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.

DEPTH CONTOURS
The depth contours on this chart have been interpolated from all available information, which in ocean areas is insufficient for an accurate portrayal of the sea bottom. Vessels should navigate with due caution inside the 200 metre contour as uncharted dangers may exist.

MAGNETIC VARIATION CURVES ARE FOR 1995
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.

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

ANTARCTIC TREATY REGULATED AREA
For details of locations within the limits of this chart to which certain Antarctic Treaty restrictions and regulations apply, see Admiralty Sailing Directions.

This chart is produced under the auspices of the International Hydrographic Organisation and is part of a cartographic scheme which covers the area of application of the Antarctic Treaty. Claims to territorial sovereignty, addressed by Article IV of the Antarctic Treaty, are not depicted on this chart. The Producer Nation has rendered all names in accordance with its own national toponymic practice, and with IHO Specifications and Regulations for International (INT) Charts, and this does not necessarily reflect the practice of other Nations.
