New Zealand - Waters and seabed of Fiordland (Te Moana O Atawhenua)

"Most of the 15 fiords of Fiordland are 200-300 m deep, usually with a pronounced shallower ‘lip' near the mouth of the fiord, indicating ‘over-deepening' by the glacial ice. The longer fiords reach back into the heart of the mountains of Fiordland National Park; the head of Hall Arm, for instance, is 40 km from the mouth of Doubtful Sound. The marine environment of Fiordland is quite different from the rest of New Zealand. The deeply indented coastline has given rise to two contrasting marine environments:
(a) the wild, exposed outer coastline, with typical west coast New Zealand marine community and zonation patterns, and the preferred breeding habitat for fur seals and a wide range of ocean birds such as petrels, prions, shearwaters and penguins; and
(b) the sheltered, steep-walled fiords, which have a total shoreline length of nearly 1000 km, depths up to 420 m, and a unique inversion of usual patterns of coastal marine life." Source: UNESCO World Heritage Tentative List

have been on a boat cruise in Milford Sound - it was really awesome as it was a blue sky day. A nice multi-view showing seal, penguin and dolphin - the marine life of Milford Sound. Thanks to Adrienne of New Zealand.
