Abstract DSMZ-MBNMS Outcrop Vent and Non Vent community composition from still images collected with ROV Hercules on NA117 contains the observations of community to the family level in 8 vent and non-vent zones around the Octopus Garden and Octocone. Also included are location, subtrate, zone type, TASSE variable values: Easterness, Mean Depth, Northerness, Topographic position index (RDMV), Slope, Standard Deviation, and Surface Depth, BRESS geomorphon, and averate temperature. Methods Observational data was collected by manual identification of 1-minute interval still images in the DSMZ-MBNSM NA117 videos available at: https://www.youtube.com/playlist?list=PL41b0O3MiKnZjVYKiC8zunwc7tGS9L2Az . Observations were identified with the aid of deep sea guides*: HURL, NOAA, and MBARI. BRESS and TASSE variables were extraction for bathymetric grids availble via Marine Geoscience Data System under Compilations as OctopusGarden_MBARI. Substrate was identifed manually. Temperature data was collected in NA-117 with ROV Hercules. Vent and Non-Vent zones were defined by temperature. Environmental and Community data for each image sample were complined in QGIS. Data is identifed as Q for qualitative and C for catagorical. Substrate Catagories: 0: Sheet, 1 Bare Rock, 2 Carbonate, 3 Blocky sheet pillow lobate, 4 Lobate, 5 Pillow, 6 Sediment, 7 Lobate Pillow Mix, 8 Lobate Broken Pillow Mix, 9 Lobate Pillow Contact, 10 Sediment Lobate Contact, 11 Lobate Sheet Mix, 12 Lobate Sediment Mix, 13 Lobate Sheet Contact, 14 Sediment Pillow Mix. BRESS Categories: 1 Flat, 2 Footslope, 3 Ridge, 4 Shoulder, 5 Slope, 6 Valley. Vent/Non Vent Catagories: 1 Non-Vent, 2 Vent.

## 数据集摘要
本数据集为DSMZ-MBNMS露头喷口与非喷口群落组成数据,基于遥控无人潜水器大力神号(ROV Hercules)在NA117航次采集的静态图像生成,涵盖章鱼花园(Octopus Garden)与奥科康(Octocone)周边8个喷口及非喷口区域的群落组成观测数据,鉴定精度至分类学科水平。
数据集同时包含采样点位置、基底类型、区域类型,以及TASSE系列变量值:东向度(Easterness)、平均深度(Mean Depth)、北向度(Northerness)、地形位置指数(Topographic Position Index, RDMV)、坡度(Slope)、标准差(Standard Deviation)、表层深度(Surface Depth)、BRESS地貌形态(BRESS geomorphon)以及平均温度(average temperature)。
## 研究方法
观测数据通过人工识别DSMZ-MBNMS NA117航次视频中每1分钟间隔的静态图像获取,原始视频可访问:https://www.youtube.com/playlist?list=PL41b0O3MiKnZjVYKiC8zunwc7tGS9L2Az。
物种鉴定参考了以下深海生物鉴定指南:夏威夷大学水下研究实验室(University of Hawai‘i Undersea Research Laboratory, HURL)、美国国家海洋和大气管理局(National Oceanic and Atmospheric Administration, NOAA)以及蒙特雷湾水族馆研究所(Monterey Bay Aquarium Research Institute, MBARI)。
BRESS与TASSE变量提取自海洋地球科学数据系统(Marine Geoscience Data System)中以OctopusGarden_MBARI为名称的编译水深栅格数据。
基底类型通过人工目视识别确定。
温度数据由ROV Hercules在NA117航次中采集。
喷口与非喷口区域依据温度阈值进行划分。
每张图像样本对应的环境与群落数据均通过QGIS(QGIS)软件整合完成。
数据标注规则为:Q代表定性数据(qualitative),C代表分类数据(categorical)。
