波浪产生的水流、相关的水动力以及由它们产生的扰动在确定近岸沿海生态系统的结构和健康方面发挥着关键作用。波浪产生的振荡运动增加了向底栖生物输送营养物和食物，并且可以增强垂直混合，以促进将幼虫和孢子输送到海底。与此同时，波浪扰动可以消除个体和生物量，对重要的沿海生态系统及其生物多样性产生深远影响。旨在测量波浪特征和波浪能影响的商业仪器的购买和部署成本可能很高，限制了它们的大量使用或在可能丢失的地区使用。我们开发了一种基于 Arduino 微控制器的廉价开源压力传感器数据记录器，可用于表征持续数月部署的波浪条件。我们的设计标准围绕简单、耐用、低成本和研究人员易用性。开放式波高记录仪 (OWHL) 采用普遍存在的聚氯乙烯 (PVC) 管道，主要采用现成材料制成，可以在大学环境中使用基本车间工具进行制造。在现场测试期间，OWHL 的性能与商业基于压力的波高数据记录仪相当，从而为扩大这些传感器的使用范围创造了机会，在这些应用中，充分的空间复制或仪器丢失的风险将导致成本过高。
Wave-generated flows, associated hydrodynamic forces, and disturbances created by them play critical roles in determining the structure and health of near-shore coastal ecosystems. Oscillatory motions produced by waves increase delivery of nutrients and food to benthic organisms, and can enhance vertical mixing to facilitate delivery of larvae and spores to the seafloor. At the same time, wave disturbances can remove individuals and biomass with far-reaching effects on critical coastal ecosystems and the biodiversity within them. Commercial instruments designed to measure wave characteristics and the effects of wave energy can be expensive to purchase and deploy, limiting their use in large quantities or in areas where they may be lost. We have developed an inexpensive open-source pressure transducer data logger based on an Arduino microcontroller that can be used to characterize wave conditions for deployments lasting multiple months. Our design criteria centered around simplicity, longevity, low cost, and ease of use for researchers. Housed in ubiquitous polyvinylchloride (PVC) plumbing and constructed primarily with readily available materials, the Open Wave Height Logger (OWHL) can be fabricated in a college setting with basic shop tools. The OWHL performs comparably to commercial pressure-based wave height data loggers during tests in the field, creating the opportunity to expand the use of these sensors for applications where sufficient spatial replication or risk of instrument loss would otherwise be cost prohibitive.
