Abstract

Evidence of hydrothermal venting on the ultra-slow spreading Gakkel Ridge in the Central Arctic Ocean has been available since 2001, with first visual evidence of black smokers on the Aurora Vent Field obtained in 2014. But it was not until 2021 that the first ever remotely operated vehicle (ROV) dives to hydrothermal vents under permanent ice cover in the Arctic were conducted, enabling the collection of vent fluids, rocks, microbes, and fauna. In this paper, we present the methods employed for deep-sea ROV operations under drifting ice. We also provide the first description of the Aurora Vent Field, which includes three actively venting black smokers and diffuse flow on the Aurora mound at ~3,888 m depth on the southern part of the Gakkel Ridge (82.5°N). The biological communities are dominated by a new species of cocculinid limpet, two small gastropods, and a melitid amphipod. The ongoing analyses of Aurora Vent Field samples will contribute to positioning the Gakkel Ridge hydrothermal vents in the global biogeographic puzzle of hydrothermal vents.

冰冷的海洋下的热喷口:奥罗拉喷口场，Gakkel岭，揭示

自2001年以来，在北冰洋中部超缓慢扩张的Gakkel Ridge上有热液喷口的证据，2014年在Aurora喷口区获得了第一个黑烟的视觉证据。但直到2021年，人们才首次对北极永久冰层下的热液喷口进行了遥控潜水器(ROV)潜水，从而收集了喷口流体、岩石、微生物和动物。本文介绍了在浮冰下进行深海ROV作业的方法。本文还首次描述了位于Gakkel Ridge(82.5°N)南部约3,888 m深度的极光丘上的三个活跃的黑色烟囱和漫流。生物群落以球虫类帽贝一新种、小腹足类两足类一种为主。正在进行的极光热泉样品分析将有助于在全球热液喷口的生物地理学难题中定位Gakkel Ridge热液喷口。

期刊介绍： First published in July 1988, Oceanography is the official magazine of The Oceanography Society. It contains peer-reviewed articles that chronicle all aspects of ocean science and its applications. In addition, Oceanography solicits and publishes news and information, meeting reports, hands-on laboratory exercises, career profiles, book reviews, and shorter, editor-reviewed articles that address public policy and education and how they are affected by science and technology. We encourage submission of short papers to the Breaking Waves section that describe novel approaches to multidisciplinary problems in ocean science.
