Innovative aquaculture and marine wildlife tracking ideas awarded at the Blue-Cloud Hackathon

Blue Cloud Hackathon Winners

Over 7-9 February 2022, the Blue-Cloud Hackathon brought together nearly 150 participants from a diverse community of marine science practitioners, computer scientists and innovators to test Blue-Cloud’s web-based ecosystem of Open Science services and resources to address selected Ocean challenges. Three teams were awarded for their work towards improving aquaculture management and studying wildlife interactions.

As the Future of Seas and Oceans’ Flagship Initiative of EU HORIZON 2020 programme, Blue-Cloud is the thematic open science cloud for the marine domain. It federates services offered by marine data infrastructures, research infrastructures and e-infrastructures in Europe to support and empower Ocean research. Blue-Cloud is building a platform for collaborative Open Science offering a wealth of data, analytical tools and computing power to support researchers in developing solutions for a safe, healthy, productive, and transparent Ocean. The platform features a Data Discovery and Access Service that allows users to fetch about 10 million datasets from leading European marine data infrastructures (such as EMODnet and CMEMS) in one environment. These data and derived data products can be exploited in the Virtual Research Environment, where Virtual Labs are set to enable users to execute methods and perform collaborative research tasks.

“The Blue-Cloud platform and services have been deployed and so far tested by our project partners,” stated Dick Schaap, MARIS, Blue-Cloud Technical Coordinator, “but the next step is to confront external users and to gather their experiences and feedback on interfaces, performances, and overall understanding.”

The hackathon was a challenging opportunity to attract and engage many external users in trying out the Blue-Cloud platform and its services over a short and intensive timeframe.

“From this we got valuable feedback which definitely will help us to refine and tune the platform and its services, with a perspective of making it available and accessible for a larger community of researchers.” Schaap concluded.

Hacking the ocean with Blue-Cloud

Thanks to the Virtual Labs created as real life demonstrators in the framework of the Blue-Cloud project, participants were challenged to develop applications that contribute to improving knowledge of marine ecosystems; support the transition to a greener, blue economy; advance Ocean literacy; and/or enhance international collaboration towards achieving the Sustainable Development Goals (SDGs) of the United Nations Agenda 2030. Teams were invited to address specific challenges within three Topics and one wildcard:

  • Understanding the Ocean
  • Feeding the World
  • Predicting environmental risks
  • Wildcard: Hack the Blue-Cloud!

32 teams took part in the hackathon, featuring 149 participants from 73 countries. 27 mentors from the Blue-Cloud Consortium guided and supported participants in their journey. A total of 23 Teams completed the challenge, representing 111 participants. Amongst these 23 Teams, 10 were invited to defend their ideas during a “Pitching & Award Live Event”, as finalists.

Blue-Cloud coordinator Sara Pittonet Gaiarin (Trust-IT Services) and technical coordinator Dick Schaap (MARIS) officially kicked off the activities in an online event on 7 February, with the energetic support of the Lead of the Hackathon Coordination Team, Julia Vera Prieto (Seascape Belgium), welcoming participants and sharing the consortium’s best wishes and expectations.

Notably, and reflecting the nature and key target users of Blue-Cloud’s services, Data scientists and marine researchers made up about two thirds of the hackathon participants. There was also a considerable representation from students of both marine and computer science (about 20%), which is a promising signal for future talent and skills in support of Ocean research and the Blue Economy. The Blue-Cloud Hackathon was the first hackathon experience for almost half of the participants. Roughly one third had already attended similar events, while the rest could be considered hackathon “veterans”.

“It was very impressive to see such talent, energy and Teamwork invested in developing science-based solutions to address Ocean challenges. The results of the hackathon showcase the potential of bridging marine science and computer science to deliver innovative solutions in support of a broad range of EU and international policy objectives”, Julia Vera, Seascape Belgium added.

Inspiring solutions for open ocean science

The “Pitching & Award” event took place online on 9 February welcoming more than 130 attendees, introducing the finalist teams of the hackathon, who had the chance to present short video-pitches of their ideas developed during the hackathon. A panel of external expert judges were onboarded to evaluate the ideas and submissions of the teams, interact with participants and decide which ones deserved the 1st, 2nd and 3rd place awards. In addition, a “Blue Skies Award” was granted by popular vote.

The Particle Trackers came out on top winning the first prize with their “Sea Clearly” idea, which can help aquaculture providers, managers and end-users track pollutants such as microplastics in areas near aquaculture farms. Aquaculture was also at the core of “PerfeCt – Performance of Aquaculture under Climate change”, which was developed by the AqAdapt team and attained the second prize. The podium was closed by the Marine Wildlife Trackers, which proposed a “Wildlife Tracker for Oceans”, a real-time assessment for marine fauna habitat with phytoplankton hotspots. The Particle Trackers also received the Blue Skies Award, with 27.7% of the popular vote, while AqAdapt came in second place with 24.9%.

  • 1st Prize: The Particle Trackers – led by Delphine Lobelle (Utrecht University)
  • 2nd Prize: AqAdapt – led by Ines Haberle (Ruđer Bošković Institute)
  • 3rd Prize: Marine Wildlife Trackers – led by Bryan Vallejo (University of Helsinki)
  • Blue-Skies Award (by popular vote): The Particle Trackers

The three winning teams will be awarded funding and two dedicated coaching sessions to further develop, boost and promote the uptake of their solutions. Up to 2 members of each team will also be invited to take part in the final Blue-Cloud conference at the end of the project, with their travel costs covered.

“We are so thrilled that the Blue-Cloud will enable us to develop our idea! As early career researchers, who often work alone, we had so much fun working together from Florida to London, Bern & Utrecht! We will now define stakeholders that will benefit from our tool, while developing the code, website and phone app for wide usage.” The Particle Trackers

The hackathon was an opportunity for the Blue-Cloud consortium to see the services developed in the project “in action”, welcoming a wide and diverse community of users to test them intensively over 4 weeks.

“The hackathon set a very important milestone for the Blue-Cloud model and the sustainability of its offer. It’s the very first time for research teams external to the project to test the Blue-Cloud platform, its resources, software and datasets. The winning experiments demonstrate that open science is the way to go to achieve the objectives of the EU Green Deal and the United Nations Agenda 2030 to restore the health of our oceans and seas” Sara Pittonet Gaiarin – Blue-Cloud project coordinator

In 2022, the Blue-Cloud services will take another step forward and become available to more and more marine scientists in Europe and beyond.

Test the Data Discovery and Access Service and the Virtual Labs, become a part of the Blue-Cloud community.
