The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked orbit perturbations.Tide under review include empirical, purely hydrodynamic ("forward"), assimilative dynamical, i.e., constrained by observations.Ten dominant tidal constituents in the diurnal, semidiurnal, quarter-diurnal bands are considered.Since last major model comparison...
A new global ocean tide model named DTU10 (developed at Technical University of Denmark) representing all major diurnal and semidiurnal tidal constituents is proposed based on an empirical correction to the FES2004 (Finite Element Solutions), with residual tides determined using response method. The improvements are achieved by introducing 4 years TOPEX–Jason 1 interleaved mission into existing 18 (1993–2010) primary joint TOPEX, Jason 1, 2 time series. Hereby spatial distribution...
The Shell North Sea Gannet Alpha platform oil spill accident occurred on August 10, 2011. This was the largest in United Kingdom waters last decade. spills were observed four COSMO-SkyMed (CSK) X-band synthetic aperture radar (SAR) images acquired between 17 and 22, 2011, with revisit time from 11 h to 3 days SAR acquisitions. areas of slicks extracted using an existing image classification segmentation algorithm. It found that moved toward southwest slick size enlarging 3.69 62.01 km2 first...
A massive green tide (i.e., Ulva prolifera bloom) event in summer 2015 the Yellow Sea was investigated using satellite imagery and a trajectory model. First, occurrence evolution of macroalgal bloom were studied based on time series cloud-free Moderate Resolution Imaging Spectroradiometer during May to August Floating Algae Index detection method. Lagrangian spill model, i.e., General NOAA (National Oceanic Atmospheric Administration) Operational Modeling Environment (GNOME) which originally...
In this study, an Attention U-net network was proposed to reconstruct the subsurface temperature (ST) field with high temporal and spatial resolution in South China Sea (SCS) from sea surface parameters observed by satellites. addition temperature, level anomaly wind field, stress curl, which influences three-dimensional structure of through induced Ekman pumping transport, also input into model. The 5-day average vertical profiles 0.5° Simple Ocean Data Assimilation (SODA) reanalysis...
For ocean and climate research, it is essential to get long-term altimetric sea level data that as accurate possible. However, the accuracy of frequently degraded in interior Arctic Ocean due presence seasonal or permanent ice. We have reprocessed ERS-1/2/Envisat satellite altimetry develop an improved 20-year dataset for Ocean. developed both along-track three-day gridded anomaly (SLA) maps from September 1992 April 2012. A major improvement coverage was gained by tailoring standard editing...
We evaluated the association of cardiorespiratory fitness and physical activity to mortality in 7,855 women 25,218 men examined during 1970–1994. All participants were apparently healthy completed a maximal exercise test on treadmill. Participants followed date death or 12/31/94 for survivors. There 102 deaths 743 men. assigned 3 categories (Sedentary, Active = up 19.9 MET hours/week, Highly active ≥ 20 hours/week), (Low least fit 20%, Moderate next 40%, High most 40%). was significant...
High-resolution salinity information is of great significance for understanding the marine environment. We here propose a deep learning model denoted “Attention U-net network” to reconstruct daily fields on 1/4° grid in interior South China Sea (SCS) from satellite observations surface variables including sea salinity, temperature, level anomaly, and wind field. The vertical profiles GLORYS2V4 reanalysis product provided by Copernicus Marine Environment Monitoring Service were used training...
Detailed information about mangroves is crucial for ecological and environmental protection sustainable development. It difficult to capture small patches of from satellite images with relatively low medium resolution. In this study, high-resolution (0.8–2 m) Chinese GaoFen (GF) ZiYuan (ZY) series satellites were used map the distribution in coastal areas Guangdong Province, China. A deep-learning network, U2-Net, attention gates was applied extract multi-scale images. The results showed...
The incomplete eye structure during the generation and weakening stages of tropical cyclones (TCs) makes it difficult to accurately locate low-intensity TCs in satellite infrared (IR) images. Here, we develop a physics-enhanced deep convolutional neural network (CNN) determine centers depressions (TDs) storms (TSs) with maximum sustained wind speed (MSW) below 63 kt. This is accomplished by integrating consecutive IR images from Himawari-8 geostationary historical information including...
While global mean sea level rise (SLR) and acceleration (SLA) are indicators of climate change informative regarding the current state climate, assessments regional local SLR essential for policy makers responding to, preparing for, changes in level. In this work, three detection techniques used to demonstrate robust SLA China Seas. Interannual multidecadal variations (periods >2 years), which mainly related natural internal variability significantly affect estimation acceleration,...
In this paper, the capability of advanced scatterometer (ASCAT) in measuring surface wind speed coastal waters China was first evaluated by comparing with <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">in situ</i> observations from 13 moored buoys during period July 2013 to December 2015. The performs well most regions China. However, a sharp reduction retrieval accuracy is found areas adjacent Yangtze River estuary. mean bias and...
The exploration of sea level variability from multiple satellite altimetry measurements in the Baltic Sea is yet to be performed due lack reliable data, especially near coast. In present study, number available altimeter was increased by 96% coastal regions replacing radiometer wet troposphere correction with model-based correction. data show good agreement monthly tide gauge mean a root square difference (RMSD) 3.4 cm and correlation coefficient 0.97 at 42 gauges Sea, higher RMSD lower Gulf...
