Thank you Walt, Dan and Oryoki for your advice- 

Sorry for the belated response - been out of the office.  I'm new to 
capturing bioacoustics so any advice you provide is very valuable to 
me.

I'm mostly wondering what quality of recording I should attempt.  Do 
I need 24-bit?  96 KS/s?  

I'm certain my ears couldn't tell the difference but can the call 
detecting software?  Or will more faint calls be more discernable 
(given the gain is already at maximum)?  

The Sound Meter looks like it may be the best fit for my budget and 
needs. Does the plug in power sacrifice anything compared to phantom 
power mics?  

And I don't understand the impacts of not having a balanced mic 
system.  I would like to record one channel in the air and one 
channel underwater simultaneously.  Do I need a balanced system for 
that?

Thanks again for your help.  I appreciate your time and knowledge!
