Measuring Ocean State with Floating Buoys
A Floating Ocean Sensor Monitoring Local Conditions on Maui
A new project on Maui, Hawaii, has created a floating ocean sensor to monitor local ocean conditions. This sensor, paired with a Wio-SX1262 radio kit, sends LoRa signals over longer distances, allowing for real-time data collection.
The sensor measures the water's conditions and the motion of the waves. Its housing is made of 3D printed material, ensuring durability and waterproofing. The rest of the sensor's electronics are housed in a waterproof Pelican case. The sensor's onboard WiFi and Bluetooth connections are not used for sending signals due to practicality issues.
The project encourages individuals involved in ocean science to share their work, with a tipsline provided for this purpose. It demonstrates the use of off-the-shelf components for a useful purpose, contributing to a larger dataset for further analysis.
The specific number of sensors in the proposed grid is not mentioned. However, the potential benefits of the project for ocean science are implied. The data collected by the floating ocean sensor could be more useful when combined with data from a grid of similar sensors.
Similar citizen science ocean projects have been executed successfully in the past. Examples include the BlueDOT project and low-cost water level monitoring initiatives employing ultrasonic sensors.
The BlueDOT project involves scuba divers collecting ocean temperature data using their dive computers, combined with data from permanently deployed high-precision temperature sensors at reference dive sites. This allows scientists to calibrate and enhance temperature data accuracy, facilitating monitoring of marine heat waves and ocean temperature changes related to climate change.
Low-cost water level monitoring projects use affordable, easy-to-install floating sensors for real-time sea and river water level monitoring. These projects democratize environmental observations and support climate risk reduction and forecasting model validation.
While the Maui project focuses on local ocean conditions, it aligns with these broader citizen science initiatives, enhancing ocean monitoring and climate-related environmental research. The project's success is not specified in the given context, but its potential impact on ocean science is promising.
