From September 2009 to August 2010, intensive monthly sampling of nutrients was conducted at two stations the mouth Changjiang (Yangtze River). Particulate organic carbon (POC), particulate nitrogen (PN), and their stable isotope values ( δ 13 C 15 N) were also measured in selected samples all months. Most (nitrate, phosphate, ammonia, nitrite) as well POC, PN, displayed peak when highest or lowest discharges occurred, suggesting strongly influence seasonal variations these chemicals. The...
Mesoscale eddies, which contribute to long-distance water mass transport and biogeochemical budget in the upper ocean, have recently been taken into assessment of deep-sea hydrodynamic variability. However, how such eddies influence sediment movement deepwater environment has not explored. Here for first time we observed processes driven by mesoscale northern South China Sea via a full-water column mooring system located at 2100 m depth. Two southwestward propagating, deep-reaching...
This study aimed to address the problems of low detection accuracy and inaccurate positioning small-object in remote sensing images. An improved architecture based on Swin Transformer YOLOv5 is proposed. First, Complete-IOU (CIOU) was introduced improve K-means clustering algorithm, then an anchor appropriate size for dataset generated. Second, a modified CSPDarknet53 structure combined with proposed retain sufficient global context information extract more differentiated features through...
Abstract A total of 13 cruises were performed in different seasons between July 2010 and 2012, various subsystems the Changjiang (Yangtze River) Estuary adjacent East China Sea (ECS). Multiple vessels deployed to conduct transect sampling, simultaneous consecutive sampling with buoys, during phytoplankton bloom events, which allowed us track detached patches water masses collect discrete time‐series samples patches. We found that river‐derived nutrients from could be transported through...
Abstract A procedure for estimating thermal variance dissipation rate χT by scaling the inertial-convective subrange of temperature gradient spectra from thermistor measurements on a Tropical Atmosphere Ocean (TAO) equatorial mooring, maintained NOAA’s National Data Buoy Center, is demonstrated. The wavenumbers/frequencies contaminated vertical motion induced pumping surface float gravity waves through local gradient. uncontaminated signal can be retrieved removing part measured that...
Karst aquifers are crucial for providing fresh water worldwide but also incredibly sensitive to human impact and climate change. This study aims reconstruct the historical levels of karst springs, despite lack data. By combining collected data, we have created a detailed numerical model understand complex behavior aquifers. Our research reveals significant drops in at Longtan Spring, mainly due overuse groundwater inadequate recharge, which is critical success Springs Resurgence project. We...
Abstract Shear wave splitting (SWS) analysis is widely used to provide critical constraints on crustal and mantle structure dynamic models. In order obtain reliable measurements, an essential step visually verify all the measurements reject problematic a task that increasingly time consuming due exponential increase in amount of data. this study, we utilized convolutional neural network (CNN) based method automatically select SWS measurements. The CNN was trained by human‐verified...
Integrated observations were made on the South China Sea shelf at 19°37' N, 112°04' E, under strong wind and heavy raining weather conditions in August 2005. Current data obtained using a moored 150-kHz Acoustic Doppler Profiler, turbulent kinetic energy dissipation rate measured with TurboMapII, temperature was recorded by thermistor chains. Both mixed layer thickness corresponding mean increased after bursts. Average surface 13.4 m pre-wind 22.4 post-wind, average post-wind 4.26 × 10−7...
Abstract The spatiotemporal variability of oceanic fronts in the Indonesian seas was investigated using high-resolution satellite observations. study aimed to understand underlying mechanism driving these and their impact on chlorophyll-a variability. A high value frontal probability found near coasts major islands, exhibiting a distinct seasonal cycle with peaks occurrences during austral winter. distribution generally consistent presence active zones, although significantly positive...
[1] In June 2009, six consecutive observations with duration times of 13 h or 26 were performed at the sea surface outer Hangzhou Bay in East China Sea. Physical (current direction and velocity), hydrological (salinity, suspended particulate matter (SPM) turbidity, total volume mean size flocs), chemical tracer (nutrients, chromophoric dissolved organic matter, nitrogen) data collected. Harmonic analysis that included diurnal, semidiurnal, quarter-diurnal constituents was conducted on time...
Full-waveform inversion (FWI) is capable of providing high-resolution models the elastic parameters subsurface at different scales, including shallow seismic applications. In spite its vast potential, FWI still has certain challenges that need to be addressed, especially for near surface One biggest being defining an initial model. Recent advances in deep learning (DL) algorithms combined with more accessible computing resources allowed us perform direct shear-wave velocity (Vs) model...
Abstract The time window for analyzing local shear-wave splitting (SWS) phases significantly affects the quality of measurements, revealing a noteworthy domain influence. In this study, an approach using convolutional neural network (CNN) is applied to determine end (e), which has similar idea phase-picking CNNs. start 0.5 s before e. Our data set contains 803 human-labeled recorded from three stations located in Ridgecrest, California. These measurements are foreshocks and aftershocks M 7.1...
