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

Microbe biomass and diversity Invertebrate abundance and distribution

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 images The 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.
