Sprial source test and ppcoming TRIDENT sea trial
Spiral source test, project K2D
Pool test of acoustic source to follow emitter (click below to see video)
Baseline survey sea trial, project TRIDENT'24
![tropic seamount bathymetry propagation](/proj/trident/tl50Hz_seamount.png)
Baseline survey sea trial on board R/V Mário Ruivo (IPMA) to gather
environmental status data to support WP2 tasks, and provide reference field data
for ocean bottom exploration impact estimation. Acoustic data will include a fixed point
vertical line array and an acoustic recorder equipped SeaExplorer glider from ALSEAMAR.

PAM2py
download zip or github, a Python open source version of the PAMGuide package for Passive Acoustic Monitoring that features the Exchange Data Format (EDF) for facilitated underwater acoustic data sharing and metadata handling. Python allows for a crossplatform licence free processing of raw acoustic data and EDF output. A library of Python routines for EDF data reading and writing are also available.
