Crowdsourced app for jellyfish warnings

JellyOh gathers geolocation data on jellyfish sightings and notifies users in nearby beaches.

We’ve seen geotagged sharks sending tweets when they approach popular beaches in Australia, and now Israel-based JellyOh is aiming to provide a similar warning system for jellyfish.

Because jellyfish appear in such large numbers and cannot be physically tagged, JellyOh uses a crowdsourced app with geolocation data, so that users can tag where they’ve sighted a jellyfish. Anyone else using the app will then be notified that jellyfish are present in their vicinity.

JellyOh uses a similar approach to apps that crowdsource researchable data, like the mosquito-tracking app we wrote about previously. What other useful geolocation information can be crowdsourced?
