Deploying and maintaining the Internet-connected ocean is a complex and ambitious undertaking. For starters, water and electronics do not play well together and the crushing deep sea pressure makes it impossible for humans to survive at depths below ~100 metres without a submersible. Then factor in wind, weather, currents, tides, the technical challenges of innovative ocean observing infrastructure, and seasonal access. Despite all this, ONC has been successfully bringing continuous real-time ocean data to the surface since 2006.
