Near Antarctica's South Orkney Islands, researchers witnessed something not recorded in over a century: groups of more than 100 humpback whales feeding together, their blows stretching from horizon to horizon. The whaling ban is working — and the ocean is proving it.
A Century of Silence — Then This
When commercial whaling was at its peak, the waters around Antarctica's South Orkney Islands ran red. Between the 1900s and 1970s, an estimated 2 million whales were killed in the Southern Ocean — humpbacks, fin whales, blues — hunted to the edge of extinction. By the time the International Whaling Commission moratorium took effect in 1986, the seas were nearly empty.
Then the silence held. For four decades, the whales recovered — slowly, invisibly, without fanfare.
In June 2026, a team of independent scientists aboard a Sea Shepherd research vessel witnessed what none of them expected: groups of more than 100 humpback whales feeding together near the South Orkney Islands. Blows stretching from horizon to horizon. A sight not recorded in over a century.

The Ban That Worked
The commercial whaling moratorium is one of conservation's most debated success stories — contested by Japan, Norway, and Iceland, but ultimately held. Forty years later, the evidence is in the water.
Southern Ocean humpback populations have recovered significantly. Where individuals once struggled to find mates across a vast, empty ocean, they now congregate in the thousands in historically important feeding grounds.
Speed Limits for Whales
On World Ocean Day, June 8, 2026, the International Association of Antarctic Tour Operators (IAATO) announced that all member vessels must now observe a 10-knot speed limit around the South Orkney Islands.
Ship strikes are one of the leading causes of whale mortality worldwide. A whale struck at 18 knots rarely survives. At 10 knots, survivable outcomes improve dramatically. The decision came directly from the survey data — from witnessing, firsthand, what is at stake.
The Ocean's Long Memory
Humpback whales can live for 80–90 years. The individuals feeding at South Orkney today may have been calves when the moratorium began. They remember nothing of the slaughter. They know only the water, the krill, and the other whales beside them.
The recovery is real. The work is not finished.
