WP2: Full Seafloor Spectrum
This WP consolidates the cross-WP tasks of dataset selection and validation, reducing work in each WP and choosing datasets with more cross-WP interest. This WP will also quantify seismological noise levels and compile a a full-spectrum vision of the results of WPs 3-5.
Objectives
- Establish a catalogue of existing data (by oceans and world regions) and how to access them.
- Establish a catalogue of ocean bottom noise signals and their sources.
- Determine the seafloor pressure noise floor.

Details
Task 2.1: Dataset identification and validation
● 2.1.1: Catalogue existing databases and their characteristics (access method, region, sensors, seasons…) ● 2.1.2: Evaluate the interest of each dataset according to the needs of WPs 3-5 ● 2.1.3: Select data sets based on the above criteria ● 2.1.3: Validate data access and specify the access method for each selected data set
Task 2.2: Pressure noise bounds
For the chosen data sets and other large or spatially isolated datasets, we will confirm instrument responses and calculate Probabilistic Power Spectral Densities to determine upper and lower bounds of seafloor pressure signals.
Task 2.3: Seismological noise source catalog
Combining the noise sources identified by WPs 3-5 with other sources in the scientific literature.
