REMOTE SENSING THE 5 SENSES ENHANCED
WE WORK USING OUR FIVE SENSES TO TELL US ABOUT THE EARTH • Sight – observing a volcanic eruption • Hearing – sounds of a rockslide • Touch – pumice vs obsidian • Taste – salt • Smell – swamps • HOW DO WE USE THESE IN A REMOTE WAY – SENSING FROM FAR AWAY?

1. TASTE AND SMELL – MOUTH AND NOSE • Taste and smell are combined because they use chemoreceptors • Chemo – chemical; Receptors – receivers • These 2 senses are combined to determine good versus bad • Example – Spoiled Milk or Memory Triggers This Photo by Unknown Author is licensed under CC BY-SA-NC
1. TASTE AND SMELL – MASS SPECTROMETER • In geology we use what's called a Mass Spectrometer • Acts like a nose when drilling • Very sensitive to chemicals in the air – AKA Very accurate Chemoreceptors • These sensors allow us to detect helium, CO2, Nitrogen, and other elements
Remote Sensing - The 5 Senses Enhanced
1. TASTE AND SMELL – MASS SPECTROMETER • It can smell small changes in water, soil, etc. • How long it takes for a body to use medicine • Trace evidence for detectives • Many applications to smell things our noses can’t This Photo by Unknown Author is licensed under CC BY-SA
1. SIGHT – OUR EYES • Once the light is in our eye it passes through fluids • The light lands on the retina at the back of the eye • The retina turns the light rays into signals that our brain can understand • The retina uses light sensitive cells called rods and cones to see This Photo by Unknown Author is licensed under CC BY-SA
1. SIGHT - CAMERAS • The lens is a glass plate that covers the opening to the camera body • The lens directs from an object to the film when the shutter opens • When you push the button on a camera, it opens a shutter, which is a lid that protects the film • The shutter is like your eyelids, and when you open them, then the light comes in This Photo by Unknown Author is licensed under CC BY
1. SIGHT – CAMERAS ON DRONES, ROVERS, SATELLITES • Cameras mounted on a remote controlled drone • Cameras also sent to space • On satellites and rovers and probes sent to other planets • We can see beyond what our eyes can see through remotely sensing sight This Photo by Unknown Author is licensed under CC BY-SA
1. SIGHT – INCLUDES INFRARED, NIGHT VISION, ZOOMS • Plants • Fire • Lost people • Diseases / bugs
1. HEARING – OUR EARS • The inner ear is shaped like a snail and is called the cochlea • Inside the cochlea, there are thousands of tiny hair cells • Hair cells change the vibrations into electrical signals that are sent to the brain through the hearing nerve • The brain tells you that you are hearing a sound and what kind of sound it is This Photo by Unknown Author is licensed under CC BY-SA-NC
1. HEARING – SEISMIC • Electric vibrators or falling weights drop on the ground making a sound • The sound waves are reflected off of different layers underground • Measuring the time for the waves to get to a receiver (ear) • Tells us what is underground
1. HEARING - SEISMIC • We use the listening trucks or geophones to measure along a line • Going back and forth on many lines makes a picture that we can see • This picture shows us what is underground
1. HEARING - SEISMIC
1. TOUCH – OUR FINGERS AND HANDS • Tell if something is hot or cold • Dull or sharp • Rough or smooth • Receptors on your skin or nerves This Photo by Unknown Author is licensed under CC BY-SA
1. TOUCH – WIRELINE LOGS • Temperature – hot or cold • Type of fluid in rock (water or oil) • Type of rock (lithology) and rock quality (porosity/permeability) • Cracks or broken • Touches the rock using different sensors at depth
Permeability? What Fluid? Type of Rock? Porosity?
THE END – ANY QUESTIONS?
