marine resource management
Marine Resource Management
  • Marine resources are at risk (eg. Leslie et al., 2003, Mumby et al., 2001, Puniwai et al., 2003)
  • Growing interest in Marine Protected Areas (MPAs)
    • Management tool
    • Effective both ecologically and economically (eg. Carr et al., 2003, Friedlander and Brown, 2003, Tissot et al., 2004)

  • How can we make MPAs as effective as possible?
    • Identify areas with patterns of high habitat utilization

  • Question 2: How well does the MDM meet the needs of the marine GIS community?
conceptualizing the mdm
Conceptualizing the MDM
  • Building industry-specific data models for ArcGIS
  • In 2001, researchers decided to create a model specifically for the marine community
  • The ArcGIS Marine Data Model
what is the mdm
What is the MDM?
  • A geodatabase template
  • A new way to spatially model marine data
  • A database used to assemble, store and query data
  • Model that captures the behavior of real-world objects
why use the mdm
Why use the MDM?
  • Standardized template
    • Implement project
    • Organize data
  • GIS and data management
    • Easy to share
    • Build upon
  • Querying ability
  • Object orientation

Importing: Personalizing the MDM
  • Adding fields to the feature classes, tables
  • Adding new tables and relationships
  • Attention to detail required
  • Worth it in the end!

Does depth play a role in the location of coarse-scale habitat types?
  • Mean depth for RCB habitat type is 37 +/- 3.65ft
  • Mean depth for RA habitat type is 41.71 +/- 5.77ft

Discussion: Habitat Analysis

Future research: Tie fine-scale

substrate info be tied to specific

fish?

1. How do specific fish utilize coarse-scale habitats?

A: Inconclusive

A. WHAP Fish Info

B. Coarse-scale

NOAA habitat info

Regional Habitat

Utilization Patterns?

C. Fine-scale WHAP substrate info

3. Does depth play a role in the location of RA and RCB habitat types?

A: Strong trend, p=.088

2. Can fine-scale substrate info be correlated to coarse-scale habitat types?

A: Yes, PC (p<.05) in RA and a strong trend with PL (p=.059) in RBC

conclusions management
Conclusions: Management
  • Use information from this study to evaluate current protected areas
  • For example:
    • RA habitat shows trends toward being located deeper
    • P. compressa is found significantly more often in RA habitat
    • P. compressa provides and important habitat for yellow tang (Tissot et al., 2003, Dollar, 1982)
    • Thus, to protect the yellow tang, must have protected areas that extend into deeper waters
    • Consistent with study that MPA encompassing range to depth values shown to be more efficient for yellow tang (Tissot et al, 2004)
discussion
Discussion
  • Through habitat analysis:
    • Goal 1: Met

Discussion: Ideal User?

MDM is tailored to a specific user:

  • Data
    • Amount
    • Variety
    • Time
    • Cost
  • Experience of user
    • Experienced GIS—use object-orientation
    • Inexperienced—use template

Conclusions
  • The MDM is a powerful tool
  • Information to aid managers evaluate the West Coast MPAs
  • Future research
    • Data to HNHP
