OneAquaHealth IEEE Global Hackathon
Join the OneAquaHealth IEEE Global Hackathon 2026 ! A worldwide call to innovators, creators, and problem‑solvers - the IEEE and OneAquaHealth project invite participants from across the globe to co‑create breakthrough solutions for healthier urban freshwater ecosystems. This global hackathon unites AI enthusiasts, environmental thinkers, designers, developers, researchers, and citizen‑science champions to transform real environmental and community data into tools that protect biodiversity, strengthen resilience, and improve human wellbeing. Whether you’re passionate about AI for good, urban water health, biodiversity, climate resilience, or digital innovation, this is your moment to make an impact on a global stage. Build. Collaborate. Innovate - with the world watching. Be part of a global movement shaping smarter, healthier, more sustainable cities.

Citizen Science for the Oceans: From observation to information - towards digital twins of the ocean
In this webinar you will learn about citizen science activities related to the oceans. We will use the case of jelly fish as an example, start with the observations done by citizens using mobile apps. Then you learn how the data can be integrated in systems, including the use of standards making the data, in this case biological data, interoperable. You will also learn how to approach making the apps themselves. As NextGEOSS already has citizen science data catalogued on the data hub, you will now learn how we will expand this with the help from among others Earthwatch through their contribution to the ILIAD project. This webinar aims to reach Earth observation professionals and students, Citizen science public and private organisations, App makers, ocean advocates, marine environmentalist, oceanographers, ecologists.
From the 1st of June until the 30th of September, the provinces of Barcelona, Girona, and Tarragona will participate in a Bioblitz called "BioMARató". The region that gets the most underwater observations, detects more invasive and rare species or gets the most participants will win. This event is part of the City Nature Challenge (CNC), an international friendly competition of naturalistic observations where cities worldwide will compete with each other. Participate on your own or sign up for one of the free activities on the Catalan coast (beaches in the Barcelona Metropolitan Area, Costa Daurada, and Costa Brava)
Lessons and insights from WeObserve
WeObserve tackles three key challenges that citizens observatories face: (1) awareness, (2) acceptability and (3) sustainability. Its overall mission is to create a sustainable ecosystem of citizen observatories that can systematically address these identified challenges and help move citizen science into the mainstream. As the project draws to its conclusion, team members will highlight what the project has learnt through its activities. Speakers include: Gerid Hager (IIASA) – WeObserve in a nutshell Uta Wehn (IHE Delft), Joan Maso (CREAF), Dilek Fraisl (IIASA) – WeObserve communities of practice: how to ‘do’ CoPs and some reflections Mel Woods (University of Dundee) – Accelerating the uptake of citizen observatories through MOOCs and open data challenges Joan Maso (CREAF), Valantis Tsiakos (ICCS) – Data interoperability and standardisation: using interoperability experiments and hackathons to address data-related challenges in citizen observatories The webinar will finish with a Q&A by Margaret Gold (Citizen Science Lab). The event will be in English, and you can register for free here.
Open cultural data in citizen science
This roundtable discusses the concept of citizen science as a participatory research methodology in cultural heritage and reviews good practices in creating and communicating open cultural data in citizen science initiatives. Speakers: Mariana Ziku, Fred Truyen, Susanna Anäs, Katerina Zourou, Sofie Taes
Monitoring groundwater in Limpopo Province through citizen science
On 2 March 2021 (11:00-12:00 CET), Jaqui Goldin, from the Centre for UNESCO Groundwater, will present the latest findings from a groundwater-monitoring citizen science project based in the Hout Catchment, Limpopo Province – one of the poorest provinces in South Africa. In this project, citizen scientists capture data on groundwater levels and rainfall, putting it onto a smartphone from where it is uploaded to the web. The data is then available to the Department of Water and Sanitation, and others, who are otherwise unable to access groundwater information in remote wells. After the presentation, Jaqui will answer questions about the project. Attendance is free, and the event will be held in English.
Discovering the unexplored deep marine environment
Deep underwater neutrino telescopes as KM3NeT measure neutrino and environmental events that constitute “noise” for the neutrino searches. These environmental events range from biological bioluminescence to acoustic signals from sea mammals. Citizens can support KM3NeTs scientists to increase the efficiency in the neutrino detection algorithms, providing input that will be crucial for two scientific tasks: the classification of noise types, and the identification of the frequency range and typical length of noise signals. The output of the citizen science activity will serve as a basis for training machine learning algorithms, which will automatically identify and classify the noise sources, thus monitoring the noise with an unprecedented detail. At the same time, citizens will have the opportunity to gain a greater insight of the unexplored deep marine environment. In the framework of REINFORCE, time sequences of the optical counting rates on the KM3NeT “eyes” will be made available to the general public in order to monitor ambient bioluminescence, and citizens will be invited to classify in a systematic way the various types of waveforms observed. Furthermore, in order to involve in this activity also visually-impaired citizen scientists, the “ears” of the KM3NeT neutrino telescope will also be exploited by utilising the time sequences of the acoustical signals detected. Both sound and visual data for the bioluminescence and the acoustic signals will be produced. The webinar aims to give an overview of the Deep Sea Hunters Large Scale Citizen Science demonstrator and how it will be implemented in order to engage citizens in the scientific research, showcasing the tasks that citizens will be asked to perform and how their input will be fundamental to explore the environment of the deep sea below 1000m depth in which humanity has little experience so far. Who should attend? Potential citizen scientists Neutrino researchers and academics Members of the physics and marine community You will learn: How citizens can play an active role in the advance of ground-breaking research How a deep underwater neutrino telescope works How REINFORCE demonstrator about Deep Sea Hunters will be developed How the project will work to include diverse and underrepresented groups in science Agenda 15:00 - 15:10: Welcome and introduction - Paschal Coyle, CPPM, Marseille 15:10 - 15:20: Neutrinos and KM3NeT - Gwenhael de Wasseige, APC, Paris 15:20 - 15:30: Deep Sea Hunters on Zooniverse - Remy Le Breton, APC, Paris 15:30 - 15:40: Bioluminescence - Severine Martini, Mediterranean Institute of Oceanography, Marseille 15:40 - 15:50: Submarine Intelligent Listening into KM3EnT & Abyss - Herve Glotin, Computer Science & Systems Lab., CNRS, Toulon 15:50 - 16:00: Q&A and wrap-up
