A Look at Both Sides of the Southern Alps, New Zealand

43.6S 170.6E

March 24th, 2011 Category: Mountains, Sediments

New Zealand - March 22nd, 2011

The Southern Alps run down the middle of New Zealand’s South Island, providing a sort of “backbone”. In this image, snow and clouds are present on the eastern side of the ridge, while the western side is clear.

Along the west coast, several rivers can be seen spilling sediments into theĀ  Tasman Sea. Sediments are also present along the northern coastline, pouring into the Cook Strait. In the full image, sediments and/or algae can be seen giving a bright blue color to several glacial lakes in the Mackenzie Basin, at the eastern foot of the Alps.


Lakes, Mountains and Volcanoes of New Zealand – August 17th, 2010

New Zealand - July 30th, 2010

The two main landmasses visible here are New Zealand’s North Island (above) and South Island (below). The two are separated by the Cook Strait.

Of note on the North Island are Lake Taupo, the dark blue lake in the center of the island, and several volcanoes: Mount Taranaki/Egmont (on a peninsula on the western side), Mount Ngauruhoe (south of Lake Taupo), and Mount Ruapehu (south of the former).

Of note on the South Island are the Southern Alps, the snow-capped mountain chain running down the backbone of the island, the sediments near the Banks Peninsula (central east coast), and the bright blue glacial lakes of the Mackenzie Basin (between the mountains and the southeastern shoreline).

Sediments Spilling from Waitaki River, New Zealand

Rivers flowing down from the Southern Alps of New Zealand’s South Island release sediments into the Pacific Ocean. One of the most noticeable of these is the Waitaki River (center of coastline), fed by streams issuing from Lakes Ohau, Pukaki, and Tekapo (left to right) in the Mackenzie Basin. Here, those lakes appear bright blue amidst the snow-capped peaks of the Alps.

The Waitaki River drains a 4,565-square-mile (11,823-square-kilometre) basin, flowing southeast for 130 miles (209 km) to enter the Pacific at Glenavy, about 70 miles (113 km) north of Dunedin. The Waitaki River Power Development, which includes several large dams, is one of the largest hydroelectric projects in the nation.

The Waitaki River is a large river in the South Island of New Zealand, some 110 km long. It passes Kurow and Glenavy before entering the Pacific Ocean between Timaru and Oamaru on the east coast of the South Island. The rivermouth can be seen towards the bottom of this image, releasing sediments into the ocean. The median flow of the Waitaki River at Kurow is 356 cubic metres per second.

The Waitaki is the major river of the Mackenzie Basin. It is a braided river which flows through Lake Benmore, Lake Aviemore and Lake Waitaki (visible in reverse order upon tracing the river’s path upstream). These are ultimately fed by three large glacial lakes, Tekapo, Pukaki and Ohau (upper right quadrant, from northeast to southwest).
