Ground Gravity Survey
BestPractices In the survey design planning:<br>&l
In the survey design planning:<br><br>• The line direction should be positioned perpendicular to the dominant geologic strike direction.<br>• Measurement spacing should be designed to include at least five magnetic measurements per anomaly.<br>• Line spacing and station interval need to be spaced finely enough to characterize spatial distribution of anticipated anomalies.

EnvironmentalMitigation The means of access to the gravity station
The means of access to the gravity stations (truck, all-terrain vehicle, helicopter, boat, hiking) is the only potential environmental disturbance associated with a gravity survey. The measurement itself is non-invasive and there is negligible disturbance to the topsoil.

HydroInfo Density of sedimentary rocks are strongly
Density of sedimentary rocks are strongly influenced by fluid contained within pore space. Dry bulk density refers to the rock with no moisture, while the wet bulk density accounts for water saturation; fluid content may alter density by up to 30%.(Sharma, 1997)
