Southeast Alaska Inventory & Monitoring Network

Oceanographic researchers

Researchers raise an instrument array from 1,300 feet in Glacier Bay during winter as part of SEAN's ongoing oceanographic monitoring program.

Sitka salmon

Salmon flood into Sitka National Historical Park to spawn. SEAN tracks Indian River streamflow and water quality as it enters the park.

Weather station

Network associates erect a weather station for climate monitoring on the ridge above Chilkoot Pass in Klondike Gold Rush National Historical Park.

Kittlitz's Murrelet

SEAN uses distance sampling techniques to estimate the summertime abundance of rare Kittlitz’s murrelets in Glacier Bay National Park and Preserve.

Intertidal Survey

The network is developing an intertidal monitoring program along Sitka National Historical Park's shoreline.

School presentation

Network staff enjoy participating in educational outreach. Here, Chris Sergeant works with Juneau schoolchildren at a recent GeoFest.


The Southeast Alaska Network (SEAN) implements long-term ecological monitoring and provides scientifically sound natural resource information to park managers. The parks in our network share the temperate rainforest of Alaska's maritime coast, but each display their own unique character: from the dynamic tidewater glaciers and rugged outer coast of Glacier Bay National Park and Preserve, to the steep and diverse landscape of Klondike Gold Rush National Historical Park, to the protected intertidal shoreline and salmon-rich waters of Sitka National Historical Park. SEAN works closely with each park to prioritize and develop long-term programs that track the condition of their natural resources.

This web site is the authoritative dissemination location for SEAN’s data and information products. SEAN hopes it is equally useful to park managers, staff, other scientists, and interested public. We always welcome your feedback on how to improve site content.
