Résumé

On présente un bref aperçu des aspects pratique et théorique d'une méthode acoustique pour détecter 1'huile emprisonnée sous les glaces océaniques. On discute entre autre des modes de propagation acoustique de l'onde ultrasonique refléchie du dessous de la glace. Des mesures effectuées dans un réservoir d'eau salée avec 80 cm de glace sont comparées avec la théorie et les conséquences de cette expérience discutées. Finalement les grandes lines d'un appareil prototype sont présentées.
