Advance Prep (3 days)
Review the list of materials for the field study prior to the lesson, because there are several items that you must
supply.
Safety
Review the Field Study Guidelines before conducting the field study.
Background
This field study will begin with the study of sea surface temperatures off the east coast of the United States.
Then, you will analyze a volcanic eruption. Mount Pinatubo’s eruption in 1991 was one of the world’s largest
eruptions in the past 40 years. Located in the Philippines, the volcano introduced significant amounts of ash and
gases into the atmosphere, enough to cool the temperature of the entire earth slightly over a period of 3 years.
Part 1: What Do These Images Reveal?
Procedure
1. From the list of materials for this lesson, click the image titled Gulf Stream 1. The image may open in a variety
of programs. Use the application on your computer that best shows the image.
2. Determine what area you are viewing. Some images have an information legend and key included; others
may include geographic clues to the area shown. Look at the information included with the image. This is an
image of the ocean temperature near the Atlantic coast of the United States, including parts of the states from
North Carolina to New Jersey.
3. Note that each color in this image represents data. Notice the colors closer to and farther away from the
coastline. What trends do you see?

4. From the list of materials for this lesson, click the image titled Gulf Stream 2. Consider the two images of the
same general region, but further south along the coast. These images were taken several days apart in early
September of 1999. What are the substantial differences between them? The first image is prior to the onset
of Hurricane Dennis. The second was taken shortly after the hurricane.
Part 2: Analysis of Volcanic Eruptions
Procedure
1. Familiarize yourself with the location of Mount Pinatubo and the details of the eruption. Use the Internet.
Determine the longitude and latitude of the volcano.
2. From the list of materials for this lesson, click the image titled Mount Pinatubo 1. All images that you will open
for Mount Pinatubo were taken after the main eruption of the volcano. Copy or save the first image. Open it in
a program that allows you to zoom in on an image. For the rest of this exercise, it will be assumed that you
are using the Paint program that many computers have in the accessories folder. You may choose to use a
graphics program or other tool to accomplish the same tasks. For helpful tips on using Microsoft Paint to view
images, see Instructions for Using Paint to Analyze Images.
3. Compare the images and note how far the cloud traveled. To do this, note that the images have a longitude
and latitude grid where the distance between each pair of longitude or latitude lines represents 10°. Consider
that at different latitudes, 1° of longitude will not cover the same distance. At the latitude that you will note for
the volcano, the circle of latitude (the east-west line that circles the earth) has a length that is 96.6% of the
earth’s circumference (the earth’s circle of latitude at the equator), which is about 40,075 km. Since there are
360° of longitude, each degree of longitude is equal to the length of the circle of latitude at that point divided
by 360. For the circle of latitude that passes through the volcano, each degree if longitude is equal to 108 km.
4. Now that you have determined this scale, find the center of the cloud as best you can. Note what you
consider the latitude and longitude of the center of the cloud. There will be variance between the location you
choose as the center and what others may choose. Additionally, remember that each pixel is not a point but
rather a large square that covers a significant area.
5. Repeat this procedure for the other satellite images, Mount Pinatubo 2 and Mount Pinatubo 3. Since the cloud
seems to be getting larger, it may be more difficult to determine its center, but use a point that is in the center
of the white area on the image. These images do not have a grid as the first one did, so you will have to
estimate the latitude and longitude to the nearest degree. Record your results in the table.
6. Calculate the distance that the center of the cloud traveled from Mount Pinatubo. Assume that the distance
north and south is negligible compared to the distance to the east and west. This can be calculated easily by
determining the number of degrees longitude the center of the cloud moved and multiplying the result by
108 km, the number of kilometers in a degree.

Part 3: Closer to Home
Procedure
1. Download and install Google Earth. Use the Instructions for Downloading Google Earth to help with the
process.
2. Note that Google Earth will allow you to view the location where you live in detail. Perform an analysis of the
different types of land usage that are exhibited. To do this, find an image that is centered on your residence
and save it somewhere you will be able to find it easily.
3. Open and zoom in on the image until it is pixilated. Microsoft Paint is a valuable tool for this, though you may
use another graphics program for this analysis. For helpful tips on using Microsoft Paint to view images, see
Instructions for Using Paint to Analyze Images. For your analysis, indicate the size of the area that you chose
to use (for example, 250 pixels × 200 pixels).
4. Determine the types of land usage in the image. Common land types are vegetation, roads, streams, and
buildings. Feel free to include others as you need to.
5. Determine the actual area of a pixel in square meters.
6. Determine the percentage for each land type in your region.

Field Study – Remote Sensing 1
Remote sensing is an important way that scientists obtain data about the
environment.
Remote sensing has made huge amounts of new environmental data available to
contemporary science. Often it is useful to represent the data both in mathematical form,
as in tables, and in image form, as in photos or maps. In this field study, you’ll analyze
remotely sensed data in image form. Then, you’ll compare remote sensing with other
ways of acquiring and analyzing the data. Finally, you’ll communicate your results.
Environmental science relies on remote sensing.
Ecologists, climatologists, and others who study environmental issues rely on data to draw
conclusions. While some data are taken locally, most are taken remotely. Why?
Dan Franck, a senior content specialist with K12, and Pat Keeney, a senior instructional
designer and former NASA consultant, answer that very question: Why is remote sensing
important to environmental science?

Click What Is Remote Sensing and Why Is It Important? to see Dan Franck, a senior content
specialist, and Pat Keeney, a senior instructional designer and former NASA consultant,
discuss why remote sensing is important to environmental science.
The electromagnetic spectrum is a key element in understanding remote sensing.
The electromagnetic spectrum of energy illustrates a wide array of types of energy.
Remote sensing devices detect and record small parts of this spectrum and provide
images that can be easily interpreted.
Each part of the spectrum tells different things about a region or object, just as visible light
and X-ray views of your body give information about you on the outside and inside.
GAMMA RAYS:
wavelength: 10-6 to 10-2 nm
X RAYS
wavelength: 10-2 to 10 nm
UV RAYS
wavelength: 10 to 400 nm
Visible Lights
wavelength: 400 to 700 nm
Infrared Waver
wavelength: 1,000 nm to 1 mm
Microwaves
wavelength: 1 mm to 10 cm
Radio Waves
wavelength: 10 cm to 10 km
In many ways, remote sensing is superior to other ways of collecting data.
Remote sensing is used for many different purposes. To get a sense of how and where
remote sensing is used, view Dan Franck and Pat Keeney giving several examples of
remote sensing.

Click Remote Sensing in Different Parts of the Electromagnetic Spectrum to see Dan
Franck, a senior content specialist, and Pat Keeney, a senior instructional designer and
former NASA consultant, discuss the electromagnetic spectrum and how it is used in
environmental science.
Counting the number of pixels of a color range helps determine the amount of a
variable.
This image was taken when Mount Pinatubo erupted in 1991. If you look carefully, you will
see blocks of color, or pixels. Each pixel represents an amount of something—in this case,
sulfur dioxide in the atmosphere. You could count the pixels of each color, use the scale
given to interpret each as an amount of sulfur dioxide, add them all up, and determine the
total amount of sulfur dioxide given off by the volcano.
The blocks of color, or pixels, represent an amount of something—in this case, sulfur dioxide in the
atmosphere.
