A healthy ocean is essential to a healthy planet. But our oceans are currently in the midst of a silent crisis. Rising levels of carbon are causing quiet, but catastrophic, changes in our oceans’ chemistry, which can only lead to our waters becoming unsustainable for the coral reefs and sea life that we depend upon for our very own survival. Monitoring and understanding this troubling problem is critical to solving it, but pH sensory technology that can affordably, accurately, and efficiently measure at the deepest depths does not yet exist.
