1992
In 1992, Sea Shepherd focused its efforts on opposing illegal commercial whaling by Norway. The day after Christmas, a Sea Shepherd crew led by Captain Paul Watson sank the illegally-operated Norwegian whaler Nybraena in the Lofoten Islands in Northern Norway.
1994
In January 1994, a Sea Shepherd crew scuttled the illegal Norwegian whaler Senet in harbor in Southern Norway.
In July of 1994, the Sea Shepherd ship Whales Forever challenged the Norwegian whaling fleet and the Norwegian government directly when Captain Watson took the ship and his crew to the Lofoten Islands to block the whaling ships. He was intercepted by the Norwegian Navy.
The Whales Forever was rammed by the Norwegian destroyer Andenes, fired upon, and had two depth charges deployed under the hull. Although suffering significant damage, the Whales Forever prevented the Norwegians from boarding and returned to the Shetland Islands having severely embarrassed the Norwegian authorities. More importantly, international media attention was brought to bear on the illegality of Norwegian whaling.
1997
In September 1997, Sea Shepherd Pacific Northwest Director Michael Kundu covertly enters Siberia with a media crew to document the killing of whales by Siberian natives. Although his life is threatened, he returns to report to the International Whaling Commission meeting in Monaco. The film crew brings back evidence of the illegal commercial whale hunt, including footage of butchered whales being processed into feed for fox fur farms. Russia continues to claim the slaughter as a "subsistence" hunt, exempt from the moratorium whaling.
1998
In 1998, the illegal Norwegian whaler Morild, owned by the most notorious whale killer in Norway - Stienar Bastesen - was sunk.
Sea Shepherd became a household name in Norway as a result.
In the fall of 1998, at the urging of the commercial whaling industries of Norway and Japan, with promises of lucrative future trade, the Makah Indian tribe claimed a right to resume whale hunting pursuant to a guarantee in their 1855 treaty with the U.S., but in contravention of subsequent international conservation law. Sea Shepherd sent two ships to Neah Bay, Washington, to protect the gray whales. They were joined on the water by a flotilla of local citizens and other anti-whaling activists. Despite mob violence, arrest, and official harassment, the coalition of activists shields the local whales and succeeds in focusing enough media attention to the hunt to make the Makah stand down without taking a single whale.
