Marine bio-diversity
Dahab is located on the eastern shores of the Sinai peninsular in the Gulf of Aqaba, one of two
gulfs at the north of the Red Sea. Measuring 24km wide, 160km long and 1,800m at it's deepest point.
Like the rest of the Red Sea, Dahab is one of the world's premier sites for diving, rich in coral and containing a
diversity of marine wildlife.
Ancient reefs
The Gulf began 40 million years ago when a rift developed in the African continental plate and
the Arabian peninsular began to drift east. This process contines today at arate of 1-2cm per year with the rift
extending from the Dead Sea to the Great Rift Valley in Tanzania.
The Gulf of Aqaba represent the northernmost
limit for coral reefs in the Indian Ocean region. Evidence of reefs can be traced back as far as 20 million years ago,
with more recent examples seen in the surrounding exposed cliffs.
Why aluminium tanks?
Strong evaporation in this northern extension of the Red Sea creates 42% surface salinity compared
to 37% in the south, not very good for steel tanks. Hence the reason for aluminium tanks and unfortunatley, more
weight.

50m viz
With less than 60mm of rainfall per year, visibilty in most areas can range from 15m to 50m.
Fringing reefs extend only a few metres from shore and quickly drop to depths of 500m in places, ideal for
recreational and technical divers alike.
