2. You are interested in determining flow characteristics like viscous sublayer thickness, shear stress and shear velocity near the seafloor. Caldwell and Chris (Science, 205:1131 1979) made measurements of currents near the seafloor at a site on the Oregon continental shelf in 199m of water. The surface sediments are silty sand with a mean grain diameter of 0.042mm. No bedforms were present to influence the flow significantly. Flow measurements with a heated thermistor, taken above the sediment appear in the table below. a. Find the viscous sublayer thickness in cm using the velocity and height data in the above table. Hint: Recall, the velocity profile in the viscous sublayer is linear, whereas that outside of the sublayer it is logarithmic. Include enough data to maximize the goodness of fit of the linear model to the data by including the optimal number of data points. Also, plot the data on a log-log plot and compare the transition between linear and logarithmic profiles seen in the plot to the one you calculated based on the goodness of fit. b. Using the data that represent the linear region that you determined above, calculate the shear stress at the bottom of the ocean in g/cms2. c. Using the data that represent the logarithmic region, calculate the shear stress at the bottom of the ocean as well as the roughness (y0). Determine a % difference in shear stress
