The intertidal zone is a harsh environment for marine life as conditions are often both extreme and variable. A wide range of sessile organisms are partially or fully emersed (exposed above the water line) during low tide. In the tropics, when corals are emersed, high light and temperature can be detrimental to their survival. To date, there is no commercially-available logger that can detect periods of emersion, information that is useful for marine research and for coastal resource management. Here, we present a low-cost Arduino-based multi-parameter logger called 'EmerSense' which can detect instances of emersion while simultaneously recording light and temperature profiles. We describe the different steps involved in fabricating EmerSense, including hardware construction and software design, and discuss the results of our field testing at an intertidal coral reef in Singapore.
潮间带对海洋生物来说是一个恶劣的环境，因为其条件往往既极端又多变。在退潮时，各种各样的固着生物会部分或完全露出水面（暴露在水线以上）。在热带地区，当珊瑚露出水面时，强光和高温可能对其生存有害。迄今为止，还没有一种商用记录仪能够检测出露出水面的时间段，而这些信息对海洋研究和沿海资源管理是有用的。在此，我们展示了一种基于低成本 Arduino 的多参数记录仪，名为“EmerSense”，它能够检测出露出水面的情况，同时记录光照和温度变化曲线。我们描述了制造 EmerSense 所涉及的不同步骤，包括硬件构建和软件设计，并讨论了我们在新加坡一个潮间带珊瑚礁进行现场测试的结果。
