Navy has published a supplemental Environmental Impact Statement (SEIS) for its
use of SURTASS LFA sonar, available for review at
comments on the SEIS are due February 10, 2006.

The Navy proposes to employ SURTASS LFA sonar
within the same operational areas as proposed in its original EIS published

is LFAS? LFAS is an acronym for a Navy project, otherwise known as Low Frequency
This project is aimed at detecting the presence of submarines using low
frequency sounds. The reasoning behind using low frequency sounds is
that those sounds travel great distances.
- LFAS is often related to
which is developing a system which will generate pressure pulses of
energy with timed explosions to neutralize the threat of mines. The only
similarity is that both projects will introduce more noise into the

- Given the heated debates between
the researchers and the conservationists, there are several political
- Why should such a system be
developed? Doesn't the country already have adequate measures to protect
- The technology used in the
LFAS project is not a new idea. The concept of using sound for
underwater detection has been around for years.
- The whales are definitely a
part of this earth like the rest of us and should be treated with equal
