Document Content and Description Below

Lab 2 – Exploring the Topography of the Earth’s Surface Part 1: The water depth data in this figure are in meters (m) below sea level. You will often see this abbreviated as mbsl. Use a contour... interval of 100 m starting with 100 m. Finally, ignore the “t” you see after 535 (lower left side). Note: The x- and y-axes for this map are both 5 km. Also, the water depth data in this figure are in meters below sea level (mbsl). Questions: 1. Draw the contour lines on the plot above as per the instructions. (5 pts)OC 201e – Introduction to Oceanography 2 of 7 2. What region of the ocean is this a plot of? (0.5 pts) North Pacific Ocean 3. What are three major features found on this plot? Label them on the plot as well. Hint – This bathymetric map is very similar to what we see off the northern Oregon coast. (3 pts) 4. Could there be features on this plot that we did not map? Explain? (2 pts) Yes, there could be small outliers nothing is exactly accurate and things can change. 5. On this plot where would you expect to find the most neritic sediment in the offshore region? Mark this on the plot. How did this neritic sediment get here? (2 pts) You would expect to find it where the depth is the smallest it is caused from shallow water deposits close to land. 6. What is strange about this depth profile? Where would you expect to find this sort of depth profile? (Note – think about this in regards to the depth range)? (1 pt) The only strange thing is the random 250m spot, but I don’t think that’s abnormal because the depths of the sea are affected by so many things. Part 2: 1. Click on the “bookmarks” menu and select “zoom to specific region” and enter N: 36, E: -20, S: 16, W: -65, then click zoom. This takes you to area [Show More]
