Siddarth Chakravarty of India is the captain of the Sea Shepherd vessel M/V Sam Simon. Sid was a merchant marine, and left that profession to participate in full-time marine conservation. He has been on multiple Sea Shepherd Antarctic campaigns to save whales from the formidable Japanese whaling fleet. In the OCEAN WARRIORS series, he teams up with Captain Peter Hammarstedt to chase the illegal trawler the Thunder for months. His crew collected miles of illegal gill nets and other evidence, working with Interpol to strengthen the case against the Thunder. Their tireless work on this mission resulted in an historic conviction.
