AbstractOceanic cycling of arsenic (As) is closely linked to that of nutrient and trace metal elements such as phosphorus (P) and iron (Fe), primarily due to similar particle-reactivity of As and P and their association with particulate carriers including Fe (oxyhydr)oxides. However, this particle scavenging effect is rarely reflected in seawater depth profiles of total dissolved inorganic As (DAs)...
SummaryFinancial institutions, especially leading asset managers that play critical roles in allocating financial flows, are essential for climate change mitigation. Herein, we evaluate portfolio carbon footprints, which are the greenhouse gas (GHG) emissions enabled by equity investment, of the 500 leading global asset managers. We find that the volume of financed GHG emissions increased from 8.0 ...
AbstractThe large-scale oceanic gyre circulation in the Pacific regulates its temperature, salinity and nutrient flow, profoundly influencing the biological environment and climate. However, how gyres evolved during the warm Eocene, with its different coastline configurations, remains unknown. Here, we investigate the response of Pacific gyre circulation during the warm early Eocene using eight models ...
Earth's deep ocean holds a vast reservoir of dissolved organic carbon, traditionally considered old and resistant to microbial degradation. Radiocarbon analyses indicate the hidden occurrence of younger dissolved organic carbon components, assumed to be accessible to deep-sea microorganisms but not yet demonstrated. Using compound-class radiocarbon analysis, molecular characterization, and ...
Macroalgae aquaculture has been increasingly recognized as a promising nature-based solution to enhance carbon sinks towards climate change mitigation. However, a limited understanding of the temporal patterns of air-sea carbon dioxide (CO2) fluxes and their environmental controls across time scales poses an enormous obstacle to the carbon sink potential assessment of macroalgae aquaculture....
AbstractAccurately predicting algal blooms remains a critical challenge due to their dynamic and non-stationary nature, compounded by high-frequency fluctuations and noise in monitoring data. Additionally, a common issue in time-series forecasting is data replication, where models tend to replicate historical patterns rather than capturing true future variations, leading to inaccurate forecasts during ...
AbstractOcean acidification caused by increasing anthropogenic CO2 is expected to impact marine phytoplankton productivity, yet the extent and even direction of these changes are not well constrained. Here, we investigate the responses of phytoplankton community composition and productivity to acidification across the western North Pacific. Consistent reductions in primary production were observed ...
AbstractCoastal oceans, traditionally seen as a conduit for transporting atmospheric carbon dioxide (CO2)–derived anthropogenic carbon (CANT) to open oceans, exhibit complex carbon exchanges at their interface. South China Sea (SCS) exemplifies this complexity, where interactions with the Pacific, particularly through Kuroshio intrusion, challenge the understanding of CANT source and variabili...
