Improved Isotope‐Based Source Apportionment of Iron Reveals Strong Anthropogenic Input in the North Pacific Ocean

Tianle Zhang, Mei Zheng, W. Guan, Junyi Liu et autres

Abstract The iron cycle is a fundamental component of the Earth system. Growing evidence indicates that anthropogenic emissions can significantly perturb the iron cycle, beyond the influence of natural dust. The iron isotope technique has emerged as a powerful tool for quantifying …

Physical dynamics modulate deep‐sea carbon flux in the western Pacific marginal sea

Chao Xu, Yibin Huang, Xiaogang Xing, Guoqiang Qiu et autres

Abstract Deep‐sea particulate organic carbon (POC) flux sustains deep‐sea ecosystems and contributes significantly to long‐term carbon sequestration. However, our understanding of its magnitude and governing mechanisms remains poorly constrained due to the limitations of traditional observational approaches. Using a biogeochemical profiling float …

Contrasting climate oscillations impacts on phytoplankton in the western and eastern tropical Pacific

Lina An, Edward A. Laws, Xin Liu, Ruiying Chen et autres

Climate oscillations like the El Niño-Southern Oscillation and Pacific Decadal Oscillation significantly impact marine ecosystems. Traditionally, warm events are thought to suppress nutrient availability, reduce phytoplankton biomass, and change community structure. However, using two decades of field observations, remote sensing, Copernicus reanalysis, …

Source Apportionment of Atmospheric Iron in Northern China Based on 3‐Year Continuous Measurements

Tianle Zhang, Yaxin Xiang, Yue Liu, Caiqing Yan et autres

Abstract Atmospheric iron (Fe) impacts atmospheric chemistry and marine ecosystems. However, the scarcity of long‐term observations limits insights into its source variations that may reflect emission controls. From September 2016 to December 2019, Fe in atmospheric fine particles (PM 2.5 ) was …

Spatial Variation of Upper Ocean Chlorophyll‐ a Response Across the Track of a Typhoon in the Northwest Pacific

Sheng Lin, Yuntao Wang, Tanuspong Pokavanich, Sana Ben Ismail et autres

Abstract Typhoons typically enhance phytoplankton biomass in the upper ocean, as evidenced by elevated sea surface chlorophyll ‐a concentrations (Chl‐ a ). However, subsurface Chl ‐a responses remain debated, leading to uncertainty about whether vertically integrated Chl ‐a over upper depth increases …

Distinct Spatiotemporal Patterns of Atmospheric Total and Soluble Iron from Three Sources Revealed by Shipboard Online Observations in the Northwest Pacific

Tianle Zhang, Yaxin Xiang, Bo Zhu, Xiaohong Yao et autres

Abstract. Non-dust emissions have been increasingly recognized as important contributors to atmospheric iron (Fe), influencing marine productivity through enhanced bioavailable Fe inputs. However, accurately quantifying the contributions and spatiotemporal variability of non-dust sources remains challenging due to relatively low time-resolution of traditional …

Seasonal Variability of Phytoplankton Following Extreme Aerosol Events in the Western Subarctic Pacific

Haoran Zhang, Yuntao Wang, Peng Xiu, Wentao Ma et autres

Abstract Phytoplankton growth in the western subarctic Pacific is strongly influenced by the supply of bioavailable iron (BFe), which is primarily regulated by atmospheric deposition that was most prominent in spring, weak in summer, and negligible in other seasons. The seasonal phytoplankton …
