Cuvier’s beaked whale, Ziphius cavirostris, a critical species when sonar operations are concerned, is difficult to detect. Its acoustic features have been discovered recently by using sophisticated digital recording tags (DTAG) developed by WHOI (Johnson et al., 2004; Zimmer et al., 2005), but traditional sub-surface detection devices have never been proven reliable. CIBRA developed a high quality wideband towed array with the purpose of detecting Cuvier’s beaked whales, and tested it in an area hosting a known population.

Abstract
Cuvier’s beaked whale, Ziphius cavirostris, a critical species when sonar operations are concerned, is difficult to detect. Its acoustic features have been discovered recently by using sophisticated digital recording tags (DTAG) developed by WHOI (Johnson et al., 2004; Zimmer et al., 2005), but traditional sub-surface detection devices have never been proven reliable. CIBRA developed a high quality wideband towed array with the purpose of detecting Cuvier’s beaked whales, and tested it in an area hosting a known population.File in questo prodotto:
