Project Deliverable D50 Report on Best Practices ... - ESONET NoE

o Existing or newly developed quality control and assurance procedures.
o Interaction with manufacturer to derive recommendations for the user.
Giving reference to a use case selected from demo mission activities like the detection and
classification of marine mammals by recording acoustic signals the application of discussed methods
will be highlighted.
Working Group G2 – Infrastructure
Panel 2-1 : Cabled observatories: design comparison and tests
Chairs: Jaume Piera (UPC) and Jean Marvaldi (Ifremer)
Several subsea cabled observatories are operated or under final construction. Some elements were
presented during the First Best Practice Workshop in Bremen. This panel will update this information.
The cost evaluation performed by ESONET WP5 group will be reviewed and compared with
standalone solutions. The panel will look more carefully at one case, taking into account the scientific
objectives presented earlier in the week at the All Regions Workshop 2 in Paris. System engineering
issues for the various components of the infrastructure will be addressed.
For the remaining integration budget in ESONET, the Steering Committee decided to open a call for
the partners. The main objective of the call is to promote test of equipment and instruments on cabled
subsea observatory sites. The results of the two Demonstration Missions of Esonet showed a lack in
the field of cabled observatories experiment.
A unified proposal for test on cabled sites is under final acceptance process. It will be presented to the
panel for discussion and suggestion according to the practices of the attendants.
Objectives:
One objective is to identify the technical and cost related topics to be addressed either through
international cooperation, through the direct input of Antares, Nemo (European project operating
cabled observatories) or through additional activities proposed as a reply to the “test call” issued in
spring 2009 by Esonet.
This panel will determine the needing studies necessary to establish what are the common practices
and corresponding recommendations and write a short report on this matter (report to EMSO
Preparatory Phase).
Panel 2-2 : Stand alone observatories: design comparison
Chairs: Johannes Karstensen (IFM-GEOMAR) Jérôme Blandin (Ifremer)
This panel benefits from the experience of a large community (Animate, Var canyon, Pirata buoys,…)
and Demonstration Missions of ESONET. It is assumed that on some sites, the stand alone
observatories will be deployed to constitute a deep sea observatory infrastructure prior to cabled
observatories.
Among the topics of the panel:
o General design issues (e.g. Rating of components, knock-down prevention, materiel in use,
software, corrosion),
o Protection of surface elements: Bio-Invasions (e.g. birds, mussels), Vandalism, Safety,
o Data telemetry issues: underwater & surface ocean
o Energy management,
o Extension of deployment duration,
o Deployment and maintenance procedures,
o Implementation and exploitation costs,
o On shore organization: remote sensor control, emergency interventions,
