Dynamic Ambient Noise Model Comparison with Point Sur, California, In Situ data

Abstract

This analysis was conducted to provide benchmarked performance of the Dynamic Ambient Noise Model (DANM) Version 1.0 against both in situ ambient noise (AN) measurements collected in 1998 offshore Point Sur, California, and against predicted AN spectrum levels computed with the Ambient Noise Directionality Estimation System (ANDES). First, the Point Sur data set is characterized. Next, the DANM Version 1.0 model and the ANDES model configurations are described. The first performance analysis evaluates the omni-directional predictive capabilities of DANM and ANDES. For omni analysis, the DANM and ANDES shipping components are calculated from shipping density databases. Planned for the second analysis is an assessment of the directional predictive capabilities of the DANM and ANDES models. For this planned analysis, the shipping component is calculated from both the shipping density database and discrete ship tracks.
