Southeast Alaska NetworkInventory and Monitoring Program

Oceanography

Glacier Bay National Park and Preserve

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

Compile dataset of oceanographic conditions:

• Seasonal and interannual changes in oceanographic parameters.

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

Inventory and Monitoring Program

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.Southeast Alaska Network

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.
