Learn More About the Soil Forming Factors - This web page was developed from information found in a USDA, Soil Conservation Service (Now, Natural Resources Conservation Service) publication, "Conserving Soil", which is now out of print. It discusses five important factors that influence the development of various types of soil.

NASA Goddard Earth & Space Science Education Project (GESSEP) - An assortment of Earth systems science investigations which meet nation science, mathematics,
and social studies standards. Many utilize remote sensing data and several specific investigations
deal directly with Landsat data. Use the "Investigation Titles" link to view the investigations.

Ocean Color From Space - For the first time, oceanographers now have
the ability to view the global distribution of
photosynthetic organisms in the world's
oceans from space. The observations made
from the Coastal Zone Color Scanner (CZCS),
a radiometer that operated on NASA's
Nimbus-7 satellite from 1978-1986, have
sparked a revolution in the way we think, about physical and biological processes in the sea. Using techniques principally developed at the University of Miami and Goddard Space Flight Centers, color images have
been produced which show the incredible variability that exists in the distribution and concentration of phytoplankton--microscopic, single-celled ocean plants that provide the
ultimate source of food for marine life. The CZCS global data sets lay the scientific foundations for new generations of
satellite ocean color sensors and have formed a cornerstone for international efforts to understand the ocean's role in the global carbon cycle.

Ocean Color Research in India - Dr. Neera Chaturvedi has been working on Ocean Color remote sensing in India. She has studied data from Landsat, the Indian Remote Sensing Satellite (IRS), and Nimbus 7's
Costal Zone Color Scanner (CZCS). Some of her work is listed at this web site.

Oceanography from the Space Shuttle - Oceanography from the Space Shuttle is a pictorial survey of oceanic phenomenon visible to the naked eye from space. Originally published in 1989, it is now out
of print and only available on this web site. Thumbnail images give a preview of each chapter's photographs.

Ozone and the Atmosphere - This web site discusses the chemical composition and evolution of Earth's atmosphere, focusing on the protective layer of ozone in the stratosphere. The destructive properties of
tropospheric ozone are also presented. Diagrams and animation sequences are used to visually depict the delicate structure of the ozone molecule and the chemical reactions involved in
its formation and destruction. Ozone destroying pollutants were first identified in 1973. Since that time there has been a considerable amount of controversy surrounding the subject of
ozone depletion. More than 20 years of ozone-related scientific studies, international meetings, and global industrial agreements are summarized in the last section of this site.
