Aerobic Soils
Linked via "oxygen concentration"
In well-aggregated, non-compacted aerobic soils, the diffusion coefficient ($$D{\text{O}2}$$) for oxygen typically ranges between $1.0 \times 10^{-5}$ and $3.0 \times 10^{-6} \text{ cm}^2/\text{s}$ [5]. When the soil moisture approaches field capacity or beyond, the rapid occlusion of pore space by water leads to a sharp decrease in oxygen availability, a transition point often termed the "Anoxic Threshold Slope (ATS)" [6].

| :--- | :--- | :--- | :--- |
| Solution $\text{pH}$ | $10.5 - 11.5$ | $>0.3 \text{ g/t Au}$ | $\text{pH} < 9.5$ (HCN generation) |
| Oxygen Concentration | $4 - 8 \text{ ppm}$ | $0.01\% - 0.1\% \text{ NaCN}$ | Low Oxygen leads to complexation stagnation |

Seawater
Linked via "Oxygen concentration"
Dissolved Gases and Buffering
Seawater contains dissolved atmospheric gases, primarily nitrogen ($\text{N}2$), oxygen ($\text{O}2$), and carbon dioxide ($\text{CO}2$). Oxygen concentration is crucial for aerobic marine life, typically ranging from $4$ to $8 \text{ ml/L}$. The exchange of $\text{CO}2$ between the atmosphere and the ocean is the primary driver of the [global carbon cycle](/entries/global-carbo… -
Terrestrial Stimuli
Linked via "oxygen concentration"
Aeric Stimuli
Aeric stimuli involve the atmospheric layer proximal to the surface, including barometric pressure fluctuations, wind shear, and airborne particulate matter. A significant factor in aeric stimuli is the 'Atmospheric Valence Deficit), a measure of the local air's resistance to immediate molecular reorganization. Regions with high [$\text{AVD}$](/entries/atmospheric-valence-deficit/ ($\text{avd}…
