The reconstruction of subsurface ocean temperature using sea surface observations and in situ Argo measurements is an important yet challenging task. availability long-term high-resolution remote sensing, combined with advancements deep learning technology, has opened new opportunities for studying (ST) reconstruction. In this study, a novel spatial–temporal Siamese convolutional neural network (SSCNN) proposed to improve the accuracy ST Indian Ocean. First, considering distinctions...

A marine heatwave (MHW) can significantly harm ecosystems and fisheries. Based on a remotely sensed sea surface temperature (SST) product, this study investigated MHWs behaviors in the South China Sea (SCS) throughout warm season (May to September) from 1982 2020. The distributions of three MHW indices used showed significant latitudinal variations: more frequent, longer, intense appear northern SCS, less shorter, weaker southern SCS. Using empirical orthogonal function (EOF) method, we...

Abstract High‐turbidity events (HTEs) are common phenomena in shallow‐water environments that can alter ecological interactions. The relative contributions of river input (external loading) vs. resuspension (internal to the occurrence, duration, and influenced areas HTEs not fully understood most systems, owing lack long‐term, source‐specified sediment maps. Using a Finite Volume Community Ocean Model‐based wave‐current forced model, we investigated dynamics shallow, river‐dominated Western...

Abstract Interbasin exchange and interannual variability in Lake Erie's three basins are investigated with the help of a three‐dimensional unstructured‐grid‐based Finite Volume Coastal Ocean Model (FVCOM). Experiments were carried out to investigate influence grid resolutions different sources wind forcing on lake dynamics. Based calibrated model, we sensitivity dynamics major external forcing, seasonal climatological circulation patterns presented compared observational data existing model...

Argo observations are spatially sparse and temporally uneven, whereas satellites can provide high-resolution continuous at the sea surface. The reconstruction of subsurface thermohaline structure using multi-source remote sensing data is thus great significance for investigating ocean interior dynamics. Aiming existing problems temporal feature extraction nonlinear relationship fitting, this paper proposes a multivariate self-attention network (MTSAN) to effectively reconstruct temperature...

Abstract Although the significance of surface gravity waves has been consistently emphasized in previous limnetic studies, roles wave‐current interactions lake dynamics are not sufficiently understood due to lack high‐resolution wave information. With a two‐way coupled hydrodynamic and model system, this study investigated how Lake Erie impacted by wave‐induced radiation stresses on seasonal‐mean episodic scales. The results showed that stress was same as or an order magnitude larger than...

Abstract Wind‐wave interactions have been broadly investigated for their great implications on air‐sea momentum transfer, whereas our knowledge those forced by typhoons (hurricanes) is still limited. Accordingly, relationships between wind and wave characteristics were analyzed using observations the northern South China Sea during four typhoons. An empirical wind‐wave model was proposed typhoon‐induced seas which exhibits satisfactory skills in predicting significant heights ( ). Meanwhile,...

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...

Wave climate in the northern South China Sea (SCS) was accessed during 1990-2020 based on a high-resolution wave model, encompassing evaluation of contributions monsoon and tropical cyclones under impact ENSO activities. Using Gaussian mixture SCS divided into five subareas according to characteristic variations, pronounced seasonality observed both mean extreme significant heights (Hs) across all subregions. The highest  occurred near Luzon Strait year round, with nonnegligible...

Globally, marine heatwaves (MHWs) are becoming more common, intense, and longer-lasting. They could have a large ecological societal impact when compounded by low oxygen concentrations or high acidity. Here, using high-resolution satellite product reanalysis datasets, we investigated the characteristics of MHW at northern Yellow Sea (NYS) during mid-summer 2018 driving mechanisms large-scale atmospheric circulations. Results showed that in (lasting from 26 July to 18 August 2018) had been...

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....
