Noisy dredging

I was diving yesterday in Melbourne. The swells outside
the heads were heavy, so the planned dive on the Milora
did not go ahead. (Seems I'm jinxed on this wreck... On
a previous dive someone pulled the shot off the wreck so
I went down 42 metres to see sand, and bugger-all else.)
Now, on the next attempt, the trip is cancelled.)

In any case, we wound up on a wall in Lonsdale Canyon,
about 1/2 Km from the Queen of the Netherlands. The
viz was not good - 3-4 metres, at best. Not necessarily
all due to the dredging since it was an ebb going to
flood and it was rainy this week. The real problem was
the noise. At 40 metres, it sounded like we were right
next to the dredging head. It was a loud low rumbling
that sort-of vibrated right through the body. Other
divers from our boat reported a seal that was acting
really agro. Again, nothing definite to pin it on the
dredging, but seals are generally playful, not agro. And,
if it was me dealing with the noise all the time, I
can imagine that I might not be all that cheerful.

Saw an odd fish that looked a lot like a Centropogon
australis, but with a redish tint to the scales. He
was hiding under a ledge and well back. Too bad the
camera was on the boat -- left there since the conditions
didn't look favourable for photography.

Looking at diving the Euro next Saturday.
