Marine particles play a key role in the cycling of most elements in the ocean. Particles are typically operationally defined by their collection method and, therefore, span a wide size range, within which chemical properties and interactions may be heterogeneous. The 12 papers in this collection address the challenges associated with studying particles in the marine environment with new types of chemical measurements, broadened oceanographic surveys, and novel sampling, experimentation, and modeling methods. Together, this collection of papers helps to fill critical gaps in our knowledge of the role of particles and elements in marine biogeochemical cycles.

海洋颗粒化学：对生物地球化学循环和颗粒出口的影响

海洋颗粒在海洋中大多数元素的循环中起着关键作用。颗粒通常由其收集方法在操作上定义，因此，跨较大的尺寸范围，在该范围内化学性质和相互作用可能是异质的。此合集中的12篇论文解决了与通过新类型的化学测量，扩大的海洋学调查以及新颖的采样，实验和建模方法研究海洋环境中的粒子相关的挑战。总之，这些论文集有助于填补我们对颗粒和元素在海洋生物地球化学循环中的作用的认识方面的关键空白。
