Although atmospheric transport and deposition could be an important pathway of terrestrial pollutants to the ocean, little information concerning presence distribution these suspended microplastics in marine air is available. We investigated, for first time, occurrence (SAMPs) west Pacific Ocean. In this study, spatial distribution, morphological appearance, chemical composition were studied through continuous sampling during a cruise. SAMPs abundance ranged from 0 1.37 n/m3, median 0.01...
A new technique involving large-volume (10 m3) samples of seawater was used to determine the abundance microplastics (MPs) in water column West Pacific Ocean and East Indian Ocean. Compared conventional sampling methods based on smaller volumes water, data yielded values for deep-water that were at least 1–2 orders magnitude lower. The suggested limited bulk currently surface are insufficient obtain accurate estimates MP deep water. Size distribution indicated lateral movement MPs into...
Abstract Conventional wisdoms on river plume dynamics suggest that a down‐shelf buoyant coastal current will ultimately be trapped at specific depth, is, the trapping as constrained by riverine outflow and offshore bottom Ekman transport. Theoretically, prerequisite is necessary to form stable bottom‐trapped plume. In this study an alternative described carrying out modeling Zhe‐Min Coastal Current (ZMCC). Buoyant water from Changjiang River major factor driving ZMCC, common in plumes;...
Building on top of the success in AI-based atmospheric emulation, we propose an ocean emulation and downscaling framework focusing high-resolution regional over Gulf Mexico. Regional presents unique challenges owing to complex bathymetry lateral boundary conditions as well from fundamental biases deep learning-based frameworks, such instability hallucinations. In this paper, develop a autoregressively integrate ocean-surface variables Mexico at $8$ Km spatial resolution without unphysical...
Abstract Studies suggest a strong link between low‐frequency sea level variability in the South Atlantic Bight (SAB) and open ocean dynamics. However, mechanisms driving this connection remain unclear. By analyzing high‐resolution, three‐dimensional baroclinic reanalysis, we identify pathway that links dynamics to SAB coastal through shelf edge near Cape Hatteras. Gulf Stream meanders region induce fluctuations propagate along entire shelf. Using an idealized barotropic model, further...
While data-driven approaches demonstrate great potential in atmospheric modeling and weather forecasting, ocean poses distinct challenges due to complex bathymetry, land, vertical structure, flow non-linearity. This study introduces OceanNet, a principled neural operator-based digital twin for circulation. OceanNet uses Fourier operator predictor-evaluate-corrector integration scheme mitigate autoregressive error growth enhance stability over extended time scales. A spectral regularizer...
Abstract. Many meteorological and oceanographic processes throughout the eastern United States western Atlantic Ocean, such as storm tracks shelf water transport, are influenced by position warm sea surface temperature of Gulf Stream (GS)- region's boundary current. Due to highly nonlinear associated with GS, predicting its meanders frontal have been long-standing challenges within numerical modeling community. While weather climate communities begun turn data-driven machine learning...
Methane hydrates on continental margins sequester substantial amounts of methane. Ocean warming often triggers hydrate dissociation, influencing global climate and marine ecosystems. Here we use ocean reanalysis to investigate bottom heatwaves affecting methane seeps at the Northwest Atlantic margin. These are driven by downward displacement subsurface isopycnals that brings anomalously warm water seafloor, which frequently lacked surface expressions. The isopycnal anomalies generated...
Riverine export into the ocean contributes greatly to global microplastic (MP) contamination, yet little is known about dynamic variation of MP in water columns estuarine systems. To increase our understanding this process, we sampled during four seasons at ebb and flood tides saltwater intrusion node Yangtze River Estuary, covered dry wet seasons. According seasonal abundance MP, its vertical distribution, current velocity calculate full column net flux. Also, a tide-model microplastics...
