People-Powered Science.
Make an impact while you explore.
Log animals, pollution—even zeros—in the eOceans mobile app while you're in the field. The app uses your phone’s location and time, and works offline.
Your data fuels global projects like eShark, eManta, Marine Heatwaves, and more.
We’ve done a lot together, already!
Scuba divers and snorkelers have already shared over 1.6 million observations — including 146,000 shark and ray sightings from 14,400 sites across 38 countries.
We’ve analyzed these data to guide policy, contributing to the protection of 19.2 million km² of ocean and securing protections for over 100 shark and ray species.
From the field:
Log what you see in the eOceans app!
Zeros count too.
-
Species
Log any species, with their number, health (dead, alive, injured) and behaviour. This can be used, for example, to track trends in biodiversity.
-
Social values
Log any activity that is using the space — this can be used, for example, to document the socio-economic value of these spaces.
-
Threats
Log any threats — like plastic pollution, oil spills, noise, etc. This may be used, with the Species and Social values, to examine relationships between them.
It’s easy to get started.

Every observation counts — without the risk.
Built by the scientists behind projects like the Great Fiji Shark Count, eShark Thailand with Shark Guardian, eManta, 100 Million Sharks Die Every Year, and global Shark Sanctuary Evaluations, eOceans is your all-in-one app for citizen science and research—working in real-time.
Maximum impact: Join global projects like eShark, eManta, eSeaTurtle, eJellyfish, and more—logging your sightings in real-time from anywhere in the ocean. Log once, and your observations are automatically shared with all the projects you’ve joined—no need to log more than once.
You control your data: Unlike paper logs, emails, phone hotlines, or other ‘FREE’ apps that collect and sell your data, when you log in eOceans, you own your data and decide who gets to use it—because no one wants to log a plant or animal for it to be poached by someone after.
eOceans: Built for collaboration. Built for impact. Built for you.
“We set out to help teams manage data, deliver results, and collaborate effortlessly—without the time and cost of doing it all manually. eOceans makes it happen.”
Dr. Christine Ward-Paige, CEO eOceans
