II. Studying
effectively
Selected Excerpts from Course Introduction:
Clicking on
web links is "optional" but they will help illustrate
points made in lecture and by the author of MLATS
The web is
very visual, links will help you visualize
Certain plants
or animals will be a Featured Organism
Certain places
of special interest are a Featured Locality
Each chapter
starts with an interesting Case History (read
it)
Review questions
will be interjected in notes (RQ)

8 ocean zones?
RQ1.4:
What are some generalities that can be used to
characterize each?

Note important definitions of
plankton, nekton,
and benthic organisms
In lecture I emphasized the life
cycle of a sea
urchin

RQ1.11:
Order these in the order they occur in time:
a) barrier reef; b) atoll; c) fringing reef
Charles
Darwin is rightfully the most famous biologist
but he
also made extremely important contributions in geology
including
his publication
of a theory on how
coral atolls form
RQ1.12: Where is the ocean the most productive, and why?
Cool current images from space of
primary
productivity in the sea
Seafloor map of Monterey Bay Submarine Canyon
Monterey
Bay Aquarium's
Mysteries
of the Deep On-line Exhibit
RQ1.13:
Why do deepsea mountains have a "snow line"?
RQ1.14:
If a foram skeleton drifting downward would
take 400 days, by itself, to sink a typical ocean
depth of 4 km, how do they often make it to the
bottom much faster?
RQ1.15: What are deep sea organisms feeding on?
Featured Organism p. 15 (see p. 142-143):
foram,
Globigerina
Featured Organism p. 15 (see p. 114, Tab. 5.1):

V. Planetary Features that affect Ocean Life
Divide the ocean by:
Proximity (closeness) to shore (neritic vs. oceanic)
Depth
(epi-
meso- bathy-
abysso-
or hadopelagic)
Seafloor
zones (supralittoral or "splash" zone, intertidal,
sublittoral or "subtidal", bathyal zone, abyssal zone,
hadal)
RQ1.16: What does "deep sea" refer to?
Earth tilt regions: 23.5°N to 23.5°S = tropics,
23.5 to 66.5° N or S = temperate;
66.5° to 90° N or S = polar)
Latitude regions: low, mid, high (30° latitude division)
RQ1.17:
Where is Fullerton with respect to these last two
divisions? How often (if ever) is the sun directly
overhead in Fullerton? Why is the daylength =
nightlength everwhere on earth about March 21 and
September 21?
RQ1.18: Where was "southern California" 65 mya, relative
to the place presently at this same latitude and longitude
on Earth today? How about 150 mya?
