Abstract Using satellite‐derived and in situ data, the wind‐driven potential new production (nitrate supply) for 300 km wide coastal band two upwelling regions of western Arabian Sea (AS) during southwest monsoon is estimated. The upward nitrate flux to euphotic zone generally based on physical processes transport (Ekman geostrophic transport) offshore Ekman pumping. current AS influences intensity latitudinal distributions supply. Oman Somalia have similar level summer monsoon, while...
Hyperspectral images (HSI) find extensive application across numerous domains of study. Spectral superresolution (SSR) refers to reconstructing HSIs from readily available RGB using the mapping relationships between and HSIs. In recent years, convolutional neural networks (CNNs) have become widely adopted in SSR research, primarily because their exceptional ability extract features. However, most current CNN-based algorithms are weak terms extracting spectral features While certain can...
Abstract The temperature, salinity, and chlorophyll‐ a (Chl‐ ) profiles of the upper ocean (0–200 m) were measured during China‐Pakistan Joint Expedition, 2017. cruise track passed through an identified cyclonic eddy, multi‐disciplinary records thus verify eddy contributions to winter blooms in northern Arabian Sea (AS). show that strength within mixed layer is mainly dominated by surface phytoplankton biomass (the Chl‐ concentration), which increases simultaneously with shallow uplifted...
Abstract This study investigated boreal wintertime phytoplankton blooms in the western equatorial Indian Ocean (WEIO) and underlying physical mechanisms. The Sea viewing Wide field of View sensor (SeaWiFS) chlorophyll‐ a (Chl ) concentrations show that occur WEIO during December–March. development these is not only seasonal process but also consists 2–3 intraseasonal events induced by Madden‐Julian Oscillation (MJO). During typical event, enhanced cross‐equatorial wind induces strong...
Chlorophyll-a (Chla) concentration derived from the Sea viewing Wide field of View sensor (SeaWiFS) data (January 1998 to December 2010) shows phytoplankton blooms in western south equatorial Indian Ocean (WSEIO) during summer monsoon. The mechanism that sustains is investigated with high-resolution General Circulation Model for Earth Simulator (OFES) products. WSEIO are separated coast; they occur June, reach their maximum August, and decay October. With monsoon onset, cross-equatorial wind...
River plumes play an important role in the cross-margin transport of phytoplankton and nutrients, which have profound impacts on coastal ecosystems. Using recently available Soil Moisture Active Passive (SMAP) sea surface salinity (SSS) data high-resolution ocean color products, this study investigated summertime high-frequency variations Pearl plume China its biological response. The SMAP SSS captures intraseasonal oscillations offshore well, has distinct 30–60 day from mid-May to late...
More than ten years of satellite-derived net primary production (NPP) data were used to investigate the interannual variations NPP associated with two different types El Niño in South China Sea (SCS). Results empirical orthogonal function analysis (EOF) showed that first modes had significant and sensitive Niño. The mode is highly correlated canonical This characterized by basin-scale decreased during years, predominantly diminished off east coast Vietnam northwest Luzon. second well Modoki,...
Abstract This study investigates extreme phytoplankton blooms in the southern tropical Indian Ocean (TIO) January–April 2011 using extended ocean color products and situ data. The amplitude of was approximately 4 times higher than climatological value 2 that 1998–1999. anomalous enhancement surface chlorophyll‐ a concentration (Chl ) associated with strong upwelling Rossby waves forced by extraordinary wind stress curl southeastern TIO during 2010–2011 La Niña, which much stronger 1998–1999...
The suspended particle size has great impacts on marine biology environments and biogeochemical processes, such as the settling rates of particles sunlight transmission in water. However, spatial–temporal variations sizes coastal waters are rarely reported due to paucity appropriate observations limitations retrieval methods, especially areas with complex optical properties. This study proposed a remote sensing-based method for estimating median Dv50 (calculated range 2.05–297 μm) that...
The Drake Passage is known for its abundant mesoscale eddies, but little about their three-dimensional characteristics, which hinders our understanding of impact on eddy-induced transport and deep-sea circulation. A 10-year study was conducted using GLORYS12 Mercator Ocean reanalysis data from 2009 to 2018. analyzed the statistical characteristics eddies in Passage, spanning surface down a depth 2000 m three dimensions. findings indicate that mean radius 35.5 km, with lifespan 12.3 weeks...
To estimate the changes in annual mean sea level (MSL) and extreme levels (ESLs), largest collection of tide gauge records from 10 tidal stations along northern coast South China Sea (SCS) were analyzed this study. Here, all had been homogenized by a two-step process involving detection inhomogeneities, that is, breakpoints caused non-climatic application adjustment. The study’s conclusions, based on records, can be summarized as follows: instrument change station relocation are main causes...
The phytoplankton size structure exerts a significant influence on ecological processes and biogeochemical cycles. In this study, the interannual variations in remotely sensed southern Tropical Indian Ocean (TIO) underlying physical mechanisms were investigated. Significant fluctuations occur southeastern TIO central are very sensitive to Dipole (IOD) events. During positive IOD events, southeast wind anomalies reinforce coastal upwelling off of Java Sumatra, leading shift toward larger TIO....
Cross-slope eddies play an important role in the exchange of water, salt, heat, nutrients, chlorophyll, phytoplankton and other biogeochemical elements between basin shelf South China Sea. The cross-slope transport process by a mesoscale anticyclonic eddy is studied ROMS model satellite data. 1000 m isobath was considered as proxy for slope. anticyclone shows different features at places on slope: (a) volume northeast slope off-slope, while southwest on-slope; (b) both off-slope transports...
The international array for real-time geostrophic oceanography (Argo) project is committed to rapidly and precisely acquiring comprehensive 3-D data on ocean temperature salinity, which crucial monitoring climate change natural phenomena. During the buoy observation, environmental factors, human mistakes, equipment malfunctions can cause abnormalities such as density inversion spike, thus detecting errors in Argo significant ensure its reliability applicability. Traditional methods mainly...
