Using sensor data for numerical models

Published:

Sensor data have become an important tool in oceanographic science in recent years. Their low cost and relative ease of production have made them an invaluable tool in getting more information about the complex dynamical systems that govern the ocean. Recent additions include, but are not limited to microSWIFT , OpenMetBuoy (OMB) and MELODI. And while these sensors are great, the cost still lies at about 1000 USD due to the need for robust communication using technologies like Iridium and GSM. We aim to create a cheap and open source buoy to measure how the water flows in coastal environments such as a fjord. In these environments, we hope to be able to transmit the data using Long Range Wide Area Network (LoRaWAN) technology, which is both cheaper and less power hungry than the aforementioned GSM and Iridium technologies.
