PDO - Columbia River Rkm 75 OR
Status: Active - Operations UnspecifiedGeneral Operational Period: Seasonally
Start Date:
In-river detection system consisting of up to four 8ft x 20ft antennas in the Columbia River Estuary. The array (PDO) is located at river km 76 (46.148131˚N, -123.297803 ˚W), is operated by NOAA Fisheries, and was installed on 4/18/2025 for continuous monitoring, targeting detections of migrating juvenile salmonids. The array includes a Biomark IS1001 transceiver (firmware v 1.7.2), with an individual IS1001 reader assigned to each antenna. Electronics and solar are housed in a floating barge tethered downstream of the dike. Remote communication will be provided via a cellular modem. Antenna groups are based on orientation relative to the pile dike, starting with the terminal king piling of the structure. We intend to operate this site annually from March through September.

Configuration
Configuration metadata includes details about the equipment used at the site to detect and record PIT tags. A new configuration sequence record is created when equipment is added or removed from the site and the period of time it was active. A configuration sequence without an End Date is currently active.
