An attention U-Net was proposed to reconstruct the missing chlorophyll-a concentration (Cchla) data. The is a lightweight full convolution neural network architecture consisting of an enccoder-decoder (i.e., down-sampling and up-sampling). gates (AGs) were integrated into U-Net. Training with AGs could implicitly teach it suppress irrelevant areas highlight salient features in data areas, which would increase sensitivity reconstruction accuracy. uses satellite-derived Cchla anomalies its...
Abstract This study evaluated the effect of probiotics ( Clostridium butyricum , Bacillus coagulans ) and Chinese herb polysaccharides (Astragalus polysaccharides, APS) on growth performance, immunity, disease resistance, intestinal microbiota rainbow trout Oncorhynchus mykiss ). Specimens O. n = 360; 79.9 ± 2.2 g) were fed for 42 days with different diets containing a basal diet (control, C0), supplemented 10 9 CFU/kg C. + B. (E1) 100 g/kg APS (E2) as experimental diets. The results...
The abundance of phytoplankton is generally estimated by measuring the chlorophyll-a concentration (Cchla), which an important factor in photosynthesis and can be used to analyze density biomass ecosystem. band-ratio-based empirical or semi-analytical algorithms are operationally applied retrieve Cchla global oceans, experience difficulties from diversity optical properties complexity radiative transfer equations analytical analyses, respectively. With attempt develop accurate retrieval...
Several methods have been proposed for atmospheric correction over turbid waters, including near-infrared (NIR) band based or short-wave infrared (SWIR) band-based where the signal in waters can be assumed zero. Here, we adopt a new extrapolation method to extend existing water of operational land imager (OLI) data on Landsat-8 platform. The uses extrapolated Rayleigh-corrected reflectance at NIR and SWIR bands derive ratios visible aerosol single-scattering contributions (aerosol epsilon)....
A MODIS-based algorithm was developed to investigate the impact of Typhoon Vicente on total suspended solid concentration in Pearl River Estuary. This used two high resolution bands at 645 nm and 555 map concentrations. Regression between remote sensing reflectance situ showed good correlation (R2 = 0.91), indicating that valid for turbid waters MODIS-derived maps different anomalies sub-regions estuary during passage Vicente. In western inlets, increase solids (maximum values 22.20 g m−3...
Phytoplankton dynamics, which are highly sensitive to the ecosystem condition and change, different in coastal waters open ocean. Previous researches mainly focused on ocean dynamic South China Sea (SCS), but few research Eastern Guangdong (EGD), especially during a period of downwelling-favorable winds. In fact, influence topographic irregularities, downwelling, continental outflows, cold, nutrient-rich currents from Fujian-Zhejiang (ZFC) East (ECS) spatial distribution Chlorophyll (Chl a)...
An empirical algorithm is proposed to estimate suspended particulate matter (SPM) ranging from 0.675 25.7 mg L-1 in the turbid Pearl River estuary (PRE). Comparisons between model predicted and situ measured SPM resulted R2s of 0.97 0.88 mean absolute percentage errors (MAPEs) 23.96% 29.69% by using calibration validation data sets, respectively. The developed demonstrated highest accuracy when compared with existing ones for coastal waters. diurnal dynamics was revealed applying reflectance...
Vibrio ponticus is a vital pathogen with potential danger for aquaculture animals. Yet V. pathogenic to the coral trout Plectropomus leopardus still unknown. In this study, virulent bacterial strain, temporarily named DX2, was isolated from diseased suffering liver necrosis cell vacuolar degeneration, and identified molecularly phenotypically as . Besides, DX2 isolate showed an LD 50 value of 6.64×10 5 CFU mL -1 , developed multiple resistances cephalosporins, macrolides, penicillins,...
The development of microbial communities is important for the growth fat greenling Hexagrammos otakii; however, relationship between and fish diet poorly understood. Here, we used metagenomics sequencing to investigate gut microbiota H. otakii at three key time points during development. diversity community composition presented stage-specific signatures appeared shift with different diets environmental conditions such as NH4 + -NO2- etc. Metagenomics analysis indicated that dominant phyla...
We evaluated six empirical and semianalytical models of the diffuse attenuation coefficient at 490 nm (Kd(490)) using an in situ dataset collected Pearl River estuary (PRE). A combined model with most accurate performance (correlation coefficient, R2 = 0.92) was selected applied for long-term estimation from 2003 to 2017. Physical biological processes PRE over 14-year period were investigated by applying satellite observations (MODIS/Aqua data) season-reliant orthogonal function analysis...
A 4-week feeding trial was conducted to determine the effects of different dietary supplements on growth, immunity and resistance sea cucumber Apostichopus japonicus against Vibrio splendidus infection. The control group supplied with blank microcapsules, Astragalus polysaccharide (APS) tuckahoe (TPS) (APS + TPS) microcapsules Bacillus subtilis, were tested for effects. Coelomic fluid collected at 7-day intervals test activities lysozyme (LSZ), superoxide dismutase (SOD), alkaline...
The Sustainable Development Goal Satellite 1 (SDGSAT-1) is the world's first science satellite dedicated to serving United Nations 2030 Agenda for Development. Multispectral Imager Inshore (MII) onboard SDGSAT-1 provide an alternative data source effectively monitor coastal water environments. In this study, performances of MII in red tide detection were evaluated along Guangdong middle coast. First, radiometric estimated. in-orbit signal-to-noise ratios (SNRs) blue and green bands range...
Abstract. Satellite remote sensing of sea surface chlorophyll products sometimes yields a significant amount sporadic missing data due to various variables, such as weather conditions and operational failures satellite sensors. The limited nature observation impedes the utilization in domain marine research. Hence, it is highly important investigate techniques for reconstructing obtain spatially temporally uninterrupted comprehensive within desired area. This approach will expand potential...
