AbstractThe ocean economic input-output (IO) tables are essential databases for analyzing the ocean economy. However, the IO tables issued by Chinese government’s statistical department adopt the conventional economic sector classifications, which fall short in capturing the heterogeneity of the ocean and land sectors. To fill this gap, we used the stripping coefficient method to construct the ocean ...
AbstractMangroves are a carbon-dense and highly productive ecosystem but can experience massive dieback under environmental extremes. Climatic oscillations, such as the El Niño–Southern Oscillation (ENSO), are major drivers of global climate variability, yet their impact on mangrove growth at the global scale remains uncertain. Here, using long-term satellite observations from 2001 to 2020, we show ...
AbstractMicrobial metabolism plays a critical role in global carbon cycling; however, our understanding of bacterial metabolic processes across the full depth of tropical oligotrophic oceans remains incomplete. The South China Sea (SCS) and Western Pacific (WP), as contrasting oligotrophic environments, provide an ideal setting to investigate this unresolved issue. This study presented a comprehensive ...
AbstractAn increasing number of studies have documented the ecological importance of phago-mixotrophy within phytoplankton communities, especially in open ocean environments. We know less about the distribution and function of such phytoplankton within marginal seas. This study was an investigation of phago-mixotrophy among nanoeukaryotic phytoplankton along a shelf-to-off-shelf transect in the South ...
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....
