✦ Synopsis

Considerable rock construction and tunnelling activity takes place in Norway, annually exacavates approximately 100 km of tunnels. The paper describes two tunnelling milestones in sub-sea tunnelling that were achieved in 1998:1) excavation of a large sub-sea chamber with only 15 m to the sea bottom at 55 m water depth; and 2) dry piercing to the sea bottom and pull-in of a pipeline without use of divers.

A large turbidity current was detected in the Zaire submarine valley at 4000 m water depth. Current meters, turbidimeter and sediment trap deployed on a mooring located in the channel axis, although they were damaged, recorded the signature of a very high energy event.
