Project I.3.3b: Re-locatable underwater stations - Acoustic Nodes

Project Name: I.3.3b Re-locatable underwater stations - Acoustic Nodes
Project Leads: Tim McGinnis and Bruce Howe

Project Description
Bottom nodes with underwater acoustic telemetry.

The Acoustic Nodes will consist of 2 riverbed nodes in the North Channel of the Columbia River near the Astoria Meglar Bridge. The battery operated nodes will be remotely located without a cable connection. They will initially include CTD and ADP instruments and will be able to communicate via acoustic modem with the SATURN SWAP2 network node that is installed on Pier 11 of the Bridge. These nodes will be programmed to collect data on a specified schedule and sample rate, logging the data internally and periodically (hourly) transmitting the data to shore via acoustic modem connected to the Internet through the SWAP2 network. In addition, they will be able to be remotely programmable to change sample parameters, etc.
