Several data management actions have been made in
a global international context

• 1996-1999 MTPII-MATERwww.ifremer.fr/sismer/progra
  m/mater/
• 1998-2001 MEDAR/MEDATLAS IIwww.ifremer.fr/sismer
  /program/mater/
• MFSPP-MFSTEP1998-20012003-2006
  www.bo.ingv.it/mfstep/
• meta-data Sea-search, EDIOS
• They have been made possible by the development
  of common standards and infrastructures

• WOCE/JGOFS, OMEX, CANIGO
• GODAR
• ARGO

Response
A reference good quality multidisciplinary
database gt 200 parameters collected by

• 58 research groups from 10 EU Member States and
  3 non-EU States
• 108 cruises (more than 1000 days of ship time)
• 130 long time series from fixed mooring and
  lagrangian drifters

CLIMATOLOGYMethodology

• Computation of Climatological Analysis by
  Variational Inverse Model (VIM) algorithms
• Computation made on finite elements and then
  re-interpolated on a regular grid (0.2 degrees in
  Latitude and Longitude), with smaller scales for
  local computations
• T, S and bio-chemical climatology reviewed by
  regional experts and modellers

CLIMATOLOGY - Results

• Selected numerical fields depending on data
  availability
• Annual , seasonal and monthly climatology
• Temperature, Salinity
• Annual and seasonal
• Oxygen, Silicate, Phosphate
• Hydrogen sulphide (H2S) in the Black Sea
• Annual only
• Nitrate, Nitrite, pH, Ammonium, Alkalinity,
  Chlorophyll
• No climatology
• Total Phosphorus, Total Nitrogen
• 2500 horizontal maps, vertical sections and
  data location

Standardization

• mandatory meta-data
• ISO 19115
• common exchange format(s)
• ASCII MEDATLAS
• NetCdf ARGO/MFSTEP
• quality controls
• On data
• On products
• Requested for interoperability Communication

QUALITY CHECKS

• QCO Automatic check of the format
• QC1 Automatic and visual check of the
  headers
• QC2 Automatic and visual check of the data
  points
• a quality flag to each numerical value (GTSPP
  flag scale)

30
QC1 Location, date, duplicates
31
QC-2 check of the data points

• Automatic Checks Result
• Pressure one more observation (E)
• Out of the regional scale
• (min max values)
• Increasing pressure
• Data below the bottom depth
• Coherence with pre-existing statistics (LEVITUS,
  MODB, MEDATLAS)
• No constant profiles
• Spikes
• Vertical stability
• E Elimination

32
Conclusion 1 Present available data
infrastructure and services for the Mediterranean
and Black Sea

• The data management network of NODC/DNA
  disseminate data from national and international
  programs provides basic data services
• Implementation of internationally agreed
  protocols (when available) and practices for data
  formatting and checking,
• Continuous compilation of national data, quality
  checking with feedback to source scientists,
  perennial archiving,
• Data dissemination routine regional or thematic
  subsets, and answers to specific requests,
• State of the art watch to develop standards and
  make use of the communication technology.

33
Conclusion 2 What remain to be done

• Direct internet access to the most complete and
  integrated data sets historical data data
  released in recent projects real time data
• more quality data and products such as estimates
  of the mean, decadal, seasonal, monthly
  statistics at basin, regional and shelf scales
• Insure continuity and integration with other
  Pan-European and international programs
• Avoid to stop the dynamics
• Compatibility with other networks
• Develop the standardization with ISO 19115 and
  Marine XML, especially for meta-data and
  communication
• Develop marketing to and feedback from the users
• Avoid to create new non compatible systems

34
SEA-DATANET New concerted actions in preparation

• to develop
• An internet integrated portal
• A communication protocol (ISO19115, Marine XML)
  between local systems
• Quality Control procedures to be applied on data
  and products according to the existing
  international standards or standards developed in
  the project, especially for non-physical data
• Marketing of the user community, to get more data
  and provide better services
• Enhanced international cooperation capacity
  building activities

35
Sea Data network

• a semi-distributed model that incorporates, but
  enhances, the existing infrastructures
• professional archiving centres
• scientific centres
• SMEs

Phases of Sea-Datanet

• Design study protoype of the system
• On line networking of a limited number of centre
  to provide data
• Access to all via internet
• Test of feasibility and cost estimation for any
  current parameter
• Development of the system
• On extended network of data sources
• On a limited number of parameters
• Implementation and evolution

38
Expected long term results of Sea DataNet

• Standardize, secure and disseminate the data
  holding of the Pan-European community
• Decrease or optimisation of the overall costs of
  the data management of the projects
• Training on standards and methodologies developed
  in the project
• Robust statistics and trends over the last
  decades of the physical and bio-chemical
  parameters
• A recognised Pan-European data infrastructure
  able to contributes to international programmes
  related to GOOS/MEDGOOS, CLIVAR,JGOFS..
