MARMAM subscribers,
We are pleased to announce the publication of a new paper regarding new
technologies and the evolution of experimental methods in the first two
years of the Southern California Behavioral Response Study (SOCAL-BRS).
The reference, abstract, and where to acquire the article are given
below. We would also like to remind MARMAM subscribers that additional
information regarding the SOCAL-BRS project is available at
www.socal-brs.org and that our from-the-field blog will resume around 10
October at: http://sea-inc.net/blog/.

ABSTRACT: Behavioral response studies (BRS) are increasingly being
conducted to better understand basic behavioral patterns in marine
animals and how underwater sounds, including from human sources, can
affect them. These studies are being enabled and enhanced by advances in
both acoustic sensing and transmission technologies. In the design of a
5-year project in southern California (" SOCAL-BRS), the development of
a compact, hand-deployable, ship-powered, 15-element vertical line array
sound source enabled a fundamental change in overall project
configuration from earlier efforts. The reduced size and power
requirements of the sound source, which achieved relatively high output
levels and directivity characteristics specified in the experimental
design, enabled the use of substantially smaller research vessels. This
size reduction favored a decentralization of field effort, with greater
emphasis on mobile small boat operations capable of covering large areas
to locate and tag marine mammals. These changes in configuration
directly contributed to significant increases in tagging focal animals
and conducting sound exposure experiments. During field experiments,
received sound levels on tagged animals of several different species
were within specified target ranges, demonstrating the efficacy of these
new solutions to challenging field research problems.

The world's seafloor for which we have first-hand accounts, detailed
maps, and samples remains minuscule, new vehicles, instrumentation, and
strategies will be needed to shape our current and future exploration
programs. This issue presents a number of papers that illuminate
different aspects of ocean exploration.
