Drift whale

Many cetacean species have been documented as drift whales, but some are more common than others. In New England, for example, the carcasses of fin, humpback, sperm, right, and pilot whales, as well as dolphins, are most likely to drift ashore.[3] Some species have a naturally high buoyancy, and float when they are dead, aided by the gases of putrefaction.[4]

Whales that live in the pelagic ocean, far from the continental shelf, are less likely to wash up ashore than coastal species.[5] Once these deep-sea animals do find themselves in shallower waters, however, they may run into difficulties, as the gradual shelving of the shoreline is thought to play a role in confusing their sense of echolocation.[6] Sperm whale strandings are known to have occurred in the North Sea for centuries, and the incidents may be increasing with louder ship noise.[6]

Aside from the whaling industry, most cetaceans have no predators other than the orca (killer whale)[7] and certain large sharks (such as the dusky[8]), which in both cases tend to attack in groups and focus on one young whale. Some drift whale carcasses show injuries consistent with attacks from these species, or, in modern times, with ship strikes (e.g., trauma from a propeller).[9][10] Another obvious and visible cause of traumatic death is cetacean bycatch, i.e., entanglement with fishing gear, which kills tens of thousands each year, according to the International Whaling Commission.[11]

Other carcasses show no visible injury, and theories about why the animals died include the possibilities discussed for live strandings (especially active sonar) as well as illness and malnutrition.[12] Sometimes a necroscopy is performed, which can reveal the cause of death, such as ingestion of plastic pollution and other Marine debris.[13]

Certain beaches are well known as likely spots for whales, and other gifts from the sea, to wash up: drift seeds, driftwood, and latterly sea glass and even messages in bottles. Modern recreational beachcombers use knowledge of how storms, geography, ocean currents, and seasonal events determine the arrival and exposure of rare finds;[14][15] the same applies to those looking out for drift whales.

Eponymous coastal features include Drift Whale Bay within Brooks Peninsula Provincial Park on the Pacific Coast of Vancouver Island.[16][17] Saint-Clément-des-Baleines on the Atlantic coast of France is named after its stranding beach.

A whale's massive carcass would provide a coastal community with considerable amounts of meat and fat, without the danger and effort of venturing onto the open ocean to harpoon a living leviathan.[21] An additional resource, in the treeless Arctic, was the long bones, useful for construction. An even more specialised benefit is the occasional presence of ambergris in the guts of sperm whales; in 2021 a group of Yemeni fishermen sold their find for $1.5 million.[22] Blubber used to be processed into whale oil.[1] More generally, whale meat is still valued in some countries; muktuk (skin and blubber) is eaten uncooked as a delicacy in the Arctic, as fat is especially welcome in very cold climates.

The bounty and good fortune inherent in this find are recognised in etymology: "The meaning of the word 'drift-whale' in Icelandic, 'hvalreki,' has the same meaning as 'wind-fall' – an unexpected good incurred at no cost", according to Sigrún Davíðsdóttir, London correspondent of the Icelandic national broadcaster RÚV.[23] Two anthropologists, Thomas Talbot Waterman and Alfred Louis Kroeber, who worked with Yurok informants in California, classified drift whales as a gathered resource, rather than a product of hunting, as those beneficiaries ran no risk.[24]

Coastal people around the world came up with a technique called dolphin drive hunting, which exploits the animals' tendency to beach themselves. This sort of hunt, which depends on substantial community co-operation, still continues in a few places, as far apart as the North Atlantic (Whaling in the Faroe Islands), the South Pacific (Malaita dolphin drive hunt), and Japan (Taiji dolphin drive hunt).

It is harder to find evidence, archaeological or ethnographic, of North American indigenous people hunting large whales before cultural contact with Europeans, according to scholars of the Atlantic[25] and Pacific[20] coasts.

The skills learned from processing drift whales, such as flensing (stripping the blubber), may have led to seeking out live ones. For example, the Makah of Washington State have been hunting gray whales for at least 1500 years, but were harvesting stranded whales for many centuries before that.[26] On the other side of North America, drift whale scavenging on the Outer Banks of North Carolina led to organised hunts, documented at the Graveyard of the Atlantic Museum.[27]

When the early settlers arrived in New England, they saw from the deck of the Mayflower a huge number of whales, far more than they were accustomed to see in European waters, according to American historian W. Jeffrey Bolster.[25]

March 1644, in Southampton, Long Island, saw the first recorded attempt of the New England colonists "to organize community efforts to hunt drift whales.”[28] The Native Americans had developed the technique of herding pilot whales onto the shelving beaches for slaughter; the colonists observed this, practised flensing the carcasses and rendering the blubber, improved on their weapons and boats, and then progressed to hunting on the ocean.[19] This early drift whaling at Southampton led gradually to the nearby Sag Harbor whaling fleet becoming the biggest in New York State, according to a curator at the local whaling museum.[29]

Tribes in Nantucket guarded and traded as sachem their ownership of drift whales assiduously. They were able to use their ownership and early treaties as a way to avoid royal taxes on the products.[30]

Some communities both hunted and scavenged. William Barr, the Arctic historian, gives two examples of the late eighteenth century: the Moravian missions on Labrador, and possibly the Inuit of Hudson Strait, who had a trading relationship with the supply ships of the Hudson's Bay Company. However, Barr assumes that the drift whales were ones that the Inuit hunters (or possibly the European whaling ships) had harpooned and wounded, and the carcasses had come ashore some time later.[31]
