I've looked at all the usual sources for blue whale acoustic info and
couldn't find any definitive statement that told the upper limits of the
range of blue whale communications. I have heard that blue whale calls,
being the loudest sounds made by any animal, can carry for over 1,000 miles
using the SOFAR channels, in fact from Bermuda to the UK.
Your best source for information on the range of blue whale vocalizations
would be Dr. Christopher Clark of Cornell Univ. I wasn't able to find a
direct email address for him, but the following should help you contact him.
Bioacoustics Research Program
Cornell Laboratory of Ornithology
Other studies that might help would be:
Stafford, K.M., Fox, C.G., Clark, D.S. (1998). Long-range
acoustic detection and localization of blue whale
calls in the northeast Pacific Ocean. J. Acoust. Soc.
Cummings, W.C., Thompson, P.O. (1971). Underwater
sounds from the blue whale. J. Acoust. Soc. Am.
