Numerous mesoscale eddies occur each year in the South China Sea (SCS), but their statistical characteristics are still not well documented. A Pacific basin‐wide three‐dimensional physical‐biogeochemical model has been developed and result SCS subdomain is used to quantify eddy activities during period of 1993–2007. The modeled results compared with a merged gridded satellite product sea level anomaly by using same identification tracking method. On average, there about 32.9 ± 2.4 predicted...
Coastal upwelling ecosystems are among the most productive in world, meaning that their response to climate change is of critical importance. Our understanding impacts on marine largely limited open ocean, mainly because coastal poorly reproduced by current earth system models. Here, a high-resolution model used examine nutrients and plankton dynamics future California Current System (CCS). The results show increased intensity associated with stronger alongshore winds region, enhanced...
[1] Mesoscale eddies are observed each year in the South China Sea (SCS); however, their contributions to biogeochemical cycles have never been systematically quantified. Here, we use a coupled three-dimensional physical-biogeochemical model evaluate eddy impact. We first track modeled mesoscale SCS and then analyze responses these individually. Compared with basin mean, depth-integrated (0–125 m) chlorophyll, zooplankton, new production, silicate uptake significantly enhanced cyclonic...
Abstract A high‐resolution, 3‐dimensional primitive equation model is used to investigate the cross‐shelf exchange in East China Sea (ECS). Favorable comparisons between field data and simulations from both climatological run hindcast for 2006 indicate that has essential skills capturing key physics of ECS. Temporal spatial variations exchanges are further analyzed. It was demonstrated observations high saline water could be delivered north Changjiang River mouth (near 32°N) as a result...
Abstract Subtropical gyres cover 26%–29% of the world's surface ocean and are conventionally regarded as deserts due to their permanent stratification, depleted nutrients, low biological productivity. Despite tremendous advances over past three decades, particularly through Hawaii Ocean Time‐series Bermuda Atlantic Study, which have revolutionized our understanding biogeochemistry in oligotrophic marine ecosystems, remain understudied. We review current upper North Pacific Gyre, considering...
Abstract Oceanic submesoscale processes are ubiquitous in the North Pacific Subtropical Gyre (NPSG), where biological carbon pump is generally ineffective. Due to difficulties collecting continuous observations, however, it remains uncertain whether episodic can drive significant changes particulate organic (POC) export into mesopelagic ocean. Here we present observations from high-frequency Biogeochemical-Argo floats NPSG, which captured enhanced POC fluxes during intensifying stages of a...
[1] Oceanic eddies are active and energetic southwest of Taiwan. The formation propagation in this area were investigated using 17 year satellite altimeter data. Cyclonic (CEs) anticyclonic (ACEs) often coexisted, but there more CEs than ACEs generated during the period from October 1992 to 2009. stronger and, general, lived longer CEs. occurred winter other seasons, while frequent summer. Compared with direct local wind forcing, Kuroshio path variability appears be a dominant factor for...
Abstract Inferred from the satellite and in situ hydrographic data 1990s 2000s, Kuroshio intrusion into South China Sea (SCS) had a weakening trend over past two decades. Associated with weakened intrusion, loop eddy activity southwest of Taiwan became weaker, whereas water above salinity minimum less saline northern SCS. The sea surface height increased at slower rate compared to other regions SCS because intrusion. Simulations using Regional Ocean Modeling System (ROMS) Pacific model show...
Abstract New evidences were provided that Kuroshio intrusion in winter is able to increase phytoplankton growth the open ocean of northern South China Sea (SCS) based on multiple data sources. Strong fronts due and interactions with SCS water are associated intense upwelling, supplying high nutrients from subsurface increasing productivity frontal region. High chlorophyll more dynamically related these than alongshore wind, wind stress curl, eddy kinetic energy interannual time scale....
Abstract Newly available sea surface salinity (SSS) data from the Aquarius together with in situ hydrographic are used to explore spatial and temporal characteristics of SSS South China Sea (SCS). Using observations as reference, an evaluation daily indicates that there exists a negative bias 0.45 psu for version 3.0 set. The root‐mean‐square difference is about 0.53 after correcting systematic bias, those weekly monthly SSSs 0.29 psu, respectively. Nevertheless, shows reliable freshening...
Abstract The North Pacific Subtropical Gyre (NPSG) is an oligotrophic environment where a number of mesoscale eddies occur. With continuous measurements from Biogeochemical‐Argo (BGC‐Argo) floats, we showed that can significantly affect the subsurface chlorophyll maximum (SCM) and biogenic particles. Different responses SCM to cyclonic anticyclonic those between eddy core edge region were revealed by combining results tracked eddies. variations in particles further shown be statistically...
Typhoons pose great threats to coastal regions, leaving distinctive ocean surface changes along the typhoon track before landing. However, a quantitative description of spatial and temporal patterns typhoon-induced oceanic responses remains unclear. Sixteen years composited data sea temperature (SST) chlorophyll-a (Chl-a) in South China Sea demonstrate that initiate immediately arrival continue increase during its passage. The largest decrease occurred one day after typhoon, leading maximum...
Abstract An unprecedented warm sea surface temperature (SST) anomaly event, namely, the Blob, occurred in northeast Pacific during winter (October–January) of 2013/2014, causing substantial economic and ecological impacts. Here, we explore driving forces Blob from both atmospheric oceanic perspectives show that primarily resulted weak wintertime cooling due to reduced air-sea heat flux transfer ocean atmosphere horizontal advection cold water upper ocean. Both mechanisms were attributed an...
Concurrent inhibition of angiogenesis and immune checkpoints represents a potent therapeutic approach. We conducted phase 2, multicenter, basket study to assess the efficacy safety combination therapy famitinib (anti-angiogenic agent) plus camrelizumab (PD-1 antagonist) in patients with metastatic solid tumors across 11 cohorts (this was registered at Clinicaltrials.gov [NCT04346381]). This report focuses on cohort or advanced colorectal cancer. Eligible patients, who had previously received...
Chlorophyll-a (Chl-a) plays a vital role in assessing environmental health and understanding the response of marine ecosystems to physical factors climate change. In situ sampling, remote sensing, moored buoys or floats are commonly employed methods for obtaining Chl-a science research. Although buoys, could provide accurate data, they limited by spatial temporal resolution. Remote sensing offers continuous broad coverage, while it is often hindered cloud cover South China Sea (SCS). This...
Oceanic submesoscale processes are ubiquitous in the North Pacific Subtropical Gyre (NPSG), where biological carbon pump is generally ineffective. Due to difficulties collecting continuous observations, however, it remains uncertain whether episodic can drive significant changes particulate organic (POC) export into mesopelagic ocean. Here we present observations from high-frequency Biogeochemical-Argo floats NPSG, which captured enhanced POC fluxes during intensifying stages of a front and...
The 234 Th– 238 U pair technique is widely used in estimating particulate organic carbon (POC) flux, typically with a steady-state (SS) assumption. There often temporal bias between the SS-derived and actual POC fluxes caused by neglecting change Th. However, this has not been fully investigated due to lack of continuous sampling Th profiles sediment traps. Here, we develop radioactive trace model built on physical–biogeochemical simulate scavenging water column sinking processes at South...
Abstract Observations suggest that subsurface waters in the northern South China Sea exhibited substantial low‐frequency variability, with a striking decadal change southern limit of 34.6 practical salinity unit (psu) isohaline. Long‐term freshening waters, started 1960, was followed by salinification from 1975, and occurred again 1993 to 2012. The linear trends were −0.0076, 0.0100, −0.0078 psu/yr, respectively. An analysis budget reveals main underlying contributors are horizontal...
Carbon, nitrogen, and chlorophyll are three commonly used variables to quantify phytoplankton productivity. However, owing the complex effect of light, temperature, nutrient, these usually decoupled from each other. By implementing a biogeochemical model that treats carbon, separately in Pacific basin‐scale circulation model, we have investigated physical controls on C:Chl C:N ratios at different scales. The reproduces general features dynamics basin. Model results indicate region dependent...
[1] Mesoscale anticyclonic Haida eddies are proposed to deliver a substantial amount of iron into the Gulf Alaska (GOA) central gyre, where surface waters experience high-nitrate low-chlorophyll conditions. In this study we calculate an averaged upwelling flux dissolved euphotic zone (100 m) 1.17 μmol m−2 d−1 based on observed profiles and modeled eddy dynamics resultant vertical velocities. This estimated eddy-derived supply rate is comparable with new estimates pulsed fertilization rates...
