SARSAT - SARSAT stands for Search and Rescue Satellite Aided Tracking. It is a system of satellites operated by the governments of Canada, Russia, France and the United States. The satellites pick up distress signals from emergency radio transmitters (SEE ELT) and relay them to ground based Mission Control Centres (MCCs). The ground stations pass the information on to the nearest Rescue Coordination Centre (SEE RCC), which dispatches a rescue unit. The SARSAT system can localize a distress signal to within 30 kilometers of its source.

SAR Tech - The Search and Rescue Technicians (SAR Techs) are Non-Commissioned Officers trained in land and sea survival, parachuting, SCUBA diving, mountain climbing, helicopter rescue techniques and most importantly advanced trauma life support. Their medical training is extensive and ranks close to the level of the Advanced Life Support (ALS) paramedics of the BC Ambulance Service, although the SAR Techs tend to specialize more on trauma and less on cardiac and other injuries encountered by the ALS paramedics. The SAR Techs work in two person teams consisting of a Team Leader and a Team Member.

Schooner - Originally, a small, sharp-built vessel, with two masts and fore-and-aft rig. Sometimes it carried square topsails on one or both masts and was called a topsail schooner.

Sea Breeze - Sea breezes occur during the daytime in warm sunny weather when the air over a land area is heated more rapidly than that over an adjacent water surface. As a result, the warmer air rises and relatively cool air from the sea flows onshore to replace it. At night, the air over the land cools faster than that over the nearby ocean and causes the air circulation to be in the opposite direction - a land breeze. Land breezes are usually weaker than sea breezes and have a less noticeable effect upon the temperature."
