Abstract River freshwater fluxes are fundamental inputs for regional and global ocean models. Nonetheless, most models currently forced by climatological runoff data, encompassing several limitations resulting in significant biases the simulated conditions. This study evaluates daily river discharge into South East Asia (SEA), a region having one of greatest runoffs world. The data provided at 1/10° resolution Global Flood Awareness System (GloFAS) reanalysis through comparison with observed records climatology. advantages using such high product numerical simulation assessed looking its impact on variability distribution sea surface salinity (SSS), mesoscale processes particles’ Lagrangian dispersion within Indonesian seas. Our results show satisfying performance GloFAS major rivers China Sea, while no systematic errors were identified remaining areas interest. Finally, realistic modeling whole SEA region, we underline importance accurate discharges order to properly reproduce local dynamics, which play key role shaping SSS patterns affect stranding marine debris.

The recurring occurrence of green tides as an ecological disaster has been reported annually in the Yellow Sea. While remote sensing technology effectively tracks scale, extent, and duration tide outbreaks, there is limited research on underlying driving mechanisms drift transport determination leeway coefficient. This study investigates mechanism evaluates feasibility estimating coefficient by analyzing velocities obtained from Geostationary Ocean Color Imager-II (GOCI-II) images using maximum cross-correlation (MCC) technique method across various time intervals alongside ocean current wind speed data. results reveal following: (1) Significant spatial variations movement, with a distinct boundary at 34°40′N. (2) Short-term primarily influenced tidal forces, while currents, especially combined Ekman geostrophic component, predominantly govern net transport. (3) Compared to 1, 3, 7 h intervals, 25 interval feasible for moderate-resolution geostationary images, yielding values consistent previous studies. offers new insights into exploring through sensing-driven velocity.

Marine litter in coastal areas can bring economic, social, and environmental damage, especially the loss of aesthetic value a tourist site. Therefore, research on composition marine to identify its sources is important for planning strategic action minimize problem. This study analyzed beach five beaches (Kondangmerak, Balekambang, Ungapan, Ngudel, Goa Cina) along Indian Ocean coastline eastern part south Java region, Indonesia. All are known as famous touristic Malang City, receive many visitors, during holiday season. Beach was obtained by collecting different types 5 x m square transect. Five transects were placed strandline at each beach, intervals 20 separated In transect, collected counted based category (plastic, paper, rubber, fabric, processed wood, metal, glass, ceramic, hazardous items) size (0.5–2.5cm, 2.5–5cm, 5–10 cm, > 10 cm). There statistically significant variation number litters among sizes (p<0.05). However, distribution remained consistent across regardless size. general, with cm found least all (< 15%), while other three categories similar numbers (in range 20% 50%).
