WP1 : COORDINATION

The project is managed by the Euro-Argo ERIC Program Manager, in close collaboration with the Euro-Argo ERIC Management Board. It covers the coordination of the technical and data management activities.

WP2 : FLOAT PROCUREMENT

The procurement has been done through a call for tenders organized by the Euro-Argo ERIC following Euro-Argo ERIC procurement rules described in the Euro-Argo Financial rules that have been validated by the Euro-Argo ERIC Council on the 18th July 2014. 

Floats are checked by the Euro-Argo ERIC personal within 3 months from delivery using Ifremer float test facilities as described in WP3/Task 3.1.

The current status is: In October 2016 all floats (150) were delivered to ERIC premises with the following schedule:

  • 40 Iridium March 2016
  • 40 Iridium May 2016
  • 20 Iridium July 2016
  • 20 Argos July 2016
  • 30 Iridium September 2016
WP3 : FLOAT DEPLOYMENT

The Euro-Argo ERIC coordinates operations at sea and associated logistics. The succession of operations is as follows : 

  • Define a deployment plan after selection of the deployment opportunities 
  • Prepare the floats and organize their shipping to the deployment location 
  • Perform the deployment itself 
  • Monitor the at-sea behavior of the float deployed
Task 3.1 : Preparing the floats

The Euro-Argo ERIC is in charge of the float preparation which involves reception and checking of the documentation delivered with the floats, checking proper functioning of all components, calibration of the sensors. It will include a tank test using Ifremer facilities that allow testing the capabilities of the floats to cycle and allows checking the T&S sensors by inter-comparing them during the test. Then mission parameters (data reduction, storage, coding, formatting etc.) and transmission schedule are programmed. Finally floats are conditioned for transport and shipping. This task also comprises the management of the stock between delivering by the manufacturer and the shipping to the deployment location.

Preparation of floats using Ifremer float test facilities

 

All floats (150) have been tested in the Ifremer pool before the end of 2016. The ERIC technical team has discovered problems with 4 floats, which were sent back to the manufacturer. Maintenance is ongoing and floats are expected to be re-delivered in April 2017. They will be tested again.

Task 3.2 : Operations at Sea

Float deployment are organized by the Euro-Argo ERIC. Float deployments require adequate logistical support and easy access to information on research cruises for deployment opportunities. Floats will be deployed during research cruises or from ships of opportunity, which must be identified. For the identification of float deployment opportunities the Euro-Argo ERIC will interact both with the Euro-Argo Members and Observers that have privileged access to their national research vessels plans, and with the Ship Coordinator of the JCOMM in situ Observing Platform Support Centre (JCOMMOPS, www.jcommops.org/), located in the same building as the Euro-Argo ERIC.

Float deployment plans are developed by the Euro-Argo ERIC taking into account international recommendations (e.g. maintenance of a global array which requires filling gaps) and specific European interests (e.g. European regional seas). Since the start of Argo (see below), European partners have mainly contributed the monitoring of the Atlantic Ocean from north to south and with a lesser proportion in the Indian and Pacific Oceans. In MOCCA, in collaboration with international partners, the Atlantic Ocean will be the first focus to contribute to an increased cooperation for Atlantic Ocean observations following the Galway declaration.

In February 2017 82 floats were shipped to deployment locations (ships, institutions etc.). 66 floats were already deployed and are operational. The remaining 68 floats will be deployed in 2017 and early 2018, taking into account the Euro-Argo and International Strategy.

Specific requirements from the Copernicus Marine Service and DG MARE/EMODNET will also be taken into account. 

Float deployments will be notified through the Argo Information Centre (AIC) up to six months prior to deployment to meet the requirements of IOC Resolution XX-6. In case of deployment from commercial vessels or sailing ships, Euro-Argo will provide training for the crews and logistical support. 

Task 3.3 : At-sea Monitoring

Monitoring of the behavior of the floats at sea will be coordinated by the Euro-Argo ERIC with the help of technology specialists (NERC-BODC, Ifremer, BSH and OGS). This monitoring will be targeted to rapidly detect failures that would need to stop deployment and also to provide feedback to manufacturers on anomalies or improvements that need to be studied.

The tools developed by Ifremer (http://www.ifremer.fr/co-techMonitoring/floatMonitoring?lang=en&groupCode=632) will be extended within MOCCA to monitor the MOCCA fleet and work toward the better monitoring of the whole European fleet. All the technical information provided by Ifremer and BODC DACs will be loaded in the Coriolis database. A technical person from the Euro-Argo Central RI will periodically analyse the float behavior and in particular the failures and provide a summary report that will be distributed to the Euro-Argo ERIC partners. It will also provide a support to cruise deployment providing rapid feedback on the data received to the persons on board if there is a set of floats to be deployed. Finally he will rely on the national experts from Ifremer, BSH, OGS and BODC for in depth analysis of failure and also liaising with float and sensor manufacturers, especially when new failure modes are identified. 

WP4 : DATA MANAGEMENT
Task 4.1 : Coordination of the data management activities

The international Argo data system is based on two Global Data Assembly Centres, a series of 11 national Data Assembly Centres and several Delayed Mode operators. Their functions are summarized here : http://www.euro-argo.eu/Activities/Data-Processing/Argo-Data-System 

The MOCCA fleet data processing is organized through Euro-Argo data centres (http://www.euro-argo.eu/Activities/Data-Processing/Euro-Argo-Data-Centres) and delegated to its members. 

Task 4.2 : Real-Time processing

UK and France will share the real-time processing of the MOCCA floats.

Real-Time data processing will be applied on the MOCCA fleet according the Argo standard procedures. See  Argo Data Management  for further details.

Task 4.3 : Delayed-Mode Processing

Although real time procedures flag the gross errors in the data, there may still remain more subtle errors due to sensor drift (most often in salinity). Elaborate procedures have been devised, based on statistical methods, and scientific expertise from principal investigators (PIs). The procedures are constantly assessed and updated as necessary. 

Delayed-Mode processing will be distributed among the 4 institutes involved in DMQC based on deployment's area:

  • OGS for Mediterranean and Black Sea
  • BSH for Nordic Seas and part of the Atlantic Ocean Floats
  • BODC for Southern Ocean floats and part of the Atlantic Ocean Floats
  • IFREMER for part of the Atlantic Ocean Floats

This activity will start in 2018 as a minimum of one year of data is needed before the delayed mode processing can be performed. 

Ifremer/Coriolis will integrate all the Euro-Argo data into the GDAC and provide user access mode adapted to different mode of use: ftp access allowing data download for operational users, and Web access allowing data visualization, selection and extraction with specific temporal and geographical criteria specified by users. 

The Euro-Argo ERIC will coordinate the data management activities and distribute the float processing to the WP4 partners according to the deployment areas. It will also coordinate with EMODNet and COPERNICUS Marine Service to ensure that the data are properly disseminated to them, gather their feedback and take actions when needed with the WP4 partners. 

Finally the Euro-Argo ERIC, with the Management Board, will analyse the activities carried out and provide recommendations for the data management of the European contribution to the Argo international programme.
