The Queen Charlotte Sound ( Māori Tōtaranui ) is an estuary in the north of the South Island of New Zealand with access to the Tasman Sea .

geography

The 195.5 km 2 large Queen Charlotte Sound extends over some 40 km from the ferry port of Picton made in ostnordöstliche direction until his transition into the Tasman Sea between Cape Jackson on the north side and Cape Koamaru on the south side of the 11.7 km wide Access to the sound . In Queen Charlotte Sound , there are six islands Motuara Iceland , Long Iceland , Pickersgill Iceland ( Matapara ) Blimine Iceland ( Oruawairua ) Allports Iceland and Marbel Iceland . By far the largest island, Arapawa Island , extends for around 28 km on the northeast side of the Queen Charlotte Sound and delimits the sound to the southeastern Tory Channel and part of the Cook Strait .

On either side of the Queen Charlotte Sound are two large inlets, Endeavor Inlet and East Bay, as well as more than 20 large bays and a number of coves that are considered smaller bays. The depth of the sound differs on average between 30 m and 45 m, with 75 m being the second deepest point of the sound at the transition to the Tory Channel , which is called the Dieffenbach Point here . Alongside on the west side of Blumine Island there is a fault that has depths between 50 m and 80 m and thus marks the deepest point of the sound .

The tidal current of the inlet is at its center at 1 to 3  knots at the entrance to the Tory Channel and the tidal range at Picton is around 1.5 m. In the main part of the sound, the water exchanges itself once within around 31 days.

geology

Like all sounds , channels and inlets of the Marlborough Sounds , the waters consist of former river valleys flooded by the sea. While the South Island was sinking, the sea level has been rising since the last glacial period , which led to the flooding of coastal areas and coastal valleys.

Shipping

The western part of the Queen Charlotte Sound to Picton is used by Interislander and BlueBridge ferries . When coming from Wellington via Cook Strait , the ferries turn from the Tory Channel into Queen Charlotte Sound and follow it to the ferry terminal at Picton . Freight and cruise ships also use the Sound with their destination Picton . There are two marinas in Picton and Waikawa that serve as departure points for cruises in the Marlborough Sounds , Cook Strait and the Tasman Sea.

Shipping accidents

There are around 57 shipwrecks on the bottom of the Marlborough Sound , some of them in Queen Charlotte Sound . The Shamrock capsized and sank in 1834, taking 10 sailors into the depths and in 1849 the schooner Comfort with a crew of six mysteriously disappeared in the sound . But the most famous and final accident occurred on February 15, 1986 when the cruise ship Mikhail Lermontov , coming from Picton , rammed a rock near Cape Jackson and on the following day around 11 km southwest at Gannet Point in Port Gore Bay , west of the Queen Charlotte Sound , sank.
