  Over several days in early August 2021, while at sea in Chatham Strait,
Southeast Alaska, aboard M/Y Blue Pearl, an online twitch.tv stream broadcast
in real-time humpback whale vocalizations monitored via hydrophone. Dozens on
mainland North American and around the planet listened in and chatted via the
stream. The webcasts demonstrated a proof-of-concept: only relatively
inexpensive commercial-off-the-shelf equipment is required for remote mobile
streaming at sea. These notes document what was required and make
recommendations for higher-quality and larger-scale deployments. One conclusion
is that real-time, automated audio documenting whale acoustic behavior is
readily accessible and, using the cloud, it can be directly integrated into
behavioral databases -- information sources that now often focus exclusively on
nonreal-time visual-sighting narrative reports and photography.
