## Geologic Hyperspectral Remote Sensing

Shapiro, Ford, Capehart Linear algebra, radiation transfer, image processing, programming
• Deriving U and V components from radial doppler [relocates?]
• Pythagorean theorum, total derivative
• low order modeling (parameter simplification), least square error
• Mean seasonal/annual temps to demonstrate e at the lapse rates same j - latitude
• derivatives, statistics, map skills
• Pressure gradients across [cyclones, hurricanes - drawn with symbols]
• derivatives, maps
• Representing atmospheric stability
• derivative, data, graphical representations
• Elevation maps, derivatives, lifting condensation
• Deriving the equation of motion from F=ma
• Total derivatives, expansion, partial derivatives
• Point measurements—geospatial statistics
• Coriolis force
• Angular velocity W = 1 rotation / 24 hours = 7.28 x 10-5 s-1
• Fun with playground apparatus (bully skills)
• Spherical coordinates f=2 W sin j
• Scale analysis (cyclone vs. bathroom plumbing)

## Topographic maps / level curves

• max/min
• directional derivative
• vertical exaggeration in profiles

## Stress-Strain Relationships: Structural Geology

Context:
• Rock undergoes deformation
• Kinematics and dynamics: kinematics—displacement; dynamics—forces
• Flow field
• Deformation conceptual models linked to field evidence
• Uncertainty in understanding geologic events—deep time
• GPS—how to work into geology?
• Field data for location—mapping
• Measurements of displacement—human time scale

## Periodicity in Geologic phenomena

• tide tables
• sea level changes
• summaries of sinusoids: |A|, w, f
• varies
• heat flow evidence for mantle convection (spatial periodicity)
• land forms in compressional terrain
• common statistical distributions observed in geologic phenomena
• log-normal - poisson - 1/f

## Ideas for Quantitative Geoscience Applications

• Morphometric Analysis of fossils
• compare consistent feature for growth and population studies, ex.: length/width
• Seismic Modeling—Ray Dath Analysis (see diagram on poster)
• Earth's circumfrance using stick and shadow ratio at different latitudes
• Use fluid mechanics to find bulge at equator
• Locating Earth's core based on seismic evidence

### Slope stability Vectors and gradients Radioactive decay Exponential functions (DE) Density of crust, mantle, core Volume of sphere Groundwater flow net Gradients 3D Gravity anomalies Manipulating equations, inverse square law Basin subsidence Lines; smoothing piecewise function Porosity of RX Ratios; regression Groundwater containment Contours and level curves Modeling

1. Estimating the amount of shadow an addition to a house would add to a neighbor's lawn
2. Analyzing flood information related to time and discharge
3. Analyzing sediment size based on water velocity
4. Predicting flood crests based on rainfall and characteristics of water basins
5. Estimating erosion from sediment removed based on area covered and frequency of storms
6. Predicting what will happen to an ice shelf by looking at the temperature gradient vertically through the shelf.
7. Predicting how high people will bounce on a trampoline on different plants
