Objectives: the main objective of this project is to develop a new
method for underwater acoustic tomography that uses as source signal the
noise emitted by ships of opportunity, received on vertical arrays distributed
along the coast, with the objective of measuring the water temperature and
currents of oceanographic interest.
Sea trial: the first sea trial under this project took place during
the 9-29 October 2000, in Tróia-Setúbal, Portugal. The sea trial
was organized by Instituto Hidrografico, Lisboa, Portugal and
CINTAL-Universidade do Algarve, Faro, Portugal and involved the oceanographic
research ship NRP D.Carlos I, from the Portuguese Navy. Several instrumentation
was used during the various events of the sea trial, in particular for TOMPACO
a 16-hydrophone VLA was used together with an HGX-90 acoustic sound source
(see Intifante00 for more details
regarding the sea trial).
Intifante'00 Workshop: a first workshop to discute preliminary results of the Intifante'00 sea trial took place at CINTAL - University of Algarve, Faro, Portugal from 10-11 May 2001 (program).
