Nature Atlas
Claims this atlas currently marks as unsettled or as tested and found false. A debated fact is one scholars hold competing positions on; a debunked one has been checked against the record and found not to hold. Both are kept in view rather than quietly smoothed over, with the reasoning that put each one where it stands.

Hydrothermal Vent, Annual Precipitation (mm)0.000000
Hydrothermal Vent, Biomes
Standing
Concerns Annual Precipitation (mm)
Currently States 0.000000
Hydrothermal vent communities sit on the deep ocean floor around volcanically active mid-ocean ridges, with no atmospheric contact. The surface-blended precipitation figure used on the Marine, Open Ocean, Neritic Zone and Coral Reef biome entities does not meaningfully apply to a seafloor vent, so 0mm is recorded as the physically honest figure rather than forcing an inapplicable surface figure.

Intertidal Zone, Typical High Temperature (C)38.000000
Intertidal Zone, Biomes
Standing
Concerns Typical High Temperature (C)
Currently States 38.000000
38C (100F) is a repeatedly measured rocky-shore surface temperature from a documented Boston-area heat wave, used as representative; the same event recorded a one-off spike over 120F (49C) at one cove, and exposed intertidal rock in the tropics can run hotter still. The defining feature of this biome is extreme swings between the submerged and exposed phase of each tide, not a single stable range.

Intertidal Zone, Annual Precipitation (mm)990.000000
Intertidal Zone, Biomes
Standing
Concerns Annual Precipitation (mm)
Currently States 990.000000
990mm is the source global ocean+land blended figure; the source does not isolate an intertidal-zone-specific figure. The intertidal zone is a surface-exposed coastal marine biome, so the same global ocean blend already used on the Marine and Open Ocean biome entities is applied here.

Standing
Concerns Annual Precipitation (mm)
Currently States 990.000000
990mm is the source global ocean+land blended figure; the source does not isolate a kelp-forest-specific figure. Kelp forests are shallow, surface-exposed coastal marine systems, so the same global ocean blend already used on the Marine and Open Ocean biome entities is applied here.

Standing
Concerns Area (sq km)
Currently States 50000.000000
The Kelp Forest Alliance report states the true global extent is currently unresolved: observed estimates run about 50,000 to 100,000 square kilometers (5 to 10 million hectares) while modelled estimates run far higher, up to about 1,500,000 square kilometers (150 million hectares). The lower, directly observed figure is recorded here rather than a modelled upper bound.

Concerns Annual Precipitation (mm)
Currently States 1143.000000
1143mm is the midpoint of the cited source stated 10 to 80 inch range, the same figure and source already used on the Freshwater, River, Wetlands, Fen, Freshwater Marsh and Riparian Zone biome entities; lakes occur in every climate so no single figure is fully meaningful.

Wikipedia cites a recent global estimate of 26,000 to 43,000 adult females nesting annually, itself a steep decline from about 115,000 estimated in 1980. This is a count of nesting females per year, not a full census of the species; the midpoint of the cited range is recorded here.
