XX-X) Lecture MWF 100-150 in SH 1431
Disc 1 - W 3-4 Disc 2 - W 5-6 All in Ellison
2620 A systematized introduction to marine
resources focusing on the physical and biological
environment of the California Current and our
interactions with it. Resource topics to be
covered include fishery management, marine
reserves, pollution, recreation, and agency
interactions. Several lectures will be presented
by outside experts. Website http//www.icess.ucs
b.edu/davey/Geog158/ Grading will be based on
success on examinations and a project performed
in the discussion sections. The midterm will
count 30, the final will be 40 and discussion
participation and project will count 30.

Intro to Marine Resources

• Introduction to marine resources focusing on the
  California Current
• Topics include fisheries, conservation,
  pollution, recreation, mineral extraction,
  governance, etc.
• Systems approach - links valued resource to the
  environment

6
Approach

• Take a systems approach
• Interlocking processes
• Build on physical biological processes
• Focus on inter-relationships among factors
• CA Current is a template for other regions

7
Hot Topics

• Marine Life Protection Act (MLPA) in SoCal
• Salmon fishery closure in CA OR
• Ocean acidification
• Aquaculture
• Harmful algal blooms
• Huntington Beach water quality
• Montrose chemical plant DDT tailings

8
How are marine resources connected?

• Fisheries
• Needs prediction of sustainable level of
  harvest, organism life history, food, habitat,
  fishermen behavior, markets for fish, etc.
• Petroleum extraction
• Needs location, risk in extraction transport,
  disposal of by-products, etc.
• All these linked to environmental processes

overfished

Flow, Fish Fishing

• Human-natural system biocomplexity project
• Oceanography, population dynamics, marine
  ecology, fishery management, fisherman behavior
  economics all wrapped up together
• Focus on California nearshore fisheries role of
  uncertainty in management
• Contribute to expertise data to MLPA process

Summary

• A systematized view of marine resources
• Need to understand the environment, our valued
  resources their interactions
• Time / space scales
• Time scales run from minutes to decades
• Tides to climate oscillators
• Human time scales catch / markets
• Geography is important
