深海生物多样性Ningaloo峡谷
关于深海生物多样性知之甚少,澳大利亚内外很少有深海地区被广泛采样。许多物种仍然未被发现和未命名,一个最近的探险对于西澳大利亚州的Ningaloo Canyons来说,提出了一些令人兴奋的发现。
西澳大利亚博物馆的Nerida Wilson博士和她的团队最多记录了30种新物种abolemiawhich the team estimates to be up to 47 m (154 ft) long. The expedition was conducted by scientists from the Western Australian Museum, Curtin University, Geoscience Australia, Scripps Institution of Oceanography and Schmidt Ocean Institute.
在20个潜水和180个小时的过程中,团队探索了Ningaloo Canyons,包括Cape Range Canyon和Cloates Canyon,深度为4,500 m(14,765英尺)。
使用命名的4K启用ROVsupastian, the team documented a huge array of marine life. Some have never been seen in the area before, including glowing Taning’s octopus squid, long-tailed sea cucumbers, and other molluscs, barnacles and squat lobsters.
在视频的一部分中,ROV发现了一个鲜红色的巨型水力体,在Cape Range Canyon的2497 m高1 m(3.3 ft)的身高超过1 m(3.3 ft)。

The remote Western Australian coast (Eastern Indian Ocean) is known for its extensive karst system and network of subterranean water bodies, supporting an incredible diversity of evolutionarily significant fauna. In stark contrast, the deep sea environment adjacent to this celebrated area remains almost unexplored.
Major patterns of marine biodiversity appear to be strongly related to temperature, so exploring marine areas near known terrestrial hotspots offers an effective strategy for identifying undiscovered biodiversity. To counter the information deficit found in Western Australian coast, the interdisciplinary team on this expedition plans to actively survey a significant and biologically unexplored submarine canyon, Cape Range Canyon.
该探险队的许多发现已被发现,并将在西澳大利亚博物馆展出。关于观察结果收集的所有数据均可公开供科学家研究。[施密特海洋研究所]
