• Named “elephant” because the
nose of and adult male resembles
an elephant’s trunk
• Found in the North Pacific
• During breeding they live on
beaches, rest of the year off shore
• Young pups nurse about 28 days
and gain about 10 pounds a day
• Adult male may reach 13 feet
• Can stay under water for up to 2 hours at a time
• Eat deep-water, bottom-dwelling marine animals such as ratfish, swell
sharks, spiny dogfish, eels, rockfish, and squid
• were hunted to the brink of extinction, primarily for their blubber,
which was used for lamp oil
• For more info see links in Chapter 1 “Northern Elephant Seals”
Someone who uses the process
of science to find answers about
how and why things work in
the world and in the observable
universe.
Science is not just facts
Science is the way we analyze
the facts




We know very little in
the big scheme of
things
There are depths that
we are still unable to
measure
Life that we have not
seen, species that have
yet to be discovered
Resources that are still
unknown
Bathynomus giganteus

Chapter 1 “Deep sea
creatures”



Oceans influence the weather and world climate
patterns which dictate how warm, cold, wet, or
dry a region will be
Oceans determines
where organisms live
Oceans provide important
resources (food, oxygen,
and natural resources
such as oil).



Commercial fishing has severely depleted many
types of fish
Pollution has deteriorated many marine
environments.
Coral reefs and
mangroves are
dying off
in record
numbers



Process of discovering
facts, processes, and
unifying principles that
explain the nature of the
oceans and their
associated life forms.
Oceanography is the
science of recording and
describing the ocean’s
contents and processes
1.
Biological oceanography (marine biology)
studies the diversity of life in the ocean and the
oceans role as their habitat
2.
Chemical oceanography
studies the chemistry of the
seawater. Examines chemical
changes brought about by
nature and people.
3.
Geological oceanography is the study of the
geology of the ocean. This examines the
composition of marine sediments and rocks.
Studies underwater volcanoes, seabed
movement, earthquakes
Molokini crater in
Hawaii
For more info see links
in Chapter 1
“Underwater
volcanoes”
4.
Physical Oceanography is the study of physics
in the marine environment. This examines
water movement such as waves, currents and
tides.



Studying marine science combines traditional
science concepts to marine science concepts
Integrated different fields of science allows an
individual to understand that many branches of
science are interconnected.
Marine science works closely with the physical
sciences (chemistry/ physics), life sciences
(biology, physiology and ecology) and Earth and
space science ( study of the physical earth, and the
universe)




Science as inquiry- way to
solve problems
Science and technology- how
science and technology work
hand in hand with each other
Science in personal and social
perspectives- how science
affects you and society
Historical nature of sciencehow science evolved as a
discipline
A body of knowledge
and organized method
used to gain knowledge
about the observable
universe.
Is a material system that produces results



What are some examples of
technology?
How do we come up with
technology?
What are some early examples
of technology?



Is all technology good?
What are some downsides
or negative effects of
technology?
If you were top scientists
how would you argue for
technology that negatively
affects nature? Now argue
against current technology
that affects nature
negatively.

1. Disregard (ignore) the effects of
technology


2. Dismiss the effects of technology
(not agree with scientists)


humans go extinct
humans go extinct
3. Prioritize developing
technologies that positively affect
the environment

we live
This should be review for everyone. Write the 5 steps
below. If you need to review these 5 steps re-read pages
1-24 through 1-28 for a detailed explanation of each

Identify the problem ( or questions)
Make a hypothesis (educated guess)
Test the hypothesis
Interpret and analyze the results
Report results, procedures and conclusions
Inductive/ deductive reasoning should take place
during step 2 of the scientific method


Use inductive reasoning to propose a process
that explains the facts you observed
Use deductive reasoning to propose what you
would observe should a known process take
place
Observe a
fact (F)
Inductive (I)
reasoning
Bubbles in
the water
Inductive

Propose a
process (P) that
explains the fact
Scuba diver in

Propose
what should
be observed
Scuba diver


Always changing
Remember some scientist thought the earth was
flat and we just fell off the edge if we got too close
to the edge
Not all theories are correct
Scientist thought earth was the center of the
universe for centuries





Scientists need to stay current on advances and
current theories
Staying current can help society come to
understand either positive or negative effects
Example would be human cloning
Twins are human clones,
Not all what the media writes is the most current
based on the scientific theories currently
presented
