Errata and Updates
This page lists important
corrections and significant updates to the
AMS Ocean Studies Textbook and Investigations Manual.
- On page 2A-6 of the Ocean
Studies Investigation 2A, in the paragraph following
reference is made
to the Current Earthquake Activity map that is accessed via the course
website. The U.S. Geological Survey recently updated this website (earthquake.usgs.gov/earthquakes/map/).
On the USGS website, follow directions until the world map is displayed. Then click on the Options icon at the upper right,
and then click on the "7 Days, All Magnitudes, Worldwide" button.
Among changes made to the USGS earthquake map:
- Circles now represent the locations of
earthquakes, rather than squares. In the Investigation, replace the
word “square” with “circle”.
- In the Optional section of Item 18,
delete the first sentence and replace it with the following: While at
this site, click on the help icon at the upper right
to reveal a menu list. Under Links, click on "About Earthquake Data", and then click on
"Significant EQ Archive". Then follow the Investigation Manual's instructions.
- On page 2A-7 of the Ocean
Studies Investigation 2A, in the paragraph preceding
reference is made
to the Current Volcanism Activity map that is accessed via the course
website. The Smithsonian Institution's National Museum of Natural History Global Volcanism Program recently updated this website
On the SI website, the central Google map being used may need to be changed in scale (upper left corner buttons) to display the world view.
The map displays red map-marker symbols to show the location of active volcanoes for the past week.
An archive tab below the map allows a search by volcano or by date to find other activity.
- Update to textbook Figures
5.10 and 5.12, and
Table 5.2: The March 2009 paper "Earth's Global Energy
Budget" by Kevin E. Trenberth, John T. Fasullo, and Jeffrey Kiehl in
the Bulletin of the American Meteorological Society
updated energy balance numbers based on new observations and analyses.
We will be using these new numbers in the Third Edition of our course
textbook. The following updated figures reflect this new research:
Please note that these numbers slightly modify the planetary albedo and
- Correction to Investigations Manual 8B,
page 8B-4: Question #8 should delete the "is" following the question
choices. It should read: "This [(is)(is
not)] consistent ..."
- Update to textbook Figures 12.7 and 12.8: These
figures were taken from the 1990 IPCC Assessment.
In recent years, the proxy climate data used to construct these graphs
has been questioned, and the scientific consensus is that they are no
longer accurate portrayals. The IPCC Fourth Assessment
report (2007) provides figures that will be used in the next textbook
edition, substituting for 12.7 and 12.8. We encourage you to examine
the following graphs:
of NH temperature variation during the last 1300 years
