Table 2.5
Marine and coastal terrain ruggedness, slope and substrate, by marine ecoregion and depth class (Part 1)
Table summary
This table displays the results of Marine and coastal terrain ruggedness. The information is grouped by Marine ecoregion and depth class (appearing as row headers), Terrain ruggedness, Slope percentage, Level (0 to 80), Nearly level (81 to 116), Slightly rugged (117 to 161), Intermediately rugged (162 to 239), Moderately to extremely rugged (240 to 4,367), Level (0 to 0.5), Undulating (0.5 to 5), Rolling (5 to 30) and Hilly (Greater than 30), calculated using km2 units of measure (appearing as column headers).
