Finding Fish with
Echo-sounders
The examples used are drawings which show the boat, the sea bottom and the
fish, so that you can compare them and begin to understand how an echo-
sounder picture is made (Figure 16 is a real echo- sounder picture). In Section 10
, you ...

Manual of Offshore Surveying for Geoscientists and Engineers
The Krupp Atlas Deso 20 sounder has been in use for many years and is
probably the most popular survey echo-sounder. It has two transducers operating
on separate frequencies of 30kHz and 210kHz. The resolution of the higher
frequency ...

Whales, Dolphins, and Porpoises
They are aligned, or nearly so, at two times when the click rate of the whale is in
synchrony with the ping rate of the echo sounder. At these times the click rate is
just twice the ping rate. With each sweep of the recorder stylus two whale clicks ...

Hubert Profeta b An echo sounder trace. A sound pulse from a ship is reflected off
the seabed and returns to the ship. Transit time provides a measure of depth.

It follows from (5.29) and (5.30) that the main task for measuring depth by means
of an echo- sounder is to measure the interval At, which with small depths will be
rather small (with H=10 m. C = 1500 ms "\ At= 0.013 s) An echo-sounder works ...

higher than the threshold value, and thus, it is recorded as a seabed surface. At
the frequencies of 2 1 0 kHz and 455kHz the echo envelope of the signal
reflected from a mud and sand is above the echo sounder threshold, and thus,
the ...
