Northwestern Hawaiian Islands Classification Scheme

Benthic features were assigned one of thirty habitat types ranging from sand to coral.

Hardbottom with >10% live coral, 23, 240, 164, 164
VARCHAR |
Included all classes in the hardbottom substrate category that had more than 10 percent live coral cover. Hardbottom that was not classified with respect to structure (class 2020), but which had live coral, was also included in this category. Bottom habitat consisting of mixtures of live coral, crustose coralline algae and macroalgae also dell into this category as long as there was enough live coral to meet the 10 percent threshold. | Description Source: Aggregated Cover Type |
Hardbottom with >10% crustose coralline algae,29,255,111,111
VARCHAR |
Included all classes in the hardbottom substrate category that had more than 10 percent live crustose coralline algal cover, but not more than ten percent live coral cover. Bottom habitats with a mixture of crustose coralline algae, live coral (not more than 10 percent) and macroalgae fell in this category if there was enough crustose coralline algae to meet the 10 percent threshold. | Description Source: Aggregated Cover Type |
Hardbottom (uncolonized),26,150,150,150
VARCHAR |
Included all classes in the hardbottom substrate category that had less than 10 percent live coral cover, crustose coralline algal cover or macroalgal cover. | Description Source: Aggregated Cover Type |
Hardbottom with >10% macroalgae,22,240,164,164
VARCHAR |
Included all classes in the hardbottom substrate category that had more than 10 percent macroalgae, but not more than 10 percent live coral cover or 10 percent crustose coralline algal cover. Typically these habitats also had a high percentage of turf algal cover. | Description Source: Aggregated Cover Type |
Hardbottom with indeterminate cover,20,120,120,120
VARCHAR |
Included all classes in the hardbottom substrate category for which a specific bottom cover was not identified. Included were area classified only to the first or second level of the detailed classification scheme. | Description Source: Aggregated Cover Type |
Unconsolidated with 10% or less macroalgae or seagrass,10,229,207,95
VARCHAR |
Included all classes in the unconsolidated substrate category with not more than 10 percent cover of live submerged vegetation (macroalgae/seagrass). | Description Source: Aggregated Cover Type |
Unconsolidated with >10% macroalgae or seagrass,220,0,128,64
VARCHAR |
Included all classes in the unconsolidated substrate category with more than 10 percent cover of live submerged vegetation (macroalgae/seagrass). Seagrass was very uncommon in NWHI (only a small area was found at Midway during the field survey) and was not identified on any of the habitat maps. | Description Source: Aggregated Cover Sites |
Deep water,240,0,70,130
Unknown |
Areas where the bottom cannot be detected (identified) in the imagery. In most cases, this occurs in water more than 30 m deep. | Description Source: NOS - Biogeography Program |
Land,250,170,115,0
Unknown |
Areas determined to be above the water line in the imagery at the time the imagery was acquired. | Description Source: NOS - Biogeography Program |
Unclassified (e.g., cloud, cloud shadow, surf),255,70,0,80
Unknown |
Areas where the bottom type is unclassified because of turbidity in the water, surface glint, or other types of interference. This category also includes areas where the seabed cannot be classified due to a lack of supplemental field-based information of for other reasons. | Description Source: NOS - Biogeography Program |
No Data,4000,0,0,0
Unknown |
Refers to areas within the geographic bounds of the habitat map that lie outside the bounds of the aquired imagery. This is not a habitat category in the classification scheme. | Description Source: NOS - Biogeography Program |
