As
part
of
the
Water
Institute's WaterTalks lecture
series,
Jay
Austin,
professor
and
department head
in
the
Department
of
Physics
and
Astronomy
at
University
of
Minnesota
Duluth,
presents,
"Winter
Conditions,
Ice,
and
Climate
Change
on
Lake
Superior."
Light
refreshments
will
be
provided.

information
Winter
conditions
in
general,
and
ice
characteristics
specifically,
on
large
lakes
are
poorly
understood
relative
to
summer
conditions.
However,
on
Lake
Superior
and
other
ice-forming
lakes,
winter
conditions
play
a
significant
role
in
determining
the
properties
of
the
lake
throughout
the
year.
In
this
presentation,
Prof.
Austin
will
discuss
some
of
the
recent
progress
on
understanding
how
a
deep,
mid-latitude
freshwater
lake
like
Lake
Superior
behaves
in
the
winter,
how
it
is
(and
isn’t)
different
from
behaviour
of
smaller
lakes,
direct
measurement
of
some
properties
of
the
ice
field,
and
implications
for
the
lake
throughout
the
subsequent
year.
Speaker
bio
Jay
Austin
is
professor
and
Department
Head
in
the
Department
of
Physics
and
Astronomy
and
holds
a
joint
appointment
at
the
Large
Lakes
Observatory.
He
has
been
at
UMD
since
2005.
He
received
his
BS
degrees
from
Cal
Poly,
San
Luis
Obispo
in
Physics
and
Mathematics,
and
received
a
PhD
in
Physical
Oceanography,
jointly
awarded
by
the
Woods
Hole
Oceanographic
Institution
and
the
Massachusetts
Institute
of
Technology
in
1999.
His
research
interests
are
diverse,
drawing
on
the
rich
array
of
physical
phenomena
in
large
lakes.
His
initial
work
at
UMD
dealt
with
the
response
of
large
lakes
to
climate
change,
work
that
persists
to
this
day.
In
addition,
he
is
interested
in
wind-driven
circulation,
ecological
acoustics,
and
the
role
of
ice
on
large
lakes,
among
other
topics.
He
is
primarily
an
observationalist,
spending
time
in
the
field,
on
boats,
collecting
novel
data,
and
bringing
oceanographic
techniques
to
the
field
of
lake
studies.
Support
for
his
work
has
come
primarily
from
the
National
Science
Foundation
and
the
National
Oceanic
and
Atmospheric
Administration.
