我们提出了现场数据和文献数据，以突出低潮降雨对潮间带景观中颗粒有机碳（POC）再分布的影响。将不同但相关的研究报告的POC交换标准化为风暴引起的交换率（gPOC m−2 mmRain−1）并进行比较。结果表明，这些潮间带区域对降雨有特征性的响应，平均通量为0.040 ± 0.038 gPOC m−2 mmRain−1。此外，低潮降雨可以携带和重新分配7-54%的年度沉积POC积累，或12-75%的年度POC输出，根据目前的外向评估。最后，我们提供了一个概念模型，通过潮间带景观的层次结构描述降雨驱动的POC交换的可变性，以及POC通量的观测结果如何在潮间带景观中发生变化。这一信息应用于指导潮间带降雨持续工作的取样策略。
We present field data and data from the literature to highlight the effects of low‐tide rainfall on particulate organic carbon (POC) redistribution in intertidal landscapes. The POC exchanges reported from disparate but related studies were standardized to a storm‐induced exchange rate (gPOC m−2 mmRain−1) and compared. Results show that these intertidal areas have a characteristic response to rainfall with an average flux of 0.040 ± 0.038 gPOC m−2 mmRain−1. Further, low‐tide rainfall can entrain and redistribute 7–54% of annual sedimentary POC accumulation, or 12–75% of annual POC export, based on current outwelling assessments. Finally, we provide a conceptual model describing the variability of rainfall‐driven POC exchange through the hierarchical structure of intertidal landscapes and how observations of POC flux can be expected to change across the intertidal landscape. This information should be used to guide sampling strategies for continued intertidal zone rainfall work.
