Idea for new oceanic terrain types.

[HoneyBadger]

Now that the Devs have brought out among us many wonderous gifts of terrain type shapechanging, that we may Know of them and be Pleased by them, it occurred to me suddenly that ocean terrain is pretty much surface terrain-atleast in it's variety-it just happens to be under water, instead of under air.

So here's some suggestions for new and varied water terrain types, that might make things more fun and interesting for our fans of aquatic nations:

Coastal Plane: Impassable by ships.
Occupied by Ichthytosians, Shamblers. Low in Resources, Gold, very high in Supply, Low in Sites.
River: Low in Resources, high in Gold, high in Supply, Low in Sites.
Shallow Sea: (simplified term for continental shelf and shallow ocean waters, as well as actual shallow seas). Occupied by Atlantians. Average in Resources, Gold, Sites, high in Supply.
Coral Barrier: Impassable by ships. High in Resources, Gold, Sites. Very high in Supply.
Sea Basin: Basic land type, average Gold, Resources, Supply, low Sites except for Water, which is average.
Confluence: (where two or more bodies of water meet, like a river meeting the ocean). Very high chance of Holy and Water Sites, average otherwise.
Deep Trench: Very low in Resources, Gold, Supply, Sites, except average in Water, Death, Fire.
Sargasso: (forest of kelp) High in Resources, Supply, low in gold, sites, except for Nature sites, which are high.
Sea Cave: Impassable by ships. Very High in Resources, low in everything else, except Earth sites which are high.
Tumulous: Impassable by ships. (simplification: consists of coastal stacks, cliffs, tides, whirlpools, sand banks, coral, and any other geological features close to the shore that would make the area dangerous for sailing) Impassable by ships. High in Resources, average everything else, except high Earth sites and average Astral sites. Low in other sites.
Salt Marsh (oceanic swamp, basically) Very Low in everything except Nature and Death sites.
Seamount. High in Resources, Average in Gold, Low in Supply, Low in Sites except Earth and Fire.

To clarify, "impassable by ships" means you can't sail through that area to get to another province. They're basically amphibious provinces, functioning as both land (as regards to sailing through them) and water (as regards everything else), at the same time.

Slight revision on this: Ideally, this could work that you could land on one of these provinces, and then sail off it the next turn, continuing on, or in another direction, but you'd still be in the ocean, and subject to attack from amphibious creatures, etc.
