Dear colleagues,



Please note the extended abstract deadline for a session on polar
soundscapes at POLAR2018:


 ‘The acoustic environment of the polar oceans: exploring polar
soundscapes’ at the upcoming POLAR 2018, A SCAR & IASC Conference in Davos,
Switzerland from 19-23 June, 2018. See http://www.polar2018.org/


The new deadline is:

*12 November 2017, 6pm CET*



The goal of POLAR2018 is to bring together excellent research from both
poles, as well as from high altitude areas, focusing on the similar
challenges those regions face. The program features 65 sessions, structured
into 12 categories spanning topics from oceans and sea ice, cryosphere,
atmosphere and climate, geology and geophysics to biology, ecology and
more.



Please consider submitting an abstract for the Polar Soundscape session
outlined below.



We hope to see you in Davos!

Best Regards,



Ilse Van Opzeeland (Alfred-Wegener Institute, Bremerhaven, Germany)

Karolin Thomisch (Alfred-Wegener Institute, Bremerhaven, Germany)

*Session Title*

The acoustic environment of the polar oceans: exploring polar soundscapes



*Session Description*

The underwater acoustic environment is created by the superposition of
sounds from a multitude of sources of natural biotic and abiotic as well as
anthropogenic origin. For aquatic life, marine mammals in particular, their
perceived soundscape directly impacts their ability to hunt, communicate
and possibly navigate these waters. However, for much of the world oceans,
and for polar seas in particular, little is known about the diversity of
contributions and the dial and seasonal patterns as well as long-term
trends of the acoustic environment. This lack of knowledge hampers our
ability to predict how anthropogenic change will impact on populations to
which these waters form an essential habitat. The impact of anthropogenic
activities on the acoustic environment may be direct, by adding noise, or
indirect through global climate change, affecting acoustic propagation
conditions and habitat usage. To outline the range of polar acoustic
environments and the nature of their main contributories, this session aims
at bringing together studies addressing these issues through in-situ
recordings, methodological advances and numerical modeling.
