Alphabet's X launches Tidal to automatically track and log fish behavior

Alphabet's R&D subsidiary X has unveiled its next "moonshot project," as the company strives to improve ocean health through automatically tracking and logging the behavior of fish over time. The oceans constitute more than 70% of Earth's surface, and play a pivotal part in regulating the global climate. They also provides billions of people with food, with fish generally having a lower carbon footprint relative to land-based animals. But understanding what's going on underneath the oceans is key to protecting it, which is what Google's sister company is now setting out to achieve. Tidal, as the new project is called, is setting out to help preserve the ocean's ability to "support life and help feed humanity, sustainably," noted Tidal project lead Neil Davé, in a blog post.
