MARMAM,
I am re-sending this because it has not yet posted on MARMAM since I
sent it a week ago and I am leaving the country for 10 days. I'd like
to make sure it gets posted, so I am re-sending before I go. Our team
appreciates you making this information available to MARMAM subscribers.

All,
This summer, a series of experiments to study deep-diving cetaceans
was conducted in the Tongue of the Ocean, just off Andros Island in
the Bahamas. In addition to extensive photo-identification efforts,
specialized archival tags ("D-tags" from Woods Hole Oceanographic
Institution) were deployed on both Blainville's beaked whales
(Mesoplodon densirostris) and short-finned pilot whales (Globicephala
macrorhynchus) to determine baseline diving, foraging, and social
behavior. Using careful protocols and monitoring, controlled sound
exposures were used in two occassions to obtain detailed information
regarding the behavioral reactions of these species to both natural
and artificial sounds in the mid-frequency (1-10 kHz) band. The
initial results, while admittedly limited in several regards,
demonstrate that these kinds of established procedures can be applied
safely to deep-diving cetaceans using mid-frequency sounds and yield
detailed information about behavioral responses.
The BRS scientific team has prepared a short cruise report summary for
BRS-07 that is now publically available at:
<http://www.nmfs.noaa.gov/pr/acoustics/brs-07.htm> Please note that
this is not a peer-reviewed document and is not intended for
citation. It is simply a summary of the results of the first phase of
BRS at a relatively early stage of analysis. Additional analyses are
underway and results will be subjected to the scientific peer-review
process in due course. A complete cruise report will be available, on
request, at a later point. Anyone interested in the initial results
should contact the contributing scientists on the BRS team for
permission and direction regarding appropriate referencing of
information in the interim.
