Due to human impact and the rise in climate change, coral reefs and the health of its inhabitants are in a dire situation. Reef Support aims to aid this situation and bring relief to an already hurt ecosystem.
The objective of this challenge is to use machine learning to identify the type of coral in an image and whether it is healthy or not.
Your solutions will be used by the Ocean Hackathon.
About the Ocean Hackathon® Cape Town:
For the first time since the creation of the Ocean Hackathon® in 2015, an African city is on the world map of the 15 cities competing simultaneously to solve challenges faced by the oceans, using essentially data.
Ocean Hackathon® Cape Town will take place as part of this year’s Ocean Innovation Africa event. The African chapter of the Ocean Hackathon® will take place over 48 hours straight from the 5th to the 7th of November 2021, at the V&A Waterfront, with data scientists, project managers, web developers, marine scientists and communication specialists forming 9 teams of up to 6 hackers.
Supported by data scientists and coaches, the teams will have to tackle one of the 3 selected ocean-impact data challenges:
The participants will stand a chance to win one of the cash prizes and to represent Cape Town at Ocean Hackathon® Grand Final, in France, in December 2021.

Presentation of challenges:
We invite you all to consider volunteering as a coach/mentor. The coaches give guidance to the teams on subjects such as:
The coaches are not assigned to a specific team. However, duos of coaches will be designated to follow each team during the Hackathon and liaise with other coaches in person or online.
The coaches do not necessarily have to be available throughout the whole event. A programme of attendance will be established and the schedule will be communicated to the participants. The coaches who have the same expertise will take turns during the event.
The coaches can provide tutorials and best practices documents to help the teams.
The highlights for the local coaches during the event are:
- Briefing meeting on 5th November afternoon
- Meeting on 6th November afternoon to exchange about the projects
- Meeting on 7th November afternoon to brief the jury before the teams pitch their projects
The coaches will be also asked to evaluate the projects on:
About Reef Support (reef.support)
Reef support is a Dutch start-up that focuses on building software to accelerate the transition from data to decisions to protect coral reefs. Their mission is to take practical action and support the blue economy with imagery and artificial intelligence. They aim to accomplish it by building robust research and predictive maintenance tools for research institutions, reef managers and other coastal activities – from small conservation efforts to large-scale coastal developments.
About Ocean Innovation Africa (ocean-innovation.africa)
Africa offers a particularly high potential in terms of Blue Economy developments, paving the way to ocean community-based resource management and offering an ideal ground to test and scale impact innovation. Africa's ocean economy – three times the size of its landmass – is on top of the continent's political agenda and seen to be a major contributor to continental transformation and growth of industries such as fisheries and aquaculture, marine renewables and biotechnologies, boat building and shipping, coastal tourism and ocean-sports, etc.
The development of the Blue Economy is an immensely important first step towards creating Sustainable Development pathways and this is what Ocean Innovation Africa event (OIA) promotes. The platform showcases African initiatives and brings together entrepreneurs, investors, scientists, businesses and leaders that are working from around the world towards the development of a more sustainable ocean economy.
Ocean Innovation Africa Summit 2021 (ocean-innovation.africa/the-event)
We believe that innovations led by science, technology, and entrepreneurship will provide the necessary leverage points to address the Sustainable Development Goals (SDG), at the right pace and scale. By addressing the issues of sustainable Oceans economy and Oceans conservation, our event seeks to find solutions linking up to almost all SDGs in addition to SDG14 – Life Below Water.
Our focus stems from a passion and the need for efficient, impactful action: at the current pace, SDGs objectives would only be met by 2094 instead of 2030! Oceans are the heart and lungs of our planet, it is crucial – and now urgent – to support the development and adoption of new sustainable ocean solutions that will shape better interactions between people and the Earth’s largest ecosystem. In the recovery of the recent COVID-19-related crisis, Oceans have also a key role to play by keeping trade moving between nations and providing sustainable energy and healthy food for all.
Teams and collaboration
You may participate in competitions as an individual or in a team of up to four people. When creating a team, the team must have a total submission count less than or equal to the maximum allowable submissions as of the formation date. A team will be allowed the maximum number of submissions for the competition, minus the total number of submissions among team members at team formation. Prizes are transferred only to the individual players or to the team leader.
Multiple accounts per user are not permitted, and neither is collaboration or membership across multiple teams. Individuals and their submissions originating from multiple accounts will be immediately disqualified from the platform.
Code must not be shared privately outside of a team. Any code that is shared, must be made available to all competition participants through the platform. (i.e. on the discussion boards).
The Zindi user who sets up a team is the default Team Leader. The Team Leader can invite other data scientists to their team. Invited data scientists can accept or reject invitations. Until a second data scientist accepts an invitation to join a team, the data scientist who initiated a team remains an individual on the leaderboard. No additional members may be added to teams within the final 5 days of the competition or the last hour of a hackathon, unless otherwise stated in the competition rules
A team can be disbanded if it has not yet made a submission. Once a submission is made individual members cannot leave the team.
All members in the team receive points associated with their ranking in the competition and there is no split or division of the points between team members.
Datasets and packages
The solution must use publicly-available, open-source packages only.
You may use only the datasets provided for this competition. Automated machine learning tools such as automl are not permitted.
If the challenge is a computer vision challenge, image metadata (Image size, aspect ratio, pixel count, etc) may not be used in your submission.
You may use pretrained models as long as they are openly available to everyone.
The data used in this competition is the sole property of Zindi and the competition host. You may not transmit, duplicate, publish, redistribute or otherwise provide or make available any competition data to any party not participating in the Competition (this includes uploading the data to any public site such as Kaggle or GitHub). You may upload, store and work with the data on any cloud platform such as Google Colab, AWS or similar, as long as 1) the data remains private and 2) doing so does not contravene Zindi’s rules of use.
You must notify Zindi immediately upon learning of any unauthorised transmission of or unauthorised access to the competition data, and work with Zindi to rectify any unauthorised transmission or access.
Your solution must not infringe the rights of any third party and you must be legally entitled to assign ownership of all rights of copyright in and to the winning solution code to Zindi.
Submissions and winning
You may make a maximum of 10 submissions per day.
You may make a maximum of 50 submissions for this competition.
Before the end of the competition you need to choose 2 submissions to be judged on for the private leaderboard. If you do not make a selection your 2 best public leaderboard submissions will be used to score on the private leaderboard.
Zindi maintains a public leaderboard and a private leaderboard for each competition. The Public Leaderboard includes approximately 20% of the test dataset. While the competition is open, the Public Leaderboard will rank the submitted solutions by the accuracy score they achieve. Upon close of the competition, the Private Leaderboard, which covers the other 80% of the test dataset, will be made public and will constitute the final ranking for the competition.
Note that to count, your submission must first pass processing. If your submission fails during the processing step, it will not be counted and not receive a score; nor will it count against your daily submission limit. If you encounter problems with your submission file, your best course of action is to ask for advice on the Competition’s discussion forum.
If you are in the top 20 at the time the leaderboard closes, we will email you to request your code. On receipt of email, you will have 48 hours to respond and submit your code following the submission guidelines detailed below. Failure to respond will result in disqualification.
If your solution places 1st, 2nd, or 3rd in the final ranking, will NOT be required to assign rights of copyright to Zindi. We will however encourage the winners to share their code on GitHub as a public good to the sector.
If two solutions earn identical scores on the leaderboard, the tiebreaker will be the date and time in which the submission was made (the earlier solution will win).
If the error metric requires probabilities to be submitted, do not set thresholds (or round your probabilities) to improve your place on the leaderboard. In order to ensure that the client receives the best solution Zindi will need the raw probabilities. This will allow the clients to set thresholds to their own needs.
The winners will be paid via bank transfer, PayPal, or other international money transfer platform. International transfer fees will be deducted from the total prize amount, unless the prize money is under $500, in which case the international transfer fees will be covered by Zindi. In all cases, the winners are responsible for any other fees applied by their own bank or other institution for receiving the prize money. All taxes imposed on prizes are the sole responsibility of the winners. The top 3 winners or team leaders will be required to present Zindi with proof of identification, proof of residence and a letter from your bank confirming your banking details.Winners will be paid in USD or the currency of the competition. If your account cannot receive US Dollars or the currency of the competition then your bank will need to provide proof of this and Zindi will try to accommodate this.
Payment will be made after code review and an introductory call with the host.
