Tidal currents in Glacier Bay

Tidal currents in Glacier Bay

Focus Concept:
The unique biodiversity of the Glacier Bay Marine Preserve

Sub-concepts:
The oceanography of Glacier Bay's complex fjord estuarine systems; bathymetry of Glacier Bay; the physical, chemical, geological and biological influences on the Bay's astonishing biodiversity; the interactions between the bay's complex oceanography, the abundant phytoplankton blooms and its biodiversity; the natural history of the bay and its formation; the effect of global warming on the bay's ecosystems and habitats

Generalization:
The marine wilderness of Glacier Bay National Park and Preserve includes tidewater glaciers, snow-capped mountain ranges, ocean coastlines, deep fjords, and freshwater rivers and lakes. This diverse land and seascape hosts a mosaic of plant communities and a variety of marine and terrestrial wildlife.

Guiding Question
What factors contribute to the abundant biodiversity of Glacier Bay and how can that biodiversity be maintained?
