Mike,
I have a mix of practical, theoretical and scientific knowledge on this
subject, but would not consider myself a leading expert. Judging from the
questions that you listed and the proposed rough-science experiment (I have
performed such experiments and the associated modeling and analyses), I can
probably provide some or most of what BBC would want. There are few
open-literature publications covering this subject, but I happen to have
some of them, and BBC might appreciate these for citation purposes.

Subject: LF: Submarine comms
I have received the following from the BBC. Does any member of this group
have direct practical or theoretical knowledge of VLF submarine comms and
would be able to help? Please reply direct to me at:
mike.dennison =at= ntlworld.com
"BBC Coast is making a short film about submarines.
"As part of the piece we would like to explain how communications worked.
How were messages sent from shore to the submarine?
"I know you specialise in low frequencies, and I´d very much like to have
a chat with you about the principles involved in undersea comms.
Specifically about VLF ( very low frequency) transmissions.
"We also hope to set up a `rough science´ experiment which would help
explain how/ why VLF is able to penetrate water.
"Unfortunately we are up against a tight deadline, and need to film the item
during the first week of December."
Thanks
MIke, G3XDV
