The project
pHil is the outcome of our participation in the Costal data gap challenge. This challenge was implemented together with Ocean Data Factory Sweden (ODF) and Ocean Tech Hub Lda and was executed through the course Leading in a digital world (TEK765). The course is held at Chalmers Technological University of Gothenburg and is one of the courses of the Industrial Economics and Engineering bachelor. The examination of TEK765 usually varies and this year it took the shape of the development of a sensor and the analysis of the matching industry and stakeholder. Through Leading in a digital world and the Coastal Data Gap Challenge we, and the rest of the second year students of Industrial economics and engineering, got to learn about how to lead in a digital world at the same time as we got the chance to tackle our marine-related challenges.
This website is the result of our work with the Coastal Data Gap Challenge. Here you can find all the information you need about coastal data gaps, citizen science and the oceans but especially you can learn more about the industry of diving, how divers can contribute to these problems and how the future of diving will be influenced by new innovations, technology and AI. With the help of the course content and the frameworks we’ve learnt about we’ve been able to do analyses such as PESTEL and scenario matrix.

Presentation
Welcome to the pHil presentation, where we dive deep into the capabilities of our pH sensor. Learn how pHil delivers precise and accurate pH readings, providing you with reliable data for scientific analysis. Join us in this presentation to discover the potential of pHil and elevate your pH measurement capabilities.
Slide 1
Slide 3. Therefore we are creating an opportunity to make a difference
Slide 5: This is pHil: a pH-meter meant to be used by citizen scientists to help fill Oceans Data Gaps and gather pH-data. This is how it works: Our sensor uses a low cost pH-instrument and a raspberry pi computer but is mainly made from accessible material such as standard tubes and simple electronics. The total cost for pHil will be about 1200 swedish crowns.
Sllide 2: The world's oceans are changing. The consequences of human behavior can be seen both above but also beneath the surface. In order for us to understand these changes we need to understand our oceans and for that we need data.
Slide 4. An opportunity we call pHil:
Slide 6: Having all the required building- and coding-guides available on our website makes it possible for anyone, anywhere to make their own pHill and contribute with data.
Slide 7: The data will be accessible on our webpage, showing a graph of the pH and its location, but could be downloaded in its raw format.
Slide 9: pHils main users will be divers. Since they experience the consequences of a decreasing pH level in our ocean first hand and after talking to several divers it’s clear they are more eager to preserve and improve the state of our oceans. By using pHil the scope of their dive will widen from just being an adventure to also helping preserve the wellbeing of the oceans and the future of diving.
Slide 11: Today divers use many different gadgets and sensors and there is already a routine of logging every dive and making the details available for other divers. Therefore the step to also bring pHil to dive won't be too far since it will be easily integrated with their existing equipment and customs. The sensor is designed so that it won’t jeopardize neither the safety nor the quality of the dive and the diver could either choose to strap the sensor to the diving tubes or leave it stationary by the boat. Using pHil will be a natural next step without demanding too much of the divers, reassuring them to contribute with citizen science.
Slide 8: But why is pH-data needed? We chose to measure pH since it is one of the largest data gaps we have in the oceans. Few people know about the fact that pH varies a lot in coastal areas, both daily and seasonally. This is largely caused by biological activity, but the true extent of these variations are not thoroughly understood. It is vital that we map the present in order to understand the future. If we lose control of the acidity variations their peaks and valleys could become so extreme that organsims comes to harm and the consequences could be a large loss of biodiversity.
Slide 10: However we will not be focusing on the individual diver but the diving community. A majority of all dives occur in groups and by targeting these diving clubs and associations we can lower the threshold for the individual to use the sensor. Our goal is to make pHil a given part of the diving-routine and that every new diver will learn from their first dive to pHil the data gaps.
Slide 12: So join us in our mission to collect data. Help us pHil the gap!
