have better images of Mars and Venus than of two-thirds of our own planet! In view of the fact
that Britain is a maritime nation, and the sea has had such a massive influence on us, it's an
absolute scandal that we know so little about the area just off our shores!'
Once bathymetric techniques have identified sites where people might have built their homes
and villages, divers could be sent down to investigate further. The idea of Britain as a natural
island kingdom will be challenged by these findings: Britain has been inhabited for about 500,000
years, and for much of this time it has been linked on and off to continental Europe. It remains to
be seen how far this new awareness is taken on board among our 'island' people.
In fact, the use of bathymetry scanners will not be limited to the study of lost landscapes and
ancient settlements. It will also be vital in finding shipwrecks. Records show that there are about
44,000 shipwrecks off the shores of Britain, but there is good reason to believe that the real figure
is much higher. In addition, commercial applications are a real possibility. Aggregates for the
construction industry are becoming increasingly expensive, and bathymetry scanners could be
used to identify suitable sites for quarrying this material. However, mapping the sea bed will also
identify places where rare plants and shellfish have their homes. Government legislation may
prevent digging at such sites, either to extract material for a profit or to make the water deeper:
there are plans to dredge parts of the English Channel to provide deeper waterways for massive
container ships.
