This
site
presents
an
account
of
a
research
cruise
to
investigate
how
the
food
webs
in
different
oceanic
habitats
vary.
The
scientists
wanted
to
see
ocean
life
in
its
natural
environment
and
conduct
experiments
that
would
not
be
possible
in
the
laboratory.
They
looked
specifically
at
three
types
of
ocean
habitat:
the
open
ocean,
the
continental
shelf,
and
an
upwelling
area.
The
researchers
were
hoping

In
this
lesson
students
discover
how
growth
rates
of
corals
can
be
estimated
from
samples
collected
at
a
single
point
in
time.
Students
will
identify
and
briefly
explain
two
methods
for
estimating
the
age
of
hard
corals,
learn
how
oxygen
isotope
ratios
are
related
to
water
temperature,
and
interpret
data
on
oxygen
isotope
ratios
to
make
inferences
about
the
growth
rate
of
deep-sea
corals.

This
Classroom
Connectors
lesson
plan
teaches
students
about
ocean
movements
such
as
currents,
tides,
and
waves.
This
includes
types
of
currents,
Northern
and
Southern
Hemisphere
currents,
differences
between
salt
and
fresh
water,
trade
winds,
and
tsunamis.
The
site
provides
goals,
objectives,
an
outline,
time
required,
materials,
activities,
and

In
this
lesson,
students
will
investigate
hydrothermal
vents
to
see
how
the
chemistry
of
the
water
they
emit
provides
clues
to
the
location
of
the
vents.
They
should
be
able
to
describe
hydrothermal
vents
and
characterize
vent
plumes
in
terms
of
physical
and
chemical
properties;
describe
data
gathering
operations
in
which
a
towed
instrument
package
("tow-yo")
measures
conductivity,
temperature,
and

Since
the
Cold
War
ended,
scientists
have
been
documenting
environmental
contamination
due
to
nuclear
testing
by
the
former
Soviet
Union.
This
radio
broadcast
reports
on
scientists
who
are
following
the
trail
created
as
chemical
and
radioactive
contaminants
work
their
way
into
the
Arctic
food
chain.
The
radionuclides
are
being
used
as
tracers
which
can

This
activity
will
help
students
to
understand
that
ocean
water
is
sampled
for
chemicals
and
organisms.
The
sampling
device
must
gather
enough
water
for
conducting
all
the
tests,
the
depth
at
which
the
sample
was
gathered
must
be
accurately
known,
the
temperature
at
time
of
collection
must
be
known,
and
it
must
not
allow
contaminants
to
enter
as
it
is
being
brought
up
on
deck.
Students
will

This
classroom
activity
gives
students
a
close-up
look
at
a
deep
sea
vent
community.
Working
in
small
groups,
students
can
complete
this
Web
investigation
in
a
single
class
period.
The
printable
six-page
handout
includes
a
series
of
inquiry-based
questions
that
prompt
students
to
remember
what
they
already
know
about
deep
sea
vents
and
how
they
can
