Scott Base Tide Gauge

Scott Base Tide Gauge

NIWA

A sea level recorder and barometer was installed at Scott Base in January 2001 initially to support oceanographic and hazards research (including tsunami) and to support hydrographic surveying. Sea level and atmospheric pressure and temperature are recorded at 5-minute intervals and stored every 24 hours. The tide gauge data is archived by NIWA. Data are retrieved daily by NIWA and processed for storm surge before being uploaded to a web site. 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.
