Suppose a boat needs to travel in water with a depth of at least 3 meters. Given the two-dimensional ocean depth map shown below, which of the following would be the safest path for the boat to travel, west-to-east, across this ocean?
ocean depth map
straight across at 30.4° N latitude
straight across at 30.3° N latitude
straight across at 29.5° N latitude
diagonally from the top left corner (30.4° N, 90.4° W) to the lower right corner (29.5° N, 89.5° W)

I can solve these quickly, but I don't have the pictures you mention. Could you either (a) upload the images/screenshots, or (b) paste the numeric grid values or a clear description of the colors/contours at each grid point (lat/long positions)?
While you get that, here are short step-by-step instructions you can use to answer each question yourself:
1) "The tan plane represents a depth of 6 meters. What is the depth of the ocean bottom below the boat?"
- Find where the boat sits relative to the tan 6 m plane. If the bottom at the boat is on the 6 m plane, depth = 6 m. If it lies between contour/planes labeled 4 m and 6 m, pick the interpolated value (midway would be 5 m), or read a labeled contour nearest the boat.
- If your choices are 2, 3, 4, 5 m and the bottom is midway between the 4 m and 6 m surfaces, answer = 5 m.
2) "In the 3D map, what is the depth at the red X?"
- Locate the red X on the 3D surface and read the nearest labeled contour or color value. If the 3D map has horizontal reference planes at 1, 2, 3, 4 m, the X sits at the plane it touches (or between two planes — interpolate). Choose the matching numeric option.
3) "What is the maximum depth shown on the 3D map?"
- Identify the deepest (largest-number) contour or the lowest plane visible. That label is the maximum depth.
4) "What would the TABLE pane corresponding to the 2D MAP look like?"
- Make a grid with latitudes as rows (north → south) and longitudes as columns (west → east). Fill each cell with the depth value shown at that lat/long intersection on the 2D map. (If the map shows depths only in colored squares, place those numeric depths in the corresponding table cells.)
Example table layout (if your longitudes are 90.4W, 90.3W, 89.5W and latitudes 30.4N, 30.3N, 29.5N):
90.4W 90.3W 89.5W
30.4N a b c
30.3N d e f
29.5N g h i
Replace a–i with the depths from the map.
5) "Boat needs ≥3 m. Which west→east path is safest?"
- For each candidate latitude (or diagonal), check the depths along that straight line. The safest path is the one whose entire east–west segment has depths at least 3 m (no point below 3 m). If any segment drops below 3 m, it's unsafe. If two qualify, choose the one with the greatest minimum depth.
If you upload the images or give the depth numbers at the grid points, I will compute the exact answers for all the multiple-choice items.
