Transcript CLIVAR Current Meter DAC

National facility concerned
with looking after and
distributing marine data
Part of NOC National Marine
Facilities
Serve science, education and
industry, as well as the wider public
Our staff include research scientists
and IT specialists
Starting premise - data must be
secure and readily usable in the long
term without reference to the
originator.

Data Management Activities
Overall aim
• To manage & secure marine data for the long-term through the use of
stable & maintained data formats.
• Quality control
 Visualisation of data – “screening”
 Anomalous data points
marked (data unchanged)
 Developing more complex
automated systems
• Metadata assembly
 Oracle tables
 Link data to time, position, originator, restrictions,
documentation (instrumentation, techniques, etc.)
• Audit
• Banking
 Final version to a secure location
 Accessible via web software
• Little point in data management unless the data
are used – 72,205 requests 2012/13 (cf. 42,828
in 2005/06 & 6,366 in 2001/02)
• Direct contact requests by telephone & email
~700 last year (cf. 217 2001/02)
• BODC’s CD-ROMs - successful media for project
data ~150 last year (total 8244)
•
Online data inventories & catalogues
•
Online data delivery systems
•
BODC Web Services
•
Published Data Library
•
Download interface software
•
Near-real time data via sub-webs
• Users now expect to search for, view & receive data via the internet

Will still support the “personal”
request service
User friendly systems with GIS
interfaces
Data automatically updated every
evening
Moving to deliver all data this way
> 88,000 “series” from 148
organisations web searchable &
down load via “shopping basket”
> 20,000 in projects soon
> 2,500,000 discrete samples soon
