Recent Developments in Canadian Tide and Water Level Measurement

The need for accurate and continuous measurement of tides and water levels in the harsh climate of most Canada´s seaboard and inland waterways presents a number of challenging problems in instrumentation. In this context, the philosophy behind our pre- sent and projected equipment needs is described, followed by a detailed discussion of some recent research and development which has resulted in a significant improvement in our capabilities of measuring tides and water levels to our stated objectives in height and time. Particular attention is paid to present efforts to automate data acquisition, recording and telemetry techniques, and to the development of instrumentation specifically for Arctic applications. The plans for future development of equipment are highlighted.
