Objectives: of this sea trial fullfil the general requirements of WEAM (PTDC/ENR/70452/2006) and PHITOM (PTDC/EEA-TEL/71263/2006) projects.
The WEAM project objectives were to obtain data to prove the field calibration concept: the uncertainty of the predictions of acoustic propagation features can be significantly reduced, even with scarce environmental data, given that relevant acoustic parameters obtained by acoustic inference are integrated in the prediction sequel.
The PHITOM objectives were to obtain data to apply techniques of ocean acoustic tomography (OAT) to the HF signals used in digital communications incorporating into the receiver some awareness of the environment and the spatial configuration of the acoustic link.

1. to acquire acoustic data for geoacoustic charcaterization of an area of potential interest for wave energy conversor equipment;
2. to acquire data to calibrate an acoustic model for the area;
3. to test different sampling schemes to optimally sample the area;
4. to acquire underwater communications data using various digital modulation techniques (QPSK,OFDM);
5. to test MIMO and SIMO communication techniques.
