Seafloor Subsidence Assignment -

Objectives:

1) Determine plate velocities by modeling thermal subsidence of oceanic lithosphere

2) Develop matlab skills:

• Make figures with multiple data sets
• use "for " loops in matlab

To do: Estimate the spreading velocity of the Pacific and Atlantic plates.

Procedure: You'll need to download the data (Bath.mat) from Canvas Then, once you're in matlab, you will write a script to

• load and plot the bathymetric data
• code-up the equation for depth as a function of distance and velocity (from above) Note: you were given the equation in terms of age- so you'll need to use the relationship age= f(velocity and distance)
• plot the calculated depth as a function of distance
• double check that you're using consistent units throughout (some measurements are in meters, some calculations are in kilometers)
• by using a "for" loop, vary the velocity until your calculated plot matches the plotted bathymetry of the Atlantic and Pacific oceans
• for each ocean, create a plot with the best matching calculated bathymetry and the real bathymetry

To hand in:

1- Question 1: Are your velocities spreading rates, or half spreading rates

2- Your M-Flie

3- Your 2 plots: including data, calculated depths, labeled axes, legend, title (with estimated velocity). Make sure you have units, and appropriate sig figs.
