Dear Roy

Do you know of any researchers who may be able to help me with the
following questions?

Regards

Don

A very tricky question:

I am seeking any information, or directions to where such info. may be
obtained, on the possible effects of an underwater DC transmission line on
skarks & other marine animals for the Tasmanian Fishing Industry Council

The line in question is a proposed underwater main conductor between
Tasmania and mainland Australia. the line is rated at 480 MW, with a
maximum short-term rating of 600MW.  It is  a DC line  which will be
located just under the loose sediments on the bottom of the Bass Strait. An
ground electrode (anode) will also  be used which will be buried in the sea
bed on each side of the strait so the earth is part of the circuit.

Questions:

1) The proponents claim that there would be no electric field but would
this necessarly be the case? There would obviously be a magnetic field.

For the Olympics ocean swimming events  divers are swimming with an
electric device designed to repel  sharks. It is well known that skarks are
very sensitive to electric fields but I do not know about magnetic fields.

The fishing council was concerned about the possibility of an undersea
electric field coming from this cable/anode acting as a 'fence' to stop
migrations for sharks & other marine animals moving along the botton?

Any assistence, especially contacts with suitable marine researchers would
be greatly appreciated.

Sincerely

Don Maisch
