远远低于太平洋的表面,四分之三的一英里深,是水下山的巅峰。距离大卫海山脉越来越1.4英里,戴维森海队长近26英里长,宽8英里,是美国水域中最大的已知海山之一。戴维森含有丰富的生活,包括大型泡沫冠和玻璃海绵的珊瑚礁。生活在海山上如此丰富, 我们提出了近十年前 戴维森海山与其密集的无脊椎动物聚集可以作为许多物种的来源,附近的峡谷和加州海岸的岩石露头。戴维森可能是一个完美的栖息地,允许他们的人群爆炸。这位戴维森海山摇篮当时可以作为将个人迁移到附近其他不太完美的栖息地的来源。这个想法 戴维森作为生物多样性来源是有乐器 在获得戴维森 2009年增加到蒙特利湾国家海洋庇护所(MBNMS).

在戴维森海山观察到八达通,海洋栖息地约80英里到蒙特里西南部。 (海洋探索信托/ NOAA)

Noaa,MBNMS和Nautilus的最近探险,返回戴维森海山。并且是典型的大卫在一起的生活展示。   超过1,000个小尺寸章鱼的人 muusoctopus rubustus. 抓住了视频 在育雏位置拥抱岩石。目前尚不清楚为什么这些章鱼正在使用海山作为托儿所。海山周围的较高电流可能会带来更多含氧水域。其他动物的致密聚集可以提供丰富的猎物。这座旧火山的裂缝,裂缝和岩石碎石可以提供掠食者的庇护。

Craig McClain is the Executive Director of the Lousiana University Marine Consortium. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Additionally, Craig is obsessed with the size of things. Sometimes this translated into actually scientific research. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (http://jiaxiangsuji.com/), a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
