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:
Long-term monitoring of the vent habitat dynamics was made with the following environmental measurements also provided in the DOI:
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.

The TEMPO ecological module deployed from 2012 to 2019 is equipped with a SMOOVE camera and is part of the EMSO-Azores observatory.
Autonomous iButton® probes (Thermochron) deployed in the field of view from 2014 to 2019.
The underwater vehicle (ROV Victor6000/HOV Nautile) are equiped with a CHEMINI and temperature sensors.
