Interrogation Site Metadata
GRB - Lower Green River Barge Puget
Status: Active - Operations UnspecifiedGeneral Operational Period: Seasonally
Start Date: 3/25/2021 12:00 AM
The purpose of this interrogation site is to detect all outmigrating juvenile salmonids leaving the Green River prior to entering the tidally influenced Duwamish. The interrogation site is a West Fork Environmental (WFE) barge array, anchored to the overhead bridge piers of Southcenter Blvd (Tukwila, WA). The barge array consists of six, 8ft WFE FINs (Fish Interrogation Nodes) suspended vertically from the barge, 4ft apart. The six FINs are grouped into two antennas, with each individual antenna containing three FINs. Two IS1001 transceivers power each antenna and are connected to a Biomark MTS-MC. Power is delivered by a 500W solar array and battery bank stored on the barge. The site is connected to a cellular modem and can be remotely downloaded. The site is operated seasonally from February through July as grant funding allows.
