Internet Problem 6: Marine Life
This Internet Problem deals with the relationship between marine Cetaceans and the trophic level at
which they feed within the marine food web. You are asked to compare the seasonal migrations of
three species of Cetaceans with the satellite seasonal global primary productions maps and draw some
conclusion, based on what you have learned reading the text and Instructor’s Notes, as to how seasonal
global primary production patterns related (or do not relate to) to the migration patterns of the three
specific Cetaceans you have chosen to study.
Go to: NOAA Fisheries Office of Protected Resources
http://www.nmfs.noaa.gov/pr/species/mammals/cetaceans/
1) What are marine Cetaceans?
2) Choose three marine Cetacean species (preferably migrating species) from the list at the NOAA
Fisheries Office of Protected Resources web page:
1)
2)
3)
3) In the chart for question 5 below, enter the name of the species that you have chosen, and
briefly describe the seasonal migration patterns for each species. If there is not enough
information about migrations patterns at the NOAA website, you should search elsewhere.
4) To answer the remaining questions go to Global Primary Productivity Maps at:
http://www.nature.com/scitable/knowledge/library/the-biological-productivity-of-the-ocean70631104
Scroll down at this webpage to Figure 4. The top two images show chlorophyll concentrations
for July/August/September (summer – Fall in the northern hemisphere) and January/ February/
March (Winter in the northern hemisphere.)
Note: If you are having problems accessing this website the seasonal primary production
maps needed to complete this assignment are available at the bottom of this assignment.
Or you may go to the following website and page through the monthly Primary Productivity
maps for January –December 2014. In these displays the color scales is more muted. The light
areas are area of high productivity and the darker blue area are areas of low productivity.

4a) How are these seasonal primary production maps constructed (what data is used)?
Note: for more about how the primary production maps are constructed, go to:
http://www.science.oregonstate.edu/ocean.productivity/
or
http://neo.sci.gsfc.nasa.gov/view.php?datasetId=MY1DMM_CHLORA&year=2014
4b) What is seasonal primary productivity?
Also read the Chapter 9 Essay: – Ocean Color and Marine Productivity
5) Compare the seasonal primary productivity maps with the information you have about each
cetacean species’ seasonal migration patterns. Are they related? Complete the chart below and
draw some conclusions about how each species’ seasonal migration pattern is controlled by the
season zones of high productivity. The key here is to understand the species and at what
trophic level they feed.
Name of Species 1:
Seasonal Migration Adaptation:
Describe the relationship of this migration
pattern to the global primary productivity
maps:
Name of Species 2:
Seasonal Migration Adaptation:
Describe the relationship of this migration
pattern to the global primary productivity

Name of Species 3:
Seasonal Migration Adaptation:
Describe the relationship of this migration
pattern to the global primary productivity
