ultrasonic recording question

[Anna Hall <>]

Dear Colleagues,

I am preparing to record wild harbour and Dall's porpoise (~2kHz - 150kHz) and 
am looking for advice on recording from a hydrophone directly to a laptop 
computer while at sea.

Does anyone have any advice regarding an appropriate setup - or recommend a 
particular equipment (laptop/sound card etc) that has worked well with 
recording and analyzing ultrasonic echolocation?

I've found many references to terrestrial vertebrates, but fewer that deal with 
the technicalities of recording ultrasonics in the marine environment.

Thank you for any advice,
