Building on a summary of how turbulence influences biological systems, we reviewed key phytoplankton-turbulence laboratory experiments (after Peters and Redondo in Scientia Marina: Lectures on plankton and turbulence, International Centre for Coastal Resources, Barcelona, 1997) and Peters and Marrasé (Marine Ecology Progress Series 205:291–306, 2000) to provide a current overview of artificial turbulence generation methods and quantification techniques. This review found that most phytoplankton studies using artificial turbulence feature some form of quantification of turbulence; it is recommended to use turbulent dissipation rates (ε) for consistency with physical oceanographic and limnological observations. Grid-generated turbulence is the dominant method used to generate artificial turbulence with most experiments providing quantified ε values. Couette cylinders are also commonly used due to the ease of quantification, albeit as shear rates not ε. Dinoflagellates were the primary phytoplanktonic group studied due to their propensity for forming harmful algal blooms (HAB) as well as their apparent sensitivity to turbulence. This study found that a majority of experimental setups are made from acrylate plastics that could emit toxins as these materials degrade under UV light. Furthermore, most cosm systems studied were not sufficiently large to accommodate the full range of turbulent length scales, omitting larger vertical overturns. Recognising that phytoplankton-turbulence interactions are extremely complex, the continued promotion of more interdisciplinary studies is recommended.

人工产生的湍流:生理学纳米,微观和中观实验的综述

在总结湍流如何影响生物系统的基础上,我们回顾了关键的浮游植物湍流实验室实验(在Peters和Redondo在Scientia Marina中进行:浮游生物和湍流的讲座,国际海岸资源中心,巴塞罗那,1997年)和Peters和Marrasé(海洋) Ecology Progress Series 205:291–306,2000),提供了人工湍流产生方法和量化技术的最新概况。这篇评论发现,大多数利用人工湍流进行的浮游植物研究都以某种形式的湍流量化为特征。建议使用湍流耗散率(ε),以与物理海洋学和森林学观测保持一致。网格生成的湍流是用于生成人工湍流的主要方法,大多数实验都提供了定量的ε值。尽管剪切速率不是ε,但由于易于量化,通常也使用Couette钢瓶。鞭毛藻是研究的主要浮游植物类,因为它们倾向于形成有害藻华(HAB),并且对湍流具有明显的敏感性。这项研究发现,大多数实验装置是由丙烯酸酯塑料制成的,因为这些材料在紫外线下会降解,因此它们可能会释放出毒素。此外,大多数研究的宇宙系统都没有足够大到无法容纳整个湍流尺度的范围,因此没有较大的垂直倾覆。认识到浮游植物与湍流的相互作用极为复杂,因此建议继续推广更多的跨学科研究。
