About this Lab
The PMEL Ocean Acoustics Program records and measures geophysical, biological, meteorological, cryogenic (ice), and anthropogenic sound sources throughout the global ocean using innovative acoustic technologies and sensor platforms. Its goals are to acquire long-term data sets of the global ocean acoustics environment and to identify and assess acoustic impacts from human activities and natural processes on the marine environment.
- The Ocean Acoustics Program seeks to understand the complex lineages associated with the flow of energy and material from the mantle into the overlying oceans by detecting submarine volcanic events. Also, autonomous hydrophone arrays deployed in remote ocean regions globally provide information on tectonic and volcanic events.
- Researchers capture acoustic recordings with a time series of video images of the seafloor and water column in the southern Mariana Trench to capture longer-term data sets and provide baseline information for soundscape characterization and seafloor biotic community.
- The CIMERS Bioacoustics Laboratory specializes in the collection and analysis of marine acoustic data by developing instruments for data collection as well as analysis techniques. CIMERS engineers have two decades of experience studying bioacoustic signals globally. They are experts in developing platforms for acquiring acoustics data, software tools to analyze bioacoustics data sets, species identification based on the analysis of marine mammal vocalizations, monitoring anthropogenic noise and its potential effects on marine mammals, and rare species identification in remote areas of the ocean
