This folder contains images and descriptive text from the NOAA Paleoclimatology Educational Slide Sets.
  
The images are presented in .jpg or .gif format, and also as .tiff scanner files of the original 35mm slides.
The .tiff format files have been compressed using pkzip, and the resulting compressed files are also 
available here, and have the file name extension .zip.  The accompanying text files describe each image, 
and collectively provide a description of some of the major proxy data types utilized in paleoclimatology, 
how the data are collected and analyzed, and summarize paleoclimate information which can be deduced 
from these proxy data.   


The Ice Ages

Scientific Authorship:
Thomas G. Andrews

The quest to understand the cause of the Pleistocene ice ages is a fascinating example of how scientists 
have used different types of evidence to understand earth processes. This slide set traces history of 
investigation of the ice ages, from the discovery of glacial erratics and moraines in the 1800s, 
and the theories of orbital variations in solar radiation, to recent investigations of the glacial-interglacial 
cycles using evidence found in ice cores and deep sea sediments. This slide emphasizes how different types 
of geologic evidence can be used to understand how earth climate has varied in the past. The set includes 
photos of evidence of glaciers, pictures and graphs from ice cores and marine sediment cores, 
and pictures illustrating changes in the earth's orbit. Accompanied by a comprehensive narrative. 
Appropriate for college-level audiences.
