Dear MARMAMers,

We are pleased to announce that Bio-Waves, Inc. and the Centre for Research
into Ecological and Environmental Modelling at the University of St.
Andrews will be conducting the “Analysis of Passive Acoustic Data &
Acoustic-Based Density Estimation” workshop at the 2015 Society for Marine
Mammology’s 21st Biennial Conference in San Francisco, CA!  This event will
be a two day workshop on Saturday December 12th and Sunday December 13th
the weekend prior to the SMM conference.  Due to limited space at the main
conference venue, it will be held nearby at the downtown SFSU campus (at
the Westfield San Francisco Center), which is within easy walking distance
of the Hilton.  This workshop set is intended to provide experience in
analysis of passive acoustic monitoring data and demonstrate methods for
estimating population density and abundance of marine mammals using these

The two workshop days are complementary and are designed to supplement one
another.  As such, participants are encouraged to register for both days;
however if an individual is experienced in one of subject areas, they are
allowed to register for only one of the two days offered.  Registering
prior to September 15th, 2015 allows participants to be eligible for the
early registration fee of US $160 for both days or US$80/day; beginning
September 16th, 2015 registration fees will increase to US$180 for both
days or US$90/day.  Participants are required to bring their own Windows
laptop for this workshop, specifically as PAMGuard does not support the Mac
operating system.  For Mac users wishing to participate in the distance
sampling workshop only, information relating to running the software is
available at http://distancesampling.org/distanceextras.html.  If you do
not have a Windows laptop available, please email workshop organizers who
may be able to provide a computer.

Space is limited so be sure to sign up early!  To register for this
workshop, visit the conference registration site at:



The University of St. Andrews and Bio-Waves, Inc. are partnering to conduct
two, one-day workshops at the 2015 Biennial Marine Mammal Conference.
These workshops are intended to demonstrate methods for estimating
population density and abundance using passive acoustic data.  The
workshops will provide training in methods for both passive acoustic data
analysis (day 1) and density and abundance estimation using passive
acoustic data (day 2).  The workshops are designed to be complementary, but
are offered as two separate workshops so that participants can opt to
attend one day only (should they already be familiar with the concepts from
the other day).  Participants will register for each course separately, but
are encouraged to attend both.

The workshops will include a practical case study that will be used to
provide hands-on experience with passive acoustic data analysis and density
estimation.  The first day of the workshop will be focused on passive
acoustic data collection and analysis and will include both lectures and
hands-on analysis exercises.   In the practical sessions, participants will
use PAMGuard (www.pamguard.org) to post-process acoustic data collected
during a line transect survey, learning how to obtain localizations to
individual sperm whales.  Participants will also learn how to obtain
measurements from echolocation clicks selected during post-processing
analysis.  The result of this exercise will consist of a dataset of
perpendicular distances to individual sperm whales that can then be used to
estimate density and abundance using Distance software.  Participants will
be taught how to format these data and import it into Distance.  The second
day of the workshop will include an overview of methods for estimating
density and abundance using passive acoustic data collected from both fixed
and towed hydrophone arrays.  Participants will analyze the sperm whale
dataset from day one using Distance and R software, and will generate
density and abundance estimates.  Any participants already familiar with
Distance will be able to conduct the same analyses in R, a statistical
software program.  Participants will leave the workshop with an
understanding of how to process passive acoustic data for density and
abundance estimation and how density and abundance can be estimated from
acoustic data.
