CGS Petrel
CGS Petrel was a small Canadian Government Ship that patrolled the upper Great Lakes, from 1892 to 1904. Her main duties included fishery patrol. On August 12, 1903, the Petrel fired upon an American fishing vessel, Silver Spray, that appeared to be fishing in Canadian waters, off Long Point, in Lake Erie. A number of shots hit Silver Spray, and one American crew member was injured. The American Silver Spray evaded capture. Her captain would later claim she wasn't fishing in Canadian waters, that some of her nets had come adrift, and had drifted into Canadian waters.
The incident is said to have triggered Canada and the USA signing the Boundary Waters Treaty of 1909.

Centimetre–gram–second system of units
The centimetre–gram–second system of units (abbreviated CGS or cgs) is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways of extending the CGS system to cover electromagnetism.
The CGS system has been largely supplanted by the MKS system based on the metre, kilogram, and second, which was in turn extended and replaced by the International System of Units (SI). In many fields of science and engineering, SI is the only system of units in use but there remain certain subfields where CGS is prevalent.
In measurements of purely mechanical systems (involving units of length, mass, force, energy, pressure, and so on), the differences between CGS and SI are straightforward and rather trivial; the unit-conversion factors are all powers of 10 as 100 cm = 1 m and 1000 g = 1 kg. For example, the CGS unit of force is the dyne which is defined as 1 g·cm/s2, so the SI unit of force, the newton (1 kg·m/s2), is equal to 100,000 dynes.
Goose Lake Aerodrome
Goose Lake Aerodrome (TC LID: CGS2) is a privately owned aerodrome with an all weather gravel and two seasonal ice runways located on Goose Lake, Nunavut, Canada. The ice runways are, subject to operator maintenance, open from January to April, and, along with the land based gravel runway, service the related explorations for gold as part of the Back River Gold Project.

CGS-9896
CGS-9896 is an anxiolytic drug used in scientific research. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.
CGS-9896 is a benzodiazepine receptor partial agonist, which produces long-lasting anxiolytic and anticonvulsant effects in animal studies, but does not produce sedative effects. It also increases appetite, and reduces the development of gastrointestinal ulcers following chronic stress.
