Project Activity Scope (from Technical Overview Chart): Sensors and Devices through Integrated Systems

PNNL Solution:

  • Three large outdoor tanks with direct seawater circulation provide space for sensor and instrumentation testing
  • Water supply controls and tank set-up (vegetation, marine life, etc.) can be configured for desired test conditions
  • Tank testing: a) demonstrated dual-frequency identification sonar (DIDSON) ability to detect small fish and b) tested products for reducing biofouling of underwater sensors

Capabilities Employed to Meet Client Needs: Test planning, test performance, instrumentation system setup, and data analysis. (Additional information.)
