Jonah Fisher faces icebergs on the Greenpeace ship Esperanza

The BBC's Jonah Fisher has been on the Greenpeace ship Esperanza for the past two months, tracking the Japanese whaling fleet in the Southern Ocean.

Do you have any questions about his trip?

Over the past two months the Greenpeace ship Esperanza has travelled thousands of miles chasing the Japanese whaling fleet.

They eventually caught up with a Japanese factory ship, the Nisshin Maru. Keeping this ship on the move meant the rest of the fleet were unable to kill whales for over two weeks.

The pursuit lasted for almost 5,000 miles and left the Esperanza with only enough fuel to make it back to port in Australia, leaving the Japanese fleet to continue with its mission.

As Jonah and the crew of the Esperanza make their way home they will be taking time out to answer some of your questions for the BBC News website.
