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.

CURRENTS
The South Sub-Tropical Current predominates over the whole area of this chart, with generally west to south-westerly sets of up to a knot in rate. Sets are however variable.
In the shallower water and near the island coasts currents will be greatly influenced by the wind, and will tend to follow the trend of the coasts. For further information, see Admiralty Sailing Directions.

FISH AGGREGATING DEVICES
Mariners should exercise caution when navigating in these waters as FADs have been moored in outlying deepwater locations. The FADs are unlit: concentrations of fishing vessels may be found in their vicinity.

SATELLITE DERIVED BATHYMETRY
Refer to M_QUAL object for details of depths derived mainly from satellite imagery. Uncharted dangers may exist. For further information see Admiralty publication 'The Mariners Handbook'.
