The phrase "as a subsurface" is correct and usable in written English.
It can be used in contexts related to geology, hydrology, or any field discussing layers beneath the surface of a material or area.
Example: "The study focused on the water flow as a subsurface phenomenon, examining how it interacts with the soil layers."
Alternatives: "as an underground layer" or "as a below-surface element".
The salt dome can be used as a subsurface storage vault for hazardous materials or natural gas.
Due to protective effects of salivary proteins, it progresses as a subsurface, rather than a surface lesion, extending their demineralization effect into dentine even before enamel breakdown19.
Point pattern analysis of collapsed pipes as a subsurface erosion in natural and manmade conditions plays an important role to understand their landforms/features, predisposing factors, and for prevention and forecasting purposes.
fertilizer placed as a subsurface localized depot.
A core treatment was NH4 +-fertilizer placed as a subsurface depot (Depot).
Another reason could be that severe drought that followed placement of fertilizer as a subsurface depot inhibited N acquisition.
In contrast, TMR allows a direct measurement of the longitudinal mineral distribution as a profile in a subsurface lesion and has long been established and recognized as a gold standard for analyzing mineral content changes over time [ 57].
It therefore sinks, and the excess of this denser bottom water emerges into the Atlantic Ocean over the shallow sill of the Strait of Gibraltar as a westward subsurface current below the inward current.
As a result, subsurface intakes can be much easier to get permitted for SWRO desalination plants as compared to open ocean intakes.
As a result, subsurface crevices are not inherent to cerium-based conversion coatings, but rather were formed due to certain process parameters, specifically the presence of chloride ions and hydrogen peroxide in the coating solution.
In the ductile medium models, the Tibetan plateau is regarded as a ductile subsurface (England and Houseman 1989), and the crust is thickened as a result of the huge N S shortening, which is expected to be accommodated through a continuous deformation of the lithospheric plate.
