The Web-enabled Awareness Research Network (WARN) module provides subscribers with early notifications of tsunamis and earthquakes as part of the Smart Oceans BC initiative, utilizing some infrastructure already in place for Oceans 23.0 and incorporating some new instruments. Tsunami detection uses data from pressure sensors such as the existing Bottom Pressure Recorders (BPR) and some planned coastal radar devices. Earthquake detection uses new sensors providing p-wave data. While WARN is being 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 (such as coastal radar for tsunami detection) and subscribers.

The data used by WARN is received from sensors, in real time, via the Data Acquisition module in Oceans 23.0. Pressure data for Tsunami evaluation originates from BPR sensors in the prototype. Data for earthquake assessment originates from accelerometers. Prior to analysis via WARN, the data is parsed and calibrated to pass data quality downstream for use in further analysis.
