Compilation of image annotations and environmental data of 7 years of monitoring of hydrothermal assemblages using the TEMPO ecological module (EMSO-Azores observatory)

the dataset contains annotations made on screenshots of video sequences collected by the tempo ecological module from 2012 to 2019 at a frequency from infra-daily to 10 days (base of the eiffel tower hydrothermal edifice, lucky strike, mid-atlantic ridge, depth of 1695m). a long-term monitoring of the vent fauna dynamics was achieved with the files provided in this doi that includes: annotations of the substratum and of the vent fauna (bathymodiolus azoricus vent mussel) and microbial mats with polygons; annotations of the crab segonzacia mesatlantica within images; count of unidentified zoanthids (manual and automatic; codes are provided).long-term monitoring of the vent habitat dynamics was made with the following environmental measurements also provided in the doi: yearly measurements made with the chemini and temperatures probes of the underwater vehicle since momarsat2014 positions and temperatures measured by ibutton® probe in the tempo images linear regression-based modeling of the vent fluid dilution gradient in order to interpolate the ibutton® temperatures over the full set of imagesthe dataset is accompanied with rasters allowing spatio-temporal continuity of the data by masking the portions of the images that do not overlap throughout the image time series.the dataset is also accompanied with a read me to describe the structure of each data.

本数据集包含了对2012年至2019年间由Tempo生态模块收集的视频序列截图所进行的标注，标注频率介于超日到10天不等（基础为埃菲尔铁塔热液构造、幸运打击、中大西洋脊、深度1695米）。通过本DOI提供的文件，实现了对热液区生物群落动态的长期监测，包括以下内容：对基底、热液区生物（阿佐里斯浴帘贝热液贻贝）及微生物层的多边形标注；对图像中蟹类Segonzacia mesatlantica的标注；对未知珊瑚群体（手动及自动；提供代码）。此外，通过对热液区生境动态的长期监测，还提供了以下环境测量数据：自MOMARSAT2014以来，水下车辆使用的Chemini和温度探针的年度测量数据；Tempo图像中由iButton®探针测量的位置和温度；基于线性回归的建模，以插值计算iButton®温度在所有图像中的稀释梯度。数据集附带栅格数据，通过屏蔽图像时间序列中不重叠的部分，实现了数据的时空连续性。同时，数据集还附带了一份README文件，用以描述每个数据结构的构成。
