Mike Castellini, Ph.D., "How would you know if you were
impacting a marine mammal? What would you
measure? What would a healthy population of marine
mammals look like?"
This talk will revolve around the concept that trying to
assess what is “normal” in a marine mammal is somewhat
difficult. The entire symposium this year deals with the
impacts of noise, contaminants, tourism, fishing, etc on
marine mammals. In this talk, we will explore the overall
idea that to measure an impact, you need to consider the
animals that are not being stressed and compare them to
those that are under stress. But, what do you measure? You
know that when you are stressed, your heart rate goes
up…would that work for marine mammals? Sometimes stress
hormones increase when you are sick or under pressure…how
would you measure those in marine mammals? We will
conclude with a suite of methods, questions and issues that
need to be considered in any study of the interactions of
humans, environment and marine mammals.
Mike received his PhD in marine
biology from Scripps Institution of Oceanography in 1981. He
has been a faculty member at the University of Alaska Fairbanks
since 1989, Science Director for the Alaska Sealife Center in
Seward, Alaska 1995-1999, Director of the Institute of Marine
Science at UAF from 2002-2005 and is currently the Associate Dean
for the School of Fisheries and Ocean Sciences. Mikes
research focuses on how marine mammals have adapted to life in the
sea. Ever since his graduate work in San Diego, he has studied
marine mammals around the world examining their biochemical,
physiological and behavioral adaptations for deep and long
duration diving, extended fasting, exercise physiology,
hydrodynamics and even sleeping patterns. In Alaska, his work has
extended into issues of population health (why are marine mammal
populations declining in some areas?), contaminant chemistry,
reproductive chemistry and digestive physiology. Mikes graduate
students work from Alaska to Antarctica on these issues. He
as written over 75 scientific papers on his work and is
involved in local, state and National panels and committees
dealing with policy issues related to marine mammals, ecosystem
management and agency oversights. Background

Chris
Clark, Ph.D.,
"Ocean Voices: The Acoustic Ecology of
the Great Whales"
The great whales produce
an amazing variety of sounds. The most obvious are male
reproductive displays, or songs, consisting of long, intense,
hierarchically organized and repeated patterns of notes. In
1971 Roger Payne and Doug Webb proposed that prior to the
advent of modern shipping the largest of all earth’s
creatures, blue and fin whales, might have communicated across
oceans. Through access to the US Navy’s Sound Surveillance
System (SOSUS), whales have been detected across ocean basins.
This acoustic telescope allows observations of singing whales
over large spatial and temporal scales commensurate with their
ecologies and ocean habitats. Songs of blue and fin whales are
infrasonic (<20Hz), and simple: well
designed for ultra-long-range communication and navigation
in the deep ocean. The sounds of bowhead, humpback and right
whales are audible and complex: well designed for short- to
mid-range communication in coastal water. Singing blue and fin
whales slalom from one bathymetric feature to the next: their
voices reflecting off continental shelves, seamounts and
islands. Cohorts of singers move as acoustic herds spread out
over areas of tens of thousand square miles. Singing occurs in
high latitudes and during summer months, often in association
with concentrations of food, and during periods of intense
feeding. Numbers and distributions of singers can now be
monitored on ocean scales once thought impossible.
Paradoxically, these opportunities to finally perceive the
lives of the great whales are slowly disappearing into the
rising tide of human-generated acoustic noise, which in many
areas in the Northern Hemisphere has reached chronic levels
that now compromise the whales’ basic abilities to hear and
communicate.
Dr.
Christopher W. Clark, is the Imogene Powers Johnson
Director of the Bioacoustics Research Program at the Cornell
Laboratory of Ornithology and Senior Scientist in the
Department of Neurobiology & Behavior. He
holds advanced degrees in electrical engineering (M.S.E.E.,
SUNY-Stony Brook, 1974) and biology (Ph.D., SUNY -Stony Brook,
1980). His doctoral research concentrated on acoustic
communication in southern right whales. In 1980, Dr.
Clark
became an NIH postdoctoral fellow and was later appointed
assistant professor at The Rockefeller University where he
conducted research on vocal learning in songbirds. He joined
the Cornell and the Laboratory of Ornithology in 1987.
Dr. Clark’s research concentrates on animal acoustic
communication with a particular focus on the development and
application of advanced acoustic methods for scientific
conservation of endangered species.
He leads the Bioacoustics Research Program in the
design, development and application of computer-based systems
for quantitative analysis of animal vocalizations, and
acoustic techniques to detect, recognize, classify, locate,
track and census free-ranging animals.
Through ongoing collaborations with
U.S.
and international colleagues Dr. Clark conducts integrated
research at a variety of spatial and temporal scales to
investigate the influence of ecological, environmental and
anthropogenic factors on animal acoustic behavior.
Area of expertise/research focus: Acoustic
communication in baleen whales. Impacts of anthropogenic
noise/sound on whale communication.
Chris was born and raised on the outer Cape
(Cape Cod, MA) and as a young boy and throughout all my
teenage years ran wild through its salt marshes (alive with
herring, squids, crabs, eel grass), swam in its kettle ponds,
ate from its tidal waters and drank from its fresh water lens.
In my family, I was always surrounded by singing and music.
From the age of nine I attended the Cathedral Choir School of
St. John the Divine in
New York City
, where I sang twice a day, every day for four years. It was
there that my ear was trained to listen and to do so
carefully. In high school from testing they told me I would
best either be a farmer or a physicist. I am neither, and none
the worse for it. While starting my first semester in medical
school in a bio-medical-engineering program, I met Roger and
Katy Payne and their young family. It was then at the age of
23 that I learned that one’s passion can also be one’s
vocation. The rest of the story is my life’s history; a
bountiful journey listening to the world and proclaiming to
all that this world’s life is magnificent beyond all words,
and deserving of our reverence in every breath we take.

Douglas DeMaster, Ph.D.,
"Future of the International Whaling Commission"
The International Convention for the Regulation of Whaling
(ICRW) is a treaty signed in 1946 to “provide for the proper
conservation of whale stocks and thus make possible the
orderly development of the whaling industry” (see www.iwcoffice.org).
The IWC manages thirteen species of great whales, and
its charge is to adopt regulations for the conservation and
utilization of whale resources by periodically amending the
Schedule, a document that is an integral part of the ICRW.
Amendments to the Schedule must (at least in theory) be
based on scientific findings, and require a three-fourths
majority of all who voted.
Any member government can “object” to any decision
within 90 days of that decision, and thus not be bound by it.
There are currently 78 member nations, which are almost
equally split between pro-commercial whaling and
anti-commercial whaling countries.
Because of the strong views held by many member
countries, debate at the IWC annual meetings is often filled
with rhetoric that is not helpful in moving the organization
forward. At this
point, the IWC appears to be at an impasse due to an inability
or unwillingness of countries to compromise.
Discussions regarding a system that would establish a
Revised Management Scheme (the set of rules and inspection
procedures that would govern commercial whaling should the
moratorium be lifted) have failed to produce any agreement and
are currently stalled. This
has resulted in a situation where some countries have
threatened to leave the IWC.
In recent years, the total number of large whales
hunted for commercial or scientific purposes is similar to the
number killed prior to the implementation of the moratorium.
Three international meetings were held in the past year
regarding the functionality of the IWC.
All occurred outside the auspices of the IWC.
Possible ways forward and their respective impacts on
the conservation of large whales will be discussed.
Dr.
DeMaster became Science and Research Director of the Alaska
Fisheries Science Center, NAOO in October 2001. Previously he served
as Director of the National Marine Mammal Laboratory (NMML),
leader of the NMML Cetacean Assessment and Ecology Program,
and head of the Marine Mammal Division at the Southwest
Fisheries Science Center. Dr. DeMaster is recognized as one of
the leading experts on marine mammal stock assessment and
marine mammal–fishery interactions. He has published more
than 58 peer-reviewed publications on marine mammals and an
additional 38 reports related to the population ecology of
marine mammals. In cooperation with other NOAA Fisheries
scientists, Dr. DeMaster helped develop the system under which
marine mammals are managed in the United States under the
Marine Mammal Protection Act. Since receiving his Ph.D. from
the University of Minnesota in 1978, he has been an active
member of the academic community. He was an Adjunct Professor
at the Scripps Institution of Oceanography, where he taught
courses on marine mammal biology and population dynamics.
Since 1994, Dr. DeMaster has been an Affiliate Professor at
the University of Washington's School of Marine Affairs. He
also served as President of the Society for Marine Mammalogy,
was Vice-Chair of the Scientific Committee of the
International Whaling Commission (IWC), and is currently
Chairman of the IWC Scientific Committee.

Rolf Gradinger, Ph.D., Likely
Impacts of Arctic Change on the Feeding Grounds of Arctic
Marine Mammals
Rolf Gradinger and Bodil Bluhm
Birds,
seals and whales are abundant in the cold ocean waters along
the coastline of
Alaska
. In the Arctic regions, sea ice is one of the unique
structuring features for the life in the ocean. It is used by
seals to rest and reproduce, and by polar bears to migrate and
hunt. However less recognition has been attributed to its
enormous role on the entire structure of the marine food web.
Recent changes in the sea ice cover of the
Arctic
produced public concern about its impacts on the arctic food
web that will go well beyond birds and marine mammals. Our
presentation will discuss three potential changes in the
Arctic food web and how such changes might indirectly impact
Arctic marine mammals.
Dr. Gradinger
is an Assistant Professor of Biological Oceanography, School of
Fisheries and Ocean Sciences, University of Alaska Fairbanks.
He believes it was his interest in the Arctic ecosystems, that
brought him to Fairbanks, Alaska. Rolf was born in Germany, where
he also studied biology at the universities in Mainz and Kiel.
At Kiel University he received his masters and PhD degrees.
Since receiving his PhD his main interest has been in Arctic sea ice
ecology, which he explored as Post-Doc and Assistant Professor
at two institutions in Germany. In 2001 his wife and he moved to
Alaska, where they are both working as polar ecologists at UAF.
Besides polar marine ecology he is interested in classical
music, birding, fishing and kayaking.
Rolf's areas
of expertise/research focus is on Arctic ocean ecology, sea ice
ecology of Polar waters and Arctic ocean biodiversity

Caroline Jezierski,
Alaska SeaLife Center (Graduate Research Associate) and
Lindblad Expeditions (Naturalist)
This talk will address the
impact of ecotourism on harbor seal behavior and whether
educational training can alter human behavior in order to
reduce disturbance to the seals.
Caroline
grew up in the Midwest where her love of nature began on
family camping trips. While pursuing her degree in Biology at
Gustavus Adolphus College, her desire for outdoor adventure
increased. She spent her summers as a white water raft guide
in Colorado and studied wildlife ecology and conservation in
Tanzania. After college, she moved to the west coast where she
began her career as a field biologist. Caroline spent two
years as a member of the AmeriCorps Watershed Stewards Project
conducting stream and watershed surveys and providing
educational outreach to local communities. For nearly a decade
she has worked as a field biologist for state and federal
agencies. Her “office” has ranged from the tundra of
Alaska to the national parks of Washington to the broad rivers
of Oregon and to the redwood forests of Northern California.
Although she has specialized in inland salmon fisheries, she
has also conducted research on birds, amphibians, and most
recently, marine mammals. In the winter of 2000, her love for
the sea was born while sailing as a deckhand for Lindblad
Expeditions. In 2004, Caroline returned to school to pursue a
Master’s Degree in Marine Biology at the University of
Alaska, Fairbanks. She is currently based in Seward, Alaska
working with the Alaska SeaLife Center; she is studying the
human impact on the harbor seals hauled out on glacial ice in
Kenai Fjords National Park. She also works as a naturalist for
Lindblad Expeditions in Southeast Alaska and Baja California.

Caitlin O'Connell-Rodwell,
Ph.D.,
Keynote Speaker, "Lessons
from elephant communication and society facilitate positive
relationships with people"
The
structure of African elephant society is primarily matriarchal
in nature, where dominant female elephants make decisions for
the herd as a whole with regard to safety, movements, resource
choices and affiliations. Bull elephants also rely on
the decision making ability of dominant individuals.
Communication is an important aspect of survival, influenced
by the ability to communicate over long distances and affected
by local environmental and social pressures. New
findings about elephant communication and social structure
will be reviewed and implications for elephant/human
interactions discussed.
Caitlin
O'Connell-Rodwell is a Research Associate at Stanford
University, in the Department of Otolaryngology, Head and Neck Surgery.
Her discoveries about elephant society and communication have
been published and reported in various periodicals, including Science,
Science News, Natural History, National Geographic, The
Economist, and Discover. She has appeared on
National Geographic, the BBC, PBS/Nature, and the Discovery
Channel. She has just published a book with Simon &
Schuster entitled The Elephant's Secret Sense.
O'Connell-Rodwell lives in
San Diego
, where she and her husband direct the nonprofit organization
Utopia Scientific (www.utopiascientific.org)
as well as the film company, Triple Helix Productions, both of
which promote elephant conservation, science education and
public health issues around the world.

Lorrie
Rea, Ph.D., "Steller
sea lions and the potential for human interactions –
entanglements, contaminants and fishing."
I am looking forward to talking to WhaleFest participants
about issues involved with Steller sea lion and human
interactions. Humans
and marine mammals utilize the same marine environment and
thus have the potential to interact in many ways, some of them
detrimental. Three general areas of discussion will be
environmental contaminants, entanglement of sea lions in
marine debris and fishing gear, and the potential for
competition with fisheries. I plan to present recent research
conducted by Alaska Department of Fish and Game and other
researchers on environmental contaminant burdens measured in
sea lions in
Alaska
and on the types and rates of visible entanglement of sea
lions surveyed in
Southeast Alaska
. I will also briefly outline avenues of research being
undertaken to try to determine what the potential is for
competition between foraging sea lions and human fishing
operations and how to distinguish if competition for food
resources might be having a detrimental impact on sea lion
populations.
Lorrie works for the Alaska
Department of Fish and Game Division
of Wildlife Conservation, Marine Mammals Section. She received her Doctor of Philosophy from the University of
Alaska, Fairbanks. Her
dissertation was titled “Prolonged fasting in Pinnipeds”
and was chaired by Dr. Michael A. Castellini.
She received her Master's of Science from the
University of California, Santa Cruz, California, studying the
changes in resting metabolic rate during long-term fasting in
northern elephant seal pups (Mirounga

Jooke Robbins, Ph.D., "Assessing human impacts on free-ranging large whales”
The
Gulf
of
Maine
is one of four
North Atlantic
humpback whale feeding stocks, and likely the one with the
greatest interaction with humans. Segments of this
population have a coastal distribution that overlaps areas of
high human use. Since the 1970s, this has provided
unprecedented opportunities for scientific research. At the
same time, this population has been the focus of a sizeable
eco-tourism industry and is vulnerable to commercial fisheries
interactions and vessel strikes. In this talk, I will
discuss the benefits and difficulties of assessing population
status and impacts in areas where whales and humans routinely
overlap.
Jooke
is a senior scientist at the
Provincetown
Center
for Coastal Studies and the director of its Humpback Whale
Studies Program. She
holds a Ph.D. in marine biology from the University of St.
Andrews, Scotland. Jooke
has studied humpback whales since 1995 and conducts collaborative research in the North Atlantic, the North
Pacific and the
South
Pacific
Oceans. She is a member
of the Atlantic Large Whale Take Reduction Team and the U.S.
Delegation to the Scientific Committee of the International
Whaling Commission. Her area of expertise and research focus
is large whale biology, population structure & dynamics
and human impacts.

Peter Ross, Ph.D., "Killer
Whales of the North Pacific: Sentinels of a Contaminated
Planet"
Dr. Ross is a
Research Scientist who specializes in the area of toxicology,
ecotoxicology, marine mammal sciences, immunotoxicology and
physiology. He has a particular interest in the study of
marine mammals, reflecting their i) vulnerability to health
effects related to contaminant exposure and ii) their utility
as indicators of ecosystem health. Dr Ross conducted studies
which helped to elucidate the role of environmental
contaminants in the virus-associated mass mortality among
harbour seals in northern Europe in 1988. Dr Ross demonstrated
that the transient killer whales of the North Pacific Ocean
were the most PCB-contaminated marine mammals of the world. He
continues to explore the links between contaminants, food
webs, and marine mammals, and is conducting research on
harbour seals, sea otters, killer whales and grizzly bears.
Dr. Ross, a
marine mammal toxicologist, is based at the Institute of Ocean
Sciences in Sidney, British Columbia Canada. He obtained his
PhD from the University of Utrecht in the Netherlands, having
defended his thesis in Dutch. Prior to that, he obtained his
MSc (Dalhousie University) and BSc (Trent University). He has
published over 75 scientific articles, but only a few poems.
He has lived in Victoria, on southern Vancouver Island, since
1996. He likes chocolate, beer and red wine, though not
necessarily in that order.
