Sea state (SS) is a widely used characterization of ocean wave activity: the larger the waves in an area over a period of time, the higher its SS. While some activities, such as submarine evasion, may benefit from large waves, high SS can slow warship transits, disrupt search and rescue (SAR) activities, or add danger to routine activities like operating a maritime helicopter at sea. The aim of this report is twofold. First, it reviews a 30-year time series of wave data to give the Royal Canadian Navy (RCN) an assessment of the waves and SS found within the Canadian search and rescue regions (SRRs). Second, it examines the probability of SS along key RCN transits that extend beyond the Canadian SRRs. Results presented herein may provide insights for the structural design requirements of future warships, for planning warship transits so as to reduce the chance of encountering unwanted sea states, and for planning for any other SS-impacted events, such as number of SAR events and their distribution.
