Australian researchers, global environmental groups and three major shipowners are set to unveil a "new layer of vessel monitoring" that could make "going dark" a thing of the past.

The "radar harvesting" initiative is primarily aimed at fisheries management and enforcement, but more generally it would make it more difficult to hide ships.
