Lowest Astronomical Tide (LAT) is used as chart datum north of Utsira (an island close to Stavanger). In the southern part (between Utsira and the Swedish border) the tidal range is small and chart datum is 20 cm lower than LAT. In the inner Oslofjord chart datum is 30 cm lower than LAT.
The publication also contains information about chart datum relative to other tidal levels, return levels for extreme high and low waters and national vertical reference systems (Normalnull 1954 and Normalnull 2000).
