Whale
The IWC has designated two whale sanctuaries: the Southern Ocean Whale Sanctuary, and the Indian Ocean Whale Sanctuary. The Southern Ocean whale sanctuary spans and envelopes Antarctica. The Indian Ocean whale sanctuary takes up all of the Indian Ocean south of 55°S. The IWC is a voluntary organization, with no treaty. Any nation may leave as they wish; the IWC cannot enforce any law it makes.
Whale watching
In the past this area was the US whaling industry's capital, particularly Nantucket, an island just off the coast of Massachusetts. Though strict laws prohibit molestation of these large wild mammals, it is not unknown for the whales to approach whale watching boats uninvited, particularly curious calves and juveniles: it is not unknown in particular, for example, for juvenile humpbacks to approach the boat and spyhop to get a better look at the humans aboard. In recent years it is also not uncommon to see these animals playing and feeding in harbors, including New York City or Boston where fish species of interest to the whales have lately returned in astonishing numbers. As of 2011, an expert from Cornell University has recorded the vocalizations of six whale species including the humpback, the fin whale, and the massive blue whale within close proximity of the Verrazano-Narrows Bridge in the lower portion of New York Harbor and there is at least one company offering marine life tours out of The Rockaway Peninsula in Queens. Due to these increasingly frequent visits, new laws address the safety of boaters, commercial fishermen, and the whales themselves: off the coast of Boston, for example, cargo vessels must slow down to protect the much slower North Atlantic right whale and there is talk of erecting an apparatus for the much more heavily trafficked waters surrounding New York City that can warn boats of a whale's presence and location so as to avoid accidentally striking the animal. Because of the relative diversity of whales and dolphins within easy access of shore, cetacean research takes place at Woods Hole Oceanographic Institute, and the Riverhead Foundation among other centers.
Eastern Canada has many whale watching tours in Newfoundland and Labrador, Nova Scotia or New Brunswick. Twenty-two species of whales and dolphins frequent the waters of Newfoundland and Labrador, although the most common are the humpback, minke, fin, Beluga and killer whales. Another popular whale-watching area is at Tadoussac, Quebec, where Belugas favor the extreme depth and admixture of cold fresh water from the Saguenay River into the inland end of the Gulf of Saint Lawrence. Humpbacks, minkes, fin and blue whales are also frequently seen off Tadoussac.The Bay of Fundy is an equally important feeding ground for large baleen whales and dozens of other creatures of the sea; it shares a population of migrating humpbacks with America and is a known summer nursery for mother right whales with calves.
