Historical observations of sea level at Port Arthur, Tasmania
Contains observations of sea level at Port Arthur, Tasmania during the period 1840 to 1842.
A sea level benchmark was struck on a small cliff on the Isle of the Dead, near Port Arthur, Tasmania by T.J. Lempriere and Captain Clark Ross. Lempriere had previously constructed a tide gauge at Port Arthur where he made observations of the times and heights at approximately high and low water from mid-1837 to at least the end of 1842.
No detailed information about the construction of the tidal gauge appears to have survived and was probably not self recording.
Data includes the date, time and sea level.
