The Sonic Kayak allows such data to be collected at fine scales that are difficult or impossible to obtain using existing off-the-shelf research equipment, and in areas that can be hard to reach including shallow waters or close to shores/cliffs.
Sea temperatures are typically measured using static sensors attached to buoys or other structures, or using low resolution satellite observations, while underwater sound is usually collected using sensors attached to the seabed, drifting devices, or towed sensors on motored research vessels (these sensors are discussed in more detail in Griffiths et al. Vessels produce underwater noise at a range of frequencies depending on their size for large ships this noise is predominantly below 100 Hz, while small boats usually produce underwater noise at higher frequencies, with concentrations around 1 kHz ( Figure 2 in Duarte et al., 2021). Anthrophony (human-made underwater noise) has been increasing since the industrial revolution and originates from a range of sources ( Duarte et al., 2021), the most pervasive of which is from shipping. The Sonic Kayak Version 1 sensors for water temperature and underwater sound offer new opportunities for data collection in climate change and anthropogenic noise pollution research. Data is sonified in real time through an on-board speaker, allowing the paddler to hear the data as it comes in, and to identify or follow interesting occurrences such as temperature gradients. 2011), was an additional feature of the original version. Sonification, the process of conveying information by using non-speech sounds ( Dubus & Bresin 2013, Hermann et al.
2017) was equipped with temperature sensors and a hydrophone, recording the water temperature every second and underwater sound continually, together with the GPS coordinates, time and date. The Sonic Kayak Version 1 ( Griffiths et al. The equipment is designed to fit onto any model of kayak. The Sonic Kayak is an open source technology project for gathering environmental data from marine, estuarine, river or lake environments, which can then be mapped at a fine scale. A similar initiative, the Smartfin ( ) is close in its aims, but is specific to surfboards and stand-up-paddleboards its electronics are embedded within a fin and currently only measures temperature it is not open source so it is not available for people to build or develop themselves ( Brewin et al. Our development, the Sonic Kayak system, sets itself apart from these projects as the environmental data it collects is automatically geolocated and can be collected while moving, allowing very quick mapping without the need for multiple sets of equipment.

Examples include a water quality sensor developed by Bas Wijnen et al ( 2014) that has been technically verified against professional equipment and the Sensor.Community air quality project, currently producing air quality data globally from open source particulate matter equipment ( ). Low-cost open source and open hardware environmental sensors are proliferating and becoming more reliable. The ability to collect high quality environmental data inexpensively using open source equipment aids transparency, scientific reproducibility, and lowers cost barriers in science.
We believe the Sonic Kayak system offers particular promise for citizen science and environmental activism, and allows professional researchers to gather data that was previously difficult or impossible to We present proof-of principle data for the first time for all the sensors, demonstrating how the system can be used for environmental mapping, and discuss potential future applications and adaptations. The data being collected by the sensors is sonified (turned into sound) in real-time, allowing the paddler to hear the data as they are collecting it, making it possible to locate and follow interesting occurrences. All sensors record continually, and the GPS location, time and date are also stored for every data point, allowing fine-scale environmental data mapping. Here we outline the design and integration of two new sensors, for underwater turbidity and above water air particulate pollution. The previous version included temperature sensors and a hydrophone for recording underwater sound.

The system is designed to be simple to fit on to standard kayaks or canoes, and full instructions have been made available for anyone wishing to build their own. Sonic Kayaks are low-cost open-source systems for gathering fine-scale environmental data.
