Activity: Invasive Species Monitoring

Contact: Gary Freitag, M.S. Oceanography, Program Agent, Alaska Sea Grant Marine Advisory Program


The purpose of today’s activity: To monitor Southeast waters for the presence of the invasive European green crab and capture snapshots to record the number and types of animals released from the trap.

These monitoring efforts:

  1. Test Auke Bay waters for either the presence or absence of the invasive European green crab; they have been recently been found within 100 miles of the Alaskan boarder as zooplankton!
  2. Use photography to provide baseline data on the ecology of Auke Bay.
  3. Provide an opportunity to learn about some of the area’s ‘less popular’ marine animals.

All of the above activities are considered “citizen science”, which is scientific research conducted, in whole or in part, by amateur scientists or lay persons. The process of science (or citizen science) can be tedious at best; however, it is many small observations over time that can lead to significant truths. By participating in this tour, and its citizen science projects, you are contributing to a better understanding of the nature of Southeast Alaska.
