Estuaries
are
partially
enclosed
bodies
of
water
along
coastlines
where
fresh
water
and
salt
water
meet
and
mix.
They
act
as
a
transition
zone
between
oceans
and
continents.
This
site
examines
various
aspects
of
estuaries,
focusing
on
the
geological
features
that
make
an
estuary,
as
well
as
the
water
circulation
patterns
by
which
they
are
classified.
It
also
has
a
section
that
allows
the
user
to

This lesson is designed to help students gain knowledge in graphing a microset of data, then using the graphs to investigate the relationship between volcanic activity and the presence of atmospheric aerosols. The lesson provides detailed procedure, related links and sample graphs, follow-up questions and extensions, and Teacher Notes.

This resource ties together physical and biological aspects of ocean color for high school students. Specific sections discuss life in the oceans, the appearance of the ocean from space, phytoplankton (the little link in a big food chain), carbon (where does it go?), and the Earth as a giant greenhouse. There are also activities that accompany these lessons.

Estuaries
have
physical
traits,
and
scientists
use
a
variety
of
measurements
such
as
water
depth,
salinity,
and
current
speed
to
describe
an
estuary.
This
site
describes
the
various
measurements
that
make
up
the
physical
properties
of
an
estuary,
using
Narragansett
Bay
as
an
example.
Specific
sections
of
