Hydrometeorological data collection system for Lake Ontario

As part of the International Field Year Great Lakes (IFYGL), a data collection system consisting of a network of 21 hydrological and meteorologicalmeasurement stations for both offshore and land installation at Lake Ontario has been developed for the U. S. Lake Survey. Five interrogation stations monitor the measurement stations by VHF telemetry or hardwire connection as required. A control center in Rochester accepts the data from the interrogation stations via phone line every six minutes. There the data is combined, recorded and sent via phone line to the project´s computer center in Detroit. The system will be used by the U. S. Lake Survey to acquire pertinent data throughout 1972. At the same time, the Canadian government will acquire similar data from the opposite side of the lake.
