Christine monitoring the mobile base unit, tracking divers and the dive boat. The expedition is
approximately 2.8km away at the harbour breakwater, hidden from view (and radio line of sight)
by the large concrete structures that can be seen in the background (unused Mulberries from WW2).
Despite this obstruction she tracked the divers and was able to liaise with the shore based team
to give advance warning of the team returning, so that they could get hot food ready for the
returning divers, and the next dive party would be ready to go.
