However, the underlying dynamics of ECFB modulating KE transfer still lack thorough investigation. In this study, the ECFB is found to substantially reduce the inverse KE transfer, with this reduction extending to a depth of 500 m in the Kuroshio Extension. Within the surface boundary layer (SBL), the weakened inverse KE transfer is attributed to the enhanced EKE loss to the atmosphere and reduced conversion from eddy available potential energy (EAPE) to EKE. Below the SBL, conversion from EAPE to EKE becomes the sole dominant driver of the reduced inverse KE transfer. On the one hand, the negative wind work induced by ECFB enhances EKE loss within the SBL. On the other hand, the weakened meander fronts and the consequent suppressed baroclinic instability are responsible for the weakened conversion from EAPE to EKE under ECFB. Under ECFB, the growth rate of the baroclinic instability decreases by 12%. The reduction in meander fronts is caused by the diminished meander KE and the associated weakening of the strain rate, which is due to the pressure work divergence resulting from Ekman pumping under ECFB.</p>","PeriodicalId":54340,"journal":{"name":"Journal of Geophysical Research-Oceans","volume":"130 2","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This decadal variability is highly correlated with multiple Pacific climate indices, suggesting that this climate variability influences internal tides via coupled ocean-atmosphere mechanisms. The surface expression of variations in the M₂ internal tide yield correlated variability between MSL and M₂ offshore and onshore. The M₂ signals at all tide gauges have stronger relationships to MSL in the altimetry era (1992–2023) than their respective full records, and both factors show stronger connections to climate variations in recent years. The magnitudes of the climate-induced tidal variations are on the order of 10% on top of MSL variability and long-term steric sea level rise.

This study examines progression of OA in the Canada Basin, focusing on expansion of surface and subsurface aragonite undersaturated waters (USW). Surface USW thickness increased from 0 m in 2003 to 19 ± 2 m in 2019. This change was due to freshening until 2012, and then due to increased uptake of anthropogenic CO₂ after 2012. In the subsurface layer, USW thickness increased from 94 ± 6 m in 2003 to 136 ± 11 m in 2019. This change is primarily attributed to OA in upstream shelf regions, driven by increased CO₂ uptake and respiration, with some contribution from thickening in the Pacific Winter Water layer. The combined thickening of surface and subsurface USW layers increased the percentage of USW in the 0–250 m water column from 38 ± 3% in 2003 to 62 ± 5% in 2019. Because of the concurrent deepening of the water masses due to the enhanced Beaufort Gyre, the replacement of oversaturated water to USW occurred mostly at the subsurface layer below 190 m. The thickness of the oversaturated layer between surface and subsurface USWs remained almost unchanged. If Beaufort Gyre weakens in the future, it would bring subsurface USW shallower, potentially affecting marine life.</p>","PeriodicalId":54340,"journal":{"name":"Journal of Geophysical Research-Oceans","volume":"130 2","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143424166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study constructs the Pacific surface currents along the equator (every 0.25° of longitude) from 1993 to 2017 (at daily intervals) using a feedforward neural network and multiple sea surface variables, showing superior correlations and root mean square errors with in situ measurements. Based on this product, the ISOs explain ∼10%–30% and ∼20%–50% of the zonal and meridional current variance, respectively, exhibiting disparate characteristics in the western and eastern Pacific. The Madden-Julian Oscillation (MJO) governs the western basin, where the ISOs are more intense during El Niños. Particularly, significant ISOs in zonal currents (−0.25–0.28 m s⁻¹) span nearly the entire basin during EP-El Niño summers and winters; the intensity becomes even stronger (−0.27–0.32 m s⁻¹) for CP-El Niño winters, as the MJO convection center thrives throughout the life cycle. The intraseasonal meridional currents, though much weaker, extend eastward up to ∼150°W during EP-El Niño winters. As for the eastern basin, the ISOs arise primarily from baroclinic instability and propagate westward with the phase speed and the domain being fastest and most widespread for La Niñas and vice versa for El Niños.

The results revealed that the phytoplankton communities in the monsoon interval (MI) period significantly differed from those in monsoon periods. Specifically, the phytoplankton communities exhibited the highest diversity owing to the pronounced environmental heterogeneity in the sampling time of MI. However, the total abundance of phytoplankton (4.2 ± 4.0 × 10³ cells/L) was the highest in the northeast monsoon (NEM) period due to the nutrient-rich conditions caused by strong vertical mixing possibly induced by the western boundary current.

Additionally, we conduct a sensitivity analysis to identify the minimum necessary model configuration for capturing the impact of kilometer-scale circulation on connectivity metrics. Our results reveal year-round low connectivity potential between mesophotic areas with high seasonal heterogeneity in transport direction and dispersal distances due to the high variability of the currents fields.

A better understanding of the mechanisms controlling the seasonal variance of SSS could provide directions for improving the representation of the SSS seasonal cycle amplitude in these models. In this work, we use a novel framework, based on seasonal salinity variance budget (SVB), which we apply to the Estimating the Circulation and Climate of the Ocean (ECCO) state estimate, to study the mechanisms controlling the variance of seasonal SSS in the tropical oceans. Our findings reveal that oceanic advection, vertical diffusion, and freshwater fluxes from rivers and precipitation all play an important role in controlling the amplitude of the seasonal cycle, but their impact varies regionally. The SVB framework effectively distinguishes between “source” (mechanisms that enhance variance) and “sinks” (mechanisms that dampen variance). We show that vertical diffusion acts as the primary sink across most regions, except for the eastern Arabian Sea where precipitation dominates as the main sink. In other regions of the tropical oceans, precipitation and river runoff act as sources of variance. The effect of the advective term on the SSS variance is shown to be mainly the sum of two terms—first, a term associated with the spatial redistribution of the variability by the eddy-parametrized oceanic circulation, and second, a term associated to a transfer of salinity variance between the time mean and seasonal circulations.</p>","PeriodicalId":54340,"journal":{"name":"Journal of Geophysical Research-Oceans","volume":"130 2","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1029/2024JC021455","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143388977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs a numerical model to investigate the effects of upwelling over the northeastern shelf of the South China Sea and its barotropic influences on the dynamics and freshwater transport of a medium-scale river plume. In a model experiment with extremely weakened upwelling (tiny upwelling case), plume water spreads across a wide coastal region driven by upwelling-favorable winds. With the barotropic effects of upwelling, plume water occupies a much smaller area, and the alongshore geostrophic current is enhanced. In the Control Run, plume water disperses further offshore in a stratified seawater column, as the Ekman layer thins and the offshore Ekman current intensifies in the upwelling region. The upwelling process not only accelerates the downwind advection of offshore extended far-field plume water due to the drop in coastal sea level but also continually upwells high-salinity water from the lower layer to the upper layer, enhancing mixing with plume water and leading to a smaller river plume area. Under upwelling-favorable wind conditions, freshwater is primarily transported offshore in tiny upwelling case, while the proportion of downwind freshwater transport increases in the Control Run or the barotropic case.
