Bulgarian officers recover rare ancient amphorae destined for the National History Museum. Six intact underwater finds were handed over to the museum in October.
The collection holds one late antique jar and five Roman-era amphorae overall.
Experts believe fishing nets likely snagged sunken ships in deep offshore waters. Ancient vessels may have sunk while passing near former Dionisopolis, today Balchik.
Researchers warn mobile trawling gear damages roughly sixty percent of underwater remains. Specialists hope deep-sea archaeology will expand greatly across Bulgaria's territorial waters soon.
