Abstract Coastal eutrophication and hypoxia remain a persistent environmental crisis despite the great efforts to reduce nutrient loading mitigate associated damages. Symptoms of this have appeared spread rapidly, reaching developing countries in Asia with emergences Southern America Africa. The pace changes underlying drivers not so clear. To address gap, we review up-to-date status mechanisms global coastal oceans, upon which examine trajectories over 40 years or longer six model systems...

This paper assesses impacts climate change, terms changed basin water balance sea level rise, on pulse. were simulated by three-dimensional hydrodynamic model using projected changes mainstream discharge under influence change as boundary conditions. simulations that average maximum levels duration increase...
Japan recently announced plans to discharge over 1.2 million tons of radioactive water from the Fukushima Daiichi Nuclear Power Plant (FDNPP) into Pacific Ocean. The contaminated can poses a threat marine ecosystems and human health. To estimate impact plan, here, we developed three-dimensional global model track transport dispersion tritium released FDNPP. pollution scenarios for four release durations (1 month, 1 year, 5 years, 10 years) were simulated. simulation results showed that in...
Abstract Internal solitary waves (ISWs) typically exhibit a strong tendency to preserve their waveforms and amplitudes upon collision, but this preservation breaks down when two ISWs obliquely interact. Although oblique wave‐wave interactions have been frequently observed in the oceans worldwide studied extensively through theoretical research satellite imagery, fundamental underwater dynamics spatiotemporal evolution of these remain poorly understood. This study presents detailed...
The 2021 eruption of Fukutoku-Oka-no-Ba (FOB) in the northwest Pacific on 13 August produced a large volume pumice that drifted westward for ~1300 km to Nansei Islands, Japan, and some extent. In February 2022, with similar characteristics FOB was deposited along Gulf Thailand. clasts Songkhla Province, Thailand, were fine-grained <4 cm size rounded. Most consisted clinopyroxene, plagioclase (andesine), olivine phenocrysts vesiculated grey groundmass, black-coloured spots exhibiting...
A numerical model was applied to simulate the transport of 137Cs released with waters which were used cool Fukushima reactors. These stored will be Pacific Ocean according Japanese government plans. The radionuclide is Lagrangian and includes interactions sediments an integrated dynamic foodweb for biota uptake. Calculations made from a conservative approach indicate that expected concentrations in marine fish would orders magnitude below those detected after accident also lower than...
Abstract The Indian Ocean Dipole (IOD) has been extensively studied for its significant impact on salinity distribution in tropical regions. However, off‐equatorial influence the northeastern (IO) received limited documentation thus far. In October 2019, a buoy central Andaman Sea (AS) observed an extreme freshening event that resulted intensified upper‐ocean stratification and increased internal wave activities. salt budget evaluation revealed dominant role of horizontal advection....
The application of internal wave recognition to the buoy system is great significance enhance understanding ocean phenomenon and provide more accurate data information support. This article proposes an automatic algorithm based on convolutional neural networks (CNN), which used in tight-profile intelligent system. sea profile temperature were collected using Bailong Andaman Sea 2018. CNN network structure applied feature compression data, reducing input amount network, thereby overall...
The internal wave recognition algorithm in an ocean data buoy system can be used to realize the real-time and flexible observation of waves, but there is no accurate automatic method. To meet need for automatic, real-time, reliable recognition, has been proposed a tightly profiled intelligent system. sea profile temperature collected by Bailong Andaman Sea 2018 were train test neural network model, which consists two parts: feature extraction classification. experiment compares long...

Abstract Beginning with the TOPEX/Poseidon altimetry mission in 1992, along-track satellite sea surface height (SSH) estimates have been taken every 6–7 km at 10-day intervals a cluster of tracks across Bering Strait near 66°N where turn. Year-to-year geostrophic SSH flow show that warmer months is almost entirely confined to 50-m-depth channel rather than whole cross-sectional area and peak-to-peak transport change comparable approximate 0.8 Sverdrup mean (Sv; 1 Sv ≡ 10 6 m 3 s −1 ).
