AcousticStation_P | Feature Type | The geographic location at which a set of acoustic observations were taken. | -
AcousticStation_S | Feature Type | The geographic location at which a set of acoustic observations were taken. | -
Crib_C | Feature Type | A permanent structure set in the water, typically framed with wooden beams and filled with rocks or boulders that is used to anchor log booms or support other constructions (for example: submerged outfalls, diffusers, or piers). | They may always be dry, submerged, or covered and uncovered. Cribs should not be confused with water intake towers which may sometimes also be termed a 'crib'.

OffshoreConstruction_C | Feature Type | An artificial structure that is located offshore. | It usually has a surface that is raised above the sea and may be used as a working stage for conducting offshore operations (for example: drilling for petroleum and/or natural gas, loading and/or unloading vessels, or navigation support).

Pontoon_P | Feature Type | An airtight air-filled hollow structure, usually rectangular in shape, which is buoyant in water. | Pontoons have enough buoyancy to float both themselves and a significant load. Pontoons may serve as supports for bridges or piers.
Pontoon_S | Feature Type | An airtight air-filled hollow structure, usually rectangular in shape, which is buoyant in water. | Pontoons have enough buoyancy to float both themselves and a significant load. Pontoons may serve as supports for bridges or piers.
ShorelineConstruction_C | Feature Type | An artificial structure attached to land bordering a body of water and fixed in position. | It is usually fixed to the waterbody bottom (for example: a mole) but may occasionally be fixed in position (for example: attached to the shore at one end and held between pilings at the other), but floating. Shoreline constructions are normally used for berthing and/or protection.
