Cape Roberts Tide Gauge

Cape Roberts Tide Gauge

Land Information New Zealand

A tide gauge was installed at Cape Roberts in November 1990 and has been in near continuous operation since. Each year the rise and fall of the sea ice is observed over a 2 - 3 day period during a spring tide, using GPS. These measurements are related to a tide gauge benchmark and the sea surface to enable the reliability of the tide gauge to be checked. The tide gauge data is archived by Land Information New Zealand (LINZ). The operation of the tide gauge has encouraged USGS and Ohio State University workers to establish Cape Roberts as a primary datum for their GPS stress and deformation control network in south Victoria Land. In 2000 LINZ in partnership with USGS established a continuously recording GPS station at Cape Roberts.
