Instant Messaging for Dolphins - Try It at Sea!
Seadragon 1.0 Beta Released ? Free (CPL)
For download and instructions:
https://leafy.dev.java.net/
Seadragon allows you to emit underwater whistles and
to acquire underwater whistles. You can now try to
communicate with many species of whales and dolphins.
Seadragon could be described as Instant Messaging for
dolphins and humans. It does not translate whistles.
It tries to recognize them, it gives a name to
unrecognized ones, and it is up to you to figure out
their meaning, if any. It allows you to emit whistles
underwater and to see the text names of whistles
emitted by cetaceans in response to yours.
This Version 1.0 Beta is for early adapters:
adventurous cetacean communication scientists or whale
watchers with a technical bent. Some free support is
provided via email.
[Editor's note: Note that in the U.S., doing something that
changes the behavior of a wild marine mammal is considered
Level B Harassment under the Marine Mammal Protection
Act. There are exceptions in some cases; for details, see
http://www.nmfs.noaa.gov/pr/laws/mmpa.htm .]
