Basis of this Presentation
Trawl surveys are: • widely used for assessing populations of
bottom dwelling fish and invertebrates,
• a rich source of in-situ measurements for ground truthing and augmentation of remotely sensed data,
• leading development of standards based ocean observing systems.

5) Saint Andrews Biological Station
United States6) Northeast Fisheries Science Center
Types of Observations
For 400+ species:• total weight caught• total number caught• count at length
For some species:• individual length and
weight• sex, maturity and age
Types of Results
• Species Distribution
• Fish Stock and Population Trends
• Species Life History
• Environmental Preferences
Next StepsUnder Canada’s GeoConnections Access Program:• create ANSI/ISO metadata and extend BIO access facilities
to support these standards,• serve annually updated population & distribution products
for 99 species presently on ECNASAP site,• expand population & distribution products to include all
400+ species, • where possible, provide estimates for juvenile and adult stock
components,• assist other NW Atlantic fisheries laboratories to establish
similar facilities.

Objectives
• Improve Underlying Taxonomic Collections– Digitize entire Atlantic Reference Centre fish
collection, not only for Gulf of Maine but also a major portion of the NW Atlantic,
– Create electronic atlas to facilitate study of taxonomic collections for selected areas of ocean bottom.
Next Steps
Under Canada’s GeoConnections Access Program:• establish common minimum data and image capture
facilities for CMB members,• extend ANSI/ISO metadata facilities at BIO to include
CMB member data,• extend electronic atlas to include all available Atlantic
Canada taxonomic collections,• extend atlas to cover all 3 of Canada’s oceans.
Supporting the Global Spatial Data Infrastructure
Underlying Concerns
• Need for a conceptual model that simply describes what we should be doing.– ever growing collections of highly detailed data not
being integrated into a collective whole and effectively used for decision making.
– making sense of and exploiting the growing and diverse constructs and technologies presently transforming the information management paradigm.

ManagementIntelligence
• Satisfying organization needs is the primary goal when building an information infrastructure,
• Issues of complexity and efficiency, although important are secondary,
• Operational systems provide the data from which intelligence and management information is ultimately derived.
Understanding Needs
Types of Users• Explorers - irregular access,
looking for relationships in the data, need tools for analysis,
• Farmers - regular access, knows what they are looking for, predictable, needs tools for presentation,
• Tourists - looks at lots of data on a random basis, often not at same data twice, making heavy use of metadata.
Types of Analysis• Structured - mostly farmers
and the occasional tourist analyzing data for future possible action,
• Operational - mostly farmers analyzing data for immediate action,
• Exploratory - mostly explorers and some tourists

Risks
• If we proceed without a conceptual model, differences in data management practices between the various specialist groups and regions will continue to grow.
• Continued difficulty with understanding the technical needs and resource levels both inside and outside of science.
