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.

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.

CURRENTS AND ICE
For further information on ocean currents and ice in the area of this chart, see Admiralty Sailing Directions and Routeing Charts.

MAGNETIC VARIATION CURVES ARE FOR 2000
The Magnetic Variation is shown in degrees, followed by the letter E or W as appropriate, at certain positions on the curves. The annual change is expressed in minutes with the letter E or W and is given in brackets, immediately following the variation. Approaching the South Magnetic Pole the annual change to the magnetic variation is large (generally greater than 30' E or W as applicable) and increases rapidly towards the pole. 

SURVEYED AREA
A hydrographic survey has been conducted in this area. Some coverage limits may have been omitted for clarity. 

CAUTION
Mariners should proceed with extreme caution as unidentified hazards may exist.
