Monitoring ocean conditions can be a pretty tricky business. In order to understand ocean dynamics, and how marine ecosystems operate, scientists need data on things like temperature, depth, and pH. Knowing these parameters over the course of time is incredibly helpful in understanding the underwater world. Due to the unique environmental challenges that ocean researchers face, and the vastness of the sea, many unknowns still exist. One research team from a Saudi university has set out to get answers using the power of fish! Bluefin™ is a wearable, stretchable, “skin-like” technology that uses silicon to "measure water temperature, pressure, depth, and pH levels in parts of the ocean where humans cannot reach," states the university website.
