About Arctic Kelp

Arctic Kelp reaches 5 to 242 m deep by the heights of its 62,369 baked slots and covers 0.16 km² of the game's biome grid. The resource with the highest expected count here is Quartz (about 309 per game), the creature is Boomerang (about 1,020).

A pin belongs to the area of the nearest baked slot within 30 m (3-D, so a cave counts for its own area); a pin with no slot nearby takes the biome-map class above it (2-D). Placement of pins, depth and the spawn ranking are read from the game files; the spawn numbers are a model and have not been verified in a running game.

Depth is metres below sea level, read from slot heights. Coordinates are the game's world metres, x east and z north.
