Abstract A high‐resolution, 3‐dimensional primitive equation model is used to investigate the cross‐shelf exchange in East China Sea (ECS). Favorable comparisons between field data and simulations from both climatological run hindcast for 2006 indicate that has essential skills capturing key physics of ECS. Temporal spatial variations exchanges are further analyzed. It was demonstrated observations high saline water could be delivered north Changjiang River mouth (near 32°N) as a result...
The global increase in coastal hypoxia over the past decades has resulted from a considerable rise anthropogenically-derived nutrient loading. spatial relationship between surface phytoplankton production and subsurface hypoxic zones is often explained by considering oceanographic conditions associated with basin size, shape, or bathymetry, but this not case where nutrient-enriched estuarine waters merge into complex circulation systems. We investigated physical biogeochemical processes that...
Two detachment processes of low salinity water (LSW) in the Changjiang Estuary July 2006, and role wind on detaching LSW particular, are explored with a three‐dimensional numerical model. The real‐case simulation sensitivity experiments results show that plays crucial events is highlighted three aspects. First, most important dynamic factor two LSW. Wind mixing, wind‐driven northward current wind‐induced upwelling driving forces LSW, which increase upper layer region along 30 m isobath...
Details of the development coastal hypoxia in response to passage Typhoon Bavi (2020) East China Sea were reconstructed by numerical modeling using a three-dimensional coupled physical–biogeochemical model. The model was validated via repeated surveys along transect across submerged river valley off Changjiang Estuary before and after Bavi. Before Bavi’s arrival, survey data indicated that had formed Estuary. However, not eliminated but instead migrated aggravated observed typhoon passage....
Abstract Time series data from a sediment trap at approximately 1,000‐m depth in the northwestern South China Sea, July 2012 to April 2013, were used combination with remote sensing and shipboard physical biogeochemical quantify effects of multiscale processes on sinking particle fluxes function local biological carbon pump. Total mass flux its primary components—particulate organic carbon, calcium carbonate, opal, lithogenic matter—exhibited similar temporal trends, three conspicuous...
Aluminum (Al) is one of the key parameters GEOTRACES. In spring 2011, we examined distribution dissolved Al in East China Sea (ECS) to assess potential passage coastal water across shelf western Pacific. Measurement coastal, shelf, and break waters indicated decreasing concentrations with distance from coast. However, northward increase upper 100 m along transect, corresponding flow Kuroshio Water Okinawa Trough north Taiwan Tokara strait, indicates contributions terrestrial material. The...
Abstract Hourly mapping by a Geostationary Ocean Color Imager was used to reveal the spatial pattern and tidal variation of total suspended solids (TSS) over Yangtze Bank in Yellow East China Seas during winter. The TSS form tongue-shaped structure, which decreases further offshore stepwise manner. change is separated two fronts TSS, are located near 20-m 50-m isobaths. concentration study period evident can be divided into three stages: decay, maintenance, growth. Compared with relatively...
Abstract Effects of aquaculture on hydrodynamics and associated nutrient supply in a typical area the coastal Yellow Sea are investigated with high‐resolution model experiments situ data. The results show significant reduction supply, which is alternations three hydrodynamic conditions: onshore current across outer‐boundary area, upwelling within offshore (depth >10 m) water exchange near‐coastal <10 area. First, bottom layer boundary, transports high‐concentration nutrients from major...
In spring 2013, 33 repeat shipboard Acoustic Doppler Current Profile (ADCP) surveys were conducted to measure the tidal current in Qiongzhou Strait (QS). The major currents and residual along a section across QS estimated using modified harmonic analysis method based on inverse technique. A simple simulation comparisons with previous observations demonstrated that are reasonable, this was able control magnitude deviation of estimation error. direction axis ellipses is generally strait....
Abstract. The seasonal mean and synoptic fluctuation of the wintertime Taiwan Warm Current (TWC) were investigated using a well-validated finite volume community ocean model. spatial distribution dynamics highlighted. TWC has two branches: an inshore branch between 30 100 m isobaths offshore 200 isobaths. Coriolis term is much larger than inertia almost balanced by pressure gradient in both branches, indicating geostrophic balance current. Two areas with significant fluctuations identified...
Abstract To better understand the geochemical cycle of dissolved manganese (Mn) in East China Sea (ECS), distribution Mn across ECS was investigated during three field studies 2011 (May, August, and November). The concentration decreased with distance from coast. Mn‐rich shelf waters could export to Kuroshio Waters, had potential influence northwest Pacific Ocean as well Japan Sea. Waters were devoid Mn, so its incursion be tracked it entered continental region (approximately 50 m isobath)....
Abstract Combining satellite altimetry and in situ hydrographic measurement, we estimated the cross‐shelf transport (CST) its spatial temporal variations across 200 m isobath East China Sea (ECS) from 1993 to 2014. The vertically integrated CST can be dynamically divided into three parts: surface Ekman transport, geostrophic bottom transport. results show that 22 year‐mean, sectionally 1.7 ± 2.0 Sv (positive on‐shelf direction), comprised of transports 2.7 1.0 0.6 Sv, respectively, are...
Abstract Eddy-induced heat transport (EHT) in the South China Sea (SCS) is important for budget. However, knowledge of its variability limited owing to discrepancies arising from limitation down-gradient method and uncertainties numerical models. Herein, we investigated spatiotemporal dynamics EHT using a well-validated assimilated model. In particular, southeast Vietnam (SEV) west Luzon Strait (WLS), significant values annual mean are observed most confined upper 400 m. also exhibits...
Abstract Remote sensing observations reveal strong differences in winter cross-shore movements of the outer salinity fronts between midfield and far-field regions outside China’s Changjiang River plume. However, characteristics, mechanisms, associated water exchanges these remain unclear. Based on 7-yr buoy a high-resolution model, we investigate periods synoptic (∼9–13 days) variation spring–neap tidal cycle for far field. Their manifest as oscillations an alternation single double In...
Abstract The filamentous Trichodesmium and Richelia / Calothrix appear to be crucial N 2 ‐fixing cyanobacteria throughout the warm oligotrophic ocean, particularly in western boundary currents. Kuroshio, hotspot of fixation Pacific Ocean, intrudes into East China Sea (ECS) southern Yellow (SYS), which may profoundly influence composition distribution diazotrophs. We provide high spatial resolution dataset diazotrophs ECS SYS July August 2013. Results showed that colonies Richelia/Calothrix...
Abstract Based on velocity and nutrient data from satellite in situ measurements, we studied the temporal spatial variations for 22‐year (1993–2014) cross‐shelf exchange at 200‐m isobath section East China Sea. Since nitrate phosphate concentrations were highly correlated (correlation coefficient of 0.95), only transport was investigated detail. The is explored whole to results show that averaged section‐integrated ( FQ ) 22.0 ± 12.4 kmol/s (+ on‐shelf direction). Its interannual variation...
Abstract Biological carbon pump (BCP) inefficiency was first observed in the South China Sea (SCS) throughout 1997–1999 El Niño Southern Oscillation (ENSO) event, but BCP usually recovers its efficiency when climate conditions change from to La Niña Pacific Ocean. Enhanced stratification and Kuroshio intrusion led weak mixing oligotrophic sunlit layer of SCS during 1997/1998 phase, particulate organic (POC) flux comparable climatological mean due ballast effect increased lithogenic material...
