Abstract
The TRIDENT project is a European initiative, that aims at the development of technological capabilities for deep
sea monitoring of exploration activities. A particular goal of the project is the development of a computational tool
for the prediction of acoustic noise levels generated by such activities, that would include also shipping and wind
noise. A fundamental support of acoustic predictions is the development of a graphical user interface (GUI),
called the OceanSoundModel, that will seamlessly integrate the different types of input data and will also deal
with the different time and space scales of the data. While the development of a specific model describing the acoustic
noise created by exploration activities is still underway the OceanSoundModel in its current stage is already
able to produce noise maps for wind and shipping noise. The discussion presented here describes and showcases
the OceanSoundModel, and presents acoustic maps associated with AIS data acquired during the TRIDENT
Baseline Survey 2024, that took place near the Tropic Seamount; these maps were able to provide clear guidelines
for the identification of silent and noisy ships, as well as revealed important shadow effects of noise levels
induced by bathymetric features.
