Ever wonder where humpback whales spend their winters? The Hawaiian Islands Humpback Whale National Marine Sanctuary is a special place. It protects these amazing creatures. We stand at the edge of this sanctuary.
This sanctuary is one of the world’s most important whale habitats. Thousands of humpbacks migrate here each winter. They come to breed and nurse their young. Imagine these gentle giants traveling thousands of miles. They journey from Alaska to these warm waters.
The Hawaiian Islands Humpback Whale National Marine Sanctuary was designated in 1992. The United States Congress created it. Its goal is to protect the endangered North Pacific humpback whale. It also protects their habitat. The sanctuary promotes research and education. Long-term monitoring is also a key part.
The sanctuary covers 1400 square miles. That is over 3600 square kilometers of ocean. It includes waters from the shoreline to 600 feet deep. This area includes seagrass beds and coral reefs. Over 25% of Hawaii’s reef animals are unique. They are found nowhere else on Earth.
This sanctuary is unique. It focuses on a single species. It relies on other agencies for enforcement. There are few protective rules specific to the sanctuary.
In the past, some worried a marine sanctuary would restrict fishing. Hawaii’s Governor even paused its consideration. Later, Congress directed NOAA to study the idea again. Public meetings shaped the sanctuary’s boundaries. A Sanctuary Advisory Council was created.
The sanctuary mainly uses existing protections. These deal with approach and harassment of whales. They also cover waste discharge. Boaters can get permits to discharge waste.
Humpback whales are the stars here. Almost two-thirds of North Pacific humpbacks come to Hawaii. Estimates range from 4000 to 10000 whales. They come to breed and nurse. They don’t eat here. Their throats are too small. In Alaska, they eat krill. They travel 3000 miles in under two months.
Whaling once decimated their numbers. In 1966, the International Whaling Commission protected them. Illegal whaling continued into the 1970s. Now, there are about 30000 to 40000 humpbacks worldwide.
Humpbacks have very long flippers. They can be 30% of their body length. They can reach 55 feet long. They weigh about one ton per square foot. Their white fluke markings are unique. Scientists use them to identify individual whales.
Calves are born 10 to 15 feet long. They drink their mother’s milk. Sometimes dolphins follow mothers and calves. They may eat leftover milk.
Scientists speculate about breaching. It could be to knock off barnacles. It could be a show of dominance. Males compete in “competition pods”. They fight for the chance to escort a female.
Male humpbacks sing songs. Whales in the same area sing the same song. The song changes slightly each year. These behaviors can be seen from shore.
Native Hawaiians have a close relationship with the ocean. Sanctuary waters are used for recreation. Whale watching is popular. The sanctuary aims to minimize impact on whales. Whale watching supports jobs and revenue in Hawaii.
The Hawaiian Islands Humpback Whale National Marine Sanctuary protects these whales. It ensures these magnificent creatures thrive for generations to come. The whales continue to sing their songs in Hawaiian waters.
