Hydrography
48. The Royal Navy's survey vessels have continued their surveying
and charting operations, providing essential navigational information
both for defence purposes and for commercial shipping interests.
Agreements have been reached with the French and Dutch Hydrographers
areas of surveying responsibilities to avoid duplication of
effort. In April 197 survey vessels of the Royal Navy began a
comprehensive and systematic geophysical survey of virtually the

Department of Energy. This will provide the Government with informe-

resources.
