State Key Laboratory of Satellite Ocean Environment Dynamics, Second Institute of Oceanography, Ministry of Natural Resources of the People's Republic of China, Hangzhou 310012, China; Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou), Guangzhou 511458, China.

Information about sea surface nitrate (SSN) concentrations is crucial for estimating oceanic new productivity and for carbon cycle studies. Due to the absence of optical properties in SSN and the intricate relationships with environmental factors affecting spatiotemporal dynamics, developing a more representative and widely applicable remote sensing inversion algorithm for SSN is challenging. Most methods for the remote estimation of SSN are based on data-driven neural networks or deep learning and lack mechanistic descriptions.

Article Synopsis
  • Coastal bays are important hubs for dissolved organic matter (DOM) cycling, and this study investigates how mariculture activities, specifically fish, seaweed, and abalone farming, affect DOM in Sansha Bay, China.
  • Through seasonal sampling and lab experiments, researchers identified three types of fluorescent dissolved organic matter (FDOM), with seaweed culture significantly influencing the DOM pool by producing high amounts of protein-like C1.
  • The study concludes that while fish and abalone farming impact DOM differently, seaweed culture plays a key role in the seasonal generation of DOM and the potential for carbon sequestration, which is crucial for understanding the carbon dynamics of mariculture.
