SATELLITE DERIVED POSITIONS
Positions obtained from satellite navigation systems referred to WGS 84 Datum can be plotted directly onto this chart.  Caution must be exercised in the transfer of geographical positions to other charts not in terms of WGS 84 Datum.

TIDAL LEVELS
The tide regime at Scott Base is diurnal. Every two weeks there is minimal fluctuation in water level during the period when neap tides are experienced.

ANTARCTIC TREATY AREA
Mariners navigating in this area should be aware that regulations apply to such activity in the Antarctic Treaty Area. For more information contact the Antarctic Policy Unit at the Ministry of Foreign Affairs and Trade.

CAUTION
