The UPAL sensor is a novel underwater instrument that provides real-time processing of underwater sound for continuous acquisition, classification and quantification of geophysical, biological and anthropogenic sounds. Due to its adaptive and low power sampling, UPAL can be used for long-term observations of both near-shore and deep-ocean environments to support a variety of offshore applications.
The UPAL sensor was developed in collaboration with Dr. Jeff Nystuen (University of Washington Applied Physics Laboratory) under NSF Physical Oceanography funding.
