SMARTIES cruise - Nautile videos of the axial domain of the Mid-Atlantic Ridge south of the Romanche transform fault

Videos recorded during the SMARTIES cruise with the Nautile cameras (fixed and mobile) during dives along the axial domain of the Mid-Atlantic Ridge south of Romanche transform fault. The following dives are part of this datatset: - SMA-1970 - SMA-1973 - SMA-1974 - SMA-1975 - SMA-1976 - SMA-1977 - SMA-1978 - SMA-1979 - SMA-1980 These videos illustrate different volcanic structures along the neo-volcanic zone of the ridge axis. The dives explored two non-transform discontinuities and two ridge segments between Romanche and Chain transform faults (RC-2 and RC-3). Dives SMA-1970 , SMA-1976 and SMA-1980 explored volcanic formations inside a large non-transform discontinuity between segments RC-1 and RC-2. Dive SMA-1978 explored the floor of the discontinuity between segments RC-2 and RC-3. Dives SMA-1973, SMA-1974, SMA-1975 and SMA-1979 explored different parts of the neo-volcanic ridge of segment RC-2. Dive SMA-1977 explored volcanic formations in the northern part of segment RC-3. The detailed study of these videos were published in Grenet et al., 2023 associated paper.

本数据集收录了SMARTIES科考航次期间，借助诺蒂尔号（Nautile）固定式与移动式摄像机，在罗曼什转换断层以南的大西洋中脊轴域开展潜水作业时录制的视频影像。本数据集涵盖如下潜水任务：SMA-1970、SMA-1973、SMA-1974、SMA-1975、SMA-1976、SMA-1977、SMA-1978、SMA-1979、SMA-1980。这些视频直观呈现了洋中脊轴部新火山带沿线的各类火山构造。本次潜水作业共勘探了罗曼什转换断层与查恩转换断层之间的两处非转换间断面，以及两段洋中脊段（RC-2与RC-3）。其中，SMA-1970、SMA-1976与SMA-1980号潜水任务对RC-1与RC-2段之间的大型非转换间断面内部的火山构造进行了勘探；SMA-1978号潜水任务勘探了RC-2与RC-3段之间间断面的底部区域；SMA-1973、SMA-1974、SMA-1975与SMA-1979号潜水任务勘探了RC-2段新火山脊的不同区域；SMA-1977号潜水任务则勘探了RC-3段北部区域的火山构造。针对这些视频的详细研究成果已发表于Grenet等人2023年的相关学术论文中。
