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.

Article Synopsis
  • * Using a Bayesian maximum entropy approach, researchers integrated organic carbon data from different sediment depths to create a 3D model, achieving high estimation accuracy with carbon storage density maps at 1-meter resolution.
  • * Results showed a higher carbon density in older stable zones compared to rapidly expanding areas and identified an average carbon burial rate of 266 g C/m/yr, while suggesting that the BME framework could be adapted for estimating carbon storage in various blue carbon ecosystems.

Coastal blue carbon ecosystems offer promising benefits for both climate change mitigation and adaptation. While there have been widespread efforts to transplant mangroves from the tropics to the subtropics and to introduce exotic saltmarsh plants like Spartina alterniflora in China, few studies have thoroughly quantified the chronological records of carbon sequestration with different organic carbon (OC) sources. To understand how variations in OC sources can affect the carbon sequestration potential of coastal wetland environment over time, we conducted a study on typical islands with two scenarios: S.

Sediments are considered to be important sinks of microplastics, but the enrichment process of microplastics by blue carbon ecosystems is poorly studied. This study analyzed the spatial distribution and temporal changes, assessed the polymer types and morphological characteristics of microplastics in sediments of five ecosystems, i.e.

Sediments of blue carbon vegetation are becoming a sink of natural and anthropogenic pollutants, such as polycyclic aromatic hydrocarbons (PAHs). However, the extent to which PAHs are accumulated and varied in blue carbon sediments, and the impact of blue carbon vegetation on the accumulation and retention capacity of PAHs, have been poorly explored. This study examines the sedimentary records of PAHs in profiles from mangrove plantation, saltmarsh, and mudflat in Ximen Island and Maoyan Island of Yueqing Bay, China.
