Taranaki Bights, Tasman Bay and Nearby Volcanoes, New Zealand

New Zealand - November 25th, 2011

The South Taranaki Bight (middle of image) is the name given to the large bay which extends south and east from the south coast of Taranaki in New Zealand’s North Island. The North Taranaki Bight begins to the north of Cape Egmont (upper part of image).

Sediments can be seen lining the shores of both bights, and the active stratovolcano Mount Taranaki/Egmont can be seen on Cape Egmont. Further inland, Lake Taupo can be seen, with the active stratovolcano Mount Ruapehu to the south of it. The volcano is surrounded by a semi-circle of clouds, but is easily identified by its white, snow-capped peak.

Visible to the south, in the lower part of the image, is Tasman Bay, a large V-shaped bay at the north end of New Zealand’s South Island. Located in the centre of the island’s northern coast, it stretches along 120 km of coastline and is 70 km across at its widest point. It is an arm of the Tasman Sea, lying on the western approach to Cook Strait.

At Tasman Bay’s western extremity, the land around the bay is rough and densely forested. To the east, the land is also steep, with the westernmost points of sea-drowned valleys of the Marlborough Sounds. The land between these two extremes is more gently rolling, and also includes the coastal plains around the mouth of the Waimea River at the bay’s southernmost point.

Cook Strait Between New Zealand’s North and South Islands – December 10th, 2009

The Cook Strait separates the North and South Islands of New Zealand, connecting the Tasman Sea on the west with the South Pacific Ocean on the east.

To the south the coast runs runs 30 km along Cloudy Bay and past the islands and entrances to the Marlborough Sounds. To the north the coast runs 40 km along Palliser Bay, crosses the entrance to Wellington Harbour, past some Wellington suburbs and continues another 15 km to Makara beach.

Cook Strait is one of the most dangerous and unpredictable waters in the world. At its narrowest point 23 km separate Cape Terawhiti in the North Island from Perano Head on Arapawa Island in the Marlborough Sounds. Counter-intuitively, at this point the South Island coast lies further north than that of the North Island.

Other points of interest visible on the North Island in this image include Lake Taupo, the large body of water near the top, snow-capped Mount Ruapehu south of the lake, and the also snow-tipped Mount Taranaki (also known as Mount Egmont) on the left edge.

The Marlborough Sounds, New Zealand

The Marlborough Sounds are an extensive network of sea-drowned valleys created by a combination of land subsidence and rising sea levels at the north of the South Island of New Zealand.

Covering some 4,000 kmĀ² of sounds, islands, and peninsulas, the Marlborough Sounds lie at the South Island’s north-easternmost point, between Tasman Bay in the west and Cloudy Bay in the south-east. The almost fractal coastline, almost all of which is visible in this orthorectified image, contains one fifth of the length of New Zealand’s coasts.

The steep, wooded hills and small quiet bays of the sounds are sparsely populated, as access is difficult. Many of the small settlements and isolated houses are only accessible by boat.

The Cook Strait, New Zealand

Cook Strait, New Zealand - February 16th, 2009

The Cook Strait lies between the North and South Islands of New Zealand. Twenty kilometres (12 miles) wide at its narrowest point, on its north side stands the city of Wellington; on the south side lie the Marlborough SoundsĀ  and Cloudy Bay.

An algal bloom frames the northeastern coast of the South Island, particularly in Cloudy Bay. Lake Grassmere, southeast of Cloudy Bay and directly south of Clifford Bay, is filled with bright green algae.

The northwestern shoreline of South Island, on the other hand, where the bays, sounds and coves of the Marlborough Sounds are found, is clear of algae along the exterior coast. However, some is present in the interior, in the Kenepuru Sound.

The Kenepuru Sound is one of the largest of the Marlborough Sounds in the South Island. The drowned valley is an arm of Pelorus Sound, it runs for 25 kilometres from the northeast to southwest, joining Pelorus Sound a quarter of the way down the latter’s path to the Cook Strait.

Across the strait, along the North Island shoreline, algae is present only in Palliser Bay, which runs for 40 kilometres along the Cook Strait coast from Turakirae Head at the southern end of the Rimutaka Ranges to Cape Palliser, the North Island’s southernmost point.

North of Palliser Bay, Lake Wairarapa has a dense, bright green algal bloom. To its southwest, Wellington Harbor is algae-free.
