Thompson Sound (New Zealand)

Last updated

Te Awa-o-Tū / Thompson Sound is a fiord of the South Island of New Zealand. It is one of the fiords that form the coast of Fiordland.

The fiord is connected at its farthest extent with Pendulo Reach, [1] part of Doubtful Sound, and between them Thompson and Doubtful Sounds form the non-Tasman Sea coast of Secretary Island. It is 21 kilometres in length. Bradshaw Sound, which extends east from the junction of Doubtful and Thompson Sounds, is geographically and geologically an extension of Thompson Sound. Several small rivers flow into Thompson Sound, among them the Pandora and Namu Rivers. [1]

Thompson Sound was named by John Grono, a sealer who worked the Firdland coast in the early 19th century, after his boat's owner, Andrew Thompson. [2] [3] Grono himself is honoured in the name of the 1196-metre Mount Grono, the highest point on Secretary Island. Later surveyor John Stokes incorrectly thought that the sound had been named after Colonial Secretary Edward Deas Thomson, and named an indentation in the sound's Secretary Island coast as Deas Cove. [2] In October 2019, the name of the fiord was officially altered to Te Awa-o-Tū / Thompson Sound. [4] Coordinates: 45°15′S167°0′E / 45.250°S 167.000°E / -45.250; 167.000

Fiordland geographic region of New Zealand

Fiordland is a geographic region of New Zealand in the south-western corner of the South Island, comprising the western-most third of Southland. Most of Fiordland is dominated by the steep sides of the snow-capped Southern Alps, deep lakes, and its steep, glacier-carved and now ocean-flooded western valleys. The name "Fiordland" comes from a variant spelling of the Scandinavian word for this type of steep valley, "fjord".
