The Ocean Observatories Initiative is a science project that was designed to deliver real time data regarding the world’s oceans, this is done through hundreds of instruments that are placed in the oceans of the world.
That data that is gathered for this project is freely available; you just need an internet connection to access it.
This program was designed to collect data for over 25 years or more, which is great because it helps measure the changes occurring in the oceans, short and long term.
This data makes it easy to better understand how the ocean is changing.
