TEMPO: a new ecological module for studying deep-sea community dynamics at hydrothermal vents
Provedor de dados: 5
Autores: Sarrazin, Jozee; Blandin, Jerome; Delauney, Laurent; Dentrecolas, Stephane; Dorval, Philippe; Dupont, Jacky; Legrand, Julien; Leroux, D.; Leon, Pierre; Leveque, Jean-jacques; Rodier, Philippe; Vuillemin, Renaud; Sarradin, Pierre-marie.
The major goal of this project, elaborated in the frame of the STREP Exocet/D European project, was to design a first autonomous long-term imaging module equipped with a deep-sea video camera, adequate lightning and sufficient energy storage while taking advantage of most recent progress in imaging and photonics. The new ecological module TEMPO was tested and deployed during the Momareto cruise held from August 6 to September 6, 2006 on the new French oceanographic vessel Pourquoi pas?, with the ROV Victor 6000. The scientific objectives of the Momareto cruise were to study the spatial and temporal dynamics of hydrothermal communities colonizing the MoMAR zone, located on the Azores Triple Junction.

EMSO Azores Deep-sea Observatory : 9 years of operations
Provedor de dados: 5
Autores: Legrand, Julien; Sarradin, Pierre-marie; Cannat, Mathilde; The Emso Azores Regional Team,.
The MoMAR “Monitoring the Mid-Atlantic Ridge” project was initiated in 1998 to study the environmental instability resulting from active mid-ocean-ridge processes at hydrothermal vent fields south of the Azores. It is a component of the EMSO European Research Infrastructure Consortium, which coordinates observatory regional facilities in European seas (http://emso.eu). The EMSO-Azores observatory focuses on two main questions: What are the feedbacks between volcanism, deformation, seismicity, and hydrothermalism at a slow spreading mid-ocean ridge and how does the hydrothermal ecosystem couple with these sub-seabed processes? The uncabled observing system was first deployed in 2010 in the Lucky Strike hydrothermal vent field (Mid Atlantic Ridge) at 1700 m...

The EGIM aims to set up a number of ocean locations where the same set of core variables, including temperature, conductivity, pressure, dissolved O2, turbidity, ocean currents, and passive acoustics, are measured homogeneously: using identical hardware, the same sensor references, the same qualification methods, the same calibration methods, the same data format and access, and the same maintenance procedures. The EGIM provides all the services required to ensure the best measurement quality and long-term reliability in line with the Best Practices Handbook by FIXO3 and ESONET-EMSO Label, these services being sensor power distribution, time stamping, data storage and backup, protection against the environment and against fouling and bi-directional...

A New Process for Extracting Alginates from Laminaria digitata: Reactive Extrusion
Provedor de dados: 5
Autores: Vauchel, Peggy; Kaas, Raymond; Arhaliass, Abdellah; Baron, Regis; Legrand, Julien.
Alginates are natural polysaccharides that are extracted from brown seaweeds and widely used for their rheological properties. The main step in the extraction protocol used in the alginate industry is that of alkaline extraction. A batch process is used for this step, which is time-, water-, and reactant-consuming. The possibility of extracting by reactive extrusion was investigated. The reactive extrusion process appeared to be more efficient than the batch process for the alkaline extraction of alginates from Laminaria digitata in several key ways: Time demand is reduced from about an hour to only few minutes, water and reactant requirements are divided by more than a factor 2, extraction yield is 15% higher (relative enhancement), and the rheological...

A study of the temporal dynamics of iron concentrations and temperature on a faunal assemblage at the Lucky Strike vent was performed using the Tempo ecological module at the EMSO-Azores deep-sea observatory. The CHEMINI in situ analyzer was implemented on this structure to determine reactive iron concentrations in unfiltered seawater samples along with a temperature probe. Stability tests were performed on the CHEMINI analyzer before deployment (optical module, hyperbaric tests, and deep-sea calibration) for long-term in situ analysis of reactive iron (six months, 2013–2014) at the Tour Eiffel active edifice. Recorded daily, the in situ standard (25 \mu mol.L {}^{-1} ) showed excellent reproducibility (1.07%, n=522 ), confirming satisfactory analytical...
