Important Distinction?

• Single Integrated Ocean Data Model
• or
• Theme-Based Sub-Models
• Deep ocean data for science and management
• Variation on ArcGIS conservation/ biodiversity
  model for coasts/oceans
• Pat and Eric

Deep Ocean Data for Science

• coordinated collection of scientific data
• geological, chemical, biological, and physical
• high level analyses of the processes and process
  interactions

Data Layers

• Marine Boundaries
• Bathymetry
• Other U/W Geophysical
• time, position, sidescan, magnetics, gravity,
  seismics
• Derived grids
• Standard supporting data
• sea state, XBT, CTD, sea surface temperature and
  salinity, and derived SVP, as well as calibration
  data for each sensor
• Images
• Locations of observations
• Submersible,ROV
• Tracklines/Nav points

10
Scientific Information Model

• Entity-attribute-relationship diagrams
• formal description of the scientific information
  requirements
• objects, places, concepts, or events, as well as
  their interrelationships
• pertinent to the real-world scenario of data
  flow and data analysis

11
SIM cont.

• Data acquisition and software will change
• e.g., new vehicles, new satellites, etc.
• Mgmt. of information that comes out of the
  acquisition systems, rather than the acquisition
  systems themselves
• ID inherent structure of oceanographic facts and
  hypotheses, rather than the structure of the
  sensor data record.
