36、 an endangered species.Attaching radio devices to it is difficult andvisual sightings are too unreliable to give real insight into its behavior.So biologists were delighted early this year when with the help ofthe Navy they were able to track a particular blue whale for 43 daysmonitoring its sounds.

37、This was possible because of the Navy s formerlytop-secret system of underwater listening devices spanning the oceans.Tracking whales is but one example of an exciting new world justopening to civilian scientists after the cold war as the Navy starts toshare and partly uncover its global network of

38、underwater listeningsystem built over the decades to track the ships of potential enemies.Earth scientists announced at a news conference recently that theyhad used the system for closely monitoring a deep-sea volcanic eruption（爆发）for the first time and that they plan similar studies.Otherscientists
