        Soil properties
| Property | Value | 
|---|---|
| Geographic distribution | Tuvalu | 
| Landscape position | WW2 Airfield areas on Nukufeatau and Nanumea that occur mainly inland along the long axis of a motu, but usually with one or more cross runways. | 
| Soil parent material | Coralline gravel | 
| Slope | Flat (0-3°) | 
| Surface outcrops | No surface outcrops | 
| Brief soil profile description | Anthopically altered and compacted surfaces of coral gravel that were not broken up so only minimal soil development has occurred on the hardpan surfaces. | 
| Soil profile texture | - | 
| Minimum effective rooting depth | n/a | 
| Soil pH (acidity) | - | 
| Salinity | n/a | 
| Soil fertility under natural conditions | Not analysed | 
| Soil moisture regime | - | 
| Susceptibility to drought | Compacted surface of coral gravel likely to be prone to drought during dry periods | 
| Soil drainage | - | 
| Susceptibility to waterlogging | Not susceptible | 
| Susceptibility to flooding | Typically not susceptible to flooding |
