MARMAM readers.
We would like to call your attention to a paper recently published in
BioScience that considers modern approaches to assessing the effects of
noise on marine mammals in the Arctic. The full citation and abstract
are given below; .pdf copies are available on request.
Thank you,

Ragen, Robert Suydam, and Christopher Clark.

changing Arctic.BioScience 62, 289-295.
The recent loss of Arctic sea ice provides humans unprecedented access
to the region. Marine mammals rely on sound as a primary sensory
modality, and the noise associated with increasing human activities
offshore can interfere with vital life functions. Many coastal
communities rely on marine mammals for food and cultural identity, and
subsistence hunters have expressed strong concerns that underwater sound
from human activities negatively affects both the animals and hunting
success. Federal regulations require scientists and oil and gas
operators to acquire inci- dental harassment authorizations for
activities that may disturb marine mammals. Currently, authorization
requests are focused on the impacts of sound from activities considered
in isolation of one another, and this precludes any possibility of a
meaningful analysis of the cumulative impacts from multiple sources. We
propose a new assessment framework that is based on the acoustic
habitats that constitute the aggregate sound field from multiple
sources, compiled at spatial and temporal scales consistent with the
ecology of Arctic marine mammals.
