The Acousonde is a marine animal tag capable of making acoustic recordings, as
well as gathering other information. This message is forwarded; please respond

Development of the Acousonde miniature marine acoustic recorder reached two
milestones this month.
First, all planned functionality has finally been incorporated in the software operating
system. Of particular interest to the animal-tag community is the recording of
"auxiliary" channels: pressure, temperature, 3D acceleration, and 3D compass.
Others will welcome the ability to record on a timed duty cycle to extend deployment
life. The work isn't done; performance improvements remain, for example raising the
current maximum 116-kHz acoustic sample rate to 232 kHz (high-frequency channel only) and
the maximum auxiliary rate from 20 Hz to 40 Hz. But all originally-intended
functionality is now in place.
Second, we have finished designing and begun fabricating the first units of the dedicated
animal-tag "Acousonde 3B". The 3B is a complete mechanical redesign of the
Acousonde to integrate attachment and flotation with the tag, rather than requiring the
user to add them after procurement. By designing the tag, attachment and flotation
together we have made the overall package much smaller and more hydrodynamic than in the
past.
Greeneridge Sciences president Charles Greene has brought a mockup of the
Acousonde 3B to the second annual conference on the Effects of Noise on Aquatic
Life in Cork, Ireland, where Greeneridge has a booth. If you are attending as
well, please ask him to show it to you!
Best wishes,
