The WARN module within Oceans 2.0 provides subscribers with early notifications of tsunamis and earthquakes as part of the Ocean Networks Canada's () Smart Oceans BC initiative. It utilizes existing the Oceans 2.0 data acquisition infrastructure while incorporating some new instruments and new event detection algorithms and software. Tsunami detection uses data from pressure sensors such as the existing Bottom Pressure Recorders (BPR) for far-field tsunamis and a planned coastal radar system for near-field events. Earthquake detection uses new sensors providing p-wave data that were deployed in late 2014 but will be upgraded in early 2015 with more sensitive instruments. While WARN was implemented as a research/prototype with limited sensors and select early adopters for now, it is being designed to be expandable to greater numbers and types of instruments and subscribers.
