Sea levels began to rise 7,000 years ago, eventually separating the islands and linking Cook Strait to the Tasman Sea. [5] In Māori legend, Cook Strait was discovered by Kupe the navigator. Kupe followed in his canoe a monstrous octopus called Te Wheke-a-Muturangi across Cook Strait and destroyed it in Tory Channel or at Pātea.
The link crosses Cook Strait, between the two islands, using submarine power cables laid along the sea floor. HVDC is more suitable than AC for transmission over long distances, and particularly where submarine cable transmission is required, because it is typically more economic, and has lower energy losses, despite the high costs of the AC/DC ...
A meandering depression within the trough like structure, the Hikurangi Channel (also known as Hikurangi Sea Channel or Hikurangi Seachannel), commences in the south and trends to the eastern side of the trough. By the latitude of Cook Strait the channel is about 80 m (260 ft) below the general level of the trough. [10]
Named after James Cook, who was the first European to sail through it, the Cook Strait is just 23 km wide at its narrowest point, so on a clear day it is possible to see across the strait. However, it is also renowned as one of the roughest and most unpredictable stretches of water in the world, owing to strong winds, conflicting currents and ...
The difference in sea level can drive tidal currents up to 2.5 metres per second (5 knots) across Cook Strait as well as into the Tory Channel. [ 5 ] [ 10 ] An unusual complication is that although there are two spring tides a month on the south side, the north side has only one spring tide a month, as shown in the plot.
A magnitude 5.7 earthquake struck near New Zealand's capital city of Wellington, government seismic monitor GeoNet said on Sunday, but initial reports indicated there were no injuries or ...
The Marlborough Sounds (te reo Māori: Te Tauihu-o-te-Waka) are an extensive network of sea-drowned valleys at the northern end of the South Island of New Zealand. The Marlborough Sounds were created by a combination of land subsidence and rising sea levels. [1] According to Māori mythology, the sounds are the prows of the many sunken waka of ...
On one side is Cook Strait with a tidal range up to 2 metres (6.6 ft), and on the other side is Tasman Bay with a tidal range up to 4 metres (13 ft). [9] This can result in substantial pressure gradients across the pass, complicated by a phase or time difference of about 25 minutes between the high tides on either side. Peak flow in the throat ...
