Période

this thermometer was apparently in use for 25 years (Ref. 3)

Canada

Part of a large collection of meteorological instruments acquired from the Meteorological Service of Canada (previously Atmospheric Environment Service) by the CSTM since 1967. MSC is the government agency responsible for collecting and disseminating meteorological data and forecasts in Canada. It was founded in 1871 in Toronto where it is still headquartered. The MSC was originally on the University of Toronto downtown campus but moved to Downsview in 1971 on land owned by UofT. The headquarters houses laboratories, research facilities and calibration and instrument maintenance facilities (now largely contracted out).

Fonction

An instrument used to measure temperature by means of its effect on a column of mercury in glass, mounted in a sea temperature bucket for use in measuring water temperature.

Technique

An American made water temperature thermometer in a metal frame and with a rubber bumper. Surface water temperatures are measured on ships as part of the meteorological observations. Surface water temperature is an important source of energy for the atmosphere and is needed for computer forecast models. The thermometer is attached to a rope and is thrown forward along the side of the moving ship. The cup at the bottom retains some of the water so that the thermometer does not change in temperature while being raised and read (Ref. 1). This sea temperature bucket is not one of the types used by MSC in the 1950's to 1970's; those included the B.M.O. (British Meteorological Office) and D.W.D. sea water temperature buckets (Ref. 2).
