ATOLL DEPTHS

The depiction of reefs and dangers within the atoll is based chiefly
on satellite imagery and aerial photography. Depths within the atoll
are taken partly from old leadline surveys and miscellaneous lines of
soundings. Mariners are advised to navigate with particular caution
as charted shoals may be out of position and uncharted shoals and
patches of coral may exist. In addition, many of these shoals are
visible on aerial photography but their extent below water is
unknown. For further details see the source diagram and the
Mariner's Handbook which gives guidance on the interpretation
of source data.
