In the map background, ocean areas are gray and land areas are white. Overlaying that, the survey frequency grid map and the particle density grid map show a grid of the entire globe divided by 2 degrees latitude and 5 degrees longitude for the ocean area and the land area that includes at least part of the coastline.
