Introduction

The purpose of this project was to install a permanent tide gauge at Cape Roberts. In November 1988 a tide gauge pressure transducer was installed at Cape Roberts within a steel pipe bolted to the coastal rock. This installation was subsequently lost when the coastal ice foot broke off in February 1989. The transducer site we had choosen was the best available because it had deep freely circulating water under the ice foot close to shore but it was clear that a permanent installation required greater protection. I believed this could be achieved by installing the transducer in a hole drilled at an angle through the rock to exit into free water beneath the ice foot.
