Summary: Petroleum extraction, transportation, and consumption in the marine environment contribute to a large portion of anthropogenic oil spills into the ocean. This study used optical imagery to detect oil slicks in the northern South China Sea and identified their sources. The results demonstrate the capability of medium-resolution optical imagery in monitoring regional oil spills.

Summary: This paper focuses on the dispersion processes of Cs-137 in the BYECS region, characterized by high turbidity and multi-scale circulations. By developing a radionuclide dispersion model and using a multi-fraction sediment transport model, the study reveals the significant influence of erosion processes on the distribution of Cs-137 in shallow areas.

Summary: Submesoscale processes in the ocean were investigated using numerical simulations in the East China Sea. It was found that the western boundary jet served as an important energy reservoir, and submesoscale footprints were observed in the continental slope and lee area of the Tokara Strait.

Summary: Using remote sensing images and numerical experiments, this study identifies two possible origins of floating S. horneri in the East China Sea and reveals their movement in space and time. The findings are important for implementing mitigation strategies and understanding possible ecological impacts along the drifting pathways of this seaweed.

Summary: This study investigated a nine-year time series data from 2010-2018 near the East China Sea, showing significantly greater trends of surface seawater pCO2 and pH compared to other oceanic time series. Mechanistic analysis revealed that seawater warming caused rapid increases in pCO2 and acidification, leading to a decline in CO2 uptake through air-sea exchange. The results suggest that rapidly warming boundary currents could result in an elevated pCO2 trend and a gradual reduction in oceanic CO2 uptake.

Summary: Predicting the risk of harmful algal blooms (HABs) in the East China Sea is important for mitigating the damage caused. By using historical data and satellite-derived sea surface temperatures (SSTs), a simple method based on SST or SST change rate was proposed to assess HAB risk. The method can predict the risk 1-2 months in advance, aiding in the reduction of damage.

Summary: This study used satellite-observed data and LSTM neural network to predict the concentration of chlorophyll-a in the East China Sea. The results showed that the predictions effectively simulated the seasonal distribution of chlorophyll-a concentration, but underestimated the extreme concentrations in the high-concentration region. Sensitivity experiments indicated that the prediction accuracy decreased when the backward prediction time step increased. The study's limitation was that it only considered the impact of chlorophyll-a on the prediction, without considering other relevant marine elements.

Summary: The water mass in the East China Sea shelf has a complex 3D hydrologic structure. This study used 3D interpolation technology to reconstruct the hydrologic structure based on in situ observations, and found that the cubic and thin plate spline RBFs were accurate methods. The reconstruction showed a reasonable 3D hydrologic structure and provided detailed information on the water masses, while also evaluating satellite-derived sea surface temperature.

Summary: Continental shelves and estuaries are important regions for the production and emission of N2O, with variations in distribution and emissions affected by temperature gradients, currents, and riverine inputs. N2O concentrations peak in spring and decrease sharply in summer and fall, with higher emissions in the ECS compared to the SYS. Sediments, especially around the Yangtze River Estuary, are identified as significant benthic N2O sources.

Summary: Sea surface temperature (SST) is an important factor in the ocean-atmosphere interaction, and accurate prediction of its distribution is crucial for climate change, disaster prevention, and marine ecological protection. This study uses LSTM neural networks to establish a prediction model for the next five days in the East China Sea, and investigates the impact of different parameters on prediction accuracy. The results show that the input data length of the LSTM model can enhance its prediction performance to a certain extent, but increasing the length does not necessarily improve accuracy. Additionally, the model accurately predicts the SST in the selected points, especially in the Pacific Ocean.

Summary: The interannual sea surface temperature trend in the East China Sea (ECS-Kuroshio) differs significantly from that of the ECS-shelf region. Observational temperature data from 1982 to 2014 indicate that the upstream ECS-Kuroshio shows an opposite temperature trend to the downstream, creating a horizontal dipole structure. The variability in upwelling in the upstream ECS-Kuroshio is the main factor influencing this distinct temperature trend, which can be transported downstream through horizontal advections.

Summary: This study confirmed the existence of cross-shelf transport off northern Taiwan through remote sensing data and heat flux data, which can be categorized into cold eddy and cold water tongue patterns. Topographic changes and the presence of a thermal front are important factors in inducing cross-shelf transport. Strong winds and typhoons can also enhance cross-shelf transport.

Summary: A study investigated the long-term impact of the Fukushima nuclear power plant accident on the South China Sea and the East China Sea. It was found that radioactive cesium isotopes from the accident intruded into these areas in 2013 and reached a peak in 2014. This intrusion was caused by the formation, subduction, and transport of subtropical and central mode water, which carried the radioactive cesium from the high-latitude open ocean to the low-latitude western boundary area, and then entered the South China Sea and the East China Sea through the Kuroshio Current.

Summary: Using a physical-biological coupled model, researchers quantified the nitrogen budgets of riverine dissolved inorganic nitrogen (DIN) and particulate organic nitrogen (PON) in the East China Sea (ECS). The Changjiang River plays a dominant role in nitrogen input, with the horizontal distributions of Changjiang DIN and PON being influenced by coastal currents and vertical stratification. Overall, less than half of DIN is converted to PON, with most leaving the ECS through lateral transport pathways, especially through the Tsushima Strait.
