directional microphones

[van Polanen Tamara <>]

Dear Bioacousticians,
 
 I was wondering if anyone may be able to help me.  I
 am intereted in directional microphones as a way of
 picking up seal vocalisation down in Antarctica. 
 Basically I would like to tune in to particular sounds
 from a distance and though that may be possible with a
 directional microphone.  I could then tape the sound
 onto a DAT recorder.  Could anyone suggest a good
 system.
 
 Thankyou
 
 Tamara
