Abstract

Coastal monitoring is essential for environmental conservation, risk management, sustainable development, and safety operation of maritime activities such as navigation. However, the extent of monitoring systems is usually limited by their elevated cost and complex use and maintenance. This paper presents the development and testing of a new low-cost and versatile instrument for measuring water column pressure in dynamic environments. This instrument -named BlueLog- can measure gravity waves, tides, and water levels in various aquatic environments due to its versatile temporal resolution from 1 to 10 Hz. It can also be used for wave flumes experiments in the laboratory. Among its outstanding characteristics, BlueLog is configured in open-source language, its batteries are rechargeable and commercially available, includes a modular housing that allows replacing the pressure sensor in case of damage, and a set of LED lights indicates the status of communication, configuration, and sampling. As demonstrated here by a set of laboratory and field tests, BlueLog is ready and open to be validated in different scientific and technical applications. It is expected to serve as a low-cost and easy-to-use instrument for marine and coastal environments.
