Viscount Melville Sound,

250 mi (402 km) long and 100 mi (161 km) wide, arm of the Arctic Ocean, Northwest Territories and Nunavut, Canada, between Victoria and Prince of Wales islands on the south and Melville and Bathurst islands on the north. It is a section of the Northwest Passage. Through McClure Strait on the west it is linked with the Beaufort Sea; Barrow Strait and McClintock Channel lead east and southeast. A crossroads of arctic waterways, it is navigable only under favorable weather conditions. The western part was explored (1850–53) by Sir Robert McClure.

West of Cape Walker the southern land disappeared altogether; there, although Parry did not realize it, Parry Channel widens out into Viscount Melville Sound. Finally, southwest of Melville Island, Parry saw a coast to which he gave the name Banks Land (Parry, 1821:52-74, 238, 265).
He reported (1851:102; see also Barr, 2016) that "huge masses of ice" were pressed up into ridges, sometimes resembling "a heavy cross sea suddenly frozen solid." However, Osborn did not realize he was looking at a channel through which a large part of the Viscount Melville Sound ice was carried to the southeast.
He wintered in the ice near the strait's northern end, and after a short sledge journey was able to confirm on 26 October 1850 that it opened into Viscount Melville Sound. Although Melville Island was not visible, the explorers' sight reportedly (Osborn, 1856:138) "embraced a distance which precluded the possibility of any land lying" between them and it.
Eleven of 12 adults made forays outside EAG and PAS to distant areas, including Prince of Wales Strait (7 seals), Viscount Melville Sound (6), Minto Inlet (4), western Amundsen Gulf (4), and six other zones.
Filtered locations were grouped into 13 geographic zones: EAG, western Amundsen Gulf, PAS, Coronation Gulf, Dolphin and Union Strait, Darnley Bay, Franklin Bay, Minto Inlet, Eastern Beaufort Sea, Prince of Wales Strait, Viscount Melville Sound, M'Clure Strait, and McClintock Channel (Fig.

The best-documented sighting during this period was by biologist Mitch Taylor: during a helicopter survey of Viscount Melville Sound on 4 May 1991, he observed a grizzly bear on the sea ice (73[degrees] 47'N, 112[degrees] 17'W) about 60 km south of the Dundas Peninsula, Melville Island (Taylor, 1995).
Belugas, once viewed as shallow-water creatures, were revealed to be regular summer visitors to deep trenches in Peel Sound (Richard et al., this issue: 207-222) and Viscount Melville Sound (Richard et al., this issue: 223-236).
They spent much of their time offshore, near or beyond the shelf break and in the polar pack ice of the estuary, or in Amundsen Gulf, M'Clure Strait, and Viscount Melville Sound. The movements of tagged belugas into the polar pack and into passages of the Canadian Arctic Archipelago suggest that aerial surveys conducted in the southeastern Beaufort Sea and Amundsen Gulf may have substantially underestimated the size of the eastern Beaufort Sea stock.
Amundsen Gulf, M'Clure Strait, and Viscount Melville Sound are comparatively deep bodies of water (maximum depths = ca.
In the Beaufort Sea and Baffin Bay regions, they also seek deep areas (300-600 m) in the summer, particularly in Viscount Melville Sound, Amundsen Gulf, and Peel Sound (Smith and Martin, 1994; Richard et al., 2001 a, b).
In 1993 and 1995, most males tagged in the Mackenzie Estuary moved to Viscount Melville Sound, where they remained in a deep trench 500+ m deep (Richard et al., 2001a).
