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.

CAUTION - NAVIGATIONAL AIDS
Only the principal lights and radio navigational aids, indicated by symbols and names are shown on this chart.

DOUBTFUL DATA
Reported but unconfirmed depths or dangers are indicated by an encircling dotted line.

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.

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 BASES
Manned bases are indicated by a small circle, o, with name and / or country abbreviation; unoccupied bases and refuges are indicated by a small ∆. These are correct to 1993. For further information see Admiralty Sailing Directions.

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 scheme which covers the area of Antarctic Treaty jurisdiction, defined as south of 60°S. Antarctic territorial claims are not depicted on this chart. The Producer Nation has rendered all names in accordance with its own national toponymic policy and these do not necessarily reflect the policies of the other nations.
