Central North Atlantic deep sea hydrothermal ecosystem observation: benthic ecology, image data management.
Name: Pierre-Marie Sarradin Pierre.Marie.Sarradin@ifremer.fr
Short SA Description: The observatory is multidisciplinary and offer two services in FixO3. The biology service is addressing the variability of the ecosystem around a large hydrothermal smoker called Lucky Strike. The images from a camera (SMOOVE) are the basis of the observation and are proposed as snapshots on a daily base when transmitted through the acoustic and satellite telemetry. The data from sensors positioned in the vicinity is made available and displayed in near real time through an online visualization tool in the form of graphs (data versus time). The configuration is modified every year during the maintenance cruise. The full data collected, during the previous year is uploaded and made available.
The MoMAR-EMSO-Azores observatory is set on a volcano, at the axis of the Mid-Atlantic Ridge. Its purpose is to acquire time-series data to better understand ecosystem dynamics at mid-ocean ridge hydrothermal vents. Fluid fluxes that feed these ecosystems are controlled by km-scale hydrothermal systems powered by volcanic heat, by smaller-scale near-surface fluid circulations and mixing between seawater and hydrothermal fluids, and by water column dynamics.
The yearly cruise is reported in order to help the service beneficiary to localize the data context. http://www.emso-fr.org/EMSO-Azores/Annual-cruises
The observatory configuration, map and data management process are described in http://www.emso-fr.org/EMSO-Azores/Infrastructure and the instruments characteristics in http://www.emso-fr.org/EMSO-Azores/Instruments
The SMOOVE camera images are shown as snapshots, transmitted everyday for control. They are available on http://www.emso-fr.org/charts/emsoAzores-COSTOF2-v1.0/, (4th parameter) among the graphs of all recorded parameters. This is a near real time data delivery very similar to the display of cabled observatories, although limited by the bandwidth.
The time series constituted through the near real time transmission from previous years is down loadable at any time. For example for 2015, the dataset contains the real-time data acquired from the EMSO-Azores observatory since April 2015. It is daily updated. Data are from 11 types of instruments: Geodesic GPS, Iridium GPS modem, Meteorological station, Ocean Bottom Seismometer, Optode oxygen sensor, Pressure gauges (JP), Turbidity sensor, Connected in-Situ Instrumented Colonization System (CISICS) and Communication and Storage Front-end (COSTOF). It is constituted as a DOI (such as http://doi.org/10.12770/82b184fa-05a7-4b9c-849c-d4976d544988)
The data stored yearly comprises time series of all parameters ; their availability taking into account storing or instrument failures is displayed on a single table: http://www.emso-fr.org/EMSO-Azores/Data-download.
Each dataset is made available once quality checked. As examples, the 2013-2014 iron chemical analyser dataset contains dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired between September 2013 and February 2014 (n=332) using the CHEMINI Fe, a CHEmical MINIaturized analyser (samples taken every 24 hours, with daily in situ calibration using a 25 µmol/l iron standard, Vuillemin et al., 2009). The sample inlet was positioned on the mussel bed at the base of the Tour Eiffel edifice of the Lucky Strike hydrothermal vent (1695 depth).CHEMINI Fe (CF1) was mounted on the TEMPO module which was itself connected to the SeaMON East node of the EMSO-Azores observatory
Or the images from 2011-2012, dataset contains video data acquired with the camera SMOOVE installed on the TEMPO ecological module, deployed on the EMSO-Azores observatory from June 2011 to July 2012. Data consists in two minutes video sequences recorded every 6 hours. Due to technical issues in the recording, the dataset is incomplete from April 2011 to July 2012. The instrument is connected to the Seamon East environmental monitoring node and films a mussel bed located at the base of the Tour Eiffel edifice at 1695m depth.
Images from 2016 deployment are showing the hydrothermal vent ecosystem:
