990, affecting up 40% reservoir's area 2022. In Reservoir, showed an increasing trend 2018, a peak 2018 when was affected. Land exacerbate HABs, as seen declining areas. Analysis using imagery occurrences rising water temperatures indicating potential future increases. Addressing activities are vital prevent manage requiring improved monitoring early warning systems. With remote sensing, quality issues can be identified managed. findings emphasize need for continuous monitoring, LULCC analysis, sediment pollution research effective management strategies protect ecosystem health under change. Recommendations include long‐term nutrient input investigations, modelling studies, systems adaptation strategies.
