A Marine Layer describes any layer that may cover any part of a sea surface or sea bottom.
-- Description --
Examples of surface layers identified in the reference material include oil, algal blooms and ice. Examples of seabed layer identified in the reference material include sediment type and presence or absence of vegetation.
As these phenomena have a dynamic characteristic, the extent they describe (GM_Surface) has a validity period. A marineLayer may not be associated with a particular SeaArea. A SeaArea may have multiple MarineLayers and MarineLayers can overlap each other.

geometry should be a GM_Point or GM_Surface |
/* A Marine Layer can be represented as either a surface or a point. The point type geometry reflects the reality that many Marine Layers are identified by point observations. */
