There was a stretch yesterday (within the past 16 hours) when neither Ocean Shield nor Echo were in the "box". Perhaps they were standing off while one of those which do not say where they are going nor where they have been was having a listen.
More likely standing off while they dropped the sonobuoys. Wouldn't want to get tangled up in the 1000 foot cables suspending the hydrophones.

Reason: 1000 feet not 1000 meters cable length - analysis software was modified, not sonobuoys
