Vladimir Putin takes trip in mini submarine
Russian President Vladimir Putin took a trip on a small submersible 60 metres (200 feet) to the bottom of the Gulf of Finland to see the remains of naval frigate Oleg, which sank in 1869.
The remains, being examined by marine archaeologists, lie off the island of Gogland 180 kilometres (110 miles) west of St. Petersburg.
Putin has become well known for his adventurous stunts.
Previous adventures have included; a trip to the bottom of Lake Baikal, the world's deepest lake, flying with his hang glider with rare cranes, a scuba dive in which he brought up pottery shards that his spokesman later admitted had been planted and his famous bare-chested horse riding in Siberia.
