Justification
Justification

  • GLBA is quintessentially marine.

  • Virtually every park resource is strongly connected to the marine environment.

  • Virtually every park management issue is strongly connected to the marine environment.

Objective
Objective

Compile dataset of oceanographic conditions:

  • Seasonal and interannual changes in oceanographic parameters.

  • Spatial and temporal variation in distribution and abundance patterns of marine organisms.

Technical approach
Technical Approach

Hydrographic surveys:

  • 22 stations bi-annually (resolve annual signals and detect long-term trends)

  • 8 stations monthly (resolve seasonal signals)

    Core parameters:

  • temperature, salinity, light penetration, turbidity, fluorescence, dissolved oxygen.

What We’re Learning

  • It is as we thought.

  • High interannual variability.

  • Ecosystem coupling.

  • High primary production.

  • THIS is why people come to Glacier Bay.

Why it matters
Why it Matters

  • Ocean resources and processes drive GLBA

  • These resources are the core of the park

  • The single most important annual event in GLBA

  • Effective, wise management decisions
